Plum type elastic coupling is mainly a plum shaped elastic ring material respectively installed in the two half coupling between the convex claw by two two half coupling and connected.

一, plum type elastic coupling structure:

Plum type elastic coupling installed in two shape of the same half coupling between the convex claw, in order to achieve the connection of the two half coupling, through the extrusion between the convex claw and the elastic element transfer power, the elastic deformation of the elastic element can compensate the two axis relative offset, to achieve vibration damping buffer. It can be seen from the analysis that the petals of the plum shaped rubber body are only under pressure, but no longer bear the bending moment, which can bear greater load and has better reliability.

二, plum type elastic coupling performance:

1, plum type elastic coupling elastic components approximately plum shaped, the coupling has the compensation of two axis relative offset, vibration reduction, buffering performance, small diameter size, simple structure without lubrication, high bearing capacity easy maintenance, replacement elastic components need to move axial, suitable for connecting coaxial line, starting frequently, positive and negative changes, medium speed, Transmission shafting with medium torque and working parts requiring high reliability. It is not suitable for the difficult parts in the two axial pairs after the replacement of the elastic element with low speed and heavy load and limited axial size. The couplings are machined by turning, milling, broaching and other machining methods, and then subjected to integral heat treatment to ensure adequate strength.

2, plum type elastic coupling has good balance performance and is suitable for high speed applications, but can not deal with a large deviation, especially axial deviation. Larger eccentricity and deflection will produce larger bearing loads than other servo couplings. Another concern is the failure of the quince-shaped elastic coupling. If the spring spacer is damaged or fails, the torque transfer is not interrupted, and the metal claws of the two bushings mesh together to continue the torque transfer, which is likely to cause problems in the system. It is a great advantage of this coupling to select the appropriate material of the spring spacer according to the actual application. Different hardness and temperature bearing capacity allow customers to choose the appropriate material to meet the performance standards of the actual application.

Plum type elastic coupling in the industry is mostly used in automobiles, machinery and other equipment, because the plum type elastic coupling in the process of transferring torque is only subjected to extrusion pressure, but not by the rotating parts usually by the torque, in the process of use is not easy to wear, the service life is greatly improved.
