Loads in the Planetary-Pinion Gear with Modification of the Tooth Profile and Eccentricity of the Satellites

Abstract

In K-H-V planetary cycloidal drives, motion is transmitted to many rollers and teeth of the cycloidal disc. The number of factors affecting the load distribution in the engagement is very large, including modification of tooth profiles and inaccuracies in the manufacture of cycloidal gears. The forces arising from engagement load the satellite supports. The conducted research aims to more accurately account for the loads in the gear. It is based on an analytical solution to the problem of the effect of gaps in the engagement of the planetary gear and the eccentricity of the satellite on the load distribution in the engagement and the loading of the satellite support. A characteristic of the uneven load of the satellite support is proposed. The MathCad package was used in the computer experiment. It is shown that the operation of the cycloidal engagement is accompanied by a continuous change in the forces acting in the engagement.
