Abstract
The utility model belongs to the technical field of a bearing retainer, which provides a retainer structure which improves the lubricating condition of a bearing. A convex ring-shaped oil blocking lug boss (2) is arranged on the inner diametral plane of a retainer (1). The utility model has the advantages of peculiar concept and simple structure. As a consequence that the inner diametral plane of the retainer is provided with the ring-shaped oil blocking lug boss which performs blocking action on lubricating oil flowing toward an end face, the lubricating oil flows to a roller and a cage pocket of the retainer under the action of a centrifugal force to form an enclosed lubricating-zone with a sleeve ring, the lubricating condition of the lubricating mode that the bearing supplies oil under a ring is improved, and the service performance and the service life of the bear are enhanced.
Description
Affiliated technical field
The utility model belongs to the retainer technical field, and what relate generally to is a kind of retainer structure of improving the bearing lubrication condition.
Background technique
The quality of rolling bearing lubricating condition directly influences the working life of bearing, and especially for the rolling bearing that uses under high temperature, high-speed working condition, lubricating condition has become influences the bearing deciding factor in working life.For this class bearing, lubricating system commonly used is jet lubrication, at the bearing two ends one or two injection loop is arranged usually, has nozzle opening on the injection loop, and nozzle opening is aimed at the slit between retainer and the lasso.Injection loop rotates with axle, and lubricant oil carries out jet lubrication by centrifugal force.Because the slit between retainer and the inner ring has part to be stopped by roller, so lubricant oil can not enter bearing inside fully, cause the lubricant oil supply not smooth, cause insufficient lubrication, simultaneously since lubricant oil without bearing inner race, the heat that inner ring produces can not be taken away by lubricated in time oil, causes the bearing working temperature higher.
Fuel feeding is lubricated under the ring is considered to efficient at present than one of higher lubricating system, and its method is to bore several oilholes at bearing inner race, and lubricant oil relends and helps centrifugal force to enter in the bearing bore from oilhole by the cavity arrival oilhole of oil-collecting device from axle.The advantage of this lubricating system is obvious, when improving the lubricating status of bearing, because of lubricant oil contact bearing inner ring at first, can reduce the Internal and external cycle temperature difference, and cooling effect is also better.Common ring lubricates down dual mode, a kind of is along the circumferential direction evenly to bore several oilholes at inner ring two row oil duct places, its advantage is that lubricant oil can all enter bearing inside, lubrication effect is better, shortcoming is that oilhole is near the bearing load district, reduced the intensity of bearing, and the oilhole place cracks easily.Another kind of mode is in the boring of inner ring outer radius, because oilhole is away from the bearing load district, the intensity not influence basically to bearing also is difficult for cracking, and is fit to some special construction bearings and adopts.But, because of lubricant oil not by the oil duct place, parts of lubricating oil flows out from end face, can not enter bearing bore, lubricating system has been compared certain gap under its lubrication effect and the first kind of ring.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of retainer structure of improving the bearing lubrication condition, and oil feeding mechanism is used and can effectively improves the lubricating condition of bearing under fuel feeding lubricating system under the ring under this retainer and the ring.
For achieving the above object, the technological scheme taked of the utility model is: at the oily boss of the lobed annular retaining of retainer aperture surface.
The utility model design is unique, simple in structure.Because the aperture surface of retainer has the retaining oil boss of annular, this keeps off oily boss the lubricant oil that flows to end face is played barrier effect, like this, lubricant oil flows to roller and retainer pocket hole under action of centrifugal force, make it to form the lubricated district of enclosed with lasso, effectively improved the lubricating condition of bearing under fuel feeding lubricating system under the ring, the usability and the working life of having improved bearing.
Description of drawings
Accompanying drawing 1 is the utility model stereogram.
Accompanying drawing 2 is the utility model structural representation.
Accompanying drawing 3 is the utility model user mode schematic representation.
Among the figure, 1, retainer, 2, keep off oily boss, 3, the pocket hole, 4, the outer ring, 5, rolling element, 6, inner ring.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
, have to the annular of outer lug at rolling bearing retainer 1 aperture surface and to keep off oily boss 2 in conjunction with shown in Figure 2 as Fig. 1, this annular is kept off the end face of oily boss 2 near aperture surfaces, can be an end setting, bestly is the two ends settings.Its height that keeps off oily boss 2 can be determined according to factors such as bearing structure, rotating speed, operating temperature, flow of lubrication, lubricating oil types, usually between 0.2mm-1mm.Present embodiment is when assembling (as shown in Figure 3), and rolling element 5 places retainer 1, pocket hole 3, and inner ring 6 raceways composition inner ring---rolling element---the retainer assembly of packing into, and outer ring 4 raceways of packing into then are assembled into bearing.The oily boss of this retaining plays barrier effect to the lubricant oil that flows to end face during use, makes lubricant oil flow to roller and retainer pocket hole under action of centrifugal force, makes it to form the lubricated district of enclosed with lasso.
Claims (3)
1, a kind of retainer structure of improving the bearing lubrication condition is characterized in that: the lobed annular retaining of the aperture surface of described retainer (1) oily boss (2).
2, the retainer structure of improving the bearing lubrication condition according to claim 1, it is characterized in that: the oily boss of described retaining (2) is positioned at the two ends of retainer aperture surface.
3, the retainer structure of improving the bearing lubrication condition according to claim 1 and 2, it is characterized in that: the height of the oily boss of described retaining (2) is 0.2mm-1mm.
