Abstract
The utility model discloses a bearing sealing ring which comprises an inner steel frame, an outer steel frame and a slab rubber positioned between the inner steel frame and the outer steel frame, wherein the upper end part of the inner steel frame is bent into a circular arc, so as to wrap the upper end part of the outer steel frame; the lower end part of the outer steel frame is inclined outwards; three sealing lips are formed in the tail end of the slab rubber. According to the bearing sealing ring, the sealing effect is improved through arranging three sealing tips; because the inner steel frame and the outer steel frame are arranged on two sides of the sealing tips, and the lower end part of the outer steel frame is inclined outwards, the whole strength of the sealing ring is improved, the deformation of the sealing ring is prevented, the mechanical injury of the sealing tips is prevented effectively, and the service life of a 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 sealed ring is installed all on axle, to obtain effective sealing effect at present.This class seal ring is often only by single sealing lip and the sealing of single Steel Skeleton, and is relatively poor in the operating mode lower seal effect of heavily contaminated.Especially when being subject to larger moment, often cause sealed ring deformation owing to Steel Skeleton is loosening, the gap increases, and loses sealing effect, the spindle nose oil leakage phenomenon occurs.Simultaneously general bearing is invaded by external foreign material in operation process, can cause mechanical deterioration to sealing lip, 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 the bearing sealed ring of a kind of good sealing effect, long service life is provided.
For achieving the above object, the technical solution of the utility model is: a kind of bearing sealed ring, comprise the offset plate between interior Steel Skeleton, outer Steel Skeleton and Steel Skeleton and the outer Steel Skeleton, the upper end portion of described interior Steel Skeleton bends to circular arc and the upper end portion of outer Steel Skeleton is wrapped, the underpart of described outer Steel Skeleton is outward-dipping, and described offset plate end has three sealing lips.
The material of described offset plate is nitrile butadiene rubber.
The beneficial effects of the utility model are: improved sealing effect by establishing three sealing lips, by establish in the sealing lip both sides interior Steel Skeleton and outer Steel Skeleton and outside the underpart of Steel Skeleton outward-dipping, improved the bulk strength of seal ring, prevent sealed ring deformation, can effectively prevent again the mechanical deterioration of sealing lip, prolong the working life of bearing.
Description of drawings
Fig. 1 is that the utility model is installed in the schematic representation on the bearing;
Fig. 2 is schematic representation of the present utility model;
Fig. 3 is the schematic representation of bearing outer ring of the present utility model.
Among the figure: interior Steel Skeleton 1, outer Steel Skeleton 2, offset plate 3, sealing lip 31, bearing outer ring 4, draw-in groove 41, bearing inner race 5.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of bearing sealed ring, comprise the offset plate 3 between interior Steel Skeleton 1, outer Steel Skeleton 2 and Steel Skeleton 1 and the outer Steel Skeleton 2, the upper end portion of described interior Steel Skeleton 1 bends to circular arc and the upper end portion of outer Steel Skeleton 2 is wrapped, the underpart of described outer Steel Skeleton 2 is outward-dipping, and described offset plate 3 ends have three sealing lips 31.
The material of described offset plate 3 is nitrile butadiene rubber.
The upper end portion of interior Steel Skeleton 1 is fastened in the draw-in groove 41 of bearing outer ring 4 internal surfaces, three sealing lips 31 and bearing inner race 5 outer surface interference fit.The utility model has improved sealing effect by establishing three sealing lips 31, by establish in sealing lip 31 both sides interior Steel Skeleton 1 and outer Steel Skeleton 2 and outside the underpart of Steel Skeleton 2 outward-dipping, improved the bulk strength of seal ring, prevent sealed ring deformation, can effectively prevent again the mechanical deterioration of sealing lip 31, prolong the working life of bearing.
Claims (2)
1. bearing sealed ring, it is characterized in that: comprise interior Steel Skeleton (1), outer Steel Skeleton (2) and be positioned at Steel Skeleton (1) and outer Steel Skeleton (2) between offset plate (3), the upper end portion of described interior Steel Skeleton (1) bends to circular arc and the upper end portion of outer Steel Skeleton (2) is wrapped, the underpart of described outer Steel Skeleton (2) is outward-dipping, and described offset plate (3) end has three sealing lips (31).
