Description
Technical field
The present invention relates to a kind of according to the spinning ingot of claim 1 preamble or the spindle upper section of twisting spindle.
Background technology
Can know spinning ingot or twisting spindle from DE 19638378A1 according to claim 1 preamble, wherein, the spindle upper section of being made up of at least two parts is connected by the shrink-fit or the interference fit based on the interference fit of these two parts of spindle axis and wharve or pipe carrier (tube carrier).The matching surface that corresponds to each other extends so that realize interference fit on a zone according to their structure, below should represent with lap in the zone.
In being connected of spindle axis and wharve or pipe carrier, in order to realize and the through hole flush arrangement of the wharve or the pipe carrier that are used to receive spindle axis that spindle axis is directed vertically with respect to them.Like this, guaranteed that at the spindle run duration actual motion value (true running value) is low as far as possible, and therefore guaranteed that the disequilibrium of spindle upper section is lower.But this connection has shortcoming, that is, because radial oriented component affacts on the spindle axis on the spindle upper section (for example in transportation or process hand-manipulated can this thing happens), the actual motion value of spindle upper section increases and also surpasses tolerable limit.Even under the situation of low load, radial component also has stronger influence along with the relation between the length of spindle axis length and overlapping region.The imbalance of spindle upper section is accompanied by the increase of actual motion value and increases, and this causes the increasing the weight of of wearing and tearing of higher bearing load and associated bearings.
The increase of actual motion value results from the stress distribution in the interference fit.In the local part of the lap that forms by two pressure surfaces, owing to last axle head produces moment of flexure with respect to the radial load of wharve; This part part begins to extend along the axis of lap the direction extension of (extension) from the end face towards spindle upper section of wharve or pipe carrier.Act on towards the moment of flexure of loading direction one side (just radial component acts on the side on the spindle axis) and cause that spindle axis breaks away from wharve a little.On the side of spindle axis away from imposed load, moment of flexure causes spindle axis is pressed into the matching surface of wharve or pipe carrier.The stress distribution of this load is enough to surpass some millimeters along axially entering contraction or interference fit.When radial component disappears,, thereby stoped axle to turn back to its original position fully owing to the stiction that in the zone of shrink-fit or interference fit, exists than the big manyfold of force of sliding friction.Therefore cause the actual motion value to increase, thereby make uneven the increase.
Summary of the invention
The objective of the invention is the shortcoming of roughly avoiding above-mentioned connection and being brought in the mode of economy from above-mentioned prior art.
The spindle upper section of the feature by having claim 1 is realized above-mentioned purpose.
Favourable structure of the present invention is the theme of dependent claims.
According to claim 1, propose the local part of matching surface in the fringe region of lap formed interference fits.Owing in the fringe region of lap, described local part is formed interference fits, compare with other zones (in this zone, being interference fit) of lap, the stiction of described local part reduces, thereby when cancelling the radial component that acts on the spindle axis, can compensate motion, this compensating motion roughly makes spindle axis return its original position with respect to the wharve location.The feasible value that can keep like this, the actual motion value substantially.In the prior art, because stiction goes out manyfold than force of sliding friction is big, stop spindle axis to slide to turn back to the effect of original position thereby produce; According to the present invention, by the simplest means of structure this effect is minimized in the mode of economy.
Described local part is preferably arranged for the top near described spindle axis.For this reason, this part part can be from the end face towards described spindle axis top, the extending axially along described spindle axis of described at least one part.In manual operations or when transporting this spindle upper section, when particularly the top of described spindle axis was subjected to load, the component that this load radially acts on can cause effect mentioned above.Owing to being furnished with the local part that is positioned at transitional region according to the present invention, therefore the position of the load effect that causes at radial component with maximum negative effect minimizes the load influence.
Specifically, the lap of matching surface wherein exists the zone of interference fits can be at least part along spindle axial axially extended 80%.
In a preferred embodiment, can depart from interference fit a little by the external diameter that makes spindle axis and form described local part.The internal diameter of through hole that perhaps, can be by making described at least one part departs from interference fit a little and forms described local part.For this reason, departing from of the described part of part at least can be about 0.01mm to 0.1mm.The order of magnitude that departs from depends on the diameter of spindle axis and through hole to a great extent.
Description of drawings
To introduce the present invention in further detail by means of embodiment shown in the drawings below, in the accompanying drawings:
Fig. 1 represents to be equipped with on it phantom of first embodiment of the spindle axis of wharve;
Fig. 2 represents the phantom according to second embodiment of the spindle axis of Fig. 1.
The specific embodiment
Fig. 1 represent to spin spindle upper section 1 of ingot or twisting spindle, this spindle upper section comprise spindle axis 2 and are arranged at least one part on the spindle axis 2 that this part specifically is wharve 3 or pipe carrier (not shown).Wharve 3 is used herein to and drives spindle upper section 1, and pipe carrier is used to receive winding reel or coiling bobbin.This pipe carrier for example can be made into aluminum component.
Wharve 3 has through hole, and spindle axis 2 is guided and passes this through hole.This structure also can correspondingly be used for having the layout of pipe carrier on spindle axis 2.Can fastening wharve 3 or pipe carrier by shrink-fit or interference fit.Shrink-fit or interference fit belong to interference fit, can realize intending the radial and axial fixing of interconnective part by this interference fit.
For this reason, the through hole of spindle axis 2 and wharve 3 is provided with corresponding matching surface 6,7.Here the lap 4 of the matching surface between spindle axis 2 and wharve 3 or the pipe carrier 6,7 is present in in axial direction the shrink-fit or the zone of interference fit.Owing between by shrink-fit or interconnective two parts of interference fit, static friction takes place, as mentioned above, thereby prevented axially or radially relative motion and relevant therewith rough sledding.
As shown in Figure 1,4 of the laps that carries out shrink-fit or interference fit of matching surface 6,7 are partly in the extension that extends axially of wharve 3.Between spindle axis 2 and wharve 3, be formed with local part 5 vertically, in this part part, so select the diameter of spindle axis 2 and wharve 3, make the matching surface 6,7 of local part 5 be designed to interference fits.According to Fig. 1, the part of the external diameter by spindle axis 2 attenuates and forms local part 5.Interference fits in local part 5 is meant, is bringing owing to radial component under the situation of load, and spindle axis 2 and wharve 3 are realized reversible slip in local part 5.
According to optional embodiment, as shown in Figure 2, increase the aperture of wharve 3 on spindle axis 2 external diameters by part and form local part 5.According to the structure of first embodiment, the part in above-mentioned aperture in the case increases within the interference fits acceptable margin of tolerance.
The common ground of all embodiment is, because the interference fits in local part 5 (zone of crooked gradient maximum), the ratio of static friction in local part 5 reduces to some extent than the ratio in other zones of lap 4, make in local part 5, to exist under the situation of load, between wharve 3 and spindle axis 2, relative motion can take place.Because thereby spindle axis 2 can retreat in this part part 5 when radial component disappears and slide to its original position, so this makes the adverse effect minimum that produces in the connection of prior art.
The little deviation of the external diameter of spindle axis and/or the internal diameter of through hole is about 0.01mm to 0.1mm.Here, the zone of interference fit at least wharve 3 or pipe carrier along spindle axis 2 axially extended 80% on extend.
