Through reasonable, ingenious and simple design, the long cylindrical roller bearing with excellent lubricating performance can automatically maintain high-efficiency lubricating performance for a long time in the running and using process, the running performance and efficiency can be fully exerted, the oiling and maintaining frequency of the bearing is greatly reduced, the quality and the service life of a product are remarkably improved, and the use requirement is met.
Description
Technical Field
The utility model belongs to the technical field of the bearing manufacturing technique and specifically relates to a long cylindrical roller bearing with good lubricating property is related to.
Background
The long cylindrical roller bearing is a centripetal rolling bearing with long cylindrical rollers as rolling bodies, the cylindrical rollers are in line contact with the roller paths, the radial load capacity is high, and the long cylindrical roller bearing is suitable for bearing heavy loads and impact loads and is also suitable for high-speed rotation. The current cylindrical roller bearing is generally an open type roller bearing, namely an open type structure, the sealing performance is not enough, lubricating oil is often dripped when being injected, the lubricating oil overflows and runs off or volatilizes seriously in the running process of the bearing, the running performance of the bearing is reduced, the oiling maintenance work is further frequent, the production operation efficiency is influenced, and the service life of the bearing is also shortened.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the long cylindrical roller bearing with excellent lubricating performance is provided to solve the problems in the background art and meet the use requirements.
The utility model provides a technical scheme that its technical problem adopted is: a long cylindrical roller bearing with excellent lubricating property comprises a bearing outer ring, a bearing inner ring, a long cylindrical roller and a roller retainer, wherein the long cylindrical roller is embedded in a roller pocket hole of the roller retainer and is assembled on a roller path formed by corresponding roller path surfaces of the bearing outer ring and the bearing inner ring together with the roller retainer, oil locking and lubricating elastic cotton strips are axially arranged on the inner surface and the outer surface of a spacing part of adjacent roller pocket holes of the roller retainer, and the oil locking and lubricating elastic cotton strips are in contact with the roller path surfaces of the bearing outer ring and the bearing inner ring.
The oil-locking lubricating elastic cotton strip is made of a material which has good absorptivity, wear resistance, corrosion resistance, high temperature resistance and certain elasticity. The oil locking lubricating elastic cotton strips absorb lubricating oil injected into the bearing and can lock the lubricating oil for a long time, so that the oil is effectively prevented from overflowing and losing or volatilizing in the running process of the bearing; meanwhile, the oil-locking lubricating elastic cotton strips can also play a role in cleaning the roller way surface, and prevent dust and impurities from being adhered to the roller way surface in the rotating and scraping process.
Furthermore, the cross section of the oil locking lubricating elastic cotton strip perpendicular to the axial direction of the bearing is in an arch shape, and the arch tip part of each oil locking lubricating elastic cotton strip is elastically pressed against the raceway surface of the outer ring or the inner ring of the bearing according to the position of the oil locking lubricating elastic cotton strip.
The utility model has the advantages that: through reasonable, ingenious and simple design, the long cylindrical roller bearing with excellent lubricating performance can automatically maintain high-efficiency lubricating performance for a long time in the running and using process, the running performance and efficiency can be fully exerted, the oiling and maintaining frequency of the bearing is greatly reduced, the quality and the service life of a product are remarkably improved, and the use requirement is met.

Detailed Description
A long cylindrical roller bearing with excellent lubricating property is disclosed, as shown in figure 1, and comprises a bearing outer ring 1, a bearing inner ring 2, long cylindrical rollers 3 and a roller retainer 4, wherein the long cylindrical rollers 3 are embedded in roller pocket holes of the roller retainer 4 and are assembled on a roller path formed by corresponding roller path surfaces of the bearing outer ring 1 and the bearing inner ring 2 together with the roller retainer 4, oil locking and lubricating elastic cotton strips 5 are axially arranged on the inner surface and the outer surface of a spacing part of adjacent roller pocket holes of the roller retainer 4, and the oil locking and lubricating elastic cotton strips 5 are in contact with the roller path surfaces of the bearing outer ring 1 and the bearing inner ring 2.
The cross section of the oil locking lubricating elastic cotton strip 5 vertical to the axial direction of the bearing is in an arch shape, and the arch tip part of each oil locking lubricating elastic cotton strip 6 is elastically pressed against the raceway surface of the bearing outer ring 1 or the bearing inner ring 2 according to the position of the oil locking lubricating elastic cotton strip.
The oil-locking lubricating elastic cotton strip 5 is made of a material which has good absorptivity, wear resistance, corrosion resistance, high temperature resistance and certain elasticity. The oil locking lubricating elastic cotton strips 5 absorb lubricating oil injected into the bearing and can lock the lubricating oil for a long time, so that the oil is effectively prevented from overflowing and losing or volatilizing in the running process of the bearing, and because the oil locking lubricating elastic cotton strips 5 are in contact with the raceway surfaces of the bearing outer ring 1 and the bearing inner ring 2, the oil locking lubricating elastic cotton strips 5 adsorbing the lubricating oil can continuously oil and lubricate the raceway surfaces in the process that the oil locking lubricating elastic cotton strips 5 rotate along with the roller retainer 4, so that the raceway surfaces are always kept with oil films, and the bearing rollers are ensured to be lubricated for a long time; meanwhile, the oil-locking lubricating elastic cotton strips 5 can also play a role in cleaning the roller way surface, and prevent dust and impurities from being adhered to the roller way surface in the rotating and scraping process.
The above embodiments are only used for explaining the present invention, and not for limiting the protection of the present invention, and any insubstantial changes made on the basis of the essential schemes of the present invention should fall within the protection scope of the present invention.
