Features of steel grit coupling

　　Steel gritCouplingThe characteristics, applications, and principles of the steel ball coupling are basically the same, but the structural shape has worked differently.The working principle of the steel grit coupling is: when the motor is started, the motor drives the shell to rotate, and the inner surface of the shell drives the steel grit to rotate through friction, thereby driving the rotor connected to the driven shaft to rotate. Therefore, the motor is similar to Start without load.With the acceleration of the motor speed, the steel grit is close to the inner wall of the shell under the action of centrifugal force, the friction between the steel grit and the shell gradually, the shell and the rotor reach a synchronous operation state, at this time there is no more speed difference between the rotor and the shell .It usually only takes a few seconds from starting to synchronous operation of the master and slave axes.

　　The steel grit coupling is the same as the steel ball coupling. The transmitted torque can be adjusted by changing the filling amount of steel grit, which is easy to achieve overload protection.When the working machine is overloaded or stuck, the coupling can automatically slip to prevent the motor from burning out or other important parts from being damaged.

　　The steel grit coupling is the same as the steel ball coupling. It can also transform the heavy-load starting of the motor into an almost no-load starting. The power matching is rationalized, the motor capacity is saved, the power factor of the grid is improved, the reactive power loss is reduced, the starting current and starting energy consumption are reduced, the motor equipment is simplified, and the equipment cost is reduced.
