Abstract
The utility model relates to a gasket which comprises a ringlike constructional element. The ringlike constructional element is provided with an opening one, an opening two, a communicating opening one and a through hole of the opening two. The ringlike constructional element is arranged in a cone shape along the axial direction. The diameter of the opening one is larger than that of the opening two. A locating opening is arranged on the outer periphery surface of the ringlike constructional element along the axial direction. The locating opening penetrates one side of the ringlike constructional element along the axial direction or the radial direction. By adopting the technical scheme, the gasket has a locating function.
Description
Technical field
The utility model is specifically related to a kind of packing ring.
Background technique
Nowadays; packing ring has been applied to various fields as most basic connector element; the part of packing ring pad between connected piece and nut; be used for protecting the surface of connected piece not abraded by nut; disperse nut to the pressure of connected piece; present assembled shaft often needs the location when mounted, but traditional packing ring can't satisfy current needed function.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of packing ring with locating function.
For achieving the above object, the utility model provides following technological scheme: comprise annular construction member, described annular construction member is provided with the through hole of opening one, opening two and UNICOM's opening one and opening two, it is characterized in that: the diameter of the vertically tapered setting of described annular construction member and opening one is greater than the diameter of opening two, described annular construction member outer circumferential face is provided with locating aperture vertically, and described locating aperture axially reaches and radially runs through annular construction member one side.
By adopting technique scheme, the tapered setting of annular construction member, outer circumferential face can blocks dust enters and connects the slit that the place produces and reduce wear, and secondly, locating aperture can cooperate with the convex tendon on axle or the bar, reaches the effect of location.
The utility model further is set to: the inward flange of described opening one is provided with the installation chamfering.
By adopting technique scheme, chamfering is installed all axles or bar are sheathed in the annular construction member when mounted more easily.
The utility model further is set to: described annular construction member is made by the 40Cr steel.
By adopting technique scheme, the 40Cr steel is moderate, and easy processing can obtain certain toughness, plasticity and wear resistance after suitable heat treatment, is fit to very much produce in enormous quantities the required characteristic of packing ring.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the side view one of the utility model embodiment;
Fig. 2 is the side view two of the utility model embodiment.
Embodiment
Such as Fig. 1-shown in Figure 2, the utility model discloses a kind of packing ring, comprise annular construction member 1, annular construction member 1 is provided with opening 1, the through hole of opening 2 12 and UNICOM's opening 1 and opening 2 12, in the utility model embodiment, the diameter of vertically tapered setting of annular construction member 1 and opening 1 is greater than the diameter of opening 2 12, annular construction member 1 outer circumferential face is provided with locating aperture 13 vertically, locating aperture 13 axially reaches and radially runs through annular construction member 1 one sides, annular construction member 1 tapered setting, outer circumferential face can blocks dust enters and connects the slit that the place produces and reduce wear, secondly, locating aperture 13 can cooperate with the convex tendon on axle or the bar, reach the effect of location, the inward flange of opening 1 is provided with installs chamfering 111, chamfering 111 is installed makes all axles or bar be sheathed on more easily in the annular construction member when mounted, annular construction member 1 is made by the 40Cr steel, the 40Cr steel is moderate, easy processing, after suitable heat treatment, can obtain certain toughness, plasticity and wear resistance are fit to produce in enormous quantities the required characteristic of packing ring very much.
