Abstract
This paper presents a model for the analysis of transmission errors of helical gears under load. The model accommodates the modification of tooth surfaces, gear misalignments and the deformation of tooth surfaces caused by contact load. In this model, the gear contact load is assumed to be nonlinearly distributed along the direction of the relative principal curvature between the two contacting tooth surfaces. As compared with conventional tooth contact analysis (TCA) that assumes gear surfaces as rigid bodies, the model presented in this paper provides more realistic simulation results on the gear transmission errors and other gear meshing characteristics when the tooth surfaces are deformed under load. The proposed model is applied to a pair of helical gears in the numerical example included in the paper.
