Bending fatigue test of spur gear teeth with 8 various tooth fillet made of normalized 0.45% carbon steel are carried out. It is shown that the maximum elastic stress along the tooth fillet is applicable as the rating stress of the fatigue strength in the case of the same rack. The Fe-3Si steel etching technique is used to detect plastic flow around the tooth fillet in fatigue test. And the cyclic stress-strain hysteresis loops at the tooth fillet of normalized gear teeth are measured by strain gage of 0.3 mm long. As the results, the linear cumulative damage rule of plastic strain amplitude and the proposed modified full wave method based on the plastic strain amplitude give good estimation for the varying load.
