Optimal calculation and experimental study on cutting force of low-angle straight tooth face gear by power skiving

Low-angle straight tooth face gear transmission has significant advantages such as compact structure, small axial force, good shunt effect, and insensitivity to installation errors, demonstrating great superiority in the main reduction and torque distribution structure of helicopters. In this paper, the calculation of cutting force in the process of gear turning is studied, and the mathematical model of low-angle straight tooth face gear is established, and the numerical calculation and simulation analysis of cutting force are completed. On this basis, the gear machining test was completed on the gear machine, and the actual cutting force was collected, which verified the correctness of the cutting force calculation method and the feasibility of the cutting force optimization scheme, and provided a new solution for the cutting force calculation of the low-angle straight tooth face gear machining in industrial production.
