摘要
介绍了带自锁功能的手摇减速器的工作原理及设计计算要点。该减速器在普通手摇减速器的基础上,增加了一套自锁装置,同时运用了棘轮防逆转、螺纹自锁及摩擦片传动等各种手段,实现负载的手动上升、下降并实现上升或下降过程中,脱手后负载不坠落的安全功能。
The main working principle and design calculation of the hand with self-locking function of speed reducer is introduced.The reducer added a self-locking device, at the same time, the utility model has the advantages that the ratchet wheel is used for preventing the reversal, the thread self-locking and the friction plate transmission, etc., and it can realize the rise or fall in the process of load without falling off security features.
