How about a diaphragm coupling? How does it work?

Anyone who is familiar with couplings knows that diaphragm couplings are suitable for mechanical equipment that starts with load or starts frequently without speed regulation, such as: air compressors, belt conveyors, centrifugal pumps, ball mills, blowers, Scraper conveyors and mixers, etc. This is mainly due to the good startability of this coupling, 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 safety protection, and have Certain compensation performance, matched with flexible coupling, can improve the mechanical transmission performance.

In order to improve the equilibrium state, the bolts should be installed in positive and reverse phases. The characteristics of the vertical diaphragm coupling are similar to those of the diaphragm coupling, the structure is simple, and the assembly and disassembly are convenient. Compensation performance in the heel angle direction.

The working principle and characteristics of the diaphragm coupling are similar to those of the steel ball safety coupling, but the structure, shape and working process are different. The steel ball type uses the rotor as the automatic end, and the steel sand type uses the shell as the automatic end. The ball type can also adjust the transmitted torque by changing the amount of steel grit filling, and realize the function of overload safety protection. Horizontal speed, connection, and balanced operation, not only can be used for overload safety protection and no-load starting, but also for clutch, tension control, servo mechanism, speed regulation, test loading, reversing, etc., usually called magnetic powder clutch. By changing the different springs to adjust the sliding torque of the coupling, it can partially reduce the impact load at the start of the transmission, automatically slip when the load is started, and play the role of overload safety protection.
