Description
Vorrichtung zum Vermindern der zwischen zwei Gleitbahnen von Werkzeugmaschinen
auftretenden Reibung
Zur Bekämpfung dieses Mißstandes sind bereits verschiedene Kunstgriffe angewendet worden. Man hat den Tisch auf Sätzen von beweglichen Kugeln oder Rollen gelagert, die zwischen den auf der Unterseite des Tisches und den auf der Oberseite des Rahmens oder Bettes ausgebildeten Gleitbahnen laufen. Der Erfolg ist ausgezeichnet, was die Verminderung der Reibungen und die Empfindlichkeit 1>1i Feineinstellungen betrifft. Jedoch treten andere Mängel in Erscheinung; die Führung ist nicht "ciliigend wirksam für den Fall, daß starke Drucke (stier zur Bewegungsrichtung auftreten.There are already various tricks to combat this maladministration been applied. You have the table on sets of movable balls or rollers stored between the ones on the bottom of the table and the ones on the top of the frame or bed trained slideways run. The success is excellent what the reduction of the friction and the sensitivity 1> 1i fine adjustments regards. However, other shortcomings appear; the leadership is not "ciliing" effective in the event that strong pressures occur (towards the direction of movement.
Man hat auch einzeln durch Federn gespannte Entlastungsrollen an dein Tisch befestigt, die einen Teil des Gewichtes des Tisches aufnehmen und dessen Pcibung auf dem Rahmen oder Bett verriiigern sollen. Diese Lösung ist nicht zufriedenstellend, insoweit es sich um die Verschiebung schwerer Massen handelt, da sich die Einzeleinstellung (ler Federn, deren Spannung sich sehr vcr-:indcrlichen Gewichten, Eigengewicht des Tisches plus Gewicht des zu bearbeitenden Stückes, anpas,#eii nitil;, schwer verwirklichen l;ißt und da (sie 1, edern, u111 stark genug zu sein, sehr sperrig werden.You also have relief rollers on your individually tensioned by springs Table attached, which take up part of the weight of the table and its Pcibung on the frame or bed. This solution is not satisfactory, as far as it is about the displacement of heavy masses, since the individual setting (For springs, the tension of which is very different: indigenous weights, dead weight of the Table plus weight of the piece to be worked on, anpas, # eii nitil ;, difficult to realize l; eats and because (they 1, edern, u111 to be strong enough, become very bulky.
Die Erfindung beseitigt die vorstehend angegebenen Mängel. Sie betrifft eine .Maschine init einem Gestell oder Bett, einem auf mindestens einer Gleitbahn desselben beweglichen Gleitblock oder -Schlitten und mindestens einer Vorrichtung zur Entlastung der Gleitballil von dem Gewicht des Gleitblocks oder -schlittens.The invention overcomes the deficiencies noted above. She concerns a .machine with a frame or bed, one on at least one slide the same movable slide block or carriage and at least one device to relieve the sliding ballil from the weight of the sliding block or slide.
Dieselfaschine ist gekennzeichnet durchfolgende Merkmale: Die erwähnte Vorrichtung weist mindestens <°iiien Satz Rollen auf, die in zwei übereinan(IerIiegendcil Reihen zueinander versetzt angeordnet sind; die Achsen der Rollen sind an den Ecken von nebeneinandergestellten bzw. ancinandergefiigten Dreiecken angeordnet; (iiejenigen Seiten dieser Dreiecke, die eine Rolle mit den beiden benachbarten Rollen der anderen Reihe ver-binden, sind durch Streben oder Laschen gebildet, (sie nliteiilander auf den Achsen der Rollen gelenkig verbunden sind; die letzte Strebe oder Lasche ist an einem festen Punkt des Gleitblocks oder -Schlittens an( elenkt und die erste Strebe oder Lasche ist ebenfalls an dem Gleitblock oder -Schlitten jedoch unter Vermittlung einer Spannvorrichtung angelenkt; die Rollen der oberen Reihe stützen sich gegen den Gleitblock oder -sclllitten ab und diejenigen der unteren Reihe laufen auf dem Gestell oder Bett.Diesel machine is characterized by the following features: The device mentioned has at least one set of rollers, which are arranged in two superimposed rows offset from one another; the axes of the rollers are arranged at the corners of triangles placed next to one another or attached to one another; (those sides of these triangles comparable a role with the two adjacent rollers of the other row of binding, are formed by struts or tabs (they are nliteiilander hinged on the axes of the rollers, the last strut or tab is at a fixed point of the sliding block or - Slide on (articulates and the first strut or bracket is also articulated to the slide block or slide, but with the intermediation of a tensioning device; the rollers in the upper row are supported against the slide block or slide and those in the lower row run on the frame or bed .
