The role of the rubber flap of the plum coupling

Plum coupling using quincunx elastic element between the two and a half coupling block in order to realize now half coupling elastic coupling, structure is simple, do not need to maintain, convenient maintenance, a buffer damping performance, wear resistance, the machining accuracy is not high, wide adaptation, can be used for all kinds of medium and small power of horizontal and vertical shaft system. Operating temperature -35 degrees to 80 degrees. The material of the plum-shaped elastic element is mainly polyester polyurethane rubber, which not only has high elasticity and oil abrasion resistance, but also has the advantages of impact resistance and oil resistance. In some cases, the elastic element can also be made of MC nylon 6 or NBR. It has the characteristics of compensating the relative offset of the two shafts, damping, buffering, small radial size, high bearing capacity and convenient maintenance, but when replacing the elastic element, the two halves of the coupling need to move along the axial direction. It is suitable for connecting two coaxial axes, starting frequently, positive and negative changes, medium and low speed, medium and small power transmission shafting, and the working parts requiring high reliability. It is not suitable for the parts with heavy load, limited axial size, and difficult alignment of two axes after the replacement of elastic elements.
