Abstract
The utility model discloses a kind of enhanced four-row cylindrical roller bearing, two retainers including bearing inner race, being socketed on bearing inner race and the bearing outer ring of two retainers of socket, two retainers are respectively equipped with the first roller and the second roller.If bearing outer ring is provided with dry lube hand-hole, the inwall of bearing outer ring and the joint place of the first roller, the second roller are provided with oil storage passage, and lubricating oil hand-hole runs through bearing outer ring and oil storage channel connection.Injecting lubricating oil by lubricating oil hand-hole, lubricating oil enters oil storage passage, during roller rotates, bearing is carried out sufficient lubrication, is greatly reduced frictional force, reduces friction level during bearing high-speed rotation, extend the service life of bearing.The inner surface of bearing outer ring is provided with the first groove, and the outer surface of bearing inner race is provided with in the second groove, the first groove and the second groove and to be connected with sealing lid, the effective guarantee sealing of bearing.
Description
Technical field
This utility model relates to a kind of bearing, particularly relates to a kind of enhanced four-row cylindrical roller bearing.
Background technology
In plant equipment, bearing is widely used, and the use environment of some plant equipment is relatively more severe, chip, ash
Dirt is the most, and these impurity likely drop in bearing, affects the normal operation of bearing, and serious also can destroy bearing,
Cause whole device damage eventually.Therefore bearing is lubricated and seals and be just particularly important.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of enhanced four-row proposed
Cylinder roller bearing.
To achieve these goals, this utility model adopts the technical scheme that
A kind of enhanced four-row cylindrical roller bearing, protects including bearing inner race, two bearings being socketed on bearing inner race
Hold frame and the bearing outer ring of two retainers of socket, two retainers are respectively equipped with the first roller and the second rolling
Son, if described bearing outer ring is provided with dry lube hand-hole, the inwall of bearing outer ring and the first roller, the laminating of the second roller
Place is provided with oil storage passage, and lubricating oil hand-hole runs through bearing outer ring and oil storage channel connection；
The inner surface of described bearing outer ring is provided with the first groove, and the outer surface of described bearing inner race is provided with the second groove,
First groove and the second groove are connected with sealing lid.
Preferably, it is provided with sealing ring in described first groove.
Preferably, the described lid that seals is positioned at one end of the second groove and is provided with diaphragm seal, and the end abutment of diaphragm seal is the
In two grooves.
Compared with prior art, the beneficial effects of the utility model are:
1, in routine use, injecting lubricating oil by lubricating oil hand-hole, lubricating oil enters oil storage passage, turns at roller
During Dong, bearing outer ring inner wall surface, retainer surface, roller surface and bearing inner race outer wall surface are distributed with
Lubricating oil and being all fully contacted with lubricating oil, it is ensured that between roller and bearing outer ring inwall, roller and bearing inner race outer wall it
Between the content of lubricating oil, be greatly reduced frictional force, reduce friction level during bearing high-speed rotation, improve and keep bearing
Lubricant effect, it is achieved running up of bearing, extends the service life of bearing.
2, the inner surface of bearing outer ring is provided with the first groove, is provided with sealing ring in the first groove, the outer surface of bearing inner race
Being provided with in the second groove, the first groove and the second groove and be connected with sealing lid, sealing lid is positioned at one end of the second groove and sets
Having diaphragm seal, the end abutment of diaphragm seal is in the second groove.Coordinated with the common of diaphragm seal by sealing ring, effective guarantee
The sealing of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of enhanced four-row cylindrical roller bearing that the utility model proposes；
Fig. 2 is the enlarged drawing in Fig. 1 at A.
In figure: 1, bearing outer ring, 2, bearing inner race, 3, retainer, the 4, first roller, the 5, second roller, 6, lubrication
Oil hand-hole, 7, oil storage passage, the 8, first groove, the 9, second groove, 10, sealing ring, 11, diaphragm seal, 12, seal lid.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of enhanced four-row cylindrical roller bearing, including bearing inner race 2, it is socketed on bearing inner race 2
Two retainers 3 and socket two retainers 3 bearing outer ring 1, two retainers 3 are respectively equipped with
First roller 4 and the second roller 5.If described bearing outer ring 1 is provided with dry lube hand-hole 6, the inwall of bearing outer ring 1 and
The joint place of one roller the 4, second roller 5 is provided with oil storage passage 7, and lubricating oil hand-hole 6 runs through bearing outer ring 1 and oil storage passage 7
Connection.In routine use, can inject lubricating oil by lubricating oil hand-hole 6, lubricating oil enters oil storage passage 7, at roller
During rotation, bearing outer ring 1 inner wall surface, retainer 3 surface, roller surface and bearing inner race 2 outer wall surface are equal
Lubricating oil is distributed and is all fully contacted with lubricating oil, it is ensured that between roller and bearing outer ring 1 inwall, roller and bearing inner race
Between 2 outer walls, the content of lubricating oil, is greatly reduced frictional force, reduces friction level during bearing high-speed rotation, improves and protects
Hold the lubricant effect of bearing, it is achieved running up of bearing, extend the service life of bearing.
The inner surface of described bearing outer ring 1 is provided with the first groove 8, is provided with sealing ring 10, in described bearing in the first groove 8
The outer surface of circle is provided with the second groove 9, is connected with sealing lid 12 in the first groove 8 and the second groove 9, seals lid 12 and is positioned at the
One end in two grooves 9 is provided with diaphragm seal 11, and the end abutment of diaphragm seal 11 is in the second groove 9.By sealing ring 10 with close
The common cooperation of mounting 11, the effective guarantee sealing of bearing.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art is in the technical scope that this utility model discloses, according to this practicality
Novel technical scheme and utility model thereof conceive equivalent or change in addition, all should contain at protection model of the present utility model
