The grease in the rolling bearing at the beginning of a complex flow, it entered a stable distribution state, left in the friction parts of a very small amount of fluid grease plays a major role in lubrication, and left in the cover of the grease itself does not flow, that is, no direct lubrication. But the bearing grease left in the outer cover plays a sealing role to prevent the flow grease left in the friction parts from flowing out.

How to prevent the addition of grease? First of all, the reasonable amount of grease should be determined. In addition, the operation specifications for the amount of grease should be formulated. After the addition and replacement of grease, attention should be raised, paying attention to temperature, noise, vibration, etc., and paying attention to whether there is oil leakage. For important equipment, special monitoring tools can also be used. Specify a reasonable amount of grease:

The amount of grease added to bearings can refer to this formula:

G=0.005 DB

Here:

G=fat added weight in grams

D=bearing outer diameter, mm

B=bearing width, mm

or

G=0.114 DB

Here, D and B are in inches.

If you use a butter gun and grease, you should calculate how much grease the butter gun can play each time. You can use an electronic scale, use a good butter gun, and calculate how many times to play.

In addition to knowing the amount of grease to be added, certain methods can also help to prevent excessive greasing:

When adding fat, you should stop adding if you find it difficult to add, if the addition is blocked, or if you begin to feel a greater reaction.

When adding grease, the oil outlet of grease should be kept unobstructed to prevent dry grease from blocking the hole.

If necessary, use some small accessories can also play a very convenient effect, such as the butter gun pressure gauge, with pressure relief function of the butter nozzle, etc.

Slow greasing, too fast and too fast are easy to cause sealing problems, and it is not conducive to the uniform distribution of grease in the bearing.
