The invention discloses a transmission system, a lifting variable-speed system and lifting equipment. The transmission system includes a power source shaft for connecting-in a power source, a load shaft for outputting power outwards to bear load, a moment limiter connecting the power source shaft and the load shaft for transmitting the output moment of the power source shaft to the load shaft within the set moment range, and a one-way locking mechanism connected to the load shaft and for one-way locking the load shaft to prevent the load from falling at the time of overload of the moment limiter. According to the embodiments, through the cooperation of the moment limiter and the one-way locking mechanism, when the moment limiter is overloaded, the load shaft is unidirectionally locked by the one-way locking mechanism, a heavy object is prevented from falling when the load is overload, the safety of the transmission system is improved, and the transmission system can be widely used in the lifting equipment.

    本发明公开了一种传动系统、起升变速系统及起升设备。其中,该传动系统包括:动力源轴,用于接入动力源;负载轴,用于向外输出动力,以承载负载;力矩限制器,连接所述动力源轴和所述负载轴,用于在设定的力矩范围内,将所述动力源轴的输出力矩传递至所述负载轴上;单向锁止机构,连接所述负载轴,用于在所述力矩限制器过载时单向锁止所述负载轴,以防止所述负载下落。本发明实施例通过力矩限制器与单向锁止机构的配合,在力矩限制器过载时,通过单向锁止机构单向锁止负载轴,可以避免负载过载时的重物下坠,提升了传动系统的安全性,可以广泛应用于起升设备上。
