Abstract

The invention discloses a method for hobbing a disc cylindrical gear type spiral involute gear. The disc cylindrical gear type spiral involute gear can be directly hobbed by adjusting the parameters of a general hobbing cutter on a numerical control hobbing machine or a modified common hobbing machine to make the parameters accord with relationships shown in the specifications. The method has the advantages of simple process, high processing efficiency and low cost.

Description

technical field The invention relates to a processing method of mechanical parts, in particular to a method for generating and processing gears with a new type of tooth profile that can be used for intersecting shaft transmission and meshing speed gears, in particular to a dish-shaped cylindrical gear type spiral progressive Hobbing method of open wire gear. Background technique As we all know, the principle of speed uniformity of involute gear transmission is based on the fact that the speed of the meshing point moving along the common normal of the involute is uniform on the common normal (usually 20° pressure angle). This is no problem for parallel shaft spur gear drives. For bevel gear transmission with intersecting shafts, only spherical involute can satisfy the principle of uniformity of involute gear transmission speed. But the processing quality of the spherical involute is difficult to guarantee, so the uniformity of the transmission speed is poor, and the transmi...
