Product Description

(1) The accuracy of oil seal, spigot, steel ring is 1/3 higher than that of the market wheel reducer. For example, the tolerance of Fukai oil seal is 0 ~ 8 wires, and the tolerance of ordinary wheel reducer is 0 ~ 15 wires.
(2) The disk surface is drilled through the reamer, and the position of the tire hole is checked with the inspection tool disk to ensure the consistency of the hole diameter and the perfection of concentricity.
(3) In order to prevent the possibility of oil leakage of 1/10000, the machining center adopts the processing technology of rough boring and fine boring for the shaft hole; The 10 threaded holes at the bottom of the wheel hub reducer housing are all blind holes (most of the wheel hub reducer housing on the market are through holes).
(4) When drilling the legs of the wheel rim planet carrier, in order to prevent the angle from being slanted when the hole is deep, which may reduce the service life of the planet carrier after assembling the wheel rim assembly, the wheel hub reducer housing of Fukai brand is drilled and positioned 2.5mm in the machining center first, and then the vertical drilling is completed (most brands of planet carriers are made directly at 1 time).
(5) After the wheel rim is formed, it will be polished 1 by 1 with metallographic instrument, and then inspect each product on delivery to ensure the stability of the material of each product.
(6) The gear, planetary shaft, planetary gasket, needle roller bearing, stabilizing pin and wheel edge screw equipped with the wheel reducer assembly are the original products, with fine appearance and reliable quality.
(7) Steyr wheel reducer assembly is improved from the original bearing type to the needle roller type to prevent damage to the wheel reducer assembly caused by the wear of the bearing frame, and greatly improve the service life of the wheel reducer assembly.
(8) Fukai brand wheel reducer assembly is equipped with repair kits required for maintenance (including circlips, adjusting gaskets, wheel oil plugs, sun gear gaskets, gloves, etc.)

Working Principle

The wheel reducer is mainly composed of sun gear, planetary gear, ring gear and planetary gear carrier. Generally, the sun gear of the driving part is connected with the half shaft, the planetary gear carrier of the passive part is connected with the wheel, and the ring gear is connected with the axle housing. The wheel reducer is used to increase the driving force matching of the car to meet or modify the force of the entire transmission system. At present, the wheel reducer is a set of gear transmission device with speed reduction and torque increase to meet the matching needs of the whole transmission system. The power is transmitted from the engine to the main reducer of the front and rear axle through the clutch, transmission and transfer case, and then from the output end of the main reducer to the wheel reducer and wheels to drive the vehicle. In this process, the working principle of the wheel reducer is to transfer the speed and torque transmitted by the main reducer to the wheels after its speed reduction and torque increase, so the wheels can generate a large driving force under the reaction of ground adhesion. Thus, the stress of each part in front of the wheel reducer is reduced.

axle hub

What is the primary function of an axle hub in a vehicle’s wheel assembly?

The primary function of an axle hub in a vehicle’s wheel assembly is to connect the wheel to the axle and provide a mounting point for the wheel bearings. Here’s a detailed explanation of the primary functions of an axle hub:

1. Wheel Mounting:

The axle hub serves as the component that connects the wheel to the vehicle’s axle. It is typically a cylindrical or disc-shaped structure located at the center of the wheel assembly. The hub contains bolt holes or studs that align with the corresponding holes or studs on the wheel, allowing for secure attachment and proper alignment of the wheel.

2. Bearing Support:

The axle hub provides a mounting point for the wheel bearings. Wheel bearings are crucial components that allow the wheel to rotate smoothly while supporting the weight of the vehicle. The hub contains a bearing race or races, which are machined surfaces that support the inner and outer wheel bearings. The bearings fit snugly into the hub and enable the wheel to rotate freely around the axle.

3. Load Transmission:

Another important function of the axle hub is to transmit the load from the wheel to the axle. As the vehicle moves, various forces act on the wheel, including the weight of the vehicle, acceleration and braking forces, and lateral forces during turns. The axle hub, along with the wheel bearings, helps distribute and transfer these forces from the wheel to the axle, allowing for smooth and controlled movement of the vehicle.

4. Hub Assembly Integration:

In many vehicles, the axle hub integrates with other components of the wheel assembly. For example, it may have provisions for attaching the brake rotor or drum, which are essential for the vehicle’s braking system. In vehicles with front-wheel drive or all-wheel drive, the axle hub may also incorporate features for connecting the CV (constant velocity) joint or driveshaft, allowing for power transmission to the wheels.

