Characteristics, application and principle of steel grit coupling

The characteristics, application and principle of the steel grit coupling are basically the same as the steel ball coupling, but the structure and shape have 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 increases, and the shell and the rotor reach a synchronous operation state. At this time, the rotor and the shell no longer exist The speed difference.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, which can transform the heavy-load starting of the motor into an almost no-load starting, which can solve many problems of large horse-drawn carts that are common in electromechanics and match the capacity of the motor with the power of the working machine. Rationalize, save motor capacity, improve power factor of power grid, reduce reactive power loss, reduce starting current and starting energy consumption, simplify motor equipment, and reduce equipment costs.

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.
