Abstract
The utility model discloses a bearing provided with dustproof devices. The bearing comprises an outer ring, an inner ring, a plurality of steel balls and dustproof rings, wherein an annular step bulge is formed at the lateral side of the outer ring; the dustproof rings are arranged at the two lateral sides of the outer ring; one end of each dustproof ring is fixedly connected with the annular step bulge of the outer ring through screws; a ring of dustproof sponges is fixedly connected with the inner surface of the other end of each dustproof ring; an O-shaped sealing ring is arranged at the joint of each dustproof ring and the outer ring and the height of each dustproof sponge is greater than that of the step bulge. The bearing has the beneficial effects that the step bulge is formed on the outer ring, the dustproof rings are fixedly connected with the step bulge, an O-shaped sealing ring is arranged at the joint of each dustproof ring and the outer ring, the dustproof sponges are arranged between each dustproof ring and the inner ring, so that the steel balls are in a sealed space, external dust cannot enter into a space between the outer ring and the inner ring, the steel balls are not stuck and the bearing can operate normally.
Description
Technical field
The utility model belongs to field of bearings, relates in particular to a kind of bearing that is provided with dust guard.
Background technique
Existing bearing does not generally design dustproof device; make the bearing length time outside exposed, often there will be in bearing fouling phenomenon can occur, cause bearing to there will be stuck phenomenon when rotating; infringement to bearing is also larger, and shortened the working life of bearing.
The model utility content
The purpose of this utility model is the deficiency for above-mentioned technology, and a kind of bearing that is provided with dust guard is provided.
To achieve these goals, the utility model is that the technological scheme that its technical problem of solution is taked is:
A kind of bearing that is provided with dust guard, comprise outer shroud, interior ring and steel ball, described outer shroud side is provided with the step projection of an annular, also comprise dust ring, dust ring is located at the bi-side of outer shroud, and dust ring one end is fixed in by screw on the step projection of outer shroud, and the internal surface of the other end of dust ring is connected with a circle dustproof sponge.
Further, the joint of described dust ring and outer shroud is provided with O type seal ring.
Further, the height of described dustproof sponge is greater than the height of step projection.
The beneficial effects of the utility model: the outer step projection that is equipped with of the present utility model, dust ring is fixed on the step projection, and between dust ring and step projection, seal ring is set, be provided with dustproof sponge between dust ring and interior ring, make steel ball in seal space, extraneous dust can not enter between interior ring and outer shroud, can not cause the stuck of steel ball, guarantees that bearing can run well.
The accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
In order to make the utility model be convenient to understand, below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of bearing that is provided with dust guard as shown in Figure 1, comprise outer shroud 1, interior ring 2 and steel ball 3, it should be noted that, described outer shroud 1 side is provided with the step projection 4 of an annular, also comprise dust ring 5, dust ring 5 is located at the bi-side of outer shroud 1, and dust ring 5 one ends are fixed in by screw 6 on the step projection 4 of outer shroud 1, and the internal surface of the other end of dust ring 5 is connected with a circle dustproof sponge 7.
Further it should be noted that described dust ring 5 and the joint of outer shroud 1 are provided with O type seal ring 8.
Further it should be noted that the height of described dustproof sponge 7 is greater than the height of step projection 4.
The outer step projection that is equipped with of the present utility model, dust ring is fixed on the step projection, and between dust ring and step projection, seal ring is set, be provided with dustproof sponge between dust ring and interior ring, make steel ball in seal space, extraneous dust can not enter between interior ring and outer shroud, can not cause the stuck of steel ball, guarantees that bearing can run well.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
