The dynamic strain distribution in gear teeth during operation was studied by the photo-elasticity technique. A gears has been one of principal machine elements, and it sometimes causes serious problems on noise and vibration at meshing point during operation. In order to understand the mechanism at the meshing point, it is important to know the strain distribution in gear teeth in dynamic state. In this experiment, the gears were made of transparent epoxy resin, and photo-elasticity technique was applied for visualization of strain distribution around meshing area of gears, and the fringe patterns caused by strain distribution were recorded by a high-speed camera. As a result, the effect of slipping contact and grease became apparent from the strain distribution.
