Shaanxi LM type plum blossom coupling

The LM type plum blossom coupling is composed of two half couplings with the same shape of the claws and elastic elements. The plum blossom-shaped elastic element is placed between the two halves of the coupling claws to realize the coupling of the two halves. Join.When replacing the elastic element, the two halves of the coupling need to move along the axial direction to achieve the purpose of replacing the elastic element.The allowable relative displacement of the two shafts connected is not only related to the size, but also related to the shape of the working part of the elastic element. For the quincunx-shaped elastic element in contact with the torch-shaped claw, the allowable radial displacement △y is 0.2mm , The angular displacement △a is 1.5°. For the quincunx-shaped elastic element in contact with the arc-shaped convex claw, the allowable radial displacement △y is 0.5~1.8mm, and the allowable axis l-direction displacement △x is 2~5.0mm, The allowable angular displacement △a is 1.0°~2.0°.When the work needs to improve the compensation performance, and the load-bearing capacity is allowed to be slightly reduced, it can also be made into a plum-shaped elastic element that is drum-shaped in the axial direction, or the claws of the two halves of the coupling can be made into a convex form.

The scope of application of LM plum blossom coupling

1. LM plum blossom coupling is mainly composed of two protruding teeth that are closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element undergoes corresponding elastic deformation, which plays a role of automatic compensation.

2.LM typePlum coupling主要适用于起动频繁、正反转、中高速、中等扭矩和要求高的工作场合，例如：冶金、矿山、石油、化工、起重、运输、轻工、纺织、水泵、风机等。工作环境温度-35℃～80℃，传递公称扭矩25～12500Nm，许用转速1900～15300r/min。
