Characteristics and applications of rigid couplings

The rigid coupling has good startability, which can transform the load starting of the motor into no-load transmission, realize the soft start of the working machine, reduce the starting current, adjust the transmitted torque, realize overload protection, have compensation performance, and be connected with flexibility. The shaft is matched with mechanical transmission performance.It is suitable for mechanical equipment that starts with load or frequently starts without speed adjustment, such as centrifugal pumps, blowers, air compressors, belt conveyors, scraper conveyors, mixers, ball mills, etc.The working principle and characteristics are the same as the steel ball coupling, but the structure, shape and working process are different. The steel ball type uses the rotor as the active end, and the steel sand type uses the shell as the active end. Like the steel ball type, the steel grit can be changed. The filling amount is used to adjust the transmitted torque and realize the function of overload protection.By changing different springs to adjust the sliding torque of the coupling, the impact load during starting can be partially slowed down, and it will automatically slip when the load is lifted, which plays a role of overload protection.The transverse speed, connection and running balance can not only be used for overload protection and no-load starting, but also mainly used for clutch, tension control, servo mechanism, speed regulation, test loading, commutation, etc. It is usually called a magnetic powder clutch.
