LMZ-Ⅱ (formerly MLL-Ⅱ) type integral plum blossom coupling with brake wheel detailed parameters

The LMZ-Ⅱ (formerly MLL-Ⅱ) type of plum blossom elastic coupling with brake wheel is composed of two half-couplings with the same shape of the protruding claws and elastic elements. The plum-shaped elastic element is used to place the two halves of the coupling Between the claws to realize the coupling of the two halves of the coupling.After the revision of the standard, the plum-shaped elastic elements are made of polyurethane and cast nylon.Choose different materials according to different working conditions, such as fans, water pumps, light industry, textiles, etc. When the work is stable and the load changes little, polyurethane can be selected.The prices of the two materials are quite different.It has the characteristics of compensating the relative offset of the two shafts, damping, buffering, small radial size, simple structure, no lubrication, high carrying capacity, convenient maintenance, etc. However, the two halves of the coupling must be moved in the axial direction when replacing 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 replacing elastic components Difficult to align the two axes.
