Description
Technical field
The utility model relates to excavator support chain wheel field, refers more particularly to a kind of quick position Anti-loose holder sprocket wheel of excavating machine.
Background technology
This type of installation portion existing is the holder sprocket wheel of optical axis at present, assembling at bracket is often need to regulate the position between itself and bracket along holder direction of principal axis manually, employing installation portion is the holder axle of optical axis, installation is that easily the axial location of holder for regulating sprocket wheel is often wanted in location, not only it is installed and bothers man efficiency low, light shaft design simultaneously, little at the friction drag of its contact site, easily producing under the effect of various mechanical vibration asks sprocket wheel and bracket to loosen the phenomenon even come off, and affects its in-use performance.
Utility model content
The quick position Anti-loose holder sprocket wheel of the excavating machine that the purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of structure simple, practical.
The utility model realizes in the following way:
A kind of quick position Anti-loose holder sprocket wheel of excavating machine, it is characterized in that: comprise holder sprocket wheel wheel body 1, holder axle 2, the middle part of described holder sprocket wheel wheel body 1 is through hole 11, its two ends, left and right are respectively equipped with left stepped hole 12 and right stepped hole 13, and described left stepped hole 12 and right stepped hole 13 communicate with through hole 11 respectively; A deep groove ball bearing 3 is connected in described left stepped hole 12 and right stepped hole 13; The left end of described holder axle 2, successively through the deep groove ball bearing 3 in right stepped hole 13 and the deep groove ball bearing 3 in left stepped hole 12, asks the left end of axle 2 to be fixed by jump ring 4 simultaneously; The right side of described holder axle 2 is positioned at outside holder sprocket wheel wheel body 1, and described holder axle 2 is rotatable relative to holder sprocket wheel wheel body 1; Be provided with outside framework oil seal 5 and right end cap 6 in described right stepped hole 13, described outside framework oil seal 5 and right end cap 6 are arranged on holder axle 2, and between the deep groove ball bearing 3 of outside framework oil seal 5 in right end cap 6 and right stepped hole 13; Be provided with left end cap 7 in described left stepped hole 12, described left end cap 7 is positioned at the left side of the deep groove ball bearing 3 of left stepped hole 12; The right-hand member of described holder axle 2 is provided with more than one circular arc positioning groove 21.
The beneficial effects of the utility model are: adopt the right-hand member turning two sections of circular arc positioning grooves at holder axle, when installing with supporting bracket, only need respectively squeeze at circular arc positioning groove the quick position that a locating dowel pin realizes holder sprocket wheel wheel body and bracket respectively, the various vibrations that simultaneously can prevent again excavating machine from producing in the course of the work, the phenomenon of holder sprocket wheel wheel body and bracket generation loose or dislocation, can make like this holder sprocket wheel wheel body firm be fixed on chassis walking frame, ensure that it is in use reliable and stable.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
Detailed description of the invention
Now by reference to the accompanying drawings, the utility model detailed description of the invention is described in detail in detail:
As shown in Figure 1, a quick position Anti-loose holder sprocket wheel for excavating machine, comprises holder sprocket wheel wheel body 1, holder axle 2, and the middle part of holder sprocket wheel wheel body 1 is through hole 11, its two ends, left and right are respectively equipped with left stepped hole 12 and right stepped hole 13, and left stepped hole 12 and right stepped hole 13 communicate with through hole 11 respectively; A deep groove ball bearing 3 is connected in left stepped hole 12 and right stepped hole 13; The left end of holder axle 2, successively through the deep groove ball bearing 3 in right stepped hole 13 and the deep groove ball bearing 3 in left stepped hole 12, asks the left end of axle 2 to be fixed by jump ring 4 simultaneously; The right side of holder axle 2 is positioned at outside holder sprocket wheel wheel body 1, and holder axle 2 is rotatable relative to holder sprocket wheel wheel body 1; Be provided with outside framework oil seal 5 and right end cap 6 in right stepped hole 13, outside framework oil seal 5 and right end cap 6 are arranged on holder axle 2, and between the deep groove ball bearing 3 of outside framework oil seal 5 in right end cap 6 and right stepped hole 13; Be provided with left end cap 7 in left stepped hole 12, left end cap 7 is positioned at the left side of the deep groove ball bearing 3 of left stepped hole 12; The right-hand member of holder axle 2 is provided with more than one circular arc positioning groove 21.
The utility model deep groove ball bearing 3 adopts interference fit to be pressed in holder sprocket wheel wheel body 1, and right end cap 6 adopts interference fit to be pressed into holder sprocket wheel wheel body 1, plays sealing function; Outside framework oil seal 5 and right end cap 6 are pressed into holder sprocket wheel wheel body 1 through holder axle 2, and wherein the endoporus of outside framework oil seal 5 and its corresponding position ask the external diameter of axle 2 to be interference fit, play sealing function.
The utility model adopts the right-hand member turning two sections of circular arc positioning grooves 21 at holder axle 2, when installing with supporting bracket, only need respectively squeeze at circular arc positioning groove 21 quick position that a locating dowel pin realizes holder sprocket wheel wheel body 1 and bracket respectively, the various vibrations that simultaneously can prevent again excavating machine from producing in the course of the work, the phenomenon of holder sprocket wheel wheel body 1 and bracket generation loose or dislocation, can make like this holder sprocket wheel wheel body 1 firm be fixed on chassis walking frame, ensure that it is in use reliable and stable.
