Shaanxi single diaphragm coupling

Single diaphragm couplingIt is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and others provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.The difference between the single diaphragm coupling and the double diaphragm coupling is the ability to handle various deviations. In view of the complex bending of the diaphragm, the single diaphragm coupling is not suitable for eccentricity.The double diaphragm coupling can bend in different directions at the same time to compensate for eccentricity.

Installation matters of single diaphragm coupling

①. The product with diaphragm has edges and may cause injury. It is recommended to wear thick gloves when installing.

②. Please install a protective cover and other devices around the coupling.

③. When the shaft center deviation exceeds the allowable value during installation, the coupling may be deformed and cause damage or shorten the service life.

④. The allowable shaft deviation of the coupling includes radial, angular, and axial deviation. When installing, please adjust the shaft deviation within the allowable range of the corresponding product catalog.

⑤. When multiple deviations appear at the same time, the corresponding allowable value should be halved.

⑥. In order to prolong the service life of the coupling, it is recommended to set the axis deviation within 1/3 of the allowable value.

⑦. Tighten the screws after inserting the mounting shaft, otherwise the coupling will be deformed. When tightening the screws, please use a torque wrench, do not use screws other than accessories for installation.

⑧. If an abnormal sound occurs during operation, please stop the operation immediately and check the installation accuracy and screw looseness respectively. It is recommended to apply adhesive on the outer surface of the screw after installation and debugging to increase the protection performance.

Single diaphragm couplings are widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power and chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, Mining machinery, metallurgical machinery, aviation (helicopter), naval high-speed power transmission systems, steam turbines, piston-type power mechanical transmission systems, crawler vehicles, and high-speed, high-power mechanical transmission systems of generator sets, which are applied to high-speed after dynamic balance Transmission shafting has become more common.
