The working principle of automobile reducer?

Reducer is the main component in the transmission system to reduce the speed and increase the torque, through the gear with fewer teeth to drive the gear with more teeth to realize the deceleration, the use of bevel gear transmission can change the direction of torque rotation. Reducer has two roles, one is to change the direction of power transmission, and the second is to provide a **** the same transmission ratio for each gear. The following is the structure of the reducer classification:

1, cylindrical gear: simple structure, easy to process, commonly used helical cylindrical gear. Mostly used in the engine transverse when the main reducer, wheelside reduction or two-stage main reducer.

2, arc tooth bevel gear: transmission is characterized by the active gear axis and the axis of the slave gear perpendicular to each other at a point. Smooth operation, low noise, large bearing capacity. Applicable to the engine longitudinal occasions, the installation of high precision requirements.

3, hyperbolic gear: transmission is characterized by the active gear axis and the slave gear axis perpendicular to each other without intersecting.

4, worm gear: smooth and reliable, no noise, small size, light weight, can get a larger transmission ratio. Simple structure, easy to disassemble. Transmission efficiency is low, suitable for engine longitudinal occasions, but fewer applications.
