Description
Technical Field
The utility model belongs to the technical field of the bearing manufacturing technique and specifically relates to a can mend lubricated long cylinder roller bearing of oil by oneself for a long time.
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 capable of automatically supplementing oil and lubricating for a long time is provided, so that the problems in the background art are solved, and the use requirements are met.
The utility model provides a technical scheme that its technical problem adopted is: a long cylindrical roller bearing capable of automatically supplementing oil and lubricating for a long time 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, the bearing outer ring is a hollow structure body, an oil filling hole communicated with an inner cavity of the bearing outer ring is formed in the outer circumferential surface of the bearing outer ring, a matched sealing plug is arranged on the oil filling hole, an oil penetrating hole communicated with the inner cavity of the bearing outer ring is formed in the roller path surface of the bearing outer ring, and lubricating oil is stored in the inner cavity.
In the running and using process of the bearing, lubricating oil which is injected into the inner cavity of the bearing outer ring in advance slowly enters the raceway for a long time through the oil penetration hole, the rotating long cylindrical roller 3 is continuously lubricated, and an oil film is formed on the raceway surface and the surface of the long cylindrical roller 3.
Furthermore, the oil penetration holes arranged on the raceway surface of the bearing outer ring are uniformly distributed with a plurality of groups (the number of the groups is determined according to the size of the bearing) at intervals along the raceway surface, each group is 2-4, and the oil penetration holes of each group are uniformly distributed at intervals along the axial direction.
Still more specifically, the diameter of the oil penetration hole is 1 to 3 mm.
The utility model has the advantages that: through reasonable, ingenious and simple design, the long cylindrical roller bearing capable of automatically supplementing oil for lubrication for a long time can automatically keep high-efficiency lubrication performance for a long time in the running and using process, the running performance and the efficiency can be fully exerted, the frequency of oil filling maintenance of the bearing is greatly reduced, labor and time are saved, and the production operation efficiency is improved.

Detailed Description
A long cylindrical roller bearing capable of automatically supplementing oil and lubricating for a long time 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, the bearing outer ring 1 is a hollow structure body, an oil filling hole 1-1 communicated with an inner cavity of the bearing outer ring 1 is arranged on the outer circumferential surface of the bearing outer ring 1 and is provided with a matched sealing plug, oil seepage holes 1-2 communicated with the inner cavity of the bearing outer ring 1 are arranged on the roller path surface of the bearing outer ring 1, and lubricating oil 5 is stored in the inner cavity of the bearing outer ring 1.
The oil seepage holes 1-2 arranged on the raceway surface of the bearing outer ring 1 are uniformly distributed with a plurality of groups (the number of the groups is determined according to the size of the bearing) at intervals along the raceway surface, each group is 2-4, and the oil seepage holes 1-2 of each group are uniformly distributed at intervals along the axial direction. The aperture of the oil penetration hole 1-2 is 1-3 mm.
In the running and using process of the bearing, lubricating oil 5 which is injected into the inner cavity of the bearing outer ring 1 in advance slowly enters the raceway through the oil penetration holes 1-2 for a long time, continuously lubricates the rotating long cylindrical roller 3, and forms an oil film on the raceway surface and the surface of the long cylindrical roller 3.
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.
