Abstract
With the increasing requirements of helical gears for high strength and low noise, it is significant to improve the accuracy of the load distribution ratio depending on the minimum elastic potential energy (MEPE) model. In this paper, an improved distribution model is developed to replace the theoretical contact ratio with the actual contact ratio and introduce the potential energy of the fillet foundation for comparison. Then, the operation process of the helical gear is divided into seven cases. Finally, combined with the finite element method, the accuracy of the improved model is confirmed. Results indicate that the load distribution model with fillet foundation energy is only effective under the front or the full tooth meshing. When the gear meshing includes the rear part of a tooth, the inclusion of the actual contact ratio and fillet foundation energy should be considered.
