Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a turning machine for high and low gear synchronizer shafts. Background Art

[0002] The gearbox is composed of gears and shafts. It produces speed and torque changes through different gear combinations. Its main functions are: 1. Change the transmission ratio; 2. Allow the car to drive backwards without changing the direction of engine rotation; 3. Use neutral gear to interrupt power transmission so that the engine can start and idle, and facilitate gear shifting or power output. The function of the gearbox synchronizer shaft is: when shifting gears, the speed of the gear at the power output end is faster than the gear that is about to be shifted into this gear. This mechanical device solves the problem of inconsistent engine speed and gearbox speed during the gear shifting operation of the car, which can effectively avoid the inability to engage the gear and eliminate the gear noise during the gear shifting.

[0003] During the processing of the synchronizer shaft, it needs to be turned over. The traditional method is to use a gantry crane to turn it over.
