Technical Field

The invention belongs to the technical field of transmission, and particularly relates to an elastic coupling with a brake wheel.

Background

In the production of steel rolling, a power shaft and a roller end shaft are usually connected by a coupler, and in the rolling process, when the working torque is overloaded or other accidents happen, the coupler needs emergency braking to interrupt the transmission of torque, so that a motor and related equipment are effectively protected, and the elastic coupler with a brake wheel is widely applied under the condition. However, the existing elastic coupling with the brake wheel has the following defects: one is that the brake wheel and the shaft sleeve adopt an integral structure, the elastic coupling of the structure has low material utilization rate and high manufacturing cost, when the brake element is damaged, the integral structure needs to be replaced, which brings trouble to maintenance and adjustment, increases the maintenance cost and difficulty and affects the working efficiency; the other type is that the brake wheel and the shaft sleeve are connected in a welding mode, the elastic coupling of the structure is affected by welding strength, when the elastic coupling is subjected to large impact load, the overall reliability is poor, and potential safety hazards are brought to production.
