Abstract

The characteristics and the tooth distribution regularity of curve–face gear were analyzed based on the elastohydrodynamic lubrication. Then a model for the prediction of mechanical dynamic efficiency of curve–face gear was presented by the concentrated parameters, including dynamic-loading tooth force, coefficient, the oil film thickness, the space relative velocity and load distribution. The discretization method was introduced to solve the computational formulas of key factors above. A meshing period defined from trough (enter meshing point) to peak (outer meshing point) of the pitch curve and the tooth profile was discreted into some parts for calculation of the sliding and the rolling power losses. The dynamic and static efficiency of curve–face gear were analyzed, and the results of simulation and test were similar during the corresponding time, which verified the correctness of theoretical model.
