Abstract
Abstract. A novel transmission with multistage face gears as the core
component achieves variable speeds via differential gear shifting.
Single/multistage coupled vibration models have been established in this
study to derive the coupled vibration equation in order to accurately solve
the load distribution between the meshing teeth and the vibration shock
between the shifting stages in the transmission process, improve the
transmission smoothness of the face gears during the shifting processing,
suppress the resonance of face gears meshing, reduce the noise, and optimize
the power transmission performance. The characterization relationships of
the key parameters such as equivalent mass, rotational inertia, equivalent
mesh stiffness, support stiffness, and meshing damping coefficient to
dynamic characteristics were investigated. The linear and nonlinear dynamic
characteristics of coupled vibration differential equations were solved. The
influence rules of factors such as integrated transmission error, dynamic
load, tooth surface friction, loading speed, and load on the transmission
system were analyzed. The results of the study provide a theoretical basis
for the expansion of field of application of transmission devices.
