LMS (formerly MLS) type-double flange plum blossom elastic coupling
Summary:LMS double flange plum coupling is mainly suitable for frequent starting, forward and reverse rotation, medium and high speed, medium torque and high reliability work occasions, such as: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, Textiles, water pumps, fans, etc.
LMS (formerly MLS) type-double flange type plum blossom elastic 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 will respond accordingly. Elastic deformation plays a role of automatic compensation.
LMS双法兰梅花联轴器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。
Compared with other couplings, LMS (formerly MLS) type-double flange plum blossom elastic coupling has the following characteristics:
(1) Stable and reliable work, with good vibration damping, buffering and electrical insulation properties.
(2) The structure is simple, the radial dimension is small, the weight is light, and the moment of inertia is small, which is suitable for medium and high speed occasions.
(3) It has large axial, radial and angular compensation capabilities.
(4) High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and are safe and reliable.
(5) The coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.
