Abstract

Gear strength analysis is important to gear drive design, and its calculating accuracy is mainly decided by gear model. Several factors influencing the spur gear model building accuracy by finite element method (FEM) are presented, including geometric model and boundary, loading position and load types. The research includes: (1)A geometric model of spur gear is built. (2)Based on the gear model, geometric boundary of analytic model is determined. (3) The loading point of bending strength calculation is studied. (4)Static effective load and dynamic contact load effects on root stresses and tooth deformation are researched. The results show that tooth profile, geometric boundary, loading position and effective load, are the key factors of calculating accuracy and gear strength analysis. The reasonable FEM modeling methods can improve the calculating precision.
