　　1. Diaphragm couplings are often used in servo systems. Diaphragms have good torque rigidity, but are slightly inferior to bellows couplings. 2. The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the sleeve by the pin and generally will not loosen or cause the diaphragm...

　　The overall dimensions of the chain coupling, that is, the maximum radial and axial dimensions, must be within the installation space allowed by the machine and equipment.It should be selected for easy assembly and disassembly, no maintenance, long maintenance period or convenient maintenance, and no need to move the two shafts to replace the wearing parts. ...

　　Couplings are used in a variety of different host products, and the surrounding working environment is relatively complicated, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive media, salt water, radiation and other conditions. ...

　　The assembly of the coupling on the shaft is one of the keys to the installation of the coupling.Most of the couplings and shafts are fitted with interference fits. The connection is divided into keyed and keyless connections. The shaft hole of the coupling is divided into two forms: cylindrical shaft hole and tapered shaft hole.The assembly methods are: static...

　　When customers don’t know how to choose a model, they often ask: With so many sizes, each model has so many shaft hole diameters and so many shaft hole lengths, how should I choose?The diameter of each shaft hole is selected according to the national standard data, and...

　　In order to prolong the life of the coupling, the following points should be done: 1. Before installation, the end faces of the two shafts should be cleaned, and the coordination of the key grooves on the end faces should be checked. 2. After installation, all screws must be checked after normal operation for one shift. If they are found to be loose, they must be tightened. This...

　　The start, stop, or forward and reverse rotation of the motor may impose a greater load on the coupling than the "maximum torque of the motor". Therefore, when designing and manufacturing the coupling, ensure that the maximum load torque applied to the coupling is ensured. Below "rated torque".Apply super...

　　Universal couplings have a variety of structural forms, common cross-shaft universal couplings and ball cage universal couplings.The common feature of universal couplings is that the angular compensation is large. The angle between the two axes of universal couplings of different structures is different, generally between 5 and 45 degrees...

　　Due to various reasons, the center of mass or inertial principal axis of the coupling does not coincide with the axis of rotation, and the phenomenon of unbalanced centrifugal inertial force, centrifugal inertial couple force and dynamic deflection (vibration shape) will be generated during operation, which is called the unbalance of the rotor. Phenomenon, this imbalance must...

　　Cross slide couplings are widely used in general machinery, hydraulic machinery, engineering machinery, metallurgical machinery, mining machinery, chemical machinery and other occasions. 1. The main shaft sleeve is made of aluminum alloy, which is light and handy; 2. The middle cross slider is available in a variety of different colors...
