The torque of the contact surface of the Flexible Coupling causes surface wear

Flexible Coupling

The Flexible Coupling contains the elastic compound of preloaded rubber, which can provide additional strength and prolong the service life. The Flexible Coupling is easy to install. Because the rubber part is a split insert, it can be inserted after the shaft is aligned. Flexible Coupling is formed by wire cutting of round metal rod, and is an integrally formed metal elastomer. The common materials of Flexible Coupling include aluminum alloy, stainless steel and engineering plastics, which are suitable for various deviations and torque transmission. Flexible Coupling adopts parallel or spiral grooving system, which can adapt to various deviations and accurately transmit torque.

Flexible Coupling is usually made of polyurethane and nylon with high elasticity and toughness, which has high tensile strength and good toughness, and can play a very good role in shock absorption and displacement compensation. Due to the thin thickness, small volume and limited elastic deformation of the elastic sleeve, the pin connection of the elastic sleeve can compensate the axial displacement and elasticity, but the allowable compensation of the axial displacement is small and the elasticity is weak. The Flexible Coupling generates friction torque on the contact surface by the locking force of the pin group, and compresses the rubber elastic sleeve to transmit torque. The Flexible Coupling has buffering and damping performance, and has a certain capacity of shaft deviation compensation.

Flexible Coupling

The elastic element is sheared when working, and its working reliability is poor. It is suitable for medium speed transmission shaft system with very low requirements, but not for working conditions with high requirements for working reliability. The Flexible Coupling has good axial, radial and angular offset compensation performance, good vibration reduction performance, stable and reliable operation, noiseless, non-lubricated, simple maintenance, convenient handling, good workmanship, low cost, and can be derived into a variety of structural forms, with a wide range of applications. The outstanding advantage of the coupling is that it is only applicable to the working environment where the shaft is difficult to be aligned and installed, and it is required to minimize the auxiliary working time.

Flexible Couplings are usually made of circular metal rods by wire cutting. Common materials include aluminum alloy, stainless steel and engineering plastics. Flexible Couplings use parallel or spiral grooving systems to adapt to various deviations and transmit torque. The integral forming design enables the Flexible Coupling to realize zero-gap torque transmission and maintenance-free. When selecting the Flexible Coupling, pay attention to that the rated torque should be greater than the system load torque. We have considered the variable load factor during operation, so it is unnecessary to adjust the rated torque value during selection. Flexible Couplings are commonly used in equipment and are placed in the flange holes of the coupling halves.
