Abstract
An oil reception seal strip belongs to the fittings for sealing rotating shaft technical field. The utility model is a flexible body formed by an embedded strip with the section showing a square or a big end down isosceles trapezoid and an oil reception belt which is integrally connected with the inner side of the embedded strip and warped to the inner upward side, wherein two strips of conical protuberance are alternately and parallel arranged on the lower end face of the protuberance; the oil reception belt shows an arc shape; the inner side of the bottom of the oil reception belt is a plane; the plane is slightly higher than the protuberance at the lower end of the embedded strip and separated from the protuberance on the inner side at the lower end of the embedded strip. The utility model can effectively prevent oil leaking from wheel axles.
Description
Technical field
The utility model belongs to the accessory technical field that is used for rotation axis seal, particularly a kind of Oil reception seal strip.
Background technique
Internal combustion, electric locomotive gear-box are up and down and welded-steel plate construction, and its static and dynamic sealing place adopts the sealing of malthoid bar, though make two seals into from the earliest sealing together, malthoid can only prevent dust and can not effectively prevent leakage of oil.Adopt rubber weather strip at present more existing gear-boxes, but because its structural design is unreasonable, sealing effect is still undesirable.
The model utility content
The utility model purpose is to provide a kind of Oil reception seal strip that is used in the good seal performance of gear-box upper plate inner seal groove.
For reaching above-mentioned purpose, the utility model by the following technical solutions: Oil reception seal strip, it for be square by the cross section or the setting-in bar of up-small and down-big isosceles trapezoid and the inside top perk that fuses with setting-in bar inboard connect the flexible body that the oil band constitutes.
Spaced and parallel is provided with two pyramidal projections on the setting-in bar lower end surface; Connect oil and be with curvedly, bottom inside is the plane, this plane a little higher than setting-in bar lower end projection and and setting-in bar lower end surface inside protrusions between have at interval.
The utility model adopts flexible elastic material to make, and structurally adopt the setting-in bar and connect the design that the oil band fuses, but embowment during use.The setting-in bar embeds in the gear-box upper plate inner seal groove, the oil from gear gets rid of under fall into the setting-in bar and connect oil between being with oil-containing groove and flow down along the groove two ends.Connect between the inboard pyramidal projections in oil band base plane and setting-in bar lower end surface and form isolation channel, two pyramidal projections on the setting-in bar lower end surface seal, and it is excessive to prevent that oil from dropping down onto running shaft upper edge axle, can effectively prevent leakage of oil, good seal performance.The utility model and outside dust-proofing seal coupling, can effectively prevent into dust and leakage of oil.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment embodiment, a kind of Oil reception seal strip, it is made by rubber material, be the setting-in bar 2 of up-small and down-big isosceles trapezoid and the arc of the inside top perk that fuses with setting-in bar inboard connects oil and is with 5 to constitute by the cross section, constitute oil-containing groove 4 between the two.Spaced and parallel is provided with two pyramidal projections 1 on the setting-in bar lower end surface, and connecing oil band bottom inside is the plane, this plane a little higher than setting-in bar lower end projection and and setting-in bar lower end surface inside protrusions between isolation channel 3 is arranged.
Claims (2)
1, Oil reception seal strip, the utility model be characterised in that, it for be square by the cross section or the setting-in bar of up-small and down-big isosceles trapezoid and the inside top perk that fuses with setting-in bar inboard connect the flexible body that the oil band constitutes.
2, Oil reception seal strip as claimed in claim 1 is characterized in that, spaced and parallel is provided with two pyramidal projections on the setting-in bar lower end surface; Connect oil and be with curvedly, bottom inside is the plane, this plane a little higher than setting-in bar lower end projection and and setting-in bar lower end surface inside protrusions between have at interval.
