What method does iko bearing oil seal not leak?

First, iko bearing oil seal works

1. In the free state, the inner diameter of the oil seal lip is smaller than the shaft diameter and has a certain amount of interference.

2. After installation, the interference pressure of the oil seal edge and the contraction force of the self-tightening spring generate a certain radial pressure on the rotating shaft.

3 , working, the oil seal lip under the action of radial pressure, forming a 0.25 to 0.5 mm wide sealing contact ring. Under the effect of lubricating oil pressure, oil penetrates between the edge of the oil seal and the shaft to form a very thin layer of oil film. The internal friction of the lubricant at the contact point and the stirring and squeezing of the lubricant are affected by the surface tension of the oil. A “crescent” surface is formed along the outer edge of the shaft and the edge of the oil seal to prevent oil spillage and seal. .

Second, the oil seal is not strict and lead to oil leakage how to do? The stage car price teller tells you the following method:

1 , master and identify the basic knowledge of shoddy products, buy high-quality, standard oil seals.

2. When installing, if the shaft surface roughness is low or there are rust, rust, burrs and other defects, use a fine emery cloth or oil stone polished smooth ; apply oil or grease to the oil seal lip or shaft diameter corresponding position. The outer seal of the oil seal is coated with a sealant, and the keyway portion of the shaft is wrapped with stiff paper to avoid scratching the lip of the seal, and the oil seal is rotated inward with a special tool. The hard seal cannot be used to prevent deformation of the seal. Or break the spring and fail ; if there is a lip flange, spring off and oil seal skew must be removed and re-installed. It should be noted that the price of the stage car organizer tells you not to tighten the inner spring when the shaft diameter is not worn and the spring force of the oil seal spring is sufficient.

3. Oil seals applied to agricultural machinery are generally inspected, maintained and maintained when the working conditions are generally poor, the temperature difference between the environment is large, the dust is excessive, and the machine vibrations frequently cause changes in the mechanical conditions of the components.

4 , the stage car price organizer tells you if the shaft diameter and iko bearing wear serious ; oil seal rubber aging or spring failure, etc., should be promptly repaired and replaced the corresponding parts.

5 , the abnormal heating components or assemblies should be promptly troubleshooting ; to avoid mechanical overspeed, overload operation, to prevent the oil seal lip temperature, rubber aging, early wear lips and so on.

6. Always check the oil level. If there are too many impurities in the oil, replace the new oil with alloy powder and metal scrap. The brand and quality of the replaced oil must meet the requirements of the season.

7. Oil seals that are not used temporarily should be properly kept away from oil, dust or sun exposure.

8 , when the shaft diameter wear into " v "-shaped groove, so that the new oil seal lip and shaft contact pressure can not play the role of sealing oil, you can use ar a 5 two-component adhesive repair, both simple and reliable and wear . Oil seal displacement can also be used to make up for.
