Abstract

The invention relates to a three-dimensional modeling method for gear hobbing of helical cylindrical gears. By using computer-aided drawing software, a three-dimensional model of a gear blank and a three-dimensional model of a hob tooth blade track surface are established, and the gear hobbing process is simulated by setting processing parameters. The three-dimensional model of the single-tooth profile can be obtained through motion and difference drawing, and the main technical characteristics of the processed gear can be displayed for surface observation, roughness analysis, and performance analysis. Modeling solves the problem of high cost of experimental measurement of gear hobbing processing effect, and at the same time can further analyze the influence of various processing parameters on the performance of parts.

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, ...
