Description
Technical field
The utility model relates to a kind of Sealing, and more particularly, it relates to a kind of oil sealing.
Background technique
Outside framework oil seal is the Typical Representative of oil sealing, and namely oil sealing in general refers to 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.Interior bag outside framework oil seal can be divided into, exposed framework oil seal and assembling type oil sealing by skeleton pattern.Can be divided into by operating conditions and rotate outside framework oil seal and reciprocating type outside framework oil seal.For crankshaft for gasoline engine, diesel engine machine crankshaft, gearbox, differential mechanism, vibration damper, motor, the positions such as vehicle bridge.
But in order to outside framework oil seal can be made, there is more outstanding sealing effect, just there is the multiple lip seal of more than three lips or even three lips, it is in multiple lip seal, under identical material, the sealing effect of three lip oil sealings there is no outstanding feature compared with Double-lip framework oil sealing, little on sealing effect impact; And multiple lip seals more than three lips, although sealing effect is more outstanding, structure is more complicated compared with above-mentioned oil sealing, not easily processing, low in economic efficiency, does not meet reality.
So just need the superior and oil sealing of the simple and convenient processing of structure of its sealability a kind of.

Embodiment
Referring to figs. 1 through Fig. 5, the utility model oil sealing embodiment is described further.
A kind of oil sealing, comprise the skeleton 1 that centre is provided with through hole 2, described skeleton 1 wraps up and is coated with rubber layer 3 on the sidewall of through hole 2, described rubber layer 3 is convexly equipped with some annular seal lips 4, described annular seal lip 4 is inclined on rubber layer 3, end face away from rubber layer 3 on described annular seal lip 4 there is the first seamed edge 41 and the second seamed edge 42, the annulus that described first seamed edge 41 surrounds directly is greater than the circle diameter that the second seamed edge 42 surrounds, and the end face away from rubber layer 3 on described annular seal lip 4 is fixed with conflict ring 5.Its rubber layer 3 mainly playing sealing effect is only arranged on skeleton 1 sidewall, completely skeleton 1 is not wrapped up, can save production raw material of the present utility model greatly like this, the structure of its rubber layer 3 is more simple, greatly facilitates production of the present utility model.
And the annular seal lip 4 be provided with on rubber layer 3 is provided with conflict ring 5, and the quantity of conflict ring 5 is 3, and the annular seal lip 4 of such quantity can increase sealability of the present utility model, can not make again the complexity that structure of the present utility model becomes.And tilting upward of conflict ring 5 is arranged on rubber layer 3, its tilt angle is 40 ° to 50 °, and it is best with the sealing effect of the annular seal lip 4 that the inclination angle of 45 ° is arranged.
The axis cross section of described conflict ring 5 is equilateral triangle, the sidewall of conflict ring 5 comprises the first side wall 51, second sidewall 52 and the 3rd sidewall 53, described the first side wall 51 and O-ring seal coincide, and the vertical projection that described conflict ring 5 intersects by the second sidewall 52 and the 3rd sidewall 53 seamed edge vertical projection and the second seamed edge 42 formed coincides.
On described conflict ring 5, the first side wall 51 seamed edge that formed crossing with the second sidewall 52 and the first seamed edge 41 coincide.
Second sidewall 52 of described conflict ring 5 parallels with horizontal plane.
When the utility model uses, its annular seal lip 4 all can be inconsistent with axle rotary member with conflict ring 5, and be all intersect the seamed edge that formed and inconsistent with axle rotary member by the second sidewall 52 on the second seamed edge 42 of annular seal lip 4 and conflict ring 5 and the 3rd sidewall 53, sealability of the present utility model can be made like this to obtain double reinforcement, and because the area of contact of seamed edge is less, the so just frictional force of the good control the utility model of energy and axle rotary member, thus facilitate the rotation of axle rotary member.
At these seamed edges after these wearing and tearing, new resistance surface will be produced, be fitted on axle rotary member by the elastic tight of annular seal lip 4, substantially increase sealing effect of the present utility model.
And the first side wall 51 seamed edge that formed crossing with the second sidewall 52 and the first seamed edge 41 coincide on conflict ring 5.Second sidewall 52 of conflict ring 5 parallels with horizontal plane.Such dust just can effectively fall in angle that annular seal lip 4 and rubber layer 3 formed and on the second sidewall 52 of conflict ring 5, and facilitates the utility model in the process used because the discharge of rubber scraps that produces of wearing and tearing.
Described annular seal lip 4 is provided with rounding 6 with the joint of rubber layer 3.The setting of rounding 6 both can not make the utility model produce dead angle, cleaning-nursing work is carried out to the utility model, but also greatly strengthen annular seal lip 4 and rubber layer 3 join strength, make annular seal lip 4 and rubber layer 3 joint can have better wilfulness, greatly increase working life of the present utility model.
Lateral loops 11, lower lateral loops 12 and longitudinal connecting ring 13 on described skeleton 1, the annular diameters of described upper lateral loops 11 is a, and the outer annular diameter of described lower lateral loops 12 is b, a=b; Described upper lateral loops 11 is fixedly installed on longitudinal connecting ring 13 two ends respectively with lower lateral loops 12 is perpendicular, and described rubber layer 3 covers and is arranged on longitudinal connecting ring 13 inwall, the inwall of lower lateral loops 12 and the upper-end surface of lower lateral loops 12.
Rubber layer 3 covers and is arranged on longitudinal connecting ring 13 inwall, the inwall of lower lateral loops 12 and the upper-end surface of lower lateral loops 12, and rubber layer 3, annular seal lip 4 and conflict ring 5 are all formed by butyronitrile rubber integrated injection molding, and its annular seal lip 4 is inclined at demoulding rubber layer 3 greatly facilitating product.Improve manufacturing efficiency of the present utility model.
And skeleton 1 is made up of alloyed steel, and can ensure that skeleton 1 has enough intensity by the effect of upper lateral loops 11, lower lateral loops 12 and longitudinal connecting ring 13, thus facilitate installation of the present utility model to fix.
On it, lateral loops 11 is fixedly connected with longitudinal connecting ring 13, and be all light face on longitudinal connecting ring 13 with the sidewall of upper lateral loops 11 homonymy, so both saved raw materials of the present utility model, and be conveniently fixed on other workpiece with the fixing angle formed of longitudinal connecting ring 13 by upper lateral loops 11.
Lower lateral loops 12 is fixedly connected with longitudinal connecting ring 13, can play and support fixing function, facilitate the installation of rubber layer 3 and fix rubber layer 3.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
