Cutting tool 9 is housed on replaceable bearing 1., first can be by pedestal 2 with its bottom section 2.1 in order to assemble fixed pedestal 2
It is fixed on the outer surface of rotatingcylindrical drum 2.2, such as by being welded and fixed (only local in figure 3 to show).On the base 2 may be used
Replaceable bearing 1 is assembled in a manner of by being described in further detail below.Replaceable bearing 1 finally installs cutting tool 9, cutting
Cutter 9 is mounted in the independent component on replaceable bearing 1, is, for example, specifically circle handle chisel, such as Fig. 1 into Fig. 3 institute
As showing.In job run, rotatingcylindrical drum 2.2 is allowed to rotate by appropriate drive device, so as to which cutting tool 9 is along work
Industry direction M contacts with ground to be processed and corresponding ground-to-ground face carries out scarifying, mixing, crushing etc..
It is crucial for one in the mounting system 100 of ground cutting tool and for the utility model in essence
Element is annular element 50, and it includes outer surface 50.1, and inner surface 50.2, locating surface 50.4, through slot 50.3, material is steel
System, there are enough intensity, toughness, elasticity.The vital point of the annular element is, as shown in Fig. 1,2,7, the side according to arrow D4
Assembled to being fitted into annular element 50 in the hole shape chamber 27 of pedestal 2, then by replaceable bearing 1 along arrow D3 directions in pedestal
On 2, finally, bolt 3 is passed through to the stepped hole 26 of pedestal 2 along arrow D5 directions, m rotates to replaceable bearing along direction of rotation
In 1 internal thread hole 14.In the presence of the pretightning force F of bolt 3, as shown in Fig. 3,4,7,10, each element before being screwed for bolt
Initial positional relationship.
The inner surface 50.2 of annular element 50 is cone, there is diameterDiameterAngle [alpha] 1, replaceable bearing 1 are consolidated
The taper anchor ring 11.1 determined on connecting portion 11 has diameterDiameterAngle [alpha] 3, and
Angle [alpha] 1=α 3, so the taper anchor ring being fixedly connected in portion 11 of the inner surface 50.2 of annular element 50 and replaceable bearing 1
11.1 can realize and be brought into close contact slip.
Further continue swivel bolt 3, then replaceable bearing 1 can be along direction D3 and along the inner surface of annular element 50
50.2 slide, and now, because annular element 50 is steel, leave a through slot 50.3, there is certain intensity, toughness, elasticity, and
And the diameter on one segment length C, by diameterTo diameterIt is gradually reduced, it should be apparent that, annular element 50 can quilt
The diameter being fixedly connected in portion 11 of replaceable bearing 1Expanded, and expanded along direction D1, D2, due to annular element
50 outer surface diameter isAndSo the outer surface of annular element 50 and base aperture shape chamber 27 it
Between uniform gap X be present, when the outer surface diameter of annular element 50It is expanded to and the diameter of base aperture shape chamber 27It is equal
When, as shown in Fig. 6 Figure 10, i.e.,Uniform gap X=0, then locking terminal surface 3.3 and the pedestal of bolt 3
Step surface 28.1 is brought into close contact, and shows that bolt 3 has screwed.Then the outer surface 50.1 of annular element 50 and base aperture shape chamber 27 are tight
Closely connected conjunction;
The inner surface 50.2 of annular element 50 and the taper anchor ring 11.1 being fixedly connected in portion 11 of replaceable bearing 1 are close
Fitting;The locating surface 50.4 of annular element 50 is brought into close contact with base step face 27.4.Synchronous, the support of replaceable bearing is bent
Face 12.1,12.2 is identical with 23.1,23.2 liang of two radius of carrying curved surface of pedestal respectively, so SURFACES MATCHING can be brought into close contact.
The carrying curved surface 22.1 with pedestal, 22.2 two radius are identical respectively for the support curved surface 40.1,40.2 of replaceable bearing, so curved surface
Matching can be brought into close contact, and all of above fitting is mechanical interference mode.
The difference of embodiment two, the present embodiment and embodiment one is:The component inner surface 50.2 of the annular element 50
For the face of cylinder, member outer surface 50.1 is circular conical surface, and the outer surface of annular protrusion is the shape size with component inner surface 50.2
The face of cylinder corresponding to matching, the inner surface that hole shape chamber 27 contacts with annular element 50 are and the shape size of member outer surface 50.1
Circular conical surface corresponding to matching.
The diameter at the maximum end of the circular conical surface of the hole shape chamber 27The member outer surface 50.1 of annular element 50 is most
General goal diameterThe diameter of the smallest end of the circular conical surface of hole shape chamber 27The diameter of component inner surface 50.2 of annular element 50The diameter of outer surface 11.1 of annular protrusionBetween relation be:
According to the published mounting system for ground cutting tool, its replaceable bearing is fixedly connected with portion and pedestal
Upper hole shape chamber coordinates without the assembling that is rigidly connected, and on plane A, replaceable bearing has single-degree-of-freedom B to be not affected by limitation, i.e.,
Replaceable bearing has the activity of displacement in arrow direction, then in practice of construction in use, replaceable bearing is in height
Under frequency, large impact power and the working condition of judder, the possibility for occurring loosening, coming off greatly increases, the utility model
As shown in figure 9, for the free degree B of the replaceable bearing 1 in the mounting system 100 of ground cutting tool in the direction of the arrow by ring
Shape part 50 and base aperture shape chamber 27 are limited, and so, just thoroughly solve replaceable bearing 1 and occur pine in actual applications
It is dynamic, and the phenomenon eventually fallen out.
It should be appreciated that although the present specification is described in terms of embodiments, not each embodiment only includes one
Individual independent technical scheme, this narrating mode of specification is only that those skilled in the art will should say for clarity
Bright book is as an entirety, and the technical solutions in the various embodiments may also be suitably combined, and forming those skilled in the art can be with
The other embodiment of understanding.
