Axial fixing method for disc-like components mounting on axle

Abstract

The present invention relates to an axial fixing method for mounting disk-like part on the shaft. Said method includes the following steps: (a), machining step on the shaft to form shaft neck, on the column surface of said shaft neck machining ring groove whose section is made into trapezoidal form; (b), machining inner hole of disk-like part and making it and shaft neck of shaft form smaller clearance fit; (c), axially fixedly-connecting disk-like part and shaft neck of said shaft; and (d), using retention screw to fasten the disk-like part on said shaft.

Description

Technical field: [0001] The present invention relates to the method of axial fixing of disc parts for transmitting torque. Background technique: [0002] The disc parts (especially the disc parts that transmit torque) are installed on the shaft, and the reliable fixation in the axial and radial directions is an important condition to ensure the reliable operation of the parts. The parts are installed on the shaft, and the anti-rotation between the parts and the shaft is mostly fixed by keys; however, there are usually many ways to fix the parts axially on the shaft. [0003] Fig. 1 shows that after the disk part 3 is installed on the shaft 1 through the key 2, it is axially fixed and locked with two round nuts 11. In this method, the axial dimension of the component shaft 1 must be lengthened. At the same time, due to the change of the positive and negative rotation of the disc-type component and mechanical vibration, the two round nuts may loosen, making the axial fixation...

AI Technical Summary

Problems solved by technology

Although this fixing method is reliable and the axial dimension of the shaft journal of the shaft 1 is relatively short, the outer diameter of the disk parts is relatively large, and the diameter of the step 8 of the shaft 1 must also be relatively large, and the larger diameter, in a certain In some cases, it is difficult to realize

[0006] The above three methods all have certain shortcomings, which cannot solve the problem that the diameter of the shaft step for installing disc parts is small, the axial dimension of the journal is short, and the diameter of the disc parts is small. On the problem of reliable fixation in the axial direction
