Abstract

Using the ANSYS Parametric Design Language (APDL) to establish 3D entity of double-arced gear and forming a corresponding finite element model so as to carry out an analysis on the bending stress of gear. The influence law of gear's bending stress affected by nominal pressure angle and technological angle of tooth profile has been summarized and obtained a conclusion that the maximum bending stress before running-in period occurred at the waist place of the tooth, thus provided a theoretical foundation for the design and application of double arced gears.
