Bevel gear tooth crest processing method and bevel gear tooth crest chamfering machine

Abstract

The invention discloses a bevel gear tooth crest processing method and a bevel gear tooth crest chamfering machine, wherein in the method, the edges at the two sides of the bevel gear tooth socket or the edges at the two sides of the tooth crest are chamfered on the bevel gear tooth crest chamfering machine at the same time. The novel bevel gear tooth crest chamfering machine comprises a horizontal axis C (X), a vertical axis B (Z), a rotary axis A and a grinding carriage rotary axis D, which is a four-axis linkage numerical control chamfering machine. The invention also discloses a calculation method of a grinding wheel chamfering movement trace. The novel bevel gear tooth crest chamfering machine is a four-axis linkage full numerical control machine, and has the advantages of high automation level, easy operation and easier guarantee on product quality.

Description

technical field [0001] The invention belongs to the technical field of bevel gear processing, in particular to a bevel gear addendum chamfering method and a bevel gear addendum chamfering machine applying the method. Background technique [0002] With the development of science and technology, bevel gear tooth top chamfering also needs to be completed by mechanical automatic chamfering machines. It can improve the transmission performance of the bevel gear pair, reduce the collision between the tooth top and the tooth surface, stress concentration, vibration and noise during the transmission process. Bevel gear addendum chamfering has always been done manually, which is not only inefficient but also of uneven quality. Since the angle grinder is used in the chamfering process, a large amount of dust will be generated, which seriously endangers the physical and mental health of workers. At present, the trajectory of the grinding wheel of the mechanical bevel gear addendum ch...

AI Technical Summary

Problems solved by technology

Since the calculation of the grinding wheel trajectory is based on the theoretical tooth tip edge model, the error caused by the heat treatment deformation of the gear teeth cannot be avoided

Furthermore, the existing mechanical bevel gear addendum chamfering machine can only perform single-side chamfering of the addendum at one time, and the production efficiency is relatively low

At the same time, it is also difficult to realize the chamfering of the tooth top of the driving gear with a large helix angle.
