Abstract

A cycloidal gear strength calculation method relates to the technical field of cycloidal gear processing, and comprises the following steps: step 1, deriving a parameter calculation process of the basic size of a cycloidal gear; step 2, explaining a calculation method of the torque under the allowable surface load and the allowable surface pressure of the cycloidal gear according to the content inthe step 1; step 3, explaining the cycloidal gear design life evaluation process according to the content of the step 2, wherein the process comprises the allowable torque under the expected life, the service life under the allowable torque and the service life under the actual use torque; and step 4, listing strength calculation results of the cycloidal gear transmission mechanism. According tothe cycloidal gear strength calculation method, under the condition that the load and the service life meet the design requirements, the calculation process is simplified according to the conservativecalculation principle, and the cycloidal gear strength calculation efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cycloidal gear processing, in particular to a method for calculating the strength of cycloidal gears. Background technique [0002] K-H-V cycloidal pin wheel planetary transmission is widely used in industrial robot reducers. It has the advantages of large reduction ratio, high transmission efficiency, high transmission accuracy, small backlash, stable load and reliable operation. [0003] Cycloidal gear is an important part of K-H-V cycloidal pin wheel planetary transmission, and its strength has a crucial influence on the overall working state of the transmission. In the actual working process, when the cycloidal gear and the tooth surface of the pin tooth mesh, their contact and force are more complicated. The surface of the cycloidal gear is prone to fatigue pitting and gluing, which will affect the transmission accuracy and change the meshing state. Therefore, the development It is very necessary to...
