Tracking speed reducer

The utility model discloses a tracking speed reducer. The problem that the output torque cannot meet the torque requirement of a flat single shaft due to the fact that existing worm and gear transmission is low in efficiency is mainly solved. The device is characterized by further comprising a crankshaft (3) driven by a power source (9) to rotate, and the crankshaft drives the output pipe to rotate through a cycloidal gear transmission mechanism. According to the tracking speed reducer, output is achieved through a cycloidal gear transmission mechanism, the transmission efficiency is high (can reach more than 80%), the output torque is large, and the use requirement is met. 一种跟踪减速机。主要解决现在蜗轮蜗杆传动由于效率比较低，输出扭矩无法达到平单轴的扭矩要求的问题。其特征在于：还包括由动力源（9）带动转动的曲轴（3），所述曲轴通过摆线轮传动机构带动所述输出管转动。本实用新型提供一种跟踪减速机，采用摆线轮传动机构来实现输出，传动效率高（可达80%以上），输出扭矩大，满足使用需求。
