Abstract

The invention discloses a cycloidal gear modeling method. The method comprises the steps of 1, setting the basic parameters of a cycloidal gear; 2, establishing a profile equation of the cycloidal gear; 3, generating a cycloidal gear profile curve according to the basis parameters obtained in step 1 and the profile equation obtained in step 2; 4, generating a cycloidal gear entity from the profile curve obtained in step 3 by means of a stretching projection command. The method can effectively solve the problems of low efficiency and poor precision of cycloidal gear modeling.

Description

technical field [0001] The invention belongs to the technical field of gear modeling, and in particular relates to a cycloidal gear modeling method. Background technique [0002] Cycloidal pinwheel reducers are widely used in mining, metallurgy, transportation, robotics and other fields because of their advantages such as light weight, large transmission ratio, high efficiency, stable operation and long life. However, the related theory of cycloidal gear, the key component of cycloidal pin gear reducer, lacks systematic and detailed derivation, which seriously restricts scholars from doing more in-depth research on cycloidal gear. [0003] With the rapid development of CNC machine tools, its application in the field of cycloidal gear processing is becoming more and more common, and the three-dimensional modeling of cycloidal gears is the primary problem to be solved in its NC machining programming. The current modeling methods are mainly programming calculations or secondar...
