摘要:
기어전동장치에서는, 캐리어가베어링을개재하여케이스에지지되어있다. 베어링은, 이너레이스와, 아우터레이스와, 복수의롤러와, 리테이너를구비하고있다. 롤러의회전축은, 베어링중심축에대해기울어져있다. 리테이너는, 인접하는롤러의간격을유지한다. 기어전동장치에서는, 이너레이스의외주면및 아우터레이스의내주면에, 롤러가회전축방향으로이동하는것을규제하는리브가설치되어있지않다. 또한, 케이스와캐리어중 어느한쪽에, 리테이너의대직경측의단부를수용하는홈이형성되어있다.
摘要(英):
In a gear transmission, a carrier is supported by a case via a bearing. The bearing is provided with an inner race, an outer race, a plurality of rollers, and a retainer. The rotational axis of the roller is inclined with respect to the bearing central axis. The retainer keeps the gap between adjacent rollers. In the gear transmission, ribs are not provided on the outer circumferential surface of the inner race and the inner circumferential surface of the outer race to restrict movement of the roller in the rotational axis direction. Further, a groove for accommodating an end portion of the retainer on the large-diameter side is formed in either of the case and the carrier.
