Abstract
The utility model belongs to a sealing device, particularly an air valve guide rod oil seal especially used for motorcycle engines. The utility model comprises a framework and a sealed body adhering to the framework. One end of the sealed body is provided with a sealed lip, and the framework is positioned in the middle of the sealed body. The internal circumferential surface of the other end of the sealed body is provided with a shoulder matching with a groove of the external circumferential surface of an air valve guide pipe. The utility model provides the air valve guide rod oil seal used for motorcycles, so the problem that the prior motorcycle does not have an air valve guide rod is solved. Moreover, the utility model has long service life because of the advantages of strong deformation resistance, high temperature resistance, abrasion resistance, corrosion resistance, etc.
Description
Technical field
The utility model belongs to seal arrangement, especially belongs to the sealing between the surface of relative movement.
Background technique
Existing motorcycle, generally its valve guide rod does not all have oil sealing.A kind of vapour of prior art, diesel engine valve guide rod oil seal structure are as shown in Figure 1, it is by metal frame 1, form attached to the rubbery sealed body on the metal frame 12, rubbery sealed body 2 has sealing lip 3, in the groove of the position, back of sealing lip 3 spring 9 is set on seal 2.But, can't directly use this kind oil sealing because the valve guide rod of motorcycle is very tiny.
Summary of the invention
The purpose of this utility model is to provide a kind of motorcycle valve guide rod oil sealing.
For achieving the above object, the utility model comprises skeleton and attached to the seal on the skeleton, seal one end has sealing lip, and skeleton is positioned at the middle part of seal, and the other end inner peripheral surface of seal has the convex shoulder that is complementary with valve guide bushing outer circumferential face groove.
With the corresponding outer circumferential face in convex shoulder position groove is set on the seal, is provided with in the groove and steps up device.
Above-mentioned clamp device can be jump ring; The sectional shape of described skeleton is a rectangle.
The utility model is a kind of oil sealing that is specifically designed to the motorcycle valve guide rod, has adapted to the tiny characteristics of motorcycle valve guide rod; And owing to be provided with the former fluted convex shoulder that is complementary with valve guide rod on the oil sealing, making has increased stability by the oil sealing difficult drop-off.
Description of drawings
Fig. 1 is the structural representation of automobile valve guide rod oil sealing in the prior art.
Fig. 2 is the utility model example structure schematic representation.
Embodiment
The utility model embodiment's overall structure as shown in Figure 2, comprise the skeleton 1 that is positioned at seal 2 middle parts, seal 2 one ends have sealing lip 3, the inner peripheral surface of the other end of seal 2 has the convex shoulder 6 that is complementary with valve guide bushing 4 outer circumferential face grooves 5, with the corresponding outer circumferential face in convex shoulder 6 positions groove 7 is set on the seal 2, jump ring 8 is set in the groove 7; The sectional shape of described skeleton 1 is a rectangle.
During actual the use, the sealing lip 3 of oil sealing is compressed the generation resiliently deformable and closely is pressed on the guide rod, and an end that has jump ring 8 is enclosed within on the conduit, and the convex shoulder on the seal 6 is positioned at the groove 5 of catheter end head outer circumferential face just, valve guide rod is when work, and sealing lip 3 produces friction with it.Skeleton 1 is played a supporting role.
Owing to have the convex shoulder 6 that can embed in the catheter groove 7 on the seal 2, and in its back side groove 5 jump ring 8 is set, make oil sealing to be axially located well, cause to decrease and encircle, come off etc. and be unlikely to produce excessive deformation, and guaranteed the reliability and stability that seal with the guide rod axial float.
The utility model has provided a kind of oil sealing that can be used for the motorcycle valve guide rod, and it has solved the problem that existing motorcycle does not have valve guide rod.And the utlity model has stronger non-deformability, and have high temperature resistant, wear resistance, advantage such as resistance to abrasion is good, thereby have long working life.
Claims (4)
