Abstract
The invention discloses a large composite-structure sealing element for a rotating shaft. The large composite-structure sealing element is formed by integrally combining a framework (1), a rubber sealing lip (2) and a leaf spring (3) and is mainly characterized in that the leaf spring (3) is arranged behind the rubber sealing lip (2) and inlaid in the rubber sealing lip (2), and ribs are arranged on the framework (1). The working conditions are stable, the sealing performance is reliable, the following performance of the lip is good, the leaf spring (3) doesn't easily fall off, the service life is long, the mounting is convenient, the universality and the interchangeability are good, the large composite-structure sealing element can better adapt to the sealing working condition of a large-specification rotating shaft, and the problem that conventional oil-seal springs easily fall off is solved.
Description
The present invention relates to a kind of large complex structure sealing member for rotating shaft (rotation shaft seal be otherwise known as oil sealing), it is adapted to the operating mode of big specification rotation axis seal, solve the tradition caducous problem of oil seal spring, and the concordance of product can be improved.The invention belongs to industrial machinery sealing member manufacturing technology field.
Background technology
The structural behaviour of tradition oil sealing is to be provided with spring groove on rubber seal lip, and spring is arranged in spring groove.When traditional oils seal structure is applied to the sealing of big specification rotating shaft, sealing required enough radial forces to provide, it is comparatively short that spring is produced, in order to allows spring with bigger power banding lip.So, traditional oils is enclosed in transport and installation process and easily comes off；The more important thing is that spring also easily comes off in oil sealing use procedure, causes the accident that seal failure is revealed.
Summary of the invention
In order to solve the problems referred to above, the present invention takes a kind of new design.Having the present invention relates to a kind of large complex structure sealing member for rotating shaft, rubber seal lip (2) has zigzag spring leaf (3), spring leaf (3) to be embedded in rubber seal lip (2) behind, and skeleton has fin on (1).
It is an object of the invention to the deficiency existed for prior art, provide the large complex structure sealing member of a kind of rotating shaft, it is not good that this seal configuration can be used to solve tradition lip-type packing sealing property, and spring holds caducous problem, and can improve the concordance of product.
The composite construction sealing member of a kind of large-scale rotating shaft for rotating shaft, is composited an entirety by skeleton (1), rubber seal lip (2), spring leaf (3) entirety.Skeleton (1), rubber seal lip (2), spring leaf (3) are combined into an entirety by the mode of overall sulfidization molding.
Rubber seal lip (2) has zigzag spring leaf (3) behind.Spring leaf (3) indentation can make it better be embedded in rubber seal lip (2), difficult drop-off.Spring leaf (3) and rubber seal lip (2) combine also by the mode of bonding except tessellation.
Skeleton (1) is provided with fin, for the size of stabilized seal part.
The present invention improves the sealing property of rotation shaft seal, extends the service life of rotation shaft seal, reduces the frequency changing rotation shaft seal, improves equipment service efficiency, reduce the maintenance cost of equipment, reduce production cost.
Below in conjunction with accompanying drawing, the present invention is described further.
Accompanying drawing explanation

Fig. 2: skeleton structure diagram
Fig. 3: chip architecture of the spring figure
Wherein:
In Fig. 1: 1. skeleton, 2. rubber seal lip, 3. spring leaf.
In Fig. 2: for the structure chart of skeleton (1).
In Fig. 3: for the structure chart after spring leaf (3) line excision forming.
Detailed description of the invention
Embodiment:
The processing technique of skeleton (1) is as follows:
Skeleton (1): the first step, to cord kiss-coating；Second step, is overlapped to form cylindrical shape by cloth, and joining seam binding agent bonds and dries；Cloth cylinder is twisted into volume by the 3rd step；4th step, rolls into cloth and uses vulcanizing press sizing in molding fetal.
The processing technique of spring leaf (3) is as follows:
Spring leaf (3): the first step, line cuts into regulation shape；Second step, punch forming established practice shaped；3rd step, surface treatment；4th step, coating adhesive also dries.
Processing technique for the large complex structure sealing member (Fig. 1) of rotating shaft is as follows:
The first step: put into skeleton and appropriate rubber in a mold, carry out pre-setting；Second step, puts into spring leaf；3rd step, uses vulcanizing press to vulcanize.4th step, repaiies overlap.So far completion of processing.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, those skilled in the art, in the essential scope of the present invention, and change, remodeling, interpolation or the replacement made, all should belong to protection scope of the present invention.
Claims (5)
