LMS (formerly MLS) type-double flange plum blossom elastic coupling

　　LMS (formerly MLS) type-double flange type plum blossom elastic coupling is mainly composed of two protruding teeth closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element will respond accordingly Elastic deformation plays a role of automatic compensation.
　　Plum coupling主要适用于起动频繁、正反转、中高速、中等扭矩和要求高可靠性的工作场合，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1500～15300r/min。

Note: 1. Mass and moment of inertia are calculated as approximate values for the small shaft hole recommended by L. 2. The shaft hole diameter with * can be used for Z-type and J-type shaft holes. 3. A and b are the hardness codes of the two materials. 4. L0 is the total length of the coupling when the length of the shaft holes at both ends is L recommended. 5. Type Y is a long cylindrical shaft hole. Type J1 is a short cylindrical shaft hole without counterbore. Type J is a short cylindrical shaft hole with a counterbore, and Type Z is a conical shaft hole with a counterbore.
