Working Principle

Single reduction gear is a driving bevel gear (commonly known as angular gear) and a basin angle gear pair. The driving bevel gear is connected with the transmission shaft, rotates clockwise, sticks to its right side from the bevel gear, and rotates downward at the meshing point, which is consistent with the CHINAMFG direction of the wheel. Due to the small diameter of the driving bevel gear and the large diameter of the bevel gear, the function of deceleration is achieved.
The double reduction has an additional intermediate transition gear.The left side of the driving bevel gear is meshed with the bevel gear of the intermediate gear. The bevel gear is coaxial with a spur gear with small diameter, and the spur gear is meshed with the driven gear. In this way, the intermediate gear rotates backward and the driven gear rotates forward. There is a two-stage deceleration process in the middle.
Due to the increase of axle volume, double reduction was mainly used in vehicles with low engine power in the past, mainly in construction machinery with low speed and high torque.
In the double reduction final drive, if the second-stage deceleration is carried out near the wheel, it actually constitutes an independent part at the 2 wheels, it is called wheel reducer. The advantage of this is that the torque transmitted by the half shaft can be reduced, which is conducive to reducing the size and quality of the half shaft. The wheel reducer can be planetary gear type or composed of a pair of cylindrical gear pairs. When the cylindrical gear pair is used for wheel side deceleration, the up-down position relationship between the wheel axis and the half shaft can be changed by adjusting the mutual position of the 2 gears. This kind of axle is called portal axle, which is often used for vehicles with special requirements for the high and low position of the axle.
According to the number of the main reducer transmission ratio, it can be divided into single-speed and double-speed. 
Domestic cars basically adopt single speed main reducer with fixed transmission ratio. On the double reduction final drive, there are 2 transmission ratios for selection, and this main reducer actually acts as an auxiliary transmission.

How does a crown gear handle variations in rotational direction?

Crown gears are versatile components that can effectively handle variations in rotational direction. Let’s delve into how crown gears accommodate changes in rotational direction:

  • Bidirectional Capability:

Crown gears are designed to operate in either direction of rotation. Unlike other gear types that have a preferred rotational direction, such as spur gears or helical gears, crown gears can handle variations in rotational direction without any issues. This bidirectional capability makes crown gears suitable for applications where the direction of rotation may change or reverse periodically.

  • Symmetrical Tooth Profile:

Crown gears have a symmetrical tooth profile, which means the shape and orientation of the teeth remain the same regardless of the rotational direction. This symmetrical tooth profile enables the gear to engage and mesh with other gears consistently, irrespective of the direction of rotation. The symmetrical design ensures that the gear teeth align correctly and maintain proper contact and meshing, regardless of the rotational direction.

  • Uniform Load Distribution:

The curved tooth profile of crown gears allows for uniform load distribution across the gear teeth. This characteristic is beneficial when encountering variations in rotational direction. Regardless of the direction of rotation, the load is distributed evenly over the gear teeth, preventing localized stress concentrations and promoting balanced power transmission. The uniform load distribution helps ensure smooth operation and reduces the risk of premature wear or failure.

  • Backlash Compensation:

Crown gears can compensate for backlash, which is the slight clearance or play between the teeth of meshing gears. When encountering changes in rotational direction, the crown gear’s tooth orientation and engagement properties help minimize or eliminate backlash. By mitigating backlash, crown gears maintain a tighter meshing with other gears, reducing any potential impact on the system’s performance and accuracy.

In summary, crown gears handle variations in rotational direction by their bidirectional capability, symmetrical tooth profile, uniform load distribution, and backlash compensation. These characteristics make crown gears versatile and reliable components in gear systems where changes in rotational direction are expected or required.

What are the challenges in designing and manufacturing crown gears?

The design and manufacturing of crown gears come with certain challenges that engineers and manufacturers need to address. Let’s explore the challenges involved in designing and manufacturing crown gears:

  • Complex Tooth Geometry:

Crown gears have a complex tooth geometry compared to other gear types. The curved shape of the teeth requires precise calculations and design considerations to ensure proper meshing and optimal performance. Designing and modeling these intricate tooth profiles can be challenging, requiring advanced software tools and expertise.

  • Manufacturing Tolerances:

Manufacturing crown gears with tight tolerances is crucial to achieve smooth and accurate meshing with other gears. The curved tooth profile and perpendicular orientation require precise machining or gear cutting processes. Maintaining the necessary tolerances throughout the manufacturing process can be challenging and may require specialized equipment or techniques.

  • Noise and Vibration:

Due to the complex tooth geometry and meshing characteristics, crown gears can generate noise and vibration during operation. Ensuring quiet and vibration-free performance is essential, especially in applications where noise reduction is critical. Designing and manufacturing crown gears with appropriate tooth profiles, surface finishes, and gear materials can help mitigate noise and vibration issues.

  • Stress Concentrations:

Crown gears are susceptible to stress concentrations at the tooth root and fillet areas. The high contact stresses occurring during meshing can lead to premature tooth failure or wear. Designing proper fillet radii, optimizing tooth profiles, and selecting suitable materials and heat treatments are important considerations to minimize stress concentrations and enhance gear strength and durability.

  • Heat Treatment and Surface Hardening:

Achieving the desired surface hardness and wear resistance of crown gears can be challenging. Heat treatment processes, such as carburizing or induction hardening, need to be carefully controlled to ensure uniform hardness distribution and avoid distortion. Balancing the gear’s core toughness with the surface hardness is critical to maintain gear integrity and performance.

  • Lubrication and Maintenance:

Crown gears require proper lubrication to reduce friction, wear, and heat generation during operation. Designing gear systems with adequate lubrication mechanisms, such as oil baths or forced lubrication, is crucial. Additionally, considering maintenance requirements, such as accessibility for lubrication and gear inspection, is important to ensure the long-term performance and reliability of crown gears.

In summary, designing and manufacturing crown gears present challenges related to complex tooth geometry, manufacturing tolerances, noise and vibration, stress concentrations, heat treatment, surface hardening, lubrication, and maintenance. Overcoming these challenges requires careful design considerations, precise manufacturing processes, and suitable material selection to ensure the optimal performance, durability, and reliability of crown gears in gear systems.
