LMZ-Ⅱ(MLL-Ⅱ) Plum-shaped elastic coupling with brake wheel

　　LMZ-Ⅱ(MLL-Ⅱ) type with brake wheelQuincunx elasticCouplingIt is composed of two half-couplings with the same shape of the protruding claws and elastic elements. The plum blossom-shaped elastic element is placed between the two half-coupling claws to realize the coupling of the two coupling halves.It has the characteristics of compensating for the relative offset of the two shafts, damping, buffering, small radial size, simple structure, no lubrication, high carrying capacity, convenient maintenance, etc. However, the two halves of the coupling must be moved in the axial direction when replacing the elastic element.It is suitable for connecting two coaxial lines, frequent starting, forward and reverse changes, medium and low speed, medium and small power transmission shaft systems, and working parts that require high working reliability. It is not suitable for heavy loads and restricted axial dimensions, after replacing elastic components The two axes are difficult to align.

　　After the revision of the standard, the plum-shaped elastic elements are made of polyurethane and cast nylon.According to different working conditions, choose different materials, such as fans, water pumps, light industry, textiles, etc. When the work is stable and the load changes little, polyurethane can be selected.The grids of the two materials are quite different.

　　Plum couplingHas the following characteristics: plum shapeFlexible couplingThe structure is simple, the radial size is small, the weight is light, and the moment of inertia is small. It is suitable for medium and high speed applications. The plum-shaped elastic coupling works stably and reliably, and has good vibration damping, buffering and electrical edge performance.The quincunx-shaped elastic coupling has large axial, radial and angular compensation capabilities. The quincunx-shaped elastic coupling has high-strength polyurethane elastic elements that are wear-resistant and oil-resistant, have large load-bearing capacity, long service life, and reliability. No coupling is required. Lubrication, low maintenance workload, continuous long-term operation.

　　梅花形弹性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。

　　The 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.
