本文介绍一种不用离合器而采用轴线摆动的蜗杆及齿轮组合而成的离合传动机构、它本身既是传动机构,又是离合机构,具有结构简单,操作方便之优点。宜用于位置受限制,离合频繁、不便采用离合器的场所。本文同时还介绍了设计此种机构时,摆动轴线偏心应放置的方位及偏心量e与齿轮模数、蜗杆模教及齿轮中心距间的关系,以保证接合时不会产生碰撞冲击。 This paper introduces a clutch without the use of the axis of oscillation of the worm and gear combination of the clutch transmission mechanism, which itself is both the transmission mechanism, but also the clutch mechanism has the advantages of simple structure, easy operation. Appropriate for the location is limited, clutch frequent, inconvenient to use the clutch place. This article also describes the design of such institutions, the eccentric axis of the swing axis should be placed in the position and eccentricity e and gear modulus, worm gear and gear center distance to ensure that the collision will not produce impact.
