Description
Technical field
The utility model relates to backbone sealing ring field, especially a kind of perfusion type lubrication backbone sealing ring.
Background technique
Backbone sealing ring and outside framework oil seal, the effect of oil sealing is exactly generally isolated with parts of exerting oneself by the parts needing in transmission part to lubricate, and is unlikely to allow oil seepage.Skeleton, just as the reinforcing bar inside concrete member, plays the effect of reinforcement, and makes oil sealing can keep shape and tension force.Single lip outside framework oil seal and Double-lip framework oil sealing can be divided by structural type.The secondary lip of Double-lip framework oil sealing plays dustproof effect, and prevent extraneous dust, impurity etc. enter machine intimate.But the sealing effect of existing Double-lip framework oil sealing is undesirable, and after sealing installation, can not to seal inside perfusion lubricating oil, operation inconvenience.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, and provide a kind of perfusion type lubrication backbone sealing ring, it is rational in infrastructure, good sealing effect, has high lubricating effect, conveniently injects lubricating oil.
The utility model solves the technological scheme that its technical problem adopts: a kind of perfusion type lubrication backbone sealing ring, comprises rubber layer, U-shaped skeleton and oiling passage, and described rubber layer is that to be coated on U-shaped skeleton outer; Described rubber layer inwall is provided with some sealing lips; " V " type lubrication groove is formed between described sealing lip;
Described oiling passage is the toroidal cavity structure be longitudinally arranged in the middle part of U-shaped skeleton; Some oiling through holes be interconnected with oiling passage are provided with in described " V " type lubrication groove; Described oiling channel roof is provided with fluid cavity volume; Described fluid cavity volume is provided with oiling uncovered; Annular sealing cover is provided with on described oiling is uncovered;
Described annular sealing cover and oiling uncovered between be provided with the seal trim strip of some mutual fastenings.
As preferred scheme, described sealing lip is four.
As preferred scheme, described U-shaped skeleton is that Elastic Steel is made.
The beneficial effects of the utility model are: a kind of perfusion type lubrication backbone sealing ring, the oiling passage adopting U-shaped skeleton and be arranged in the middle part of U-shaped skeleton, its oiling channel cavity does not affect sealing reliability, and the some oiling through holes be interconnected with oiling passage arranged in " V " type lubrication groove, lubricating oil is poured in " V " type lubrication groove, effectively lubricating seal, and it is uncovered that fluid cavity volume is provided with oiling, conveniently pours into lubricating oil.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of perfusion type lubrication backbone sealing ring overall structure schematic diagram described in the utility model.
Accompanying drawing acceptance of the bid note is described below: 1, rubber layer, and 11, sealing lip, 12, " V " type lubrication groove, 2, U-shaped skeleton, 3, oiling passage, 31, oiling through hole, 32, fluid cavity volume, 33, oiling is uncovered, 34, annular sealing cover, 35, seal trim strip.
