The diaphragm coupling consists of several groups of diaphragms that are alternately connected to the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rod type and different shape of the whole piece type.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, no lubrication, compact structure, high strength and long service life. , No rotation gap, not affected by temperature and oil pollution, acid-resistant, alkali-resistant and corrosion-resistant, suitable for high-temperature, high-speed, and corrosive medium shafting environments.

　　The diaphragm coupling can compensate for the axial, radial and angular deviations between the driving machine and the driven machine due to manufacturing errors, installation errors, load-bearing deformations and the effects of temperature rise changes.The diaphragm coupling is a flexible coupling with a metal elastic element. It relies on a metal coupling diaphragm to connect the main and driven machines to transmit torque. It has the advantages of elastic vibration reduction, no noise, and no need for lubrication. It is a substitute for drums today. Ideal product for profile gear couplings and general couplings.

　　The main characteristics of the diaphragm coupling

　　1. The ability to compensate for the misalignment of the two axes is strong. Compared with the drum gear coupling, the angular displacement can be doubled, the reaction force is small during the radial displacement, the flexibility is large, and a certain axial, radial and Angular displacement.

　　2. It has obvious shock absorption, no noise and no wear.

　　3. It is suitable for working in high temperature (-80+300) and harsh environment, and can move under shock and vibration conditions.

　　4. The transmission efficiency is high, up to 99.86.Especially suitable for medium, high speed and high power transmission.

　　5. Simple structure, light weight, small size, convenient assembly and disassembly.It can be assembled and disassembled without moving the machine, and no lubrication is required.

　　6. It can accurately transmit the speed without slip, and can be used for the transmission of precision machinery
