Analyze the characteristics of the diaphragm coupling and the difference between the plum coupling

Diaphragm elastic coupling is one of the flexible couplings with metal elastic elements, which has obvious shock absorption, no noise, no wear. High transmission efficiency, up to 99.86%. Especially suitable for medium and high speed power transmission. Adapt to high temperature (-80+300) and harsh environment, and can operate under shock and vibration conditions. A diaphragm coupling is composed of a single piece or several diaphragms stacked together to transmit motion and power. Its elastic element is a thin gasket-like metal reed (diaphragm). The diaphragm coupling is very delicate and can be easily damaged if misused or improperly installed in use. Therefore, it is very necessary to ensure that the deviation is within the tolerance range of the normal operation of the coupling. Mainly suitable for servo motor, encoder, planetary reducer, ball screw, compressor, mixer, paper machinery, robot and other mechanical equipment

The plum couplings are machined by turning, milling and broaching, and then subjected to integral heat treatment. In order to ensure sufficient mechanical strength, there is also a claw disc casting on the market, which can be produced in large quantities and eliminates processing loss. So the price is much lower than that of machining, but the performance of casting is not very good, and it is still not used in some important occasions. It has good balance and is suitable for high rev applications (up to 30,000 RPM), but cannot handle large deviations, especially axial deviations. Large eccentricity and deflection angles can produce a larger bearing load than other servo couplings. Mainly suitable for encoder, servo system, motor spindle drive, packaging machinery, machine tool drive, pump and other machinery.

According to the characteristics of the above plum coupling and diaphragm coupling, you can distinguish the selection of the appropriate model, of course, but also reference torque and revolution, in many standard coupling, the correct choice of the coupling in line with the need, related to the performance of mechanical product transmission, Such as reliability, service life, vibration, noise, energy saving, transmission efficiency, transmission accuracy, economy and a series of problems, but also related to the quality of mechanical products.
