A Simulation Analysis of the Meshing Efficiency of a Spur Gear System Considering the Tooth Deformation

The meshing efficiency is a very important parameter for the gear system, which can greatly affect the system transmission performance. However, the unreasonable design parameters can reduce the meshing efficiency, especially for the meshing efficiency caused the gear elastic deformation. To overcome this problem, a meshing efficiency calculation method of a spur gear system with the gear elastic deformation is presented in this paper. The effects of the tooth number, transmission ratio, addendum coefficient, pressure angle, friction coefficient, center distance, tooth elastic deformation on the meshing efficiency are discussed. It seems that the meshing efficiency of the gear system can be affected by the operational conditions and gear geometric parameters. This works can provide some guidance for the improvement method of the power loss of the oil stirring of the spur gear systems.
