Abstract

The utility model relates to a sealing structure adopting a three-lip sealing piece with a framework and a dust preventing cover. The sealing structure adopts a three-lip sealing piece with a framework and a dust preventing cover, and comprises an outer circle, the framework, the dust preventing cover, the sealing piece and an inner circle. The sealing structure is characterized in that the outer diameter of the framework and the outer circle are in interference fit, the inner diameter of the dust preventing cover and the caliber of the inner circle are in the interference fit, the sealing piece is provided with three lips, two of the three lips and the framework are sealed in a matching way, and an outermost lip is contacted with the end surface of the dust preventing cover. The outer diameter of the framework and the caliber of the outer circle are in the interference fit, the inner diameter of the dust preventing cover and the caliber of the inner circle are in the interference fit, the rubber sealing piece is provided with the three inner lips, two of the three lips play a role of sealing grease, and the outmost lip is contacted with the end surface of the L-shaped dust preventing cover so as to play a role of preventing dust and block the invasion of outside dust, water and impurities.

Description

A kind of three lip seal with skeleton add the dust cover sealing configuration
Technical field
The utility model relates to a kind of three lip seal of the band skeleton of products such as double-row angular contact bal bearing, double-row conical bearing that are applicable to and adds the novel sealing structure of dust cover.
Background technique
The sealing configuration of products such as conventional double-row angular contact bal bearing or double-row conical bearing mostly adopts the two-lip seal of band skeleton; Product is owing to influenced by bad working environment such as high temperature, mud, water; The rubber epipharynx that seals is yielding, aging; Impurity such as dust, water is invaded from the outside easily, causes seal failure, influences product working life.
Summary of the invention
For overcoming the above problems, the utility model provides a kind of three lip seal with skeleton to add the dust cover sealing configuration.
The utility model solves the technological scheme that its technical problem adopted:
A kind of three lip seal with skeleton add the dust cover sealing configuration; Sealing configuration adds dust cover for three lip seal of band skeleton, and it comprises outer ring, skeleton, dust cover, Sealing, inner ring, it is characterized in that: skeleton external diameter and outer ring are interference fit; Dust cover internal diameter and inner ring bore are interference fit; Sealing band three lips, wherein two lips and skeleton fitted seal, outer lip contacts with the dust cover end face.
Skeleton external diameter of the utility model and outer ring bore are interference fit; Dust cover internal diameter and inner ring bore are interference fit; Three epipharynxs of rubber seal band, wherein inner two lips play seal grease, and outer lip contacts with L type dust cover end face; Play dustproof effect, stop the intrusion of external dust, water, impurity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure:
1-outer ring; 2-skeleton; 3-dust cover; 4-rubber seal; 5-inner ring.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
With reference to Fig. 1, skeleton 2 is a L type structure, and its external diameter and outer ring bore are interference fit, can prevent coming off of Sealing; Dust cover 3 is a L type structure, with the inner ring bore be interference fit, prevent that dust cover and inner ring from coming off; L type skeleton 2 has formed a square space with L type dust cover 3, and inside is provided with rubber seal 4.Because of rubber seal does not directly contact with the external world, defective such as that rubber can not produce is aging, distortion.Can improve sealability greatly.Three epipharynxs of rubber seal band, wherein inner two lips play seal grease, and outer lip contacts with L type dust cover end face, isolates fully with the external world product is inner, has stopped the intrusion of impurity such as external dust, water, has further improved the sealing of product.
