Jiangsu LM plum blossom coupling
ML coupling is suitable for connecting two coaxial lines, frequent starting, medium and low speed, and medium and small power transmission shafts that require high workability. ML coupling is not suitable for heavy load and axial dimension receiving and changing elastic components. The latter two axes are difficult to align.
ML couplings are sometimes called LM couplings. The two models are called differently, but they are a plum coupling product, but there are some differences in models. We use ML couplings and LM couplings. The coupling model parameters are compared as follows, which can be clear at a glance when you choose the coupling.
LM (ML) 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.

How to analyze the cause of damage to the elastic pin coupling?And the classification of elastic pin couplingsElastic pin couplings are generally elastic pin couplings, nylon rod pin couplings, the former are connected by several screws, and the nut ends of the screws are equipped with elastic washers.The latter uses nylon rods. The two half-sections are drilled as large as holes, and the nylon rods are inserted. The outside is covered with a baffle, a pin coupling, and a pin coupling. The half couplings are connected by N nylon rods.Can play a compensation role...Take you to understand commonly used elastic couplingsCommonly used elastic couplings are divided into two types of elastic sleeve pin couplings and elastic pin couplings...
