The invention relates to the field of portal crane swing equipment, in particular to a portal crane swing mechanism driving system which comprises a motor. And the motor is connected with the speed reducer through a torque-limiting permanent magnet coupling. According to the invention, a limit torque limiter is replaced by the torque-limiting permanent magnet coupling; the whole driving system ismore sensitive in protection action, meanwhile, automatic recovery can be achieved, damage to parts is reduced or avoided, meanwhile, a novel torque limiting type permanent magnet coupler is adopted,the driving system can have the soft start function, and the stability of the whole system is better guaranteed.

    本发明涉及门机回转设备领域,具体来说是一种门机回转机构驱动系统,包括电机;所述电机通过限矩型永磁联轴器与减速机相连接。本发明公开了一种门机回转机构驱动系统,本发明采用了限矩型永磁联轴器替代了极限力矩限制器,使得整个驱动系统保护动作更为灵敏,同时能够自动恢复,减少或者避免了零件的损坏,同时同采用新型的限矩型永磁联轴器,可以使得驱动系统具有软启动功能,更好的保证了整个系统的稳定性。
