Abstract
The utility model discloses a kind of roller bearing outer ring, comprise outer ring body, on the end face of the both sides of outer ring body, be provided with annular rib, on the inwall of outer ring body, be provided with for holding the ring raceway of cylindrical roller, along the circumferential direction uniformly in upper half part of ring raceway be provided with some oil storage tanks that are connected, between adjacent oil storage tank, form one for holding the gap of cylindrical roller, on the sidewall of oil storage tank, offer some through holes, the top of the exterior arc surface of described outer ring body offers oil hole radially, and oil hole is connected with oil storage tank.The utility model will be established an oil storage tank in the raceway of outer ring body, and on oil storage tank, offer through hole, on the one hand can be when assembling bearing, in oil storage tank, store lubricant oil, so just can make bearing in when work, lubricant oil flows out in along through hole from oil storage tank, to playing lubrication between each parts of bearing inside, reduce loss, improved the working life of bearing.
Description
Technical field
The utility model belongs to technical field of bearings, relates in particular to a kind of roller bearing outer ring.
Background technique
As everyone knows, bearing is comprised of outer ring, inner ring, retainer and rolling element, and a key factor that affects bearing working life is frictional loss.Friction between friction between friction between rolling element and Internal and external cycle, rolling element and retainer and inner ring and axle etc., these frictions all can loss bearing whole service life, existing remission method is by add lubricant oil, lubricating grease etc. in bearing, but the equipped sealing between each parts of bearing is higher, therefore, lubricating oil filling or lubricating grease enter bearing the inside, difficulty comparatively, and easily by entering into lubricant oil, lubricating grease in bearing, do not drip to and on ground, cause waste.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of roller bearing outer ring, the bearing that is fitted with this outer ring does not need its lubricating oil filling, lubricating grease etc. to be lubricated in the course of the work, this bearing can lubricating by oneself, greatly improve the working life of bearing, saved manpower labour.
For achieving the above object, the utility model adopts following technological scheme:
A kind of roller bearing outer ring, comprise outer ring body, on the end face of the both sides of outer ring body, be provided with annular rib, on the inwall of outer ring body, be provided with for holding the ring raceway of cylindrical roller, along the circumferential direction uniformly in upper half part of ring raceway be provided with some oil storage tanks that are connected, between adjacent oil storage tank, form one for holding the gap of cylindrical roller, on the sidewall of oil storage tank, offer some through holes, the top of the exterior arc surface of described outer ring body offers oil hole radially, and oil hole is connected with oil storage tank.
Further, the outer surface of described oil storage tank is cylindrical surface structure.
Owing to adopting technological scheme as above, the utlity model has following superiority:
The utility model will be established an oil storage tank in the raceway of outer ring body, and on oil storage tank, offer through hole, on the one hand can be when assembling bearing, in oil storage tank, store lubricant oil, so just can make bearing in when work, lubricant oil flows out in along through hole from oil storage tank, to playing lubrication between each parts of bearing inside, reduce loss, improved the working life of bearing; On the other hand, after this outer ring and bearing support are equipped, on bearing support, offer the tank filler sleeve corresponding with oil hole, can be at any time to adding lubricant oil in the oil storage tank on outer ring, and then lubricating bearings, easy to operate, high lubricating effect, has effectively extended working life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In Fig. 1: the body of 1-outer ring; 2-annular rib; 3-oil storage tank.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of roller bearing outer ring, comprise outer ring body, on the end face of the both sides of outer ring body, be provided with annular rib, on the inwall of outer ring body, be provided with for holding the ring raceway of cylindrical roller, along the circumferential direction uniformly in upper half part of ring raceway be provided with some oil storage tanks that are connected, between adjacent oil storage tank, form one for holding the gap of cylindrical roller, on the sidewall of oil storage tank, offer some through holes, the top of the exterior arc surface of described outer ring body offers oil hole radially, and oil hole is connected with oil storage tank.
When assembling bearing, in the gap of cylindrical roller between adjacent oil storage tank, and in order to reduce friction, the outer surface of oil storage tank can be made as to cylindrical surface structure, making between cylindrical roller and oil storage tank is tangent surface of contact; By the oil hole on the body of outer ring, in oil storage tank, inject lubricant oil, during work, rotation along with cylindrical roller, the lubricant oil flowing out in through hole from oil storage tank is for the friction between lubricated roller and inside and outside circle and retainer, greatly reduce frictional heating, effectively extended the whole service life of bearing.
In addition, when being fitted with the bearing of this bearing outer ring and bearing support and installing, on bearing support, offer a tank filler sleeve corresponding with described oil hole, or between tank filler sleeve and oil hole, through hole one oil filling pipe is communicated with, bearing in the course of the work, can be at any time adds lubricant oil, to reduce the frictional heating of each parts in bearing in the oil storage tank on bearing outer ring, extend the working life of bearing, guaranteed the safe operation of equipment.
The outer surface of described oil storage tank is cylindrical surface structure.
Claims (2)
1. a roller bearing outer ring, comprise outer ring body (1), on the end face of the both sides of outer ring body, be provided with annular rib (2), on the inwall of outer ring body, be provided with for holding the ring raceway of cylindrical roller, it is characterized in that: uniform some oil storage tanks that are connected (3) that are provided with along the circumferential direction in upper half part of ring raceway, between adjacent oil storage tank, form one for holding the gap of cylindrical roller, on the sidewall of oil storage tank, offer some through holes, the top of the exterior arc surface of described outer ring body offers oil hole radially, and oil hole is connected with oil storage tank.
