The main characteristics and working range of diaphragm coupling are analyzed

Diaphragm coupling is a kind of compensation for the axial, radial and angular offset caused by the manufacturing error or installation error between the active machine and the engine, bearing deformation and temperature rise change. This KIND OF COUPLING BELONGS TO THE flexible coupling of metal elastic elements, which relies on the metal coupling diaphragm to connect the master and slave engines to transmit torque, has the advantages of elastic vibration reduction, no noise, no lubrication, and is an ideal product to replace the toothed coupling and the general coupling.

The main characteristics of diaphragm coupling are as follows:

1. The ability to compensate the misalignment of the two axes is strong, and the angular displacement can be twice as large as that of the toothed coupling. The reaction force is small when the radial displacement, and the flexibility is large.

2, with obvious shock absorption, no noise, no wear.

3, adapt to high temperature (-80+300) and harsh environment work, and can be in the impact, vibration conditions of safe operation.

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

5, simple structure, light weight, small volume, convenient assembly and disassembly. No need to move the machine can be assembled and disassembled (with middle shaft type), no lubrication.

6, can accurately transfer speed, no rotation, can be used for precision machinery transmission.

Diaphragm coupling is a shafting transmission that can be commonly used in every type of mechanical device. For example, we often use 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, steam turbine, piston mechanical power transmission system, tracked vehicles, And high speed and high power mechanical transmission system of generator set, which is applied to high speed transmission shaft system after dynamic balance has been relatively common.
