Abstract
The utility model relates to a bearing structure for preventing oil leakage at an inner ring. The bearing structure comprises a first sealing ring, rollers, a retaining frame, an inner ring and an outer ring, wherein the retaining frame is placed between the inner ring and the outer ring, the first sealing ring is used for sealing between the inner ring and the outer ring, and the rollers which are distributed symmetrically are placed on the retaining frame; a sealing slot is formed in a chamfer angle of the inner ring, and a second sealing ring is placed on the sealing slot; the transition of static pressure contact sealing between round angles is realized through the second sealing ring and a matching shaft. The bearing structure provided by the utility model has the beneficial effects that by additionally arranging the second sealing ring on the inner ring, the oil leakage phenomenon of an oil supply system at the inner ring is solved, and the risk of causing brake failure of a wheel side system due to oil leakage at the inner ring is avoided.
Description
Technical field
The utility model relates to field of bearings, is mainly the bearing structure of a kind of anti-inner ring place oil impregnate.
Background technique
Bearing is widely used in all kinds of gearing systems, but its running must have good oil feeding mechanism and lubrication system, occurs that oil impregnate or leakage of oil meeting reduce lifetime of system.
At present, be applied to mechanical middle (center) bearing, from designing as making bearing dismantling convenient, on the diameter of axle coordinates, generally adopt Spielpassung, and oil supply system can be oozed out from coordinate.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of bearing structure that can improve the anti-inner ring place oil impregnate in working life is provided.
The purpose of this utility model completes by following technical solution, it comprises the first seal ring, roller, retainer, inner ring and outer ring, between described inner ring and outer ring, be placed with retainer, and between this inner ring and outer ring, by the first seal ring, sealed, on this retainer, be placed with the roller being symmetric.
As preferably, the chamfering place of described inner ring is provided with seal groove, is placed with the second seal ring on sealing groove; By static pressure between this second seal ring and fitted shaft knuckle, contact sealing.
The beneficial effects of the utility model are: by set up the second seal ring on inner ring, thereby solve oil supply system oil leakage phenomenon herein, and avoid taking turns edge system and cause the danger of brake failure because of oil impregnate herein.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model cooperating structure schematic diagram in actual applications.
Label in accompanying drawing is respectively: 1, the first seal ring; 2, roller; 3, retainer; 4, inner ring; 5, outer ring; 6, the second seal ring; 7, fitted shaft knuckle; 41, seal groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in accompanying drawing 1,2, the utility model comprises the first seal ring 1, roller 2, retainer 3, inner ring 4 and outer ring 5,5 of described inner ring 4 and outer rings are placed with retainer 3, and 5 of this inner ring 4 and outer rings are sealed by the first seal ring 1, are placed with the roller 2 being symmetric on this retainer 3.The chamfering place of described inner ring 4 is provided with seal groove 41, is placed with the second seal ring 6 on sealing groove 41; By 7 static pressure of this second seal ring 6 and fitted shaft knuckle, contact sealing.
The utility model is by designing seal groove 41 to inner ring chamfering place, double row bearing one end, increase by the second seal ring 6 structures, by 7 static pressure of the second seal ring 6 and fitted shaft knuckle, contact sealing, solve oil supply system oil leakage phenomenon herein, and avoid taking turns edge system and cause the danger of brake failure because of oil impregnate herein.
The utility model is not limited to above-mentioned mode of execution; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model, is all a kind of distortion of the present utility model, all should think within the utility model protection domain.
