- 論文の詳細を見る
The surface durability of tufftrided spur gears with a smaller number of teeth was investigated by carrying out a running test and compared with the case of the normalized steel spur gears. The surface durability of the tufftrided gear is found to be higher by 50.% than that of the normalized steel gear and a failure of the follower is hard to occur due to the effect of the residual compressive stress produced by tufftriding. The contact fatigue limit load (circumferential load) of the gear pair can be raised to a considerable extent by setting an operating pitch point in the range of double tooth pairs contact. Furthermore the range of applications of these experimental results was examined on the basis of the calculated results of Hertz stress and specific sliding.
