Abstract
The invention discloses a shaft sleeve. The shaft sleeve comprises a first part and a second part which have a common circle centre line, wherein the diameter of the first part is greater than the diameter of the second part, a circular through hole is formed in the central position of the first part, and the circular through hole downwards runs through the second part; a groove sharing the circle centre with the circular through hole is formed in the second part, a plane is arranged on the side face of the first part, and a threaded hole is formed in the plane. According to the invention, as the plane is arranged on the outer side face in which the threaded hole is formed, in the process of machining the threaded hole in a produced shaft sleeve, machining can be carried out on the plane, so that the technological requirements of the threaded hole formed in the side face of the shaft sleeve can be greatly reduced, and further, the production cost of the shaft sleeve is reduced.
Description
Technical field
The present invention relates to a kind of guard member, what be specifically related to is a kind of axle sleeve.
Background technique
Axle sleeve is a kind of common guard member, and it,, in the process of using, is fixed on axle, used axle has been played to the effect of protection.Wherein concerning that axle sleeve that tapped hole is set on the outer side surface of its axle sleeve, the method of offering tapped hole that technology is used now is directly to offer with milling machine, because its outer side surface of axle sleeve is circular, like this in offering the process of tapped hole, its technological requirement is higher, and then has improved the manufacture cost of axle sleeve.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of axle sleeve.
Technical solution of the present invention is achieved in that a kind of axle sleeve, comprises First with concyclic heart line and second one, the diameter that wherein diameter of First is greater than second one; Described First is provided with manhole in heart position therein, and described manhole is downwards through second one; Also be provided with the groove with the concyclic heart of manhole on described second one; Described First is provided with a plane on its side, and offers in the plane tapped hole.
Further, described tapped hole also is provided with rounding at the opening of adjacent plane position.
Further, the range difference between described groove and manhole is greater than the range difference between groove and second outer side surface.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described axle sleeve of the present invention program is because the outer side surface for offering tapped hole arranges plane, in the axle sleeve to producing carries out the course of working of tapped hole, can be processed in the plane, will greatly reduce the technological requirement that tapped hole is set on the side of axle sleeve like this, and then reduce the cost of production of axle sleeve.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation that accompanying drawing 1 is axle sleeve of the present invention;
The sectional view that accompanying drawing 2 is axle sleeve of the present invention;
Wherein: 1, First; 2, second one; 3, manhole; 4, groove; 5, plane; 6, tapped hole; 7, rounding.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1-2 is a kind of axle sleeve of the present invention, comprises First 1 with concyclic heart line and second one 2, the diameter that wherein diameter of First 1 is greater than second one 2; Described First 1 heart position therein is provided with manhole 3, and described manhole 3 is downwards through second one 2; Also be provided with the groove 4 with the manhole 3 concyclic hearts on described second one 2; Described First 1 is provided with a plane 5 on its side, and offers tapped hole 6 on plane 5.
Wherein said tapped hole 6 also is provided with rounding 7 at the opening of adjacent plane 5 positions; Range difference between described groove 4 and manhole 3 is greater than the range difference between groove 4 and second 2 outer side surface.
Axle sleeve of the present invention is because the outer side surface for offering tapped hole 6 arranges plane 5, in the axle sleeve to producing carries out the course of working of tapped hole 6, can on the plane 5 of axle sleeve, be processed, will greatly reduce the technological requirement that tapped hole 6 is set on the side of axle sleeve like this, and then reduce the cost of production of axle sleeve.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
