Research on the method to calculate deformation of curve-face gear

Abstract

As a new type of face gear, the tooth deformation of curve-face gear has always been one of the research focuses. The conventional method of calculating the tooth deformation of face gear is widely focused on the basis of Buckingham's opinion, without considering the actual contact status. Therefore, in order to resolve this problem, a new calculation of curve-face gear tooth deformation is proposed. Firstly, the tooth distribution regularity of curve-face gear was analyzed. Then, a model for predicting the tooth elastic deformation of curve-face gear, taking into account the equivalent teeth, cross-section property, actual contact status and load distribution, was presented. Finally, the deformation variations were analyzed by taking into account the specific parameters such as eccentricity e, order number n1 and n2, and the correctness of the proposed mathematical model was verified by the results of the related experiment.
