Study on the Instantaneous Temperature and Life Prediction of Polymer Gear Based on ANSYS/LS-DYNA

Abstract

T aking the polymer gear as the research object , analyzing the instantaneous temperature rise of the tooth surface in the polymer gear t hrough combined systematical approach of theoretical arithmetic and finite element analysi s . It is found that the loading torque , c o mpared to the rotational speed , has a more significant effect on the instantaneous temperature rise . Take the influence of the speed and the loading torque of the meshing polymer gear into full consideration , the life of the gear can be predicted. And its correctness also can be verified by experiments, w hich is of great theoretical value a nd has a promising prospect on engineering application.
