Many companies do not know that they will do maintenance on the coupling after purchasing the coupling, thinking that as long as it can be used, it will be fine. Now we will introduce to you the maintenance methods of several couplings and how to choose lubricating fluid.

Many companies do not know that they will do maintenance on the coupling after purchasing the coupling, thinking that as long as it can be used, it will be fine. Now we will introduce to you the maintenance methods of several couplings and how to choose lubricating fluid.

The first type of coupling type: cross slider type coupling: its maximum peripheral speed is about 30m/s, choose to use No. 2 grease for lubrication, fill the space of the middle slider with grease, and change the grease in general The cycle is 1000 hours, so it is suitable to use ball bearing grease. The corresponding maximum peripheral speed is about 30m/s, lubricated with N220 gear oil, the open space of the middle slider is filled with oil, the oil change cycle is 1000 hours, and sometimes an oil-soaked felt pad is used.

2. Jaw coupling: The maximum peripheral speed is about 150m/s, lubricated with N150 and N220 gear oil, and sufficient flow is required to pass through the coupling continuously in the axial direction without sealing.

3. Disc spring coupling: *The maximum peripheral speed is about 60m/s, lubricated with No. 2 or No. 3 grease, the amount is to fill the coupling, the grease change cycle is 12 months, and the sealing requirements are not strict;* The high peripheral speed is about 150m/s, and it is lubricated with N150 and N220 gear oil. It requires sufficient flow to pass through the coupling continuously in the axial direction.

4. Spring leaf coupling: The maximum peripheral speed is about 30m/s, lubricated with No. 1 grease, the amount is to fill the coupling, the grease change cycle is 1000 hours, and the sealing requirements are not strict.

Therefore, many couplings need correct lubrication methods. Only in this way can the coupling you buy be kept in use for a long time.
