Year: 2025

Type: article

Abstract: To improve the load-bearing capacity of non-circular gear, a design method with asymmetric pressure angles was constructed. The method for forming tooth profiles of non-circular gear based on a rack with asymmetric pressure angles was studied, the enveloping motion model of the profile-forming process and the mathematical model for extracting the profile-forming points were analyzed. The correctness of the profile design by using the motion simulation method and the enhancement of tooth root bending strength were verified. To analyze the undercutting phenomena for non-circular gear, a graphical method for identifying undercutting in each tooth profiles of non-circular gear was designed. Finally, a design case with asymmetric pressure angles was used in the high-pressure constant-flux pumps, and the results show that the bearing capacity of the gear pair was significantly improved, and the tooth fracture phenomenon was eliminated.
