Description
Technical Field
The utility model belongs to the technical field of the bearing manufacturing technique and specifically relates to a full complement long cylindrical roller bearing of high dustproof and sealing performance is related to.
Background
The cylindrical roller bearing is a centripetal rolling bearing with cylindrical rollers as rolling bodies, the cylindrical rollers are in line contact with the roller paths, the radial load capacity is high, and the cylindrical roller bearing is suitable for bearing heavy loads and impact loads and is also suitable for high-speed rotation. The full-complement cylindrical roller bearing is different from a common cylindrical roller bearing, the bearing has no retainer, the cylindrical rollers are assembled in a full complement mode and can contain more rollers, and compared with a non-full-complement cylindrical roller bearing with the same size, the bearing can bear larger radial load, is small in radial section and can save space, so that the bearing product is widely applied to occasions with low speed and heavy load. At present, a full-complement cylindrical roller bearing is generally an open roller bearing, namely an open structure, and because the full-complement cylindrical roller bearing is exposed in the air for a long time, especially in a severe occasion, lubricating oil injected into an inner cavity of the open roller bearing is easy to run off, and the lubricating oil is often corroded by external dust, impurities and the like, so that the friction of a roller is increased, the resistance and the noise are increased, even the roller is stuck and scrapped, and the service life is greatly shortened.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the full complement long cylindrical roller bearing with high dustproof and sealing 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: the long cylindrical roller bearing with high dustproof and sealing performance comprises a bearing outer ring, a bearing inner ring and long cylindrical rollers, wherein the long cylindrical rollers are assembled in a raceway formed by corresponding raceway surfaces of the bearing outer ring and the bearing inner ring in a full-filling mode, roller flanges are formed on two axial sides of the raceway surface of the bearing outer ring, dustproof sealing check rings are arranged between the roller flanges of the bearing outer ring and the axial side surface of the bearing inner ring at the same side, the dustproof sealing check rings are fixedly connected with the axial side surface of the bearing inner ring, the dustproof sealing check rings are in clearance fit with the roller flanges of the bearing outer ring, and sealing rings embedded in prefabricated grooves of the dustproof sealing check rings are arranged between the dustproof sealing check rings and the roller flanges of the bearing outer ring. The existence of dustproof sealing check ring can well obstruct external dust and impurities effectively, prevent the external dust and impurities from entering the bearing raceway, and the clearance between the dustproof sealing check ring and the bearing outer ring is compensated by the sealing ring embedded in the prefabricated groove of the dustproof sealing check ring, so that the inner cavity of the bearing is protected perfectly.
Furthermore, in order to reduce the contact friction area between the dustproof sealing check ring and the long cylindrical roller in the raceway, clearance fit exists between the dustproof sealing check ring and the long cylindrical roller in the raceway.
Still further, the sealing washer be the spring sealing washer, the spring sealing washer is commonly used on the market, a sealing washer that constitutes by the sealing washer body with the spring combination. And a spring sealing ring is adopted, so that the sealing effect is better.
The utility model has the advantages that: through reasonable, ingenious and simple design, the fully-packed long cylindrical roller bearing with high dustproof and sealing performance realizes excellent dustproof and sealing performance, the quality and the service life of a product are remarkably improved, and the use requirement is met.

Detailed Description
A full complement long cylindrical roller bearing with high dustproof and sealing performance is disclosed, as shown in figure 1, and comprises a bearing outer ring 1, a bearing inner ring 2 and long cylindrical rollers 3, wherein the long cylindrical rollers 3 are assembled in a full complement mode in a raceway formed by corresponding raceway surfaces of the bearing outer ring 1 and the bearing inner ring 2, roller flanges are formed on two axial sides of the raceway surface of the bearing outer ring 1, a dustproof sealing check ring 4 is arranged between the roller flange of the bearing outer ring 1 and the axial side surface of the bearing inner ring 2 on the same side, the dustproof sealing check ring 4 is fixedly connected with the axial side surface of the bearing inner ring 2, the dustproof sealing check ring 4 is in clearance fit with the roller flange of the bearing outer ring 1, and a sealing ring 5 embedded in a prefabricated groove of the dustproof sealing check ring 4 is arranged between the dustproof sealing roller check ring 4 and the flange of the bearing outer ring 1. The existence of the dustproof sealing check ring 4 can well and effectively block external dust and impurities to prevent the external dust and impurities from entering a bearing raceway, and a gap between the dustproof sealing check ring 4 and the bearing outer ring 1 is compensated by the sealing ring 5 embedded in the prefabricated groove of the dustproof sealing check ring 4, so that the inner cavity of the bearing is perfectly protected.
Clearance fit exists between the dustproof sealing check ring 4 and the long cylindrical roller 3 in the raceway so as to reduce the contact friction area between the dustproof sealing check ring 4 and the long cylindrical roller 3 in the raceway.
The sealing ring 5 is a spring sealing ring which is commonly used in the market and is formed by combining a sealing ring body and a spring. And a spring sealing ring is adopted, so that the sealing effect is better.
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.
