Study on the Calculating Method of Bending Stress for Non-Circular Gear
Profiles of non-circular gears and equivalent gears are compared in this paper, and profile differences are specifically investigated. Based on the cantilever beam theory, the calculating method of bending stress for non-circular gear is researched, and computational error by using equivalent gear instead of non-circular gear to calculate the bending stress is analyzed through the comparison of tooth form factors. Simultaneously, the numerical simulation of bending stress of non-circular gear is conducted on the basis of the FEM method. By the fitting curve comparison, the feasibility of using equivalent gear instead of non-circular gear to calculate the bending stress is testified.
