The invention discloses a split type fixed pulley device, and belongs to the technical field of mechanical design. Which comprises a fixed pulley, a split shaft, a cover plate and a gear set and is characterized in that three positioning holes are formed in one side of the split shaft, threads are formed in a shaft hole so that the shaft can be fixed, two pulley grooves with different diameters are formed in the other side of the shaft, meanwhile, three pulley grooves with different diameters are formed in one side of the fixed pulley, and anti-disengaging grooves are formed in the grooves. The phenomenon that the rope falls off in the rotating process is avoided, and the rope is wound on the fixed pulley and the split shaft; a positioning gear, an inner hexagonal gear, a driven duplicate gear, a driving duplicate gear and a driven gear are arranged below the cover plate, and all the gears are connected in sequence. Multiple transmission ratio schemes can be provided for the fixed pulley at the same time, the split shafts are detachable, one-wheel multi-shaft or one-shaft multi-wheel can be achieved, the workpiece cost is reduced, and meanwhile the efficiency is improved.

    本发明公开了一种分体式定滑轮装置,属于机械设计技术领域。包括定滑轮、分体轴、盖板和齿轮组,其特点是:分体轴的一侧开设有三个定位孔,轴孔内开设螺纹,以便使轴固定不动,轴的另一侧有直径大小不一的两个滑轮槽,同时定滑轮一侧也有直径大小不一的三个滑轮槽,槽上都设有防脱槽,避免转动过程中出现绳脱落的现象,绳索分别缠绕在定滑轮、分体轴上;盖板下方有,定位齿轮、内六角齿轮、从动二联齿轮、主动二联齿轮以及被动齿轮,各个齿轮依次连接。本发明可同时给定滑轮提供多个传动比方案,且分体轴是可以拆卸的,可以实现一轮多轴或一轴多轮,工件成本降低的同时,效率也提高了。
