Introduction

[LM plum coupling]

Flexible coupling, plum coupling

The plum coupling has a damping effect and is applied in the market earlier. It is an older type of coupling.

Flexible coupling

-The plum-shaped elastic coupling is composed of two semi-couplings with the same shape of the claws and elastic elements. The plum-shaped elastic element is placed between the two coupling halves to realize the two coupling halves. The connection.

- It has the characteristics of compensating the relative offset of the two axes, damping, buffering, small radial dimension, simple structure, no lubrication, high carrying capacity and convenient maintenance. However, when the elastic components are replaced, the two halves of the coupling need to move in the axial direction. .

-Suitable for connecting two coaxial lines, frequent starting, positive and negative rotation change, medium and low speed, medium and small power transmission shafting, high reliability requirements, not suitable for heavy load and axial size limitation, replacement of elastic components The rear two axes are in a difficult position.

-Special structure can be designed according to customer requirements;

-Coupling material can be selected according to customer requirements;

-The dimensions in the figure can be made according to customer requirements; other technical parameters can be consulted by Bnk Technology;
