[45] outer shroud 52 close-fittings of described ball bearing are in the inside of described crown member 26, and link to each other with described crown member rotation.
[46] stacked described two ball bearings are axially separated a little distance, but this distance by the elastic material of a deformation, for example rubber or that flexible material is made thin packing ring 58 is determined, puts between the outer shroud 52 of described two ball bearings between described thin packing ring.
[47] outer shroud 52 of Xia Fang described ball bearing is bearing on the convex shoulder of described crown member 26 internal surfaces, and a nut 60 screws are fixed on the top of described crown member 26 and are bearing on the outer shroud 52 of described ball bearing of top, the screw of described nut 60 is fixed the feasible axial distance that can regulate between described two ball bearings, and therefore regulates the running clearance of described kneecap shape body.
When [48] putting into practice, at first to greatest extent described nut 60 screws are fixed on the top of described crown member 26, with the gap that promotes mutually between the lasso of the described ball 40 of basic elimination to produce, the lasso of described ball 40 is bearing on the described kneecap shape body, then, unscrew described nut 60 a little, to guarantee the running clearance on the described kneecap shape body, described gap for example is included between 0.05 to 0.1mm, and make described relatively crown member 26 rotations of described nut 60 fixing in any suitable manner, for example pass through the plastic deformation of the thin periphery of this nut.
[49] modification ground, described two ball bearings are installed in the lasso, and the top of described lasso comprises protruding pin, and described protruding pin presses down (rabattus), in order to described ball bearing is remained on the good position, this position has the good needed spacing of operation of described kneecap shape body.
[50] in addition, put between described metal group member between advantageously design flexibility or that analog material is made noise-proofing cushion block, to reduce the noise of high speed operation.
When [51] moving, described axis body 20 is driven around described point 22 high speed oscillatory movements, described axle can not rotate around its axis 24, with known mode of those skilled in the art and for example described mode of aforementioned document WO2004/012851, by device described platen is linked to each other with described crown member 26 or with the fixed frame of described instrument, forbid that described table top 10 is around this axis rotation.
High speed translation when [52] described ring 46 makes described axis body 20 oscillatory movements with respect to described kneecap shape body 30 with respect to the high speed rotating of the outer shroud 52 of described ball bearing, described kneecap shape body rotates fixing on described axis body 20, and described outer shroud 52 rotates fixing on described crown member 26.
[53] allow to improve described axis body 20 between the angle wheel shaft trip on both sides, a neutral position according to device according to the present invention, shown in embodiment in, between this angular travel can be 8 ° or more.Determine on the one hand between this angular travel, and determine by the axial distance between two lassos of described ball 40 on the other hand by the axial dimension of the described kneecap shape body size of the segment part of the axis of described axis body 20 (or along).With respect to file WO 2004/012851 described mode of execution, allow the external diameter of described table top 10 to reduce half between described double angular travel, guarantee the alternately identical translation stroke of the pipe fitting 12 of curvilinear motion simultaneously fully, and therefore guarantee the identical fast vibration performance and the grinding that is contained in the Biosample in the described pipe fitting of described pipe fitting 12.
[54] diameter of described table top 10 reduces to make its weight to reduce, and drives the required energy minimizing of this table top.
[55] in addition, the guiding device according to axle 20 of the present invention has many advantages:
[56] can use on the market a kneecap shape body 30, and described annular groove 44 by micron order " routine " fine finishing on the interior ring of on the market standard ball bearings, in described toroidal cavity 44, described ball 40 is directed being bearing on the described kneecap shape body 30.
[57] therefore, guiding device according to the present invention is simple relatively with cheaply.Have again, the running clearance can regulate of described kneecap shape body 30, this makes and can guarantee that the optimization with the kneecap shape body on the market of not knowing accurate dimension in theory moves, and the guide recess 44 that does not need to process the described ball 40 of very high degree of precision.
[58] as beginning pointed mistake, the bearing of the dribbling face supporting surface that described device is related to and ball bearing can be conversely, and the bearing of described dribbling face supporting surface is between described fixed support and is installed in ball bearing on the described axis body 20.
