LM (ML) plum blossom couplingIt is mainly composed of two convex 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.
Ever-PowerLM(ML)梅花联轴器适用范围:主要适用于起动频繁、正反转、中高速、中等扭矩和要求高性的工作场合,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。
Ever-PowerLM(ML)Plum couplingWork stably, with good vibration damping, buffering and electrical insulation properties.The structure is simple, the radial dimension is small, the weight is light, and the moment of inertia is small. It is suitable for medium and high speed occasions.It has large axial, radial and angular compensation capabilities.Polyurethane elastic elements are resistant to oil, have large carrying capacity, and have a long service life.The coupling does not need to be lubricated, the maintenance workload is small, and it can run continuously for a long time.
The materials of the elastic elements are polyurethane and cast nylon.According to different working conditions, choose different materials, such as fans, water pumps, light industry, textiles, etc., when the load is stable and the load changes little, polyurethane can be selected.Most of the elastomers currently used are polyurethane.This coupling is widely used in water pumps, oil pumps, machine tools and other industries.
