Abstract

The invention discloses an involute gear-shaving cutter and belongs to the technical field of wheel gears. The involute gear-shaving cutter is characterized in that base cylinders with different diameters are used for generating tooth profile curved surfaces with a respective reference circle pressure angle alpha nc and alpha nd on the two sides of a tooth profile of the nvolute gear-shaving cutter, and the alpha nc is greater than the alpha nd. The gear-shaving cutter is specially designed for an asymmetric involute gear with double pressure angles and can be used for solving the problem that the existing gear-shaving cutter cannot process the asymmetric involute gear with double pressure angles. The tooth profile of the novel gear-shaving cutter mainly comprises a tooth crest 1, a left side tooth surface 2 generated by a first base cylinder 3 and a right side tooth surface 5 generated by a second base cylinder 4. Compared with the existing involute gear-shaving cutter, the involute gear-shaving cutter provided by the invention can carry out finish machining on the asymmetric involute gear with double pressure angles conveniently, rapidly and efficiently, thus the being wide in market prospect and having huge social and economical benefits.

Description

technical field [0001] The invention discloses an involute gear shaving cutter, which belongs to the technical field of gears. Background technique [0002] Due to the advantages of high power, high efficiency and long life, gear transmission has become the most important and widely used mechanical transmission device. With the rapid development of modern high-tech, gear technology has also made great progress. Especially in recent years, in order to conform to the development trend of modern mass production, gear transmission is developing towards high speed, heavy load, low noise, small size, energy saving, high efficiency, long life and low cost. [0003] The tooth shape not only affects the kinematic characteristics of the gear pair, but also affects the dynamic characteristics of the gear pair. The research shows that increasing the pressure angle can improve the fatigue strength of gear dedendum. However, if the pressure angle on both sides of the tooth is increased...
