Stress Analysis of Plastic Spur Gear Using White Ellipse Polarization Method

Abstract

The evaluation of time dependent stresses in plastic spur gear tooth is important from the viewpoint of needs for producing high-precision and-strength gears. Few expreimental studies on stress analysis of plastic gear tooth have been reported. In this study, the authors attempt to measure and trace stress variation around gear tooth under engagement using the technique of white light photoelasticity with elliptical polarization. As the results, the experimental technique adopted is very useful for measurements of complex phenomena which is varying with time.
