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

The LMZ-Ⅱ(formerly MLL-Ⅱ) type brake wheel quincunx elastic coupling is composed of two half-couplings with the same shape of the claws and elastic elements. The plum-shaped elastic element is used to place the two halves of the coupling. Between the two halves of the coupling.

LMZ-Ⅱ (formerly MLL-Ⅱ) plum-shaped elastic coupling with brake wheel
　　LMZ-Ⅱ (formerly MLL-Ⅱ) typePlum-shaped elastic coupling with brake wheelIt 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 protruding claws to realize the coupling of the two halves of the coupling.It has the characteristics of compensating for the relative deviation of the two shafts, damping, buffering, small radial size, simple structure, no lubrication, high carrying capacity, and convenient maintenance.
　　 The two halves of the coupling need to move in the axial direction when changing 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 changing elastic components The two axes are difficult to center.
　　The LMZ-Ⅱ(MLL-Ⅱ) plum-shaped elastic coupling with brake wheel is mainly suitable for frequent starting, forward and reverse rotation, medium and high speed, medium torque and high reliability work occasions, such as: metallurgy, mining, Petroleum, chemical industry, lifting, transportation, light industry, textile, water pump, fan, etc.The working environment temperature is -35℃～+80℃, the transmission nominal torque is 250～12500N.m, and the allowable speed is 4750～950r/min.
