がある。(i) Apply load to large gear 1. To apply the load, a friction piece (not shown) may be brought into sliding contact with the outer periphery of the large gear 1, or a small gear (not shown) other than the small gear 2 may be meshed with the large gear 1. There are various methods, such as braking the rotating shaft of the motor.
(ii) 小歯車２を回転駆動する。(ii) Drive the small gear 2 to rotate.
(iii) 大歯車１の中心軸Ｃ１と小歯車２の底面との

部が押しつぶされて除去される。(iii) The distance between the central axis C1 of the large gear 1 and the bottom surface of the small gear 2 is H, the distance between the central axis C2 of the small gear 2 and the bottom surface of the large gear 1 is G, and the distance between the central axes C1 and C2 is V. When the pinion 2 is moved, G is periodically varied by ΔG, H is periodically changed by ΔH, and the pinion 2 is moved in a plane perpendicular to the bottom surface of the large gear 1. (Indicated by arrow ΔS in Figure 1). Like this, large gear 1
If the relative position between the gears 1 and 2 is changed periodically, the tooth contact positions of both gears 1 and 2 will change periodically, and as a result, the convex portions of the entire tooth surfaces of both gears 1 and 2 are crushed. removed.
(iv) このようないわゆるすり合せに際しては両歯

ましい。さらに潤滑油に低粘度のものを使用す
ればすり合せ効果はさらに高まる。(iv) During such so-called grinding, the tooth surfaces of both gears 1 and 2 are heated by frictional heat, so it is desirable to supply low-viscosity lubricating oil to the tooth surfaces to cool them. Furthermore, if a low-viscosity lubricant is used, the rubbing effect will be further enhanced.

単純化される。 3 and 4 show a second embodiment of the present invention, in which the small gear 2 is not moved periodically, but the large gear 1 is moved periodically. In this case G is ΔG
, and H is periodically varied by ΔH.
V is periodically varied by ΔV. This embodiment also provides the same effects as the first embodiment. However, without moving the small gear 2 on the driving side, the large gear 1 on the driven side
, the apparatus for periodic movement is simplified.

This is a cross-sectional view. In this case, a load torque of 2.0 Kg-m is applied to the hypoid large gear 1 with an outer diameter of 190 mm, the small gear is driven at 500 rpm, and the periodic fluctuation in each direction is calculated for 30 seconds per cycle in total. The process took 2 minutes and 30 seconds. Similar results were obtained in the second example. As is clear from FIGS. 5 and 6, according to the method of the present invention, the surface roughness of the hypoid gear is significantly reduced.
