Abstract
An analytical model of evaluating tooth pair deflection along the line of contact is proposed in this paper to preliminarily determine the load distribution between tooth pairs contacting instantaneously for crown spur gears. Further, a three-dimensional thermomechanical point contact method is introduced for modeling the normal approach of two contacting teeth. Combined with tooth and fillet-foundation deflections, a coupled thermoelastic mesh deformation model for crown gears is developed. The influence of load, angular velocity and friction coefficient on the normal approach of the contact, load sharing ratio and transmission error during meshing are respectively investigated. It is suggested that without considering thermal influence, the vibration excitation of gears can be underestimated. Considering the coupled thermoelastic deformation of meshing gears may result in a better evaluation of transmission error and facilitate the subsequent tooth modification design and dynamic study.
