Abstract
The utility model relates to a high-load sealing cylindrical roller bearing, which comprises an outer ring, an inner ring, a cylindrical roller and a sealing ring, and is characterized in that the high-load sealing cylindrical roller bearing also comprises a check ring and a connecting strut; a plurality of equidistant mounting holes are formed in the retainer ring, and a plurality of equidistant supporting bulges are arranged between the adjacent mounting holes on the side surface of the retainer ring; two sides of the cylindrical roller are respectively provided with a supporting groove; the inner side of the outer ring is provided with a roller groove; the two retaining rings are fixedly connected with the mounting holes through the connecting support columns and then sleeved on the outer sides of the inner rings, and the outer ring sleeves are sleeved on the outer sides of the two retaining rings through the roller grooves; the supporting bulges on the two retaining rings are correspondingly positioned between the two retaining rings, the cylindrical rollers are arranged on the two retaining rings in a rolling manner through the supporting grooves and the corresponding supporting bulges on the retaining rings, and a sealing ring is respectively arranged between the outer ring and the inner ring at two sides of the two retaining rings. The utility model has the advantages of wear-resisting damage and service life prolonging.
Description
Technical Field
The utility model relates to a roller bearing especially relates to a high load seals cylindrical roller bearing.
Background
The cylindrical roller bearing used in the current engineering machinery preparation comprises an outer ring, an inner ring, a cylindrical roller, a sealing ring, a retainer and a retainer cover; the inner side of the outer ring is provided with a roller groove; the retainer is arranged in a roller groove of the outer ring, a plurality of roller through holes are arranged on the retainer, cylindrical rollers are arranged in the roller through holes, and retainer covers are respectively arranged on two sides of the retainer; a sealing ring is arranged on the outer side of the retainer cover; the inner ring is arranged in the retainer; because the cylindrical rollers are arranged on the integral retainer, a partition is arranged between every two adjacent cylindrical rollers, and because the cylindrical roller bearing used in the engineering machinery preparation has a large load in the working process, in order to enable the retainer to have an effective supporting effect on the cylindrical rollers, the partition between every two adjacent cylindrical rollers needs a certain thickness, the number of the cylindrical rollers arranged on the retainer is limited to a certain extent, so that the cylindrical roller bearing is easy to wear when working on the engineering machinery preparation, and is easy to damage in a high-load working environment.
Disclosure of Invention
To the shortcoming above, an object of the utility model is to provide a wear-resisting high load sealing cylindrical roller bearing who decreases and can improve life.
The technical content of the utility model is that a high-load sealing cylindrical roller bearing, which comprises an outer ring, an inner ring, a cylindrical roller and a sealing ring, and is characterized in that the bearing also comprises a retaining ring and a connecting strut; a plurality of equidistant mounting holes are formed in the retainer ring, and a plurality of equidistant supporting bulges are arranged between the adjacent mounting holes on the side surface of the retainer ring; two sides of the cylindrical roller are respectively provided with a supporting groove; the inner side of the outer ring is provided with a roller groove; the two retaining rings are fixedly connected with the mounting holes through the connecting support columns and then sleeved on the outer sides of the inner rings, and the outer ring sleeves are sleeved on the outer sides of the two retaining rings through the roller grooves; the supporting bulges on the two retaining rings are correspondingly positioned between the two retaining rings, the cylindrical rollers are arranged on the two retaining rings in a rolling manner through the supporting grooves and the corresponding supporting bulges on the retaining rings, and a sealing ring is respectively arranged between the outer ring and the inner ring at two sides of the two retaining rings.
Compared with the prior art, the utility model the advantage that has do: the utility model discloses a set up cylindrical roller between two retainer rings for interval between the cylindrical roller between the two adjacent connecting support columns diminishes, thereby improved cylindrical roller's installation quantity, made its during operation difficult wearing and tearing on engineering machine tool preparation from this, especially more wear-resisting in the operational environment of high load, thereby improved life.
