Abstract

The invention relates to a three-dimensional modeling method for a gear hobbing processing tooth surface of a helical gear. A three-dimensional model of a gear blank and a three-dimensional model of the hobbing cutter blade trajectory surface are established in computer-aided drawing software; the gear hobbing processing motion is simulated through setting of processing technology parameter; a single-tooth profile three-dimensional model is obtained by differential drawing; the main technical features of the processed gear can be displayed, so as to carry out the operations of surface observation, roughness analysis, performance analysis, and the like; and three-dimensional modeling of the gear hobbing processing tooth surface of the helical gear is realized, which solves the problem of high cost of experimental measurement of gear hobbing processing effect, and can further analyze the influence of various processing parameters on component properties.

Description

technical field [0001] The invention belongs to the technical field of computer-aided processing, and in particular relates to a three-dimensional modeling method for hobbing a tooth surface of a helical cylindrical gear. Background technique [0002] The existing gear machining generally uses the gear hobbing machining method, and its final machining effect and part performance can only be verified experimentally, and it is impossible to directly simulate and analyze the part performance and observe the machining effect. [0003] For example, in the determination of the surface roughness of helical cylindrical gears, the existing technology can only measure the surface roughness of helical cylindrical gear hobbing by using the experimental method after the samples are actually processed, but the cost of the experiment is high. And it is difficult to reflect the direct relationship between the surface roughness and the main influencing factors such as processing parameters, ...
