The cost performance can reflect that the matching transmission parts of the fan include plum coupling, star coupling and diaphragm coupling. These three series of products are somewhat similar in structure to the star, and the connection method is also the same. Yes, there is a middle cross polyurethane elastic pad for connection. The plum blossom coupling and the star coupling are composed of two half couplings with the same shape of the claws and elastic elements. The plum blossom elastic elements are used to place the two half couplings. Between the prongs of the shaft to realize the coupling of the two halves of the coupling. When replacing the elastic element of the basic quincunx elastic coupling, the two halves of the coupling need to move along the axial direction to achieve the purpose of replacing the elastic element. The stainless steel diaphragm is connected by the elasticity of the stainless steel sheet, which has good stability. The twisted hole bolts are used as the connecting parts. The appearance is obviously different from the former, but they all have shock absorption performance. In line with the requirements of fan working conditions, the diaphragm coupling consists of several groups of diaphragms (stainless steel thin plates) that are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is composed of several pieces stacked together, and the diaphragms are divided into connecting rods. And different shapes of the whole piece. The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the two shafts connected. It is a high-performance flexible coupling with strong metal components. It does not require lubrication, and has a compact structure, high strength and long service life. , No rotation gap, not affected by temperature and oil pollution, with acid and alkali resistance and corrosion resistance, suitable for high temperature, high speed, and corrosive medium shafting environment.
