Abstract
The utility model relates to an axial oil seal, which comprises an oil seal body (1). The oil seal body (1) comprises a bending portion (1.1), and a dustproof lip (1.2) is arranged on the lower portion of the outside of the bending portion (1.1). The axial oil seal is characterized in that backward prick-shaped protruding ribs (2) are arranged on the contact portion of the bending portion (1.1) and a force exertion portion. A plurality of backward prick-shaped protruding ribs are contacted with the force exertion portion, a plurality of stopping dams are formed, thereby effectively stopping oil or oil liquid from leaking outwards, and then improving sealing property.
Description
Technical field
The utility model relates to a kind of axial seal.
Background technique
Oil sealing is to be used for the mechanical component of oil sealing, and its is needing the lubricated parts and the parts of exerting oneself to isolate in the transmission part, is unlikely to let oil seepage.The representative form of oil sealing is the TC oil sealing, and this is the two-lip seal of the band self-tightening spring that coats fully of a kind of rubber, and the oil sealing of generally saying often refers to this TC outside framework oil seal.Conventional outside framework oil seal is in the oil sealing body, to set L font skeleton, makes the one of which side form deflection division, forms to cut at the deflection division top and has a shave, and the outer side-lower of deflection division is provided with dust excluder lips.This kind oil sealing is smooth plane with the parts contact position of exerting oneself, and during work, oil sealing is prone to the generation gap with exerting oneself between the parts contact position, grease or fluid easily along this gap to external leakage, thereby influence sealing effect.
Summary of the invention
The utility model is to overcome above-mentioned deficiency, and a kind of good airproof performance, antileakaging axial seal are provided.
The purpose of the utility model is achieved in that a kind of axial seal, and it comprises the oil sealing body, comprises deflection division on the said oil sealing body, and the outer side-lower of said deflection division is provided with dust excluder lips, and said deflection division is provided with the reversed acanthoid convex tendon with the parts contacting point of exerting oneself.
Said reversed acanthoid convex tendon has multiple tracks.Be preferably the 3-5 road.
Compared with prior art, the beneficial effect of the utility model axial seal is:
The utility model axial seal, multiple tracks reversed acanthoid convex tendon contacts with the parts of exerting oneself, and forms multiple tracks interception dam, effectively stops grease or fluid to external leakage, thereby improves sealability.
Description of drawings
Fig. 1 is the structural representation of the utility model axial seal.
Among the figure:
Deflection division 1.1;
Dust excluder lips 1.2;
Cut and have a shave 1.3;
Convex tendon 1.4.
Embodiment
Referring to Fig. 1; The utility model axial seal, it comprises oil sealing body 1, sets L font skeleton 2 in the said oil sealing body 1; Make the one of which side form deflection division 1.1; Said deflection division 1.1 tops form to cut has a shave 1.3, and deflection division 1.1 outer side-lowers are provided with dust excluder lips 1.2, and said deflection division 1.1 is provided with reversed acanthoid convex tendon 2 with the parts contacting point of exerting oneself.
Said reversed acanthoid convex tendon 2 has multiple tracks, is preferably the 3-5 road.
During use, multiple tracks reversed acanthoid convex tendon 2 contacts with the parts of exerting oneself, and forms multiple tracks interception dam, effectively stops grease or fluid to external leakage, thereby improves sealability.
Claims (3)
1. axial seal; It comprises said oil sealing body (1); Comprise deflection division (1.1) on the said oil sealing body (1); The outer side-lower of said deflection division (1.1) is provided with dust excluder lips (1.2), it is characterized in that: said deflection division (1.1) is provided with reversed acanthoid convex tendon (2) with the parts contacting point of exerting oneself.
2. a kind of axial seal according to claim 1 is characterized in that: said reversed acanthoid convex tendon (2) has multiple tracks.
