LMD (formerly MLZ) type single flange plum blossomFlexible 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.
The plum-shaped elastic coupling has the following characteristics: the flower-shaped elastic coupling has simple structure, small radial size, light weight, and small moment of inertia. It is suitable for medium and high-speed occasions. The plum-shaped elastic coupling works stably and has good vibration reduction, Buffer and electrical insulation properties.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 resistant to oil, large carrying capacity and long service life. The coupling does not require lubrication and maintenance The workload is small, and it can run continuously for a long time.
