Abstract
The utility model discloses an oil seal structure with an independent framework plate. The oil seal structure with the independent framework plate comprises a vertical framework supporting ring and a horizontal framework supporting ring at intervals, and is characterized in that the vertical framework supporting ring is located outside the horizontal framework supporting ring and is integrated with the horizontal framework supporting ring through a rubber body in a vulcanization mode, a lip portion is arranged on the upper portion of the inner wall of the rubber body, a plurality of inverted thorn-shaped protrusion ribs are distributed on the upper end portion of the inner wall of the rubber body, a plurality of arc-shaped protrusions are distributed on the outer wall of the rubber body at intervals, and an outer flange is arranged on the upper end portion of the outer wall of the rubber body. The oil seal structure is reasonable in structural design, and can be elastically deform to a certain extent to meet using requirements of the situation that the oil seal structure is matched with a rotating shaft; because the inverted thorn-shaped protrusion ribs are matched with the lip portion, sealing area is increased, installation, sealing and matching are facilitated, and the overall stability and the sealing effect are good.
Description
Technical field
The utility model relates to a kind of oil seal structure, relates in particular to a kind of oil seal structure with the independent framework plate.
Background technique
Existing oil seal structure is simple, its inner metal framework structure is mostly whole structure, although it has very strong support force, but due to oil sealing in coordinating the rotating shaft using process, need to resiliently deformable to a certain degree be arranged with the rotation of rotating shaft, all-in-one-piece support frame resiliently deformable is limited, and existing oil sealing mostly adopts lip seal, its sealing area is little, affects sealing effect.
The model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of oil seal structure with the independent framework plate is provided.
The utility model is achieved through the following technical solutions:
A kind of oil seal structure with the independent framework plate, include the vertical skeleton support ring and the horizontal skeleton support ring that keep at a certain distance away, it is characterized in that: described vertical skeleton support ring is positioned at the outside of horizontal skeleton support ring, and between vulcanize and be integrated by rubber body, the upper end portion of described rubber body inwall is provided with lip, the upper end part of described rubber body inwall is furnished with several reversed acanthoid convex tendons, is intervally distributed with a plurality of arc convex on the outer wall of described rubber body, and the outer wall upper end portion is provided with flanging.
The lower end surface of described flanging is provided with the circular orientation projection.
Structural design by vertical skeleton support ring and horizontal skeleton support ring, it not only can be played a supporting role, but there is certain distance filled rubber body simultaneously, make it in use resiliently deformable to a certain degree can be arranged, meet the usage requirement while coordinating with rotating shaft, by several reversed acanthoid convex tendons of rubber body inwall, a plurality of arc convex of rubber body outer wall and the structural design that the outer wall upper end portion is provided with flanging, can increase sealing area, the convenient installation is sealed and matched, global stability is good, good sealing effect.
The utility model has the advantages that:
The utility model reasonable in design, make it in use resiliently deformable to a certain degree can be arranged, and meets the usage requirement while coordinating with rotating shaft, several reversed acanthoid convex tendons of while coordinate with lip, have increased sealing area, and convenient the installation is sealed and matched, global stability is good, good sealing effect.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of oil seal structure with the independent framework plate, include the vertical skeleton support ring 1 and the horizontal skeleton support ring 2 that keep at a certain distance away, vertical skeleton support ring 1 is positioned at the outside of horizontal skeleton support ring 2, and between by rubber body 3 sulfuration, be integrated, the upper end portion of rubber body 3 inwalls is provided with lip 4, the upper end part of rubber body 3 inwalls is furnished with several reversed acanthoid convex tendons 5, be intervally distributed with a plurality of arc convex 6 on the outer wall of rubber body 3, the outer wall upper end portion is provided with flanging 7.The lower end surface of described flanging 7 is provided with circular orientation projection 8.
