Abstract

The utility model discloses a bearing sealing ring which comprises a sealing element and a steel framework, wherein the outer diameter end of the sealing element is arc-shaped; an upper lip, a middle lip and a lower lip are arranged at the inner diameter end of the sealing element; one edge of the sealing element is extended outside so as to form a protecting shoulder; the outer surface of the protecting shoulder is ripple-shaped. The bearing sealing ring is firmly mounted and good in sealing capability, and the service life of a bearing is prolonged.

Description

A kind of bearing sealed ring

Technical field

The utility model relates to a kind of seal ring, especially a kind of bearing sealed ring.

Background technique

Existing bearing sealed ring is easily loosening when being subject to high-torque, and by single lip seal poor effect.Be subjected to externally temperature influence; the varying aperture of bearing support is larger; existing bearing is firmly to contact cooperation with bearing support; often can be in the Spielpassung state; at this moment between bearing outer ring and bearing support, will produce relative movement; the wearing and tearing of aggravation bearing, cause bearing to lose efficacy in advance, reduced bearing working life.

The model utility content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and installs firmly, good seal performance, can extend the bearing bearing sealed ring in working life.

For achieving the above object, the technical solution of the utility model is: a kind of bearing sealed ring, comprise Sealing and Steel Skeleton, the external diameter termination of described Sealing is circular-arc, described inner seal diameter end is provided with upper lip, middle lip and lower lip, described Sealing one edge stretches out and forms a shoulder protector, and described shoulder protector outer surface is corrugated.

The beneficial effects of the utility model are: by the setting of circular-arc seal outer diameter termination, install firmly; By upper lip, middle lip, lower lip and bearing inner race, coordinate good seal performance; By outer surface, be the setting of undulatory shoulder protector, extended the working life of bearing.

The accompanying drawing explanation

Fig. 1 is that the utility model is arranged on the schematic diagram on bearing;

Fig. 2 is schematic diagram of the present utility model;

Fig. 3 is the enlarged view at A place in Fig. 1;

Fig. 4 is the bearing outer ring schematic diagram.

In figure: Sealing 1, external diameter termination 11, upper lip 12, middle lip 13, lower lip 14, shoulder protector 15, Steel Skeleton 2, bearing outer ring 3, sealed groove 31, bearing inner race 4, bearing support 5.

Embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of bearing sealed ring, comprise Sealing 1 and Steel Skeleton 2, the external diameter termination 11 of described Sealing 1 is circular-arc, described Sealing 1 inner-diameter end is provided with upper lip 12, middle lip 13 and lower lip 14, described Sealing 1 one edges stretch out and form a shoulder protector 15, and described shoulder protector 15 outer surfaces are corrugated.

The external diameter termination 11 of circular-arc Sealing 1 is fastened in the sealed groove 31 of bearing outer ring 3 internal surfaces, installs firmly; By upper lip 12, middle lip 13, lower lip 14 and bearing inner race 4 fitted seal, good seal performance; After bearing is pressed into to bearing support 5, one end face drive fit of shoulder protector 15 and bearing outer ring 3, utilize end face to compress bearing is fixed in bearing support 5, reach bearing outer ring 3 end face location, in the bearing operation process, seal ring and bearing support 5 produce friction, thereby stoped the rotation of bearing outer ring 3, shoulder protector 15 outer surfaces are arranged to corrugated, have increased frictional force, more effectively prevented the relative movement between bearing outer ring 3 and bearing support 5, prevent the wearing and tearing of bearing, extended the working life of bearing.

Claims

1. bearing sealed ring, comprise Sealing (1) and Steel Skeleton (2), it is characterized in that: the external diameter termination (11) of described Sealing (1) is for circular-arc, described Sealing (1) inner-diameter end is provided with upper lip (12), middle lip (13) and lower lip (14), described Sealing (1) one edge stretches out and forms a shoulder protector (15), and described shoulder protector (15) outer surface is corrugated.
