附图所示的双速行星齿轮装置,可用作传动机构或进给机构。内装齿轮的壳体A起着驱动皮带轮的作用,其内孔中装入磷青铜轴衬B,B与固定法兰套C成良好的转动配合。通过法兰套台肩端面和拼帽D将皮带轮轴向定位。拼帽D拧在长套E的螺纹端上,E的凸缘可防止其轴向走动,在凸缘端还带有淬硬的离合器牙齿。长套装在两个磷青铜轴衬F和G中,并与它们成良好的转动配合,38齿的中心齿轮H借键装在长套的右端,并用埋头螺钉锁紧。长套E还装有另外两个磷青铜轴衬J和K。输出轴L就装在J和K内,与它们成良好的转动配合。通过轴肩和拼帽M将输出轴L轴向定位。
The two-speed planetary gear arrangement shown in the drawings can be used as a transmission or feed mechanism. A gear housing A plays the role of a drive pulley, the inner hole is filled with phosphor bronze bushings B, B and a fixed flange C into a good rotational fit. Place the pulley in the axial direction through the shoulder of the flange and the headgear D. The cap D is screwed onto the threaded end of the long sleeve E, the flange of the E prevents its axial movement and also the hardened clutch teeth on the flanged end. Long set in the two phosphor bronze bushings F and G, and a good rotational fit with them, 38-pin central gear H by key installed in the right end of the long sleeve, and with countersunk head screw locking. Long sleeve E is also equipped with two other phosphor bronze bushings J and K. Output shaft L is installed in J and K, with them into a good rotation with. The output shaft L is axially positioned by the shoulder and head M.
