Couplings in various forms to choose the appropriate installation

The coupling we usually see is toothed embedded, which has a sealing effect, the coupling has higher quality requirements for lubricating oil, and the flow requirements are also higher, so it is necessary to check and supplement lubrication frequently;Although it is more troublesome, it can transmit a large distance, so it is the choice of large instruments.The type of shrapnel we use is also sealed, but the requirements are not harsh, and can be adjusted according to the actual situation, and the slider type is also more commonly used, which can be directly filled with oil lubrication, and can also be stuffed with oil soaked felt.

Although the form of the coupling is diverse, it is still necessary to choose according to the time of the machine, so as to ensure normal installation and operation.At the time of selection, the external size of the 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 it is more convenient to disassemble.We should note that if it is a large equipment, because it is more difficult to adjust, it should choose more wear-resistant and longer service life components as much as possible, which can delay the maintenance cycle and reduce the trouble and cost of replacement and debugging.

At present, many enterprises have widely used better performance diaphragm components, which not only has a long service life, but also is easier to maintain, and can effectively improve production efficiency.Coupling is an important device used in many large transmission instruments, the operation of this part directly affects the efficiency and service life of the instrument, so it should be given considerable attention, not only to choose the appropriate device, but also to pay attention to the usual maintenance, if necessary to replace in time to ensure the safety of operation.

The height of the inner gear ring of the coupling can not be changed at will, mainly because the travel of the gear shaper is limited, the height of the inner gear ring is too high, which will cause the bed to dry, and it will be processed in the larger gear shaper, which affects the work efficiency and increases the cost price.The inner tooth ring height of the coupling shall not be higher than 80, only limited to the gear coupling with an outer diameter of 300 or less.The inner gear ring with an outer diameter of more than 300 will have a gland, which can be removed first and processed by wire cutting to replace the operation of the gear shaper.
