Configuration Design and Dynamic Analysis of Face Gear Axle Assemblies

A novel design scheme was put forward for full face gear axle, taking the excellent characteristics of face gear drive, such as simple structure, low noise, low sensitive to installation errors and high interchangeability and so on. Firstly, the working principle and characteristics were analyzed. Secondly, based on face gear forming principle and structural conditions, a 3D model and virtual prototype for face gear axle were built. Then the kinematics and dynamics simulation were carried out with ADAMS/View2013 software for the face gear drive in straight driving condition and turning driving condition to analyze the torque and angular velocity. Finally, the machining test of face gear was carried out and face gear test bench was set up. Meanwhile, the differential performance experiments of axle were completed. The simulation results are consistent well with the experimental results, demonstrating the validity of the design scheme. These contributions would improve engineering applications of face gear axle.
