Technical field
The utility model relates to ball bearing technical field, relates in particular to a kind of high temperature resistant oil pressure double-layer rubber seal ball bearing.
Background technique
Ball bearing all has a wide range of applications in various mechanical devices, ball bearing must possess good sealing, therefore now with ball bearing, seal ring is installed mostly, wherein the effect of seal ring is mainly: prevent oiling agent from bearing to outward leakage and to prevent that outside dust, water and other pollutants from invading bearing inner.In prior art, ball bearing major part only comprises a seal ring.Sealing effect is bad, so also can cause ball bearing also can decrease working life.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of high temperature resistant oil pressure double-layer rubber seal ball bearing is provided, good sealing effect, can effectively prevent engine lubricating oil from ball bearing to external leakage, and there is high temperature resistant, withstand voltage characteristic.
The technical solution adopted in the utility model is as follows: a kind of high temperature resistant oil pressure double-layer rubber seal ball bearing, comprise inner ring, outer ring, retainer, steel ball and be arranged at the double-layer seal rings between described inner ring, outer ring, described double-layer seal rings comprises left rubber seal, right rubber seal, at the section middle part of right rubber seal, the right seal groove of depression is to the right set.
Further, in described left rubber seal, sulfuration is provided with L shaped skeleton, the section inner edge of described left rubber seal arranges Y-shaped left seal epipharynx limit, outer rim arranges left seal outer lip limit, middle part arranges left seal contact lip limit, the right-hand member on described left seal contact lip limit slopes inwardly to the right, and is resisted against on the bottom land of right seal groove.
Further, in described right rubber seal, sulfuration arranges groove shape skeleton, the section inner edge of described right rubber seal arranges right seal epipharynx limit, outer rim arranges right seal outer lip limit, and described right seal groove is between right seal epipharynx limit and right seal outer lip limit.
Further, the inwall in outer ring arranges the first seal groove, deducts in the first seal groove in described left seal outer lip limit.
Further, at the outer wall of inner ring, the second seal groove being set, deducts in the second seal groove in described right seal epipharynx limit.
The beneficial effects of the utility model are, ball bearing structure of the present utility model is reasonable, there is double-layer rubber seal ring, good sealing effect, long service life, the left seal contact lip limit that the sloping inwardly to the right of left rubber seal uniqueness arranges makes the lubricant oil can be by ball bearing to external leakage, the premium properties that double-layer rubber seal ball bearing has is high temperature resistant, oil resistant is pressed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference character: 1-inner ring, 2-outer ring, 3-retainer, 4-steel ball, the left rubber seal of 5-, the right rubber seal of 6-, 7-the first seal groove, 8-the second seal groove, the right seal groove of 9-, 5-1-L shape skeleton, the left seal epipharynx of 5-2-limit, the left seal outer lip of 5-3-limit, the left seal contact of 5-4-lip limit, 6-1-groove shape skeleton, the right seal epipharynx of 6-2-limit.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
A high temperature resistant oil pressure double-layer rubber seal ball bearing as shown in Figure 1, comprise inner ring 1, outer ring 2, retainer 3, steel ball 4 and be arranged at inner ring 1 and inner ring 2 between double-layer seal rings.Double-layer seal rings comprises left rubber seal 5 and right rubber seal 6.On the madial wall of on the outer side wall of inner ring 1 and outer ring 2, be respectively arranged with groove, steel ball 4 is stuck in the groove of inner ring and outer ring, steel ball 4 both sides are respectively arranged with two retainers 3, on the madial wall of outer ring and on the outer side wall of inner ring, are respectively arranged with the first seal groove, the second seal groove.The interior sulfuration of left rubber seal 5 is provided with L shaped skeleton 5-1; The section inner edge of left rubber seal 5 arranges Y-shaped left seal epipharynx limit 5-2, outer rim arranges left seal outer lip limit 5-3, middle part arranges left seal contact lip limit 5-4, the right-hand member of left seal contact lip limit 5-4 slopes inwardly to the right, and be resisted against on the bottom land of right seal groove 9, left seal outer lip limit 5-3 deduction is in the first seal groove 7.The interior sulfuration of right rubber seal 6 arranges groove shape skeleton 6-1; The section inner edge of right rubber seal 6 arranges right seal epipharynx limit 6-2, outer rim arranges right seal outer lip limit 6-3, and right seal groove 9 is between right seal epipharynx limit 6-2 and right seal outer lip limit 6-3.Right seal epipharynx limit 6-2 deduction is in the second seal groove 8.The unique design of left seal contact lip limit 5-4 makes right seal groove 9 form a closed-loop path, even if accidentally there is lubricant oil to enter right seal groove by left seal epipharynx limit, also can not make oil leak go out.
