目前国内各种联轴器对于锥形转子制动电机均不尽适用,这是因为锥形转子制动电机使用的联轴器不仅要传递扭矩,而且电机启动时轴向伸出,制动时轴向缩回,联轴器需要轴向移动灵活,起重行业用的锥形电机,载荷对电机的冲击力大而频繁,使用现有联轴器不能满足需要,本文仅从理论上导出适 At present, all kinds of couplings in our country are not suitable for the cone rotor brake motors. This is because the coupling used in the cone rotor brake motors not only transmits the torque, but also extends axially when the motor starts, Axial retraction, the coupling needs to move axially flexible, lifting the industry with a tapered motor, the load on the impact of large and frequent motor, the use of the existing coupling can not meet the need, this paper only theoretical derived
