Abstract
The utility model discloses a narrow flange sealing bearing fully provided with rollers in the mechanical equipment field. The narrow flange sealing bearing fully provided with the rollers comprises an external ring, an internal ring, a cylindrical roller and sealing rings; the cylindrical roller is arranged between rolling channels of the external ring and the internal ring; the sealing rings are arranged on end surfaces on bilateral sides of the bearing. The narrow flange sealing bearing fully provided with the rollers is characterized in that the internal side on the end surface on the axial side is provided with a flat stopping ring; the stopping ring is arranged between an end surface of the cylindrical roller and the sealing rings; the flat stopping ring is in sliding contact with the end surface of the cylindrical roller; the external side of the sealing ring is provided with an axial stopping ring; the flat stopping ring is made of high hardness materials; the wear resistant performance of the flat stopping ring is equal to or higher than the cylindrical roller. The narrow flange sealing bearing fully provided with the rollers has the advantages of being long in service life, strong in axial force bearing performance and the like.
Description
Technical field
The utility model relates to a kind of narrow rib stuffing box bearing that completely fills roller in machinery field.
Background technique
At machinery middle (center) bearing, be conventional rotary connecting device, bearing has various bearing types because of use occasion and stressed difference, and roller bearing is exactly a kind of bearing type wherein, and roller bearing is mainly used in the load of radial force.
Between the roller surface of roller bearing and the rolling surface of roller, easy generation slided, and roller can produce axial float in raceway, and existence cannot fully suppress the problem of wearing and wearing away.
Summary of the invention
The purpose of the present utility model overcome prior art in because the axial float of roller bearing causes the wearing and tearing of seal ring, thereby affect the defect in the working life of bearing, a kind of narrow rib stuffing box bearing that can bear the full dress roller of axially loaded is provided.
The present utility model is achieved through the following technical solutions:
A kind of narrow rib stuffing box bearing that completely fills roller, comprise outer ring, inner ring, cylindrical roller and seal ring, cylindrical roller is positioned between the raceway of outer ring and inner ring, seal ring is arranged at bearing both sides end face, it is characterized in that: an axial side end face inner side is provided with loose rib, loose rib between cylindrical roller end face and seal ring, the end face sliding contact of loose rib and cylindrical roller, seal ring outside be shaft block ring, and that inner side increase loose rib has been realized is spacing, sealing and axial strength; Technique scheme is done to further improvement, and described loose rib is high-hardness, and its wear-resisting property is equal or higher than cylindrical roller, has improved the working life of bearing.
The utlity model has following technical characterstic:
1. long service life;
2. bear axial force strong.
Accompanying drawing explanation
Fig. 1 is for completely filling the narrow rib sealed bearing structure schematic diagram of roller.
In figure: outer ring 1, inner ring 2, cylindrical roller 3, seal ring 4, loose rib 5 and shaft block ring 6.
Embodiment
Explanation below in conjunction with Figure of description to the nearest step of content of the present utility model:
For completely to fill the narrow rib sealed bearing structure schematic diagram of roller, comprise outer ring 1, inner ring 2, cylindrical roller 3, seal ring 4, loose rib 5 and shaft block ring 6 as described in Figure.Completely fill the sliding damper limit with the seal ring design of roller bearing, adopt seal ring and the same installing space Position Design of shaft block ring, inner side increases by a loose rib, realizes spacing, sealing and axial loose rib wear-resisting.
The loose rib of inner side design for high hardness material, keeps and wear-resisting life requirements that bearing roller is equal, and intermediate seal circle has been realized the seal request to bearing, and outermost shaft block ring has been realized spacing to full dress Roller Shaft.
Claims (2)
