The Bulk Temperature Analysis of the Involute Spur Gear Based on Parameterized Modeling of APDL

Because of large amounts of heat generation, spur gear transmission of heavy load and high speed can not only have a serious effect on the temperature field of the whole transmission system, but also lead to thermal deformation, which can badly affect the working reliability and the lifetime. With the complex application of gear meshing, friction and thermal conduction, heat flux and heat transfer coefficient for the contact surface and the sides in different engagement position are analyzed precisely. The parameterized three-dimensional finite model of a single tooth segment is built up on the basis of APDL in ANSYS, and the steady temperature field of the tooth segment is obtained. The effect of different torques and speeds on the steady temperature field is also analyzed.
