Background technique
Bearing is different according to practical operating mode, open type and enclosed two kinds can be selected, contact-type and contactless two kinds of seal form can be selected in closed bearing, for contact seal, we adopted the sectional shape of the seal ring of international most famous brand name KAYDON to be that the skeleton of " 7 " shape is gained in strength (as illustrated in figures ia and ib) in the past.Because uniform section ultra-thin-wall bearing structure is compact, the space of the cross section of limited space, skeleton shared by " 7 " shape is large, again because framework material is carbon steel, when manufacturing, carrying and load and unload seal ring, seal ring buckling deformation can be caused, even scrap, and need the seal ring that more renews.
As can be seen here, the seal ring skeletal structure of above-mentioned existing uniform section ultra-thin-wall bearing, structure with use obviously still has inconvenience and defect, and is urgently further improved.In order to solve above-mentioned Problems existing, relevant manufactures there's no one who doesn't or isn't seeks solution painstakingly, but has no applicable design for a long time always and completed by development, and this is obviously the anxious problem for solving of relevant dealer.
In view of the seal ring skeletal structure existing defects of above-mentioned existing uniform section ultra-thin-wall bearing, the present inventor is based on being engaged in the practical experience and professional knowledge that this type of product specification manufacture enriches for many years, and coordinate the utilization of scientific principle, actively in addition research and innovation, to founding a kind of seal ring skeletal structure of uniform section ultra-thin-wall bearing of new structure, the seal ring skeletal structure of general existing uniform section ultra-thin-wall bearing can be improved, make it have more practicability.Through constantly research, design, and through repeatedly studying sample and after improving, finally creating the present invention had practical value.
Summary of the invention
The object of the invention is to, the defect that the seal ring skeletal structure overcoming existing uniform section ultra-thin-wall bearing exists, and a kind of seal ring skeletal structure of uniform section ultra-thin-wall bearing of new structure is provided, technical problem to be solved makes its spatial volume little, good mechanical property, manufacture, carrying and handling seal ring time can not warpage, scrap, and starting friction moment is little when bearing uses, revolution flexibility is good, and good sealing effect, be very suitable for practicality.
The object of the invention to solve the technical problems realizes by the following technical solutions.The seal ring skeletal structure of a kind of uniform section ultra-thin-wall bearing proposed according to the present invention, it comprises: seal ring and skeleton; The sheet hollow cylinder spring steel structure of described skeleton to be sectional shape be rectangle, described seal ring is coated on the outside of described skeleton, and between the step that arranges of the age of a draught animal groove that arranges of the internal surface bilateral symmetry being installed on the outer ring of described uniform section ultra-thin-wall bearing and the outer surface bilateral symmetry of inner ring; Raceway groove is respectively equipped with in the centre of internal surface of outer ring of described uniform section ultra-thin-wall bearing and the centre of the outer surface of inner ring, rolling element is installed in the raceway groove of described uniform section ultra-thin-wall bearing outer ring and the raceway groove of inner ring, and is installed in the retainer between the outer ring and inner ring of described uniform section ultra-thin-wall bearing; Described seal ring and described skeleton are the both sides being installed on described rolling element and described retainer.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
The seal ring skeletal structure of aforesaid uniform section ultra-thin-wall bearing, wherein said seal ring is installed and is fixed in the age of a draught animal groove of the outer ring of described uniform section ultra-thin-wall bearing, and the bottom surface of the age of a draught animal groove of the outer surface of described seal ring and the outer ring of described uniform section ultra-thin-wall bearing is interference fit.
The seal ring skeletal structure of aforesaid uniform section ultra-thin-wall bearing, the surface of the step of the internal surface of wherein said seal ring and the inner ring of described uniform section ultra-thin-wall bearing is radial contact seal.
The present invention compared with prior art has obvious advantage and beneficial effect.By technique scheme, the seal ring skeletal structure of a kind of uniform section of the present invention ultra-thin-wall bearing at least has following advantages and beneficial effect: the seal ring skeletal structure of uniform section ultra-thin-wall bearing of the present invention adopts sectional shape to be that the sheet hollow cylinder spring steel of rectangle is as skeleton, its spatial volume is little, the good mechanical properties such as spring steel intensity, in manufacture, can not warpage when carrying and handling seal ring, scrap, and adopt radial contact seal, uniformity, when bearing uses, starting friction moment is little, revolution flexibility is good, manufacturing efficiency is high, good sealing effect.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
