Abstract
The utility model relates to a double-sealing bearing; the prior bearing has poor sealing effect; inner layered seal rings and outer layered seal rings are arranged between an inner ring and an outer ring on both sides of a steel ball at intervals, thereby the sealing effect is improved; the inner layered seal rings are designed in an F type, the outer layered seal rings are designed in an inverted F type, so that the two are complementary, so as to ensure the sealing effect; JDS glue is selected as the sealing material; 25 to 30 percent of oil is injected between the inner layered seal rings and the outer layered seal rings, to form a barrier, thereby effectively preventing outside dust from entering the bearing and preventing the bearing from failing; and the double-sealing bearing is applicable to adverse working environment, so that the service life is prolonged.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of bearing with double-layer sealing structure.
Background technique
Mostly existing bearing is the individual layer sealing configuration, and sealing effect is relatively poor, and when especially working in comparing bad working environment, the life-span shortens greatly.
The model utility content
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the relatively poor defective of sealing effect that prior art exists, and a kind of double sealed bearing is provided.For this reason, the utility model is by the following technical solutions:
Double sealed bearing comprises inner ring, outer ring, steel ball, retainer, it is characterized in that: each installs internal layer seal ring, outer seal ring at interval between the inner ring of described steel ball both sides and outer ring.
As preferably, annotate the grease of 25%-30% between described internal layer seal ring, the outer seal ring.
As preferably, have two outer shroud sealing notches on the described inner ring, the inward flange contact of described outer seal ring is in this outer shroud sealing notch, and the outward edge contact of described outer seal ring is on the outer ring; Have ring sealing notch in two on the described outer ring, in the ring sealing notch, the inward flange contact of described internal layer seal ring is on inner ring in this in the outward edge contact of described internal layer seal ring.
The beneficial effects of the utility model are:
1, each installs internal layer seal ring, outer seal ring at interval between the inner ring of steel ball both sides and outer ring, forms double-layer sealing structure, has strengthened sealing effect.
2, annotate the grease of 25%-30% between internal layer seal ring, outer seal ring, form barrier one, it is inner and cause bearing failure effectively to stop outside dust to enter bearing.
3, internal layer seal ring, outer seal ring adopt complementary mode to be assemblied on inner ring, the outer ring, thereby guarantee sealing effect.
4, be applicable to the comparison bad working environment, the life-span is prolonged.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Number in the figure explanation: 1-inner ring, 2-outer ring, 3-steel ball, 4-retainer, 5-internal layer seal ring, the outer seal ring of 6-, 7-outer shroud sealing notch, ring sealing notch in the 8-.
Embodiment
Below in conjunction with Figure of description the utility model is described further.
Double sealed bearing shown in Figure 1 comprises inner ring 1, outer ring 2, steel ball 3, retainer 4, and each installs internal layer seal ring 5, outer seal ring 6 at interval between both sides, inner ring 1 and the outer ring 2 of steel ball 3.
Further, have two outer shroud sealing notches 7 on the inner ring 1, the inward flange contact of outer seal ring 6 is in this outer shroud sealing notch 7, and the outward edge contact of outer seal ring 6 is on outer ring 2; Have ring sealing notch 8 in two on the outer ring 2, in the ring sealing notch 8, the inward flange contact of internal layer seal ring 5 is on inner ring 1 in this in the outward edge contact of internal layer seal ring 5; As the specific constructive form of seal ring, internal layer seal ring 5 adopts the design of F type, and outer seal ring 6 adopts reversed F-typed design, and for improving the wear resistance of seal ring, the sealing material of seal ring is selected JDS glue for use.For strengthening sealing effect, the interior ring sealing notch 8 on the outer ring 2 is carried out grinding.Annotate the grease of 25%-30% between internal layer seal ring 5, the outer seal ring 6.The material selection highi degree of accuracy SKF3 steel of inner ring 1, outer ring 2 is made, and makes the life-span of bearing reach more than 2 times of similar bearing.
