The automobile differential is composed of differential housing, planetary gear shaft, two planetary gears, two half-shaft gears, composite thrust gasket, etc; The differential is a mechanism that can make the left and right or front and rear drive wheels turn at different speeds. The main function of the differential is to make the left and right wheels roll at different speeds when the car turns or runs on uneven roads, that is, to ensure that the drive wheels on both sides have pure rolling motion.

Generally, dynamic balancing is required in the following cases of automobile differential:
1. When starting or accelerating or decelerating, you can feel obvious jerk impact and hear abnormal noise;
2. It is difficult for the vehicle to turn around when turning a corner, and the resistance is very high, and the tires are severely worn;
3. If the transmission differential of the vehicle is damaged, the wheels can only be turned by sliding when the vehicle is turning.

The function of the transmission differential is to transmit the power of the transmission to the left and right wheels, and to make the left and right wheels have different rotational speeds when turning. When these problems begin to appear in cars, there are ways to solve them. The differential case dynamic balancing machine developed by Hangzhou Jizhi is a dynamic balancing correction equipment specially designed for automobile brake discs and differentials. It can not only automatically measure the unbalance value of the workpiece, but also automatically drill and print the code.
