Abstract

A numerally controlled tooth grinding method for cycloid gear features that an abrasive disk is driven by a cranker-connecting rod mechanism to linearly reciprocate for forming an equivalent cylindrical grinding surface and the cycloid gear to be machined is driven by a dual-coordinate numerally controlling system controlled by microcomputer to shift and rotate, so enveloping whole tooth profile of cycloid gear.

Description

technical field

[0001] The invention belongs to the gear manufacturing subordinate to the field of mechanical manufacturing. Background technique

[0002] Cycloid gear reducer has the advantages of large reduction ratio and simple structure, and has been widely used. The key part of cycloid reducer is cycloid gear, which needs quenching and grinding. For many years, cycloidal gear grinding machines have used the disc grinding method that simulates the rotation and revolution of the gears of the cycloid reducer. This method has low productivity, thus increasing the cost of the cycloid gear reducer. This limits the wide application of the cycloid gear reducer. In 1988, the inventors of the present invention successfully developed a method for grinding cycloid gears with abrasive belts. Since the abrasive belts cannot achieve high precision, only the problem of rough grinding of cycloid gears is solved. SUMMARY OF THE INVENTION