5. Wheel Alignment:

The axle hub plays a role in maintaining proper wheel alignment. The hub’s design and dimensions are critical in ensuring that the wheel is centered and aligned correctly with the vehicle’s suspension system. Proper wheel alignment is essential for optimal handling, tire wear, and overall vehicle performance.

In summary, the primary function of an axle hub in a vehicle’s wheel assembly is to connect the wheel to the axle and provide a mounting point for the wheel bearings. It facilitates the secure attachment of the wheel, supports the wheel bearings for smooth rotation, transmits loads from the wheel to the axle, integrates with other components of the wheel assembly, and contributes to proper wheel alignment. The axle hub is a critical component that enables safe and efficient operation of the vehicle’s wheels.

What role does the ABS sensor play in the context of an axle hub assembly?

The ABS (Anti-lock Braking System) sensor plays a crucial role in the context of an axle hub assembly. It is an integral component of the braking system and is responsible for monitoring the speed and rotational behavior of the wheels. Here’s a detailed explanation of the role of the ABS sensor in the context of an axle hub assembly:

  • Wheel speed monitoring: The primary function of the ABS sensor is to monitor the rotational speed of the wheels. It does this by detecting the teeth or magnetic patterns on a tone ring or reluctor ring mounted on the axle hub or adjacent to the wheel hub. By continuously measuring the speed of each wheel, the ABS sensor provides crucial data to the vehicle’s ABS system.
  • Anti-lock Braking System (ABS): The ABS system utilizes the data provided by the ABS sensors to determine if any wheel is about to lock up during braking. If a wheel is on the verge of locking up, the ABS system modulates the braking pressure to that wheel. This prevents the wheel from fully locking up, allowing the driver to maintain control of the vehicle and reducing the risk of skidding or loss of steering control.
  • Traction control: In addition to aiding the ABS system, the ABS sensors also play a role in the vehicle’s traction control system. By continuously monitoring the rotational speed of the wheels, the ABS sensors assist in detecting any wheel slippage or loss of traction. When a wheel slips, the traction control system can adjust the engine power output or apply brake pressure to the specific wheel to regain traction and maintain stability.
  • Stability control: Some modern vehicles incorporate stability control systems that rely on the ABS sensors to monitor the rotational behavior of the wheels. By comparing the speeds of individual wheels, the stability control system can detect and mitigate any potential loss of vehicle stability. This may involve applying brakes to specific wheels or adjusting engine power to help the driver maintain control in challenging driving conditions or during evasive maneuvers.
  • Diagnostic capabilities: The ABS sensors also provide diagnostic capabilities for the vehicle’s onboard diagnostic system. In the event of a fault or malfunction within the ABS system, the ABS sensors can transmit error codes to the vehicle’s computer, which can then be retrieved using a diagnostic scanner. This aids in the identification and troubleshooting of ABS-related issues.

The ABS sensor is typically mounted near the axle hub, with its sensor tip in close proximity to the tone ring or reluctor ring. It generates electrical signals based on the detected rotational patterns, which are then transmitted to the vehicle’s ABS control module for processing and action.

In summary, the ABS sensor plays a vital role in the context of an axle hub assembly. It monitors the rotational speed of the wheels, providing essential data for the ABS system, traction control, and stability control. The ABS sensor helps prevent wheel lockup during braking, enhances traction in slippery conditions, aids in maintaining vehicle stability, and contributes to the diagnostic capabilities of the ABS system.

What is the importance of proper lubrication in maintaining a healthy axle hub?

Proper lubrication plays a crucial role in maintaining a healthy axle hub and ensuring its optimal performance and longevity. Here’s a detailed explanation:

An axle hub consists of several components, including wheel bearings, seals, and other internal parts. These components are subjected to high loads, friction, and heat generated during normal vehicle operation. Lubrication is essential to reduce friction, dissipate heat, and provide a protective barrier between moving parts. Here are the key reasons why proper lubrication is important for maintaining a healthy axle hub:

