Product details:

JM Ⅱ type without a sink hole basic diaphragm coupling consists of several groups of diaphragm (stainless steel thin plate) using bolt crisscross with half coupling, diaphragm composed of several pieces fold sets in each group, the diaphragm can be divided into connecting rod type and different shapes of the chip.

JM Ⅱ type without a sink hole basic diaphragm coupling on the elastic deformation of the diaphragm to compensate for the two axes relative displacement, is a kind of high performance metal flexible coupling components elastic, no lubrication, structure is compact, high intensity, long service life, no rotating clearance, not influenced by temperature and oil pollution, has the characteristics of acid and alkali resistance, corrosion resistance, suitable for high temperature, high speed, a shaft transmission of working condition of corrosive medium environment, widely used in all kinds of shaft transmission of mechanical device, such as the pump (especially high power), chemical pump, fan, compressor, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), ships high-speed power transmission system, the dynamic balance after applied in high-speed transmission shafting were common.

JM Ⅱ type without a sink hole basic compared diaphragm coupling, there is no relative sliding, do not need lubrication, sealing, no noise, basic need not repair, make convenient, part can replace type coupling. The application of diaphragm coupling in industrial developed countries is common in the world. In practice, intermediate shaft type is used to improve the offset performance of the two axes. Diaphragm coupling with several groups of diaphragm (stainless steel sheet) with crisscross connected to two and a half coupling bolt, each group has an array of diaphragm piece of folded set, diaphragm are divided into connecting rod type and different shapes of the chip. The eigenvalue of axial vibration of diaphragm coupling under various conditions is obtained, and the calculation formula of axial stiffness is derived from the theoretical basis, which is consistent with the natural frequency and experiment obtained by the formula.
