1: LMZ-I-type split brake wheel Plum flexible coupling: ● LMZ-I-type split braking wheel Plum scope of application and performance characteristics of the flexible coupling. 1.LMZ-type I split brake wheel plum flexible coupling is mainly composed of the convex teeth of the two belt closely engage and bear radially squeezed in order to transfer torque, the elastic member corresponding to the elastic deformation when the two axes relative offset, and to play the role of automatic compensation. . Plum blossom elastic coupling is mainly applied in the starter frequent, positive, high-speed, moderate torque and high reliability is required in the workplace, such as: metallurgy, mining, petroleum, chemicals, lifting, transportation, light industry, textile , pumps, fans, etc.. Operating ambient temperature -35 ℃ ~ +80 ℃, transmission nominal torque 25 ~ 12500Nm, allowable speed 1500 ~ 15300r/min. Compared with other coupling, plum blossom elastic coupling has the following characteristics: (1) stable and reliable, have good shock absorption, cushioning and electrical insulation properties. (2) simple structure, the radial dimension is small, light weight, small moment of inertia, applicable in high-speed situations. (3) having a large axial, radial and angular compensation capability. (4) high-strength polyurethane elastomer component wear-resistant oil, carrying capacity, long life, safe and reliable. (5) The coupling requires no lubrication, less maintenance, continuous long-term operation. 2: clamp-on the plum type flexible coupling spline polyurethane plastic elastic elements, with a buffer, cushioning, wear-resistant, easy to assemble and disassemble, etc., operating temperature of -35 to +80 degrees. Can be interchanged with the West German ROTEX coupling. Polyurethane elastomer by the convexly pawl block limit, can be avoided due to the impact-generating internal deformation and centrifugal forces generated by the external deformation; detents concave, so that the surface pressure on the involute small teeth even withstand overload teeth still will not wear or deformation 3: LMZ-II (original MLL-Ⅱ)-type flexible coupling with brake wheel Plum: LMZ-II (original MLL-Ⅱ) type with brake wheel elasticity coupling convex claw shape by two with the same coupling half and elastic components, quincunx elastic element is placed between the two coupling halves detents, in order to achieve the two coupling halves join. Compensation axis relative offset damping, buffering, small radial size, simple structure, no lubrication, higher carrying capacity characteristics, but replace the elastic element coupling halves need to move axially. Suitable for connecting two coaxial starter frequent, positive change in low-speed, small and medium power drive shafts require high reliability parts, not suitable for heavy-duty and axial dimensions restricted, replace the elastic element the two axes of the difficult parts. The standard amended, quincunx elastic element material polyurethane casting shaped nylon two. Selection of different materials under different conditions, such as fans, pumps, light industry, textile work smoothly when the load changes, the choice of polyurethane. The large price difference between the two materials. 4: ● LMS (the original MLS) type - double flange type quincunx elastic coupling scope and performance characteristics 1.LMS (the original MLS) type - double flange quincunx elastic coupling mainly by two with detents closely engage and bear radially squeezed in order to transfer torque, the elastic member corresponding to the elastic deformation when the two axes relative offset to play the role of automatic compensation. Quincunx elastic coupling is mainly applied in the starter frequent, positive, high-speed, moderate torque and high reliability is required in the workplace, such as: metallurgy, mining, petroleum, chemicals, lifting, transportation, light industry, textile, pumps, fans, etc. Operating ambient temperature -35 ℃ ~ +80 ℃, transmission nominal torque 25 ~ 12500Nm, allowable speed 1500 ~ 15300r/min. 5: (original MLZ) type LMD a single flange Plum elastic coupling mainly by two with protruding teeth closely engage and to bear radial compression to transmit torque when the two axes relative offset, the elastic element corresponding elastic deformation, play the role of automatic compensation. The quincunx coupling is an integral quincunx elastic ring mounted between the two the same shape as the coupling halves convex claw to realize the connection of the two coupling halves. Extrusion power is transmitted through the detents between the elastic ring, through the elastic deformation of the elastic ring to compensate for the two-axis relative offset to achieve damping buffer. This coupling has been standardized, GB/T5272-2002 developed five structural forms: LM-shaped (basic), LMD (single flange type), LMS-type (dual flange-type), LMZ-I type ( the split brake wheel type) and LNZ-II (Holistic brake wheel type). Each form has 14 specifications, they are applicable, the shaft hole diameter d = 12-160mm, the length of the shaft hole L = 35-135mm, and the nominal torque T = 25-25000N.m allowable speed [n] = 1500 - 15300r.min. 6: ML quincunx flexible coupling is mainly composed of the convex teeth of the two belt closely engage and to withstand radially squeezed in order to transfer torque, the elastic member corresponding to the elastic deformation when the two axes relative offset, to play the role of automatic compensation .
