  • Flash temperature analysis method for polymer gears with consideration of deviations in meshing kinematics [Elektronski vir]
    Černe, Borut, 1989- ...
    The presented work describes a computational method for carrying out a detailed and thorough examination of the flash temperature rise (i.e. the local "instantaneous" temperature increase on a ... contact interface, due to frictional effects) present on the tooth flanks of a polymer gear pair, composed of a combination of POM and PA66 thermoplastics, during a given meshing cycle. The method involves a decoupled sequential procedure, where first the mechanical response of the gear teeth during a whole meshing cycle is analyzed using finite element analysis and, subsequently, a semi-analytical thermal analysis procedure is employed, with which the local flash temperature rise under a given tooth-pair contact can be evaluated. The method provides an accurate reproduction of the actual thermo-mechanical processes taking place at the gear teeth contact interfaces and allows for an investigation of the influence of deviations in the gear flank geometry and gear tolerances, while retaining a manageable enough form for application with moderate computational resources.
