Below with reference to Fig. 1-Fig. 6, describe according to the axis hole mounting structure 100 of the utility model first aspect embodiment's electric component.The axis hole mounting structure 100 of electric component is applicable in any machinery that needs axis hole connection, coordinates.
As shown in Fig. 1-Fig. 6, according to the axis hole mounting structure 100 of the utility model embodiment's electric component, comprise axle 1 and the axis hole 2 coordinating with axle 1.Especially, according in the axis hole mounting structure 100 of electric component of the present utility model, axle 1 can rotate in axis hole 2.
Wherein, axle 1 comprises axle main body 11, and in embodiments more of the present utility model, axle main body 11 is directed along the vertical direction, and axle main body 11 is roughly cylindrical.In axle main body 11, have axle 1 to axle mold joint 14, axle 1 line of axle main body 11 is positioned on axle mold joint 14, is formed with mold joint intersects and dodges plane 15, in axle main body 11 on the cross section of axle main body 11, as shown in Figure 4, dodge the inner side that plane 15 is positioned at the cross section of axle main body 11.Axle main body 11 is provided with at least two along axle 1 to the isolated circular groove of direction, and hole mold joint 21 is relative with any one at least two grooves.
Owing to arranging and dodging plane 15 in axle main body 11, it is crossing with axle mold joint 14 that this dodges plane 15, can avoid like this mold joint to criticize cutting edge of a knife or a sword contacts with the inwall of axis hole 2, affect the assembling of axle 1 and axis hole 2, can effectively improve the quality of fit of axle 1 and axis hole 2, reduce the noise that axle 1 rotates in axis hole 2, make coordinating of axle 1 and axis hole 2 stable, extend life of product, improve the quality of products.
Wherein, at least two circular grooves remaining circular groove and the inwall of axis hole 2 between form holding space, can be for storing lubricant oil.In coordinating in rotation process of axle 1 and axis hole 2, no matter quality of fit is high again, all can produce friction, can cause for a long time the wearing and tearing of material itself.Thus, in axle main body 11, be provided for storing the second circular groove 162 of lubricant oil, friction in the time of can reducing axle 1 and relatively rotate with respect to axis hole 2, greasy property when raising axle 1 rotates in axis hole 2, further reduce the noise of the rotation of axle 1 in axis hole 2, greatly strengthen product working life.
To sum up, according to the axis hole mounting structure 100 of the utility model embodiment's electric component, by arranging and dodge plane 15 and circular groove on axle 1, from above, can effectively improve the quality of fit of axle 1 and axis hole 2, reduce the noise that axle 1 rotates in axis hole 2, make axle 1 stable with coordinating of axis hole 2, extend life of product, improve the quality of products.
Particularly, in example as shown in Figure 1, axle main body 11 be provided with two along axle 1 to direction (being above-below direction) isolated circular groove, two circular grooves comprise the first circular groove 161 and the second circular groove 162, the first circular groove 161 is relative with hole mold joint 21, wherein, the first circular groove 161 can be positioned at the lower end of axle main body 11, and the second circular groove 162 is for storing lubricant oil.
As shown in Fig. 1 and Fig. 6, the second circular groove 162 edges are circumferentially run through and are dodged plane 15, that is to say, the second circular groove 162 will be dodged plane 15 and is separated into upper and lower two parts.Because the spacing of dodging between plane 15 and the inwall of axis hole 2 is large, can store more lubricant oil like this.
Advantageously, the axle 1 of dodging plane 15 is positioned on axle mold joint 14 to center line (dodging the center line along the vertical direction of plane 15), and in other words, the axle 1 of dodging plane 15 overlaps with axle mold joint 14 to center line.Owing to dodging the spacing maximum of the axle 1 line center of plane 15 from the inwall of axis hole 2, by the axle 1 of dodging plane 15 is overlapped with axle mold joint 14 to center line, thereby can make axle mold joint 14 maximum apart from the distance of the inwall of axis hole 2, guarantee quality of fit.
Wherein, dodge plane 15 and be two and two and dodge the relative both sides that plane 15 lays respectively at axle main body 11, dodge plane 15 and be symmetrical arranged with respect to axle 1 line of axle main body 11 for two, can make to be like this formed on axle mold joint 14 in axle main body 11 more effectively with the inwall of axis hole 2 away from, improve the quality of fit of axle 1 and axis hole 2, reduce friction, make axle 1 more stable with coordinating of axis hole 2.
In embodiments more of the present utility model, axle 1 also comprises upper stop block 12 and the lower stop block 13 that is located at respectively axle main body 11 top and bottom, as shown in Fig. 1, Fig. 3, Fig. 5 and Fig. 6.Wherein, the radial dimension of upper stop block 12 and lower stop block 13 is all greater than the diameter of the inwall of axis hole 2, upper stop block 12 and lower stop block 13 difference backstops are at upper surface and the lower surface of axis hole 2, that is to say, upper stop block 12 is the upper surface at axis hole 2 for backstop, lower stop block 13 is the lower surface at axis hole 2 for backstop, can effectively axle main body 11 be limited in axis hole 2 like this, guarantees the installation stability of axle main body 11.
Further, axle 1 is provided with along axle 1 to extending and the unlimited U-groove bevel 17 in upper end, that is to say, U-groove bevel 17 is upward through stop block 12, because the radial dimension of upper stop block 12 is greater than the diameter of the inwall of axis hole 2, by form the unlimited U-groove bevel in upper end 17 on axle 1, axle 1 is being installed to axis hole 2 when interior like this, distortion when U-groove bevel 17 is stressed, the radial dimension of upper stop block 12 diminishes, be conducive to axle 1 through axis hole 2, realize easily the installation of axle 1 and axis hole 2.After having assembled, upper stop block 12 distortion recover, and backstop is on the upper surface of axis hole 2.
According to the axle 1 of the utility model second aspect electric component, comprise: axle main body 11, in axle main body 11, have axle 1 to axle mold joint 14, in axle main body 11, be formed with mold joint intersects and dodge plane 15, axle main body 11 is provided with at least two along axle 1 to the isolated circular groove of direction.According to axle 1 of the present utility model, can be engaged in better in axis hole 2, make the axle mold joint 14 of axle main body 11 and the inwall of axis hole 2 away from, improve the installation precision of axle 1 and axis hole 2, reduce the noise that axle 1 rotates in axis hole 2, make axle 1 stable with coordinating of axis hole 2, extend life of product, improve the quality of products.
Axle main body 11 is provided with two along axle 1 to the isolated circular groove of direction, and two circular grooves comprise first circular groove 161 relative with hole mold joint 21 and for storing the second circular groove 162 of lubricant oil.Can reduce the friction between axle 1 and axis hole 2 by lubricant oil thus, improve product working life and quality of product.
In the description of this specification, the description of reference term " embodiment ", " some embodiments ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiments or example.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present utility model and aim, can carry out multiple variation, modification, replacement and modification to these embodiments, scope of the present utility model is limited by claim and equivalent thereof.
