Three dimensional finite element stress predictions of spur gears compared to gear fatigue rig measurements

Conference ·
OSTI ID:5425868
A three dimensional finite element analysis technique has been developed for evaluating the gear tooth contact and fillet bending stresses. The method is based on an isoparametric formulation using 20-noded solid elements and the sub-structure approach to minimize computer core usage. The analysis has been applied to a test case of LCR spur gears specifically designed for pitting endurance testing on a gear fatigue rig. The analysis results are compared with strain gauge results obtained from gear fatigue rig to determine allowables for gear tooth stressing. They are finally compared to the tooth stresses obtained using a gear teeth dynamic model for further substantiation.
