Selection of coupling model

Published: 2020-10-18

The choice of coupling model is different according to different environments and the actual products required. The mechanical characteristics of the prime mover and the coupling, the type of prime mover are different, and the output power and speed of the prime mover are different, some are stable, and some are very shocking. Strongly, this will directly affect the choice of coupling model, which is one of the important reasons for choosing model.The shaft system of the coupling link and its operating conditions, for the mass size of the link shaft system, the size of the moment of inertia, and the variable speed or reversal, you should choose the elastic pin coupling. This type of coupling has a good cushioning and vibration absorption effect. .

The rotation speed of the coupling in operation is high or low. For high-speed two-axis links, you should consider choosing a coupling with high flat and constant accuracy characteristics to eliminate vibration and noise caused by centrifugal force. Among them, elastic diaphragm couplings are preferred , It is more practical for high-speed operation with low noise.Choosing the correct coupling model is conducive to the use of the machine, improving work efficiency and prolonging the life of various equipment.The front differential of the front wheel of the car cannot use the differential limited slip device for the coupling, because the front wheel is a steering wheel. If the differential of the differential is too large, it will affect the steering flexibility of the car.

Plum couplingIt is a very commonly used coupling. Clean the parts before installing the plum blossom coupling. After cleaning the parts, dry the oil on it.For couplings that are ready for operation in a short period of time, wipe the surface of the parts with turbine oil or engine oil to prevent rust.For couplings that need to be put into use for a long time, they should be painted with anti-rust oil for maintenance.Correctly install the main motor of the plum coupling and the equipment connected to the motor to correct the problem.

CouplingThe correct way to find the correct way is to fix the equipment connected to the motor, add the elastic plum blossom, install the motor, and correct the coupling with a ruler. The pad of the motor should be pad. If the motor is high, first fix the device connected to the motor. Aligning the motor.The correct installation of the coupling plays a very important role in the service life of the elastic element. The plum blossom coupling is widely used in the coupling.Therefore, the plum blossom coupling must be installed correctly.Plum blossom coupling installation features are double or multi-section design, which can reduce vibration and noise, and is suitable for various pumps; maintenance-free, compact design, low inertial momentum; length can be selected; explosion-proof certificate in line with European standards.The plum blossom coupling is oil-resistant and electrically insulated.

The compensation principle of the diaphragm is mainly to compensate for the manufacturing and installation errors and the deformation load caused by the operation of the machine, as well as the radial and angular deviations caused by the increase and decrease of the temperature.And because the diaphragm coupling is a flexible coupling with elastic elements, its inherent properties are elastic cushioning, no noise and no lubrication. It is an ideal product for general couplings at the moment.The production of diaphragm couplings is made up of at least two sleeve shafts or a combination of one diaphragm. Because the diaphragm is nailed to the sleeve shaft by professional nails, there will be no looseness or two diaphragms under normal circumstances. Conflict between.Of course, there will also be some manufacturers who provide us with two or three diaphragms with one or more rigid components in between.In this way, the diaphragm is divided into single-segment diaphragm coupling and double diaphragm coupling.The difference between them is that they can handle all kinds of deviations ingeniously, and compensate for the problem of center deviation at one time.

Diaphragm is the most core component in diaphragm coupling products. Diaphragms can be divided into many forms according to their shapes, but the basic compensation principles are the same.It plays an extremely important role in water pumps, hydraulic machinery, aviation and other fields.
