Abstract
In this study, carburized gears of m=1.0-1.5 with various effective case depths are put to bending fatigue tests, and the fatigue strength is obtained. The test results verify that the effective case depth recommended in the AGMA standard is appropriate for the enhancement of bending strength. 0n the basis of results, S-N curves are determined and illustrated. The fatigue strength of the gears is about 1100 MPa. The fatigue strength is compared and illustrated with the strength of the gear teeth of m=5, and the effect of the tooth size on the fatigue strength is estimated quantitatively. The estimated size factor of the carburized gears is 1.0-1.3.
