Technical Field

[0001] The utility model relates to the technical field of differential case processing, in particular to a special processing tool for a differential case shaft hole. Background Art

[0002] The car differential is a mechanism that enables the drive wheels to rotate at different speeds. It is mainly composed of left and right half-shaft gears, two planetary gears and a gear rack. The differential is installed to adjust the speed difference between the left and right wheels. In order to make the rotation speed of the car basically consistent when driving in curves, an intermediate differential needs to be added to adjust the speed difference between the front and rear wheels.

During machining, the housing is prone to displacement, resulting in machining errors and reduced product quality. Utility Model Content