  • Reduced Friction: Adequate lubrication reduces friction between the moving parts of the axle hub. This minimizes wear and tear on the components and helps them operate smoothly. By reducing friction, proper lubrication helps prevent premature failure of critical parts, such as the wheel bearings.
  • Heat Dissipation: Axle hubs generate heat during operation due to the friction between the rotating components. The lubricant acts as a coolant, helping to dissipate heat and prevent excessive temperature buildup. Proper lubrication ensures that the heat is effectively managed, preventing overheating and potential damage to the axle hub.
  • Corrosion Prevention: Axle hubs are exposed to various environmental elements, including moisture, dirt, and road contaminants. These can lead to corrosion and rust, compromising the performance and structural integrity of the axle hub. Lubrication creates a protective barrier, preventing moisture and contaminants from reaching the critical components and reducing the risk of corrosion.
  • Seal Integrity: Proper lubrication helps maintain the integrity of the seals in the axle hub. Seals play a vital role in preventing the entry of contaminants and retaining the lubricant within the hub assembly. Insufficient lubrication can cause the seals to deteriorate prematurely, leading to lubricant leakage and potential damage to the axle hub.
  • Noise Reduction: Well-lubricated axle hubs operate quietly. The lubricant creates a cushioning effect, reducing noise and vibrations generated by the rotating components. This helps provide a comfortable and quiet driving experience.

It’s important to note that different axle hubs may require specific types of lubricants, such as grease or oil, depending on the design and manufacturer’s recommendations. Using the correct lubricant and following the specified lubrication intervals are crucial for maintaining a healthy axle hub. Over-lubrication or under-lubrication can lead to issues such as excess heat buildup, component damage, or inadequate protection.

Regular maintenance and inspection of the axle hub, including checking the lubricant level and quality, are essential. If any signs of contamination, leakage, or inadequate lubrication are observed, appropriate action should be taken, such as replenishing or replacing the lubricant and addressing any underlying issues.

In summary, proper lubrication is vital for maintaining a healthy axle hub. It reduces friction, dissipates heat, prevents corrosion, maintains seal integrity, and reduces noise. Adequate lubrication ensures smooth operation, prolongs the lifespan of the components, and helps prevent premature failures. Following the manufacturer’s recommendations regarding lubricant type and maintenance intervals is crucial for optimal axle hub performance and longevity.

How to Determine the Quality of a Worm Shaft

There are many advantages of a worm shaft. It is easier to manufacture, as it does not require manual straightening. Among these benefits are ease of maintenance, reduced cost, and ease of installation. In addition, this type of shaft is much less prone to damage due to manual straightening. This article will discuss the different factors that determine the quality of a worm shaft. It also discusses the Dedendum, Root diameter, and Wear load capacity.
worm shaft

Root diameter

There are various options when choosing worm gearing. The selection depends on the transmission used and production possibilities. The basic profile parameters of worm gearing are described in the professional and firm literature and are used in geometry calculations. The selected variant is then transferred to the main calculation. However, you must take into account the strength parameters and the gear ratios for the calculation to be accurate. Here are some tips to choose the right worm gearing.
The root diameter of a worm gear is measured from the center of its pitch. Its pitch diameter is a standardized value that is determined from its pressure angle at the point of zero gearing correction. The worm gear pitch diameter is calculated by adding the worm’s dimension to the nominal center distance. When defining the worm gear pitch, you have to keep in mind that the root diameter of the worm shaft must be smaller than the pitch diameter.
Worm gearing requires teeth to evenly distribute the wear. For this, the tooth side of the worm must be convex in the normal and centre-line sections. The shape of the teeth, referred to as the evolvent profile, resembles a helical gear. Usually, the root diameter of a worm gear is more than a quarter inch. However, a half-inch difference is acceptable.
Another way to calculate the gearing efficiency of a worm shaft is by looking at the worm’s sacrificial wheel. A sacrificial wheel is softer than the worm, so most wear and tear will occur on the wheel. Oil analysis reports of worm gearing units almost always show a high copper and iron ratio, suggesting that the worm’s gearing is ineffective.

Dedendum

The dedendum of a worm shaft refers to the radial length of its tooth. The pitch diameter and the minor diameter determine the dedendum. In an imperial system, the pitch diameter is referred to as the diametral pitch. Other parameters include the face width and fillet radius. Face width describes the width of the gear wheel without hub projections. Fillet radius measures the radius on the tip of the cutter and forms a trochoidal curve.
The diameter of a hub is measured at its outer diameter, and its projection is the distance the hub extends beyond the gear face. There are 2 types of addendum teeth, 1 with short-addendum teeth and the other with long-addendum teeth. The gears themselves have a keyway (a groove machined into the shaft and bore). A key is fitted into the keyway, which fits into the shaft.
Worm gears transmit motion from 2 shafts that are not parallel, and have a line-toothed design. The pitch circle has 2 or more arcs, and the worm and sprocket are supported by anti-friction roller bearings. Worm gears have high friction and wear on the tooth teeth and restraining surfaces. If you’d like to know more about worm gears, take a look at the definitions below.
worm shaft

