LMZ-Ⅱ (formerly MLL-Ⅱ) plum-shaped elastic coupling with brake wheel
Summary: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) type quincunx elastic coupling with brake wheel is composed of two half-couplings with the same shape of 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.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 shafts, and working parts that require high working reliability. It is not suitable for heavy loads and limited axial dimensions. After replacing elastic components The two axes are difficult to align.
After the revision of the standard, the plum-shaped elastic elements are made of polyurethane and cast nylon.According to different working conditions, choose different materials, 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.
