侧齿轮

Side gears are essential differential components that transfer torque to axle shafts, enabling smooth vehicle turning.

技术定义与适配语境
典型 侧齿轮 会按材料、尺寸公差、适配关系和失效风险在 汽车制造 中评估。

Side gears are bevel gears located within a differential assembly, typically meshing with pinion gears to distribute rotational force from the driveshaft to the axle shafts. They play a critical role in allowing wheels to rotate at different speeds during cornering while maintaining torque delivery.

定义
Side gears are bevel gears located within a differential assembly, typically meshing with pinion gears to distribute rotational force from the driveshaft to the axle shafts. They play a critical role in allowing wheels to rotate at different speeds during cornering while maintaining torque delivery.
工作原理
Side gears operate on the principle of torque distribution through bevel gear meshing. When a vehicle turns, the differential allows the outer wheel to rotate faster than the inner wheel. The side gears, connected to the axle shafts, rotate at different speeds relative to each other while still receiving torque from the ring gear via the pinion gears, ensuring smooth power transfer and minimizing tire wear.
材料
Typically forged or machined from high-strength alloy steels such as SAE 86204140or 4340often case-hardened through carburizing or nitriding to achieve surface hardness of 58-62 HRC with a tough core.

常见问题

What is the primary function of a side gear in a differential?

The side gear transfers torque from the differential case to the axle shafts, allowing wheels to rotate at different speeds during turns while maintaining power delivery.

Can side gears be replaced individually?

Typically, side gears are replaced as part of a matched set with pinion gears to ensure proper meshing and wear patterns, though individual replacement is possible if specifications are precisely matched.

What are common failure modes for side gears?

Common failures include tooth pitting, spalling, wear due to inadequate lubrication, and fracture from excessive torque or impact loads.