CZPT’s whirling process

Whirling process is a modern manufacturing method that is replacing thread milling and hobbing processes. It has been able to reduce manufacturing costs and lead times while producing precision gear worms. In addition, it has reduced the need for thread grinding and surface roughness. It also reduces thread rolling. Here’s more on how CZPT whirling process works.
The whirling process on the worm shaft can be used for producing a variety of screw types and worms. They can produce screw shafts with outer diameters of up to 2.5 inches. Unlike other whirling processes, the worm shaft is sacrificial, and the process does not require machining. A vortex tube is used to deliver chilled compressed air to the cutting point. If needed, oil is also added to the mix.
Another method for hardening a worm shaft is called induction hardening. The process is a high-frequency electrical process that induces eddy currents in metallic objects. The higher the frequency, the more surface heat it generates. With induction heating, you can program the heating process to harden only specific areas of the worm shaft. The length of the worm shaft is usually shortened.
Worm gears offer numerous advantages over standard gear sets. If used correctly, they are reliable and highly efficient. By following proper setup guidelines and lubrication guidelines, worm gears can deliver the same reliable service as any other type of gear set. The article by Ray Thibault, a mechanical engineer at the University of Virginia, is an excellent guide to lubrication on worm gears.

Wear load capacity

The wear load capacity of a worm shaft is a key parameter when determining the efficiency of a gearbox. Worms can be made with different gear ratios, and the design of the worm shaft should reflect this. To determine the wear load capacity of a worm, you can check its geometry. Worms are usually made with teeth ranging from 1 to 4 and up to twelve. Choosing the right number of teeth depends on several factors, including the optimisation requirements, such as efficiency, weight, and centre-line distance.
Worm gear tooth forces increase with increased power density, causing the worm shaft to deflect more. This reduces its wear load capacity, lowers efficiency, and increases NVH behavior. Advances in lubricants and bronze materials, combined with better manufacturing quality, have enabled the continuous increase in power density. Those 3 factors combined will determine the wear load capacity of your worm gear. It is critical to consider all 3 factors before choosing the right gear tooth profile.
The minimum number of gear teeth in a gear depends on the pressure angle at zero gearing correction. The worm diameter d1 is arbitrary and depends on a known module value, mx or mn. Worms and gears with different ratios can be interchanged. An involute helicoid ensures proper contact and shape, and provides higher accuracy and life. The involute helicoid worm is also a key component of a gear.
Worm gears are a form of ancient gear. A cylindrical worm engages with a toothed wheel to reduce rotational speed. Worm gears are also used as prime movers. If you’re looking for a gearbox, it may be a good option. If you’re considering a worm gear, be sure to check its load capacity and lubrication requirements.

NVH behavior

The NVH behavior of a worm shaft is determined using the finite element method. The simulation parameters are defined using the finite element method and experimental worm shafts are compared to the simulation results. The results show that a large deviation exists between the simulated and experimental values. In addition, the bending stiffness of the worm shaft is highly dependent on the geometry of the worm gear toothings. Hence, an adequate design for a worm gear toothing can help reduce the NVH (noise-vibration) behavior of the worm shaft.
To calculate the worm shaft’s NVH behavior, the main axes of moment of inertia are the diameter of the worm and the number of threads. This will influence the angle between the worm teeth and the effective distance of each tooth. The distance between the main axes of the worm shaft and the worm gear is the analytical equivalent bending diameter. The diameter of the worm gear is referred to as its effective diameter.
The increased power density of a worm gear results in increased forces acting on the corresponding worm gear tooth. This leads to a corresponding increase in deflection of the worm gear, which negatively affects its efficiency and wear load capacity. In addition, the increasing power density requires improved manufacturing quality. The continuous advancement in bronze materials and lubricants has also facilitated the continued increase in power density.
The toothing of the worm gears determines the worm shaft deflection. The bending stiffness of the worm gear toothing is also calculated by using a tooth-dependent bending stiffness. The deflection is then converted into a stiffness value by using the stiffness of the individual sections of the worm shaft. As shown in figure 5, a transverse section of a two-threaded worm is shown in the figure.
