Characteristics, advantages and disadvantages of various coupling

Coupling is an important device used in many large transmission devices. The operation of this component directly affects the working efficiency and service life of the device. Therefore, considerable attention should be paid not only to the selection of appropriate devices, but also to the maintenance in peacetime, and timely replacement when necessary.

Now we usually see the coupling mainly teeth embedded, this is sealed, the quality of lubricant requirements are higher, and the flow requirements are also higher, so often check and supplement lubrication; although more troublesome, but its transmission distance is larger, so it is the first choice of large equipment. The use of shrapnel type, although it is also sealed, but the requirements are not harsh, can be adjusted according to the actual situation. There have been slider type is also more commonly used, can be directly oil-filled lubrication, can also be filled with soaked felt.

Although the forms of coupling are various, they should be selected according to the time of the machine, so as to ensure the normal installation and operation. The basic principle is that the external dimensions of the selected components should not be too large, they must be accommodated by the installation space, and they need to leave some room for observation and maintenance at any time, and they are more convenient when they need to be disassembled. It should be noted that if it is a large-scale equipment, it is difficult to adjust, so as far as possible to choose more wear-resistant and longer service life components, which can delay the maintenance cycle, reduce the trouble and cost of replacement and commissioning. At present, diaphragm components with better performance have been widely used in many enterprises. They not only have long service life, but also are easier to maintain and can effectively improve production efficiency.
