Zusammenfassung: | The present invention is intended to smoothly supply a lubricant around a case pin in a cycloidal reducer. According to the present invention, lubricant storage grooves (43) are formed in the vertical direction on the inner surfaces of pin grooves (42A) that are continuously formed on the inner surface of a ring gear housing (10). A preload adjustment ring (50) is screwed into a shaft through hole (18A) of a hold flange (18) through which a crankshaft (28) of the cycloidal reducer passes, and moves up and down by rotation, wherein the preload adjustment ring (50) is configured such that the preload with an inner ring (76) can be accurately adjusted by pressing an outer ring (72) of an upper taper bearing (Bu), the inner ring (76) and the outer ring (72) having a roller (74) interposed therebetween.
La présente invention vise à délivrer sans à-coups un lubrifiant autour d'une broche de boîtier dans un réducteur cycloïdal. À cet effet, selon la présente invention, des rainures de stockage de lubrifiant (43) sont formées dans la direction verticale sur les surfaces internes de rainures de broche (42A) qui sont formées de façon continue sur la surface interne d'un boîtier d'engrenage annulaire (10). Une bague d'ajustement de précharge (50) est vissée dans un trou traversant d'arbre (18A) d'une bride de maintien (18) à travers laquelle passe un vilebrequin (28) du réducteur cycloïdal, et se déplace vers le haut et vers le bas par rotation, la bague d'ajustement de précharge (50) étant configurée de telle sorte que la précharge avec une bague interne (76) peut être ajustée avec précision par pression d'une bague externe (72) d'un palier conique supérieur (Bu), la bague interne (76) et la bague externe (72) ayant un rouleau (74) interposé entre celles-ci.
본 발명은 싸이클로이드형 감속기에서, 케이스핀 주위로 윤활유를 원활하게 공급하고자 한다. 본 발명에 의하면 링기어하우징(10)의 내측면에 연속적으로 성형되어 있는 핀홈(42A)의 내측면에 저유홈(43)을 상하 방향으로 성형하고 있다. 그리고 싸이클로이드형 감속기의 크랭크 샤프트(28)가 관통하는 홀드플랜지(18)의 샤프트 관통공(18A)에 나사 결합되어 회전에 의하여 상하 이동하는 예압조절링(50)이, 상부 테이퍼 베어링(Bu)의 외륜(72)을 가압함으로써 롤러(74)를 개재하고 있는 내륜(76)과의 예압을 정확하게 조절할 수 있도록 구성하고 있다. |
