FEM in Numerical Analysis of Stress and Displacement Distributions in Planetary Wheel of Cycloidal Gear

Abstract

Implementation of high speed engines requires application of high ratio mechanical gears. Relatively, the smallest mechanical gear is the cycloidal planetary gear known as Cyclo gear [2, 8- 11]. The complex construction of planet wheels in cycloidal planetary gear (Cyclo) practically makes impossible its optimal design. To calculate distribution of displacements and stresses in planet wheels with co- operating elements FEM has been implemented. There were series of numerical models of planet wheels generated and for example of real model of gear it has been calculated proper values of forces, strains and stresses. In the paper forces and strains calculated with FEM have been used to check the assumptions which have been applied only in analytical so far.KeywordsReaction ForcePlanetary GearDisplacement DistributionInside EdgeRadial ClearanceThese keywords were added by machine and not by the authors.
