Abstract
The utility model discloses a shaft. The shaft comprises a shaft head, a shaft body, a shaft neck, a shaft tail and a regularly octagonal barrel body special-shaped sleeve which are molded in an integrated mode and all cylindrical, wherein the shaft head is provided with a key groove and a shaft central hole, two ends of the shaft tail are in a cylindrical structure with the lateral face provided with racks and the middle provided with an annular groove, one end of the shaft head is connected with one end of the shaft body in the axial direction, the other end of the shaft body is connected with the shaft neck in the axial direction, the other end of the shaft neck is connected with one end of the shaft tail in the axial direction, and the regularly octagonal barrel body special-shaped sleeve is sleeved outside the connection position between the shaft neck and the shaft tail. Due to the fact that the main body of the shaft and the special-shaped sleeve are machined separately and then assembled together, the machining accuracy is high, the production efficiency is high, the raw materials are saved, the cost is lowered at the same time, and the purposes of reasonable design, simple structure and convenient application are achieved.
Description
Technical field
The utility model relates to the mechanical parts field, is specifically related to a kind of axle.
Background technique
Axle is to be through in the middle of the bearing or the cylindrical object that wheel is middle or gear is middle, is square but small part is also arranged.Axle is supporting rotational parts and the mechanical parts that turn round therewith to transmit motion, moment of torsion or moment of flexure.It is shaft-like to be generally round metal, and each section can have different diameters.The part of doing rotation motion in the machine just is contained on the axle.
At present, the problem that the processing and fabricating industry of axle is often run into is: number axis all can be done location or limit structure mostly, and this moment need to be in the flat position of axis body processing, keyway or other structure; Because just material need to be excised in the part position, in the operating process, to locate or decide angle and can be restricted, difficulty of processing is large.
The model utility content
For solving the problems of the technologies described above, we have proposed a kind of axle, and by axle main body and abnormal shape cover are processed respectively rear assembled formation, not only machining accuracy height and efficient are high, and the while can save material and reduce cost.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of axle comprises the one-body molded special-shaped cover of spindle nose, axle body, axle journal, axle tail and an octagon cylindrical shell that all is cylindrical shape; Described spindle nose is provided with keyway and axle center hole, and described axle tail two ends are that the side is provided with the middle cylindrical structure that has circular groove of tooth bar; Described spindle nose one end axially is connected with described axle body one end; The described axle body the other end axially is connected with described axle journal one end; The described axle journal the other end axially is connected with described axle tail one end; Special-shaped axle journal and the described axle tail joint of being sheathed on of described octagon cylindrical shell.
Preferably, the described axle tail the other end is provided with center hole, and described center hole is cone structure.
Preferably, the joint of described axle body and described spindle nose has the shaft shoulder, and described shaft shoulder chamfering is processed.
Preferably, the special-shaped cover of described octagon cylindrical shell is provided with annular protrusion near described axle tail one end.
Pass through technique scheme, the utility model passes through axle main body and special-shaped cover are processed respectively rear assembled formation, and not only machining accuracy is high, and manufacturing efficiency is high, simultaneously can save material and reduce cost, thus reached design add up to, simple in structure and use easily purpose.

41. the special-shaped cover of tooth bar 42. circular grooves 43. center holes 5. octagon cylindrical shells
51. annular protrusion 6. shaft shoulders
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of axle, and its working principle is by with axle main body and special-shaped cover assembled formation after the processing respectively, and not only machining accuracy height and efficient are high, can save material simultaneously and reduces cost.
Below in conjunction with embodiment and embodiment the utility model is described in further detail.
Embodiment.
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of axle comprises the one-body molded special-shaped cover 5 of spindle nose 1, axle body 2, axle journal 3, axle tail 4 and an octagon cylindrical shell that all is cylindrical shape; Described spindle nose 1 is provided with keyway 11 and axle center hole 12, and described axle tail 4 two ends are that the side is provided with the tooth bar 41 middle cylindrical structures that have circular groove 42; Described spindle nose 1 one ends axially are connected with described axle body 2 one ends; Described axle body 2 the other ends axially are connected with described axle journal 3 one ends; Described axle journal 3 the other ends axially are connected with described axle tail 4 one ends; The special-shaped cover 5 of described octagon cylindrical shell is sheathed on axle journal 3 and described axle tail 4 joints.
Wherein, described axle tail 4 the other ends are provided with center hole 43, and described center hole 43 is cone structure; Firm with bearing fit herein in order to make, and easy for installation, described axle body 2 has the shaft shoulder 6 with the joint of described spindle nose 1, and the described shaft shoulder 6 chamferings are processed; The special-shaped cover 5 of described octagon cylindrical shell is provided with annular protrusion 51 near described axle tail 4 one ends.
In this example, can adopt spindle nose 1, axle body 2, axle journal 3 and the axle tail 4 of machining shaft main body on a machine tool, then at the special-shaped cover 5 of another lathe processing octagon cylindrical shell, at last the special-shaped cover 5 of the octagon cylindrical shell that processes closely is sheathed on axle journal 3 and gets final product with described axle tail 4 joints.Certainly, the special-shaped cover 5 of octagon cylindrical shell of the present utility model can not be confined to the abnormal shape cover of this kind shape, and the abnormal shape cover of other shape also can adopt the aforesaid way combination, and these equally all belong to protection domain of the present utility model.
Pass through technique scheme, the utility model passes through axle main body and special-shaped cover are processed respectively rear assembled formation, and not only machining accuracy is high, and manufacturing efficiency is high, simultaneously can save material and reduce cost, thus reached design add up to, simple in structure and use easily purpose.
Above-described only is the preferred implementation of a kind of axle of the utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
