Abstract

A method for machining an input shaft of a main reducing gear of a heavy load automobile is characterized by comprising the following steps of (1) blanking and forging, (2) rough turning, (3) surface treatment, (4) finish turning, (5) hobbing, (6) deep hole drilling, (7) radial hole drilling, (8) plane milling, (9) quenching treatment, (10) external grinding, (11) steel ball pressing, and (12) cleaning, oil applying, rust preventing and being putting in storage. Through the method, machining is convenient, product quality and production efficiency are improved, the service life is prolonged, and potential safety risks are avoided.

Description

technical field [0001] The invention relates to a processing method for auto parts, in particular to a processing method for an input shaft of a main reducer of a heavy-duty vehicle. Background technique [0002] The input shaft of the final drive is an important connection for the front engine rear wheel drive (or all-wheel drive) in a heavy-duty vehicle product. During the movement of the car, the input shaft of the final drive and the output of the transmission (or transfer case) Power transmission between shafts plays a very important role in the transmission system. Once the part fails, the transmission will be inaccurate, which will endanger safe driving. The existing processing method has low processing precision, low production efficiency and short service life. Contents of the invention [0003] The purpose of the present invention is to provide a processing method for the input shaft of the main reducer of a heavy-duty vehicle that is convenient for processing,...
