The characteristics and advantages and disadvantages of various couplings

Introduction:

Coupling is an important device to be used on many large transmission instruments, the operation of this part directly affects the efficiency and service life of the instrument, so should give considerable attention, not only to choose the appropriate device, but also to pay attention to the usual maintenance, timely replacement when necessary.

Main types of couplings commonly seen:

Now we usually see the coupling is mainly toothed embedded, this is sealed, the quality of the lubricating oil is higher, and the flow is also higher, so often check and supplement lubrication; Although it is troublesome, it is the first choice for large instruments because it can travel a large distance. And 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 has been a sliding block type is also more commonly used, can be directly filled with oil lubrication, can also be filled with oil soaked felt.

To sum up:

Although the form of coupling is diverse, but in the choice of time or according to the machine to choose, so as to ensure the normal installation and operation. The most basic principle is that the external size of the selected component can not be too large, must be able to be accommodated by the installation space, and need to leave some room for observation and maintenance at any time, when the need to disassemble is also more convenient. It should be noted that if it is a large equipment, it is more troublesome to adjust, so we should choose more wear-resistant and longer-life components as far as possible, so as to delay the maintenance cycle, reduce the trouble and cost of replacement and debugging. At present, many enterprises have begun to commonly use the better performance of the diaphragm element, which not only has a long service life, but also easier to maintain, can effectively improve production efficiency.
