Abstract
The utility model discloses a sealing ring of a bearing. The sealing ring comprises a rubber elastic body and a steel frame; a groove is formed at the upper end of the rubber elastic body; an arc-shaped lip and a straight lip are formed at the lower end of the rubber elastic body; a cavity is defined by the arc-shaped lip and the straight lip; and oil is filled in the cavity. The semi-circular groove is arranged at the upper end of the rubber elastic body, so that the sealing ring of the bearing is convenient to install and fits closely; and the oil is filled in the cavity, so that tiny dust and impurities are prevented from permeating into the bearing, the sealing performance is good, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of seal ring, especially a kind of bearing sealed ring.
Background technique
On the axle of seal container, in order to prevent the seepage of oils medium, bearing seal is installed all on axle at present, to obtain efficient sealing effect.The existing bearing seal ring is made by being wrapped in the outer rubber material of a Steel Skeleton usually, drive fit by back formation in the groove that the outer caulking gum of seal ring is embedded bearing outer ring, the internal and external environment that completely cuts off bearing, for guaranteeing the rigidity of seal ring, the sealing lip thickness of existing bearing seal ring is bigger, the ability that causes sealing lip generation resiliently deformable a little less than, it is relatively more difficult when seal ring is embedded seal groove, also cause the damage of seal ring easily, and the sealability of this single sealing lip is relatively poor, tiny dust impurity can stick on the seal ring, infiltrates in the bearing with the prolongation of bearing service time, has reduced the working life of bearing.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of bearing sealed ring of easy for installation, good sealing effect is provided.
For achieving the above object, the technical solution of the utility model is: a kind of bearing sealed ring, comprise rubber elastomer and Steel Skeleton, there is a groove upper end portion of described rubber elastomer, the underpart of described rubber elastomer forms an arc lip and a straight lip, arc lip and straight lip surround and form a cavity, are filled with grease in the described cavity.
Described groove shapes is semicircle shape.
The beneficial effects of the utility model are: offer a semi-circular recesses by the upper end portion of rubber elastomer, easy for installation, fit closely, by in cavity, filling grease, stoped tiny dust impurity to infiltrate bearing inside, good seal performance has prolonged working life of bearing.
Description of drawings
Fig. 1 is installed in schematic representation on the bearing for the utility model;
Fig. 2 is schematic representation of the present utility model;
Fig. 3 is the bearing outer ring schematic representation.
Among the figure: rubber elastomer 1, upper end portion 11, groove 12, arc lip 13, straight lip 14, cavity 15, Steel Skeleton 2, bearing outer ring 3, draw-in groove 31, bearing inner race 4.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of bearing sealed ring, comprise rubber elastomer 1 and Steel Skeleton 2, there is a groove 12 upper end portion 11 of described rubber elastomer 1, the underpart of described rubber elastomer 1 forms an arc lip 13 and a straight lip 14, arc lip 13 and straight lip 14 surround and form a cavity 15, are filled with grease in the described cavity 15.
Described groove 12 is shaped as semicircle shape.
The upper end portion 11 of rubber elastomer 1 is fastened in the draw-in groove 31 of bearing outer ring 3 internal surfaces, and straight lip 14 is close on bearing inner race 4 outer surfaces, arc lip 13 and bearing inner race 4 outer surface interference fit.The utility model is offered a semi-circular recesses 12 by the upper end portion 11 of rubber elastomer 1, easy for installation, fit closely, by filling grease in the cavity 15 that is surrounded as at arc lip 13, straight lip 14 and bearing inner race 4, stoped tiny dust impurity to infiltrate bearing inside, good seal performance has prolonged working life of bearing.
Claims (2)
