Problems solved by technology

For many years, cycloidal gear grinding machines have adopted the disc-shaped grinding wheel grinding method that simulates the rotation and revolution of the gears of the cycloidal reducer. The productivity of this method is very low, which increases the cost of the cycloidal gear reducer. However, the wide application of cycloidal gear reducer is limited.
In 1988, the inventor of the present invention successfully developed the cycloidal gear abrasive belt grinding method. Since the abrasive belt could not achieve high precision, only the rough grinding problem of the cycloidal gear was solved.

Embodiment Construction

[0014] The method and the device will be further described below with reference to the accompanying drawings.

[0015] Figure 1 and figure 2 For the general layout of grinding epicycloid gears, the cycloid gear rotates around the vertical axis O, and the fixed axis rotates at a slow speed; its rotation angle is represented by θ, and at the same time, the cycloid gear axis O moves along the X coordinate, and its movement amount is ρ means; the axis O of the disc grinding wheel 2 Horizontal arrangement, the periphery of the disc-shaped grinding wheel is repaired by an arc grinding wheel dresser, and its busbar is trimmed into an arc with a radius of r; the grinding wheel rotates B for high-speed grinding; at the same time, the grinding wheel is also in the vertical direction. , the equivalent shape of the grinding wheel in the working area is cylindrical. When the cycloid gear moves (ρ, θ), its outer surface will be surrounded by the cylindrical surface of the grinding wheel t...

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 [0003] The purpose of the present invention ...
