Description

technical field [0001] The invention relates to the field of auto parts production, in particular to a production method and production equipment for an automobile transmission gear. Background technique [0002] The gearbox is one of the main components of the automobile transmission system. The gearbox gear is a very important part of the gearbox. The commonly used material for the gearbox gear is forged steel. Working under alternating conditions, the transmission gear relies on its own structural size and material strength to bear the external load, which requires the material to have high strength, toughness and wear resistance. Although the existing manufacturing method of the transmission gear is simple, However, the quality of the obtained product is not high, the service life is not long, and the machining accuracy of the gear is low, and the surface roughness cannot meet the requirements; in the production process of the transmission gear, it is necessary to use a ...
