Abstract

The invention discloses a gearbox transmission inner shaft which comprises a shell, a transmission shaft is arranged in the shell, and a machining process of the gearbox transmission inner shaft comprises the following steps that blanks are screened and pretreated; rough machining is conducted on the blank to machine grinding samples of the ratchet wheel and the spline; carrying out heat treatment tempering on the blank; performing semi-finish machining on the blank, establishing a grinding reference, and roughly machining the ratchet wheel; performing copper plating protection on a non-carburizing part, and performing carburizing treatment on a ratchet wheel part; a finish machining reference is established, machining of the inner hole is completed, and a blank is obtained; performing secondary processing on the threads and the grooves on the blank to obtain a finished product; finished products are summarized and inspected, and oil seal packaging is performed after ultrasonic cleaning is performed. According to the method, protection and the sequence in the modification process are optimized, other machining operation is not affected while the modification purpose is achieved, in addition, in the machining process, the method is used as a reference datum, and the machining precision is practically and greatly improved.

Description

technical field [0001] The invention relates to the technical field of transmission shafts, in particular to a transmission inner shaft of a gearbox and a processing technology thereof. Background technique [0002] The gearbox has the characteristics of high speed and less support during operation, and its transmission inner shaft will bear a large force during operation. Therefore, in order to make it able to withstand this force, in the structural characteristics of the transmission inner shaft , its various parameters must meet the requirements, otherwise it may cause increased wear during operation due to its own parameter problems. [0003] And considering the load problem in its working process, in order to strengthen its surface properties in the preparation process, it often needs to be modified, such as cyanide, plating, etc. However, in the prior art, the irrationality of surface treatment often affects other subsequent processing operations, and in the process o...
