Abstract

The utility model provides a sealing washer is provided with a plurality of thorn that exceed the terminal surface height on the terminal surface of sealing washer, sets up the thorn on the sealing washer terminal surface, and axial interference fit between the bearing, not only can ignore the influence that thermal treatment warp and cause, simple to operate moreover, firm, stable in quality.

Description

Sealing ring

Technical Field

The utility model belongs to the sealing washer field especially relates to a sealing washer.

Background

The bearing sealing element is a ball bearing sealing ring, is matched with an inner ring and an inner diameter in a groove, is a resistance factor of vehicle power rolling, is a sealing element which must be used under the generated friction and dust-proof effects, and is generally used in the fields of automobile water pumps, industrial water pumps, agricultural machinery and the like.

The bearing sealing element is arranged in a dust-proof groove of the outer ring of the bearing of the mechanical equipment, the dust-proof groove is prevented from loosening at a fixed position, and after the bearing is pushed into the seat hole by pressure, the bearing is pressed in the seat hole by utilizing the lip surface of the sealing element to be positioned by the end face of the outer ring of the bearing.

The conventional sealing adopts a radial interference mode, is influenced by the heat treatment deformation of the ferrule, and has large and small interference magnitude and unstable quality between the sealing ring and the dustproof groove.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a sealing washer, the influence that thermal treatment warp and cause, simple to operate moreover, firm, the steady quality, the utility model discloses a following technical scheme realizes: the end face of the sealing ring is provided with a plurality of thorns higher than the end face.

Preferably, a plurality of thorns are arranged on the inner end surface of the sealing ring.

Preferably, the plurality of barbed annular arrays are distributed on the inner end face of the outer ring of the sealing ring.

Preferably, the barbs are of a quadrangular pyramid or cone configuration.

Preferably, the inner end face of the outer ring of the sealing ring is a plane, the thorns are vertically arranged on the plane, and the tips of the thorns are far away from the inner end face of the outer ring.

Preferably, a plurality of pattern grooves or reticulate pattern grooves can be distributed on the inner end face of the outer ring of the sealing ring.

Preferably, an inclined circular soft structure is further arranged inside the inner ring of the sealing ring.

The utility model has the advantages that: the inner end face of the outer ring of the sealing ring is provided with the spines which are in axial interference fit with the bearing, so that the influence caused by heat treatment deformation can be ignored, and the sealing ring is convenient and firm to install and stable in quality.

FIG. 2 is an enlarged view of a portion of any one of the arc segments of FIG. 1;

FIG. 3 is a schematic view of a structure cooperating with a bearing;

1. a sealing ring 101, an outer ring 102, an inner ring 103 and a soft structure; 2. a dust-proof groove; 3. there are thorns.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A plurality of thorns higher than the end face are arranged on the inner end face of an outer ring of a sealing ring, and the thorns are arranged on the end face contacting with a dustproof groove to realize axial interference fit with the dustproof groove of a bearing, as shown in figures 1 and 2.

Preferably, the inner end face of the outer ring of the sealing ring is a plane, and the plurality of thorn annular arrays are distributed on the inner end face of the outer ring of the sealing ring.

Preferably, the spine is in a quadrangular pyramid or cone structure, the spine is perpendicular to the plane of the end face of the outer ring, and the tip of the spine is far away from the inner end face of the outer ring, and when sealing, the tip is placed in the dust-proof groove of the bearing to realize axial matching, as shown in fig. 3.

Preferably, the inner end surface of the outer ring of the sealing ring can be a plane, and a plurality of pattern grooves or reticulate pattern grooves can be distributed on the inner end surface of the outer ring of the sealing ring.

Preferably, the inner ring of the sealing ring is also internally provided with an inclined circular soft structure, so that the dustproof and oil-leakage-proof effects are realized.

It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
