Abstract
The utility model relates to a shaft sleeve, comprising a first part and a second part which share the common circle center line, wherein the diameter of the first part is greater than the diameter of the second part, the center position of the first part is provided with a circular through hole, the circular through hole downwards runs through the second part, the second part is also provided with a groove which shares the same circle center with the circular through hole, the side face of the first part is provided with a plane, and a threaded hole is formed in the plane. The plane is arranged on the outer side face for forming the threaded hole, so that in the process of machining the threaded hole in the produced shaft sleeve, machining can be carried out on the plane, in such a way, the process requirement on forming the threaded hole in the side face of the shaft sleeve is greatly reduced, and further the production cost of the shaft sleeve is reduced.
Description
Technical field
The utility model relates to a kind of guard member, and 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 is now 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.
Model utility content
The utility model object is that a kind of axle sleeve is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of axle sleeve, comprises and have the First of concyclic heart line and second, the diameter that wherein diameter of First is greater than second; Described First is provided with manhole in heart position therein, and described manhole is downwards through second; On described second, be also provided with the groove with the concyclic heart of manhole; Described First is provided with a plane on its side, and offers in the plane tapped hole.
Further, described tapped hole is also 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 utility model compared with prior art has following advantages:
Axle sleeve described in the utility model is owing to for offering the outer side surface of tapped hole, plane being set, the axle sleeve of producing is being carried out in the course of working of tapped hole, can process 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation that accompanying drawing 1 is axle sleeve described in the utility model;
The sectional view that accompanying drawing 2 is axle sleeve described in the utility model;
Wherein: 1, First; 2, second; 3, manhole; 4, groove; 5, plane; 6, tapped hole; 7, rounding.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-2 is a kind of axle sleeve described in the utility model, comprises and has the First 1 of concyclic heart line and second 2, the diameter that wherein diameter of First 1 is greater than second 2; Described First 1 therein heart position is provided with manhole 3, and described manhole 3 is downwards through second 2; On described second 2, be also provided with the groove 4 with the manhole 3 concyclic hearts; Described First 1 is provided with a plane 5 on its side, and in plane 5, offers tapped hole 6.
Wherein said tapped hole 6 is also 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 described in the utility model is owing to for offering the outer side surface of tapped hole 6, plane 5 being set, the axle sleeve of producing is being carried out in the course of working of tapped hole 6, can in the plane 5 of axle sleeve, process, 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.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
