The invention discloses a composite speed reducer. The speed reducer comprises a case, a case cover, a worm, worm gear and an output shaft, wherein the case and the case cover are covered with each other; the worm and the worm gear are installed in the case and meshed with each other, a driving shaft is inserted and fixed in the center of the worm gear, a crank synchronously rotating with the worm gear is fixed to the driving shaft in a sleeving manner, and a small shaft parallel to the driving shaft is arranged at the end of the crank in a protruding manner; the output shaft is arranged in the case and is parallel to the driving shaft, a rocking bar which synchronously rotates is fixedly mounted on the output shaft in a sleeving manner, a waist groove is formed in a bar body of the rocking bar, and the small shaft is arranged in the waist groove and can relatively slide; and the distance A between the center line of the small shaft and the center line of the driving shaft, the distance B between the center line of the small shaft and the center line of the output shaft when the small shaft slides to the maximum amplitude state in the waist groove and the distance C between the center line of the driving shaft and the center line of the output shaft meet the relation that A2+B2 = C2. When the crank drives the rocking bar to form a positive 90-degree included angle, the self-locking of the output shaft is realized; and the speed operation curves of the crank and the rocking bar are symmetrically and normally distributed, so that the operation shaking of a brake bar can be reduced.
本发明公开了一种复合型减速机，包括：相互盖合的机箱和箱盖；装入机箱内相互啮合的蜗杆和蜗轮，蜗轮的中心插固有主动轴，主动轴上套固有与蜗轮同步旋转的曲柄，所述曲柄的端部凸出设置有与主动轴相互平行的小轴；以及装入机箱内与主动轴相互平行的输出轴，输出轴上套固有同步旋转的摇杆，摇杆的杆体上开设有腰槽，小轴装入腰槽内且可相对滑动；小轴中心线与主动轴中心线的距离A、小轴在腰槽内滑动至最大幅度状态时小轴中心线与输出轴中心线的距离B以及主动轴中心线与输出轴中心线的距离C，三者关系：A2+B2＝C2。当曲柄带动摇杆呈正90度夹角，实现输出轴自锁；且曲柄和摇杆速度运行曲线呈对称和正态分布，能降低闸杆运行抖动。
