 ● LMZ-I-type split brake wheel plum flexible coupling, the scope of application and performance characteristics. 
 1.LMZ-I-type split brake wheel plum flexible coupling consists of two with protruding teeth closely mesh and subjected to radial extrusion to transmit torque when the two axes relative offset of the elastic element corresponding elastic deformation, has played the role of automatic compensation. 
 (2) the plum blossom elastic coupling is mainly used for starting frequently, rotating, high-speed, medium torque and high reliability is required in the workplace, such as: metallurgy, mining, petroleum, chemicals, lifting, transportation, light industry, textile, pumps, fans, and so on. Operating temperature -35 ℃ ~ +80 ℃, transfer nominal torque of 25 to 12500Nm allowable speed of 15 ~ 15300r/min. 
 (3), compared with other coupling elasticity coupling has the following characteristics: 
 (1) is stable and reliable, with good shock absorption, cushioning and electrical insulation properties. 
 (2), the radial size is small, light weight, small moment of inertia for high-speed situations. 
 (3) has a larger axial, radial and angular to the ability to compensate. 
 (4) wear oil resistant high-strength polyurethane elastomer components, carrying capacity, long life, safe and reliable. 
 (5) coupling requires no lubrication, low maintenance, can run for a long. 

 2: clamping splined plum type flexible coupling polyurethane plastic elastic component, has the advantages of cushioning, shock absorption, abrasion resistance, easy disassembly, etc., operating temperature -35 to +80 degrees. Interchange with the West German ROTEX coupling. Polyurethane elastomer by the convex claw block limit, to avoid the external deformation due to the impact of the internal deformation and centrifugal force; convex claw concave, involute surface pressure is very small, even if the teeth on withstand overload teeth still will not wear or deformation 
 3: LMZ-II (the original MLL-Ⅱ) with brake wheel elasticity coupling: 
 LMZ-II (the original MLL-Ⅱ) with the brake wheel elasticity coupling by two convex claw shape of a half coupling and elastic components, the use of the plum-shaped elastic element placed in the two halves of the coupling convex between the claws in order to achieve the connection of the coupling halves. Has to compensate for the relative offset of the two axes, vibration reduction, buffer, radial, small size, simple structure, without lubrication, higher carrying capacity, easy maintenance, etc., but the replacement of the elastic element coupling halves subject to axial movement. Apply to join two coaxial, and start frequently, positive change in low-speed, small and medium power drive shafts require the work of the high reliability of the work site, not for heavy load and the axial dimension restricted to, the replacement of the elastic element two axis in difficult parts. 
 Standard revised, plum-shaped elastic element materials are both polyurethane and cast-shaped nylon. Use of different materials under different conditions, such as fans, pumps, light industry, textile work is steady, and little load changes, the choice of polyurethane. The price gap between the two materials. 
 4: ● the LMS (original MLS) - double flange type plum-shaped elastic coupling of the scope of application and performance characteristics 
 1.LMS (original MLS) - double flanged plum-shaped flexible coupling consists of two close engagement and to withstand the radial extrusion torque transmission when the two axes relative offset, the elastic element with protruding teeth the elastic deformation occurs, play the role of automatic compensation. 
 (2) the plum-shaped flexible coupling is mainly used for starting frequently, rotating, high-speed, medium torque and high reliability is required in the workplace, such as: metallurgy, mining, petroleum, chemical, lifting, transportation, light industry , textile, pumps, fans, and so on. Operating temperature -35 ℃ ~ +80 ℃, transfer nominal torque of 25 to 12500Nm allowable speed of 15 ~ 15300r/min. 

 5: The LMD (the original MLZ) single-flange elasticity coupling with protruding teeth by two close engagement and to withstand the radial extrusion to transmit torque when the two axes relative offset of the elastic element corresponding the elastic deformation, to play the role of automatic compensation. 
 Plum-shaped coupling is a whole plum-shaped elastic ring mounted on the clamp between the two the same shape as the coupling half to two halves of the coupling connection. Squeezed between the transmission of power in the convex claw and elastic rings, the two axes relative offset of the compensation by the elastic deformation of the elastic ring to achieve the damping buffer. This coupling has been standardized, the GB/T5272-2002 to develop the five structural forms: LM-shaped (basic), The LMD-type (single flange type), the LMS-type (flange type), LMZ-Type I ( split brake wheel type) and LNZ-II (full brake wheel type). Each form are 14 specifications, they apply to the shaft hole diameter d = 12-160mm shaft hole length L = 35-135mm, nominal torque T-= 25-25000N.m allowable speed [n] = 1500 - 15300r.min. 

 6: ML plum-shaped flexible coupling consists of two with protruding teeth closely meshing and automatic compensation to withstand radial extrusion torque transmission, when the two axes relative offset, the elastic component of the corresponding elastic deformation, play role. (2) the plum-shaped flexible coupling is mainly used for starting frequently, rotating, high-speed, medium torque and high reliability is required in the workplace, such as: metallurgy, mining, petroleum, chemical, lifting, transportation, light industry , textile, pumps, fans, and so on. Working temperature: -35 ° C ~~ 80 ° C, and the passing public, said torque 25 ~ 12500Nm allowable speed of 15 ~ 15300r/min.
