Abstract
The invention discloses a seamless steel pipe for a bearing. The seamless steel pipe comprises a steel pipe body, wherein the steel pipe body comprises an outer pipe body and an inner pipe body; a plurality of bearing connecting grooves are formed in the inner pipe body; a plurality of annular convex rings are arranged at the upper end of the outer pipe body; a connecting flank is arranged at the bottom of the outer pipe body; the connecting flank and the outer pipe body are integrally molded. According to the seamless steel pipe for the bearing, the connecting stability of the steel pipe can be improved, and the seamless steel pipe is long in service life and simple in structure.
Description
Technical field
The present invention relates to seamless steel pipe field, particularly relate to a kind of bearing seamless steel pipe.
Background technique
Along with growth in the living standard, the machinery of processing and carrier mostly has high safety and reliability requirement for equipment and materials, original common stainless steel carft of construction, may not necessarily adapt to modern industry environment for the safety of the industries such as logistics and reliability requirement.Original steel pipe is easily corroded in use, and steel strength is more weak, shortens the working life of steel pipe, and the replacing of steel pipe, installation and maintenance are cumbersome, also also exists and is connected unstable defect with installation connecting element.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of bearing seamless steel pipe, and can improve the connective stability of steel pipe, long service life, structure is simple.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of bearing seamless steel pipe, comprise: steel pipe body, described steel pipe body comprises outer tube body and interior tube body, described interior tube body inside is provided with multiple bearing connecting groove, described outer tube body upper end is provided with multiple annular convex ring, and the bottom of described outer tube body is provided with connection flank, described connection flank and outer tube body one-body molded.
In a preferred embodiment of the present invention, described steel pipe body is integral type hollow tube, and described interior tube body and outer tube body are stainless steel body.
In a preferred embodiment of the present invention, described outer tube body is cylindrical, and the face, rank street of interior tube body is regular quadrilateral or triangle.
In a preferred embodiment of the present invention, the inside of described interior tube body is provided with anticorrosive coat, and the outer wall of described outer tube body is provided with pickling layer.
In a preferred embodiment of the present invention, the quantity of described bearing connecting groove is 4, and the quantity of described annular convex ring is 2.
The invention has the beneficial effects as follows: bearing seamless steel pipe of the present invention, can improve the connective stability of steel pipe, long service life, structure is simple.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of bearing seamless steel pipe one of the present invention preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, outer tube body, and 2, interior tube body, 3, bearing connecting groove, 4, annular convex ring, 5, connect flank.
Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, a kind of bearing seamless steel pipe, comprise: steel pipe body, described steel pipe body comprises outer tube body 1 and interior tube body 2, described interior tube body inside is provided with multiple bearing connecting groove 3, described outer tube body upper end is provided with multiple annular convex ring 4, and the bottom of described outer tube body is provided with and connects flank 5, described connection flank and outer tube body one-body molded.
In addition, described steel pipe body is integral type hollow tube, and described interior tube body 1 and outer tube body 2 are stainless steel body.
In addition, described outer tube body 1 is cylindrical, and the face, rank street of interior tube body 2 is regular quadrilateral or triangle.
In addition, the inside of described interior tube body 2 is provided with anticorrosive coat, and the outer wall of described outer tube body 1 is provided with pickling layer.
In addition, the quantity of described bearing connecting groove 3 is 4, and the quantity of described annular convex ring 4 is 2.
Be different from prior art, bearing seamless steel pipe of the present invention, can improve the connective stability of steel pipe, long service life, structure is simple.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
