JMIJ to intermediate shaft diaphragm coupling
The JMIJ type intermediate shaft diaphragm coupling has a strong ability to compensate for the misalignment of the two axes, and the angular displacement can be twice as large as the gear coupling, and there is no relative sliding, no lubrication, sealing, no noise, and basically no maintenance , It is more convenient to manufacture and can partially replace the gear coupling.
The main feature of JMIJ inoculation inter-shaft diaphragm coupling is that the connecting shaft in the middle extends the connection distance, and the double diaphragm design increases the amount of flexibility compensation.It can accurately transmit the speed without slip, and can be used for mechanical transmission.In the transmission, the transmission reaches 99.86%, which is especially suitable for medium, high-speed and high-power transmission.Simple structure, light weight, small size, and can be assembled and disassembled without moving the machine.
The JMIJ type intermediate shaft diaphragm coupling compensates for the relative displacement of the connected two shafts by the elastic deformation of the diaphragms on both sides. The main feature is that it does not require lubrication, has a compact structure, has a long service life, does not rotate, and is not subject to temperature. It has the characteristics of acid and alkali resistance, and is suitable for high temperature, high speed, and corrosive medium operating conditions.
