Abstract
The utility model relates to a bearing with a novel seal ring, which comprises an inner ring, an outer ring and a dust-proof groove arranged between the inner ring and the outer ring, wherein a seal ring is arranged in the dust-proof groove and comprises a seal ring body; and an outward-extending annular first lip is arranged on the outer edge of the seal ring body, and inward-extending annular second and third lips are arranged on the inner edge of the seal ring body. The three lips on the seal ring, namely the first lip on the outer edge of the seal ring body and the second and the third lips on the inner edge of the seal ring body, can effectively prevent lubricating grease externally from leaking or internally permeating, and have better dust-proof function.
Description
(1) technical field
The utility model relates to a kind of bearing sealed ring.
(2) background technique
Bearing is easier to enter bearing inside or past outside leakage of bearing internal lubrication fat at high speed (30000rpm) operation process middle (center) bearing external lubrication fat ratio, bearing lost efficacy in the process middle (center) bearing sealability that runs up in addition, caused external dust to enter bearing inside and caused damage of bearings.As shown in Figure 1, available technology adopting has the seal ring of a lip and bilabiate structure, and (below the 20000rpm) can prevent oil leakage at low speed, but said structure is difficult to guarantee bearing seal performance and leakproof fat performance in the process that runs up for a long time.
(3) summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of can solve bearing prevents the past outside leakage of bearing internal grease and its sealability of bearing length time running back assurance in operation process bearing.
The technical scheme in the invention for solving the technical problem is:
A kind of bearing with novel seal circle, comprise inner ring, outer ring and be arranged on inner ring and the outer ring between dustproof groove, be provided with seal ring in the described dustproof groove, seal ring comprises the seal ring body, described seal ring body outward edge is provided with outwardly directed ring-type first lip, and described seal ring body inward flange is provided with ring-type second lip and the 3rd lip that inwardly stretches out.
As improvement, in the two ends of dustproof groove lay respectively on the ring outer wall with the outer ring inwall on, the outer surface of described first lip and inner ring corresponding position is an interference fit, the outer surface of described the 3rd lip and inner ring corresponding position is a Spielpassung, and the inner side surface of described second lip and interior collar dustproof groove is a transition fit.
As preferably, the upper side of first lip, second lip and the 3rd lip is domatic.
Three lips are set on seal ring, promptly at the outward edge of seal ring body first lip are set respectively, second lip and the 3rd lip are set at the inward flange of seal ring body.First lip and inner ring outer surface interference fit, can prevent that external lubrication fat from infiltrating bearing inside because of being subjected to foreign impacts power, have protective action and dustproof effect, the 3rd lip and inner ring outer surface Spielpassung, the lubricating grease that can effectively control bearing inside can carry out water conservancy diversion smoothly with it when being thrown on the seal ring, the inner side surface transition fit of second lip and dustproof groove, promptly possible interference fit is the possibility Spielpassung also, if lubricating grease is broken through first lip and second lip, then under the effect of extraneous impact force and bearing internal pressure, produce an interaction force and make second lip crowded more tight more, avoid external dust to enter into bearing inside.The upper side of first lip, second lip and the 3rd lip is domatic, lubricating grease can be carried out effective water conservancy diversion.
The beneficial effects of the utility model are: the utility model is provided with three lips on seal ring, outward edge at the seal ring body is provided with first lip respectively, inward flange at the seal ring body is provided with second lip and the 3rd lip, can effectively avoid lubricating grease to leak outside or infiltrate, have dustproof effect preferably simultaneously.
(4) description of drawings
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is the structural representation of seal ring of the present utility model;
Fig. 3 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Shown in Fig. 2,3, a kind of bearing with novel seal circle, comprise inner ring 6, outer ring 5 and be arranged on inner ring and the outer ring between dustproof groove 7, in the two ends of dustproof groove lay respectively on the ring outer wall with the outer ring inwall on, be provided with seal ring 1 in the dustproof groove 7, seal ring 1 comprises the seal ring body.Seal ring body outward edge is provided with outwardly directed ring-type first lip 2, and seal ring body inward flange is provided with ring-type second lip 3 that inwardly stretches out and the upper side of the 3rd lip 4, the first lips 2, second lip 3 and the 3rd lip 4 is domatic.The outer surface of first lip and inner ring corresponding position is an interference fit, and the outer surface of the 3rd lip and inner ring corresponding position is a Spielpassung, and the inner side surface of second lip and interior collar dustproof groove is a transition fit.
Claims (3)
1. bearing with novel seal circle, comprise inner ring, outer ring and be arranged on inner ring and the outer ring between dustproof groove, be provided with seal ring in the described dustproof groove, seal ring comprises the seal ring body, it is characterized in that: described seal ring body outward edge is provided with outwardly directed ring-type first lip, and described seal ring body inward flange is provided with ring-type second lip and the 3rd lip that inwardly stretches out.
2. the bearing with novel seal circle according to claim 1, it is characterized in that: in the two ends of described dustproof groove lay respectively on the ring outer wall with the outer ring inwall on, the outer surface of described first lip and inner ring corresponding position is an interference fit, the outer surface of described the 3rd lip and inner ring corresponding position is a Spielpassung, and the inner side surface of described second lip and interior collar dustproof groove is a transition fit.
