Basic Studies on Scoring of Spur Gears : 4th Report, Effect of Module on Scoring Resistance

抄録

The effect of module on scoring resistance of the Vau-Null gear pairs of the same gear ratio at the constant centre distance was examined from the point of view of the flash temperature. It was revealed from the calculated results of the flash temperature and the experimental results on scoring tests that the effect of module on scoring resistance is complicated. When the module of the gear pairs is comparatively small, the flash temperature is approximately proportional to module. Further, when the module is large, the effect of module on the flash temperature remarkably increases. Therefore, the scoring resistance will remarkably decrease. The above cited facts well coincide with the experimental results on scoring.
