Description

Tonarmlagernng für Sprechmaschinen. Der Erfindungsgegenstand gehört ztii7 Klasse der Tonarmlagerungen für Sprechmaschinen, bei «-elchen der Tonarm in wagerechter Ebene schwenkbar auf Kugeln gelagert ist.Tonearm bearings for speaking machines. The subject of the invention belongs ztii7 class of tonearm bearings for speaking machines, with «-elchen the tonearm in horizontal plane is pivotally mounted on balls.

Für solche Tonarnilagerungen hat nian schon vorgeschlagen, den drehbaren Toliarn: finit einem Ausgleichsgewicht zu versehen, derart, daß der Schwerpunkt des Tonarme; liebst Ausgleichsgewicht ganz oder nahezu in die Drehachse des Tonarinstutzens fällt.For such tonar mountings, nian has already suggested the rotatable one Toliarn: finite to be provided with a balance weight, such that the center of gravity of the tonearms; prefer the balancing weight completely or almost in the axis of rotation of the Tonarinstutzens falls.

Der Erfindungsgegenstand unterscheidet sich voll diesen bekannten Vorschlägen dadurch, daß der zur Abstützung des Tonarme.; dienende Kugellagerring exzentrisch ausgebildet ist und dadurch gleichzeitig als Gewichtsausgleichsring dient, so daß kein besonderes Organ am Tonarm mit einem besonders aufzuschiebenden Ausgleichsgewicht vorgesehen werden muß.The subject of the invention differs completely from these known ones Suggestions by the fact that the to support the tonearms .; serving ball bearing ring Is designed eccentrically and thereby at the same time as a weight compensation ring serves, so that no special organ on the tone arm with a special postponement Balance weight must be provided.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. i ist der Tonarm, dessen Stutzen :2 im Lagerstutzen 3 drehbar gelagert ist. Der Lagerstutzen 3 ist in der Decke 4 des Sprechniaschinengehäuses befestigt und mit zwei Kugelstützringen, einem oberen (7) und einen] unteren (6) versehen, in deren Rillen die in Dralitkäfigen$ gelagerten Kugeln? laufen. Der Stutzen 2 ist nun unmittelbar (itirch eint Platte y an den zur Drehachse exzentrisch gelagerten Gewichtsausgleichring befestigt. Dieser weist einen nach innen vorspringenden Flansch i i auf, dessen Stirnflächen Gegenlager für die Kugeln 7 bilden, so daß also der Tonarin 1, 2 mittels dieses Kugelstützringe.. gleichzeitig ausbalanciert wird; er ist infolgedessen leicht drehbar, und jegli--lie Beanspruchung der Schallrille beim Verschwenken de: Tonarmes ist aH-geschlossen.The subject of the invention is shown in the drawing, for example. i is the tonearm whose socket: 2 is rotatably mounted in the bearing socket 3. Of the Bearing stub 3 is fastened in the ceiling 4 of the talking machine housing and with two ball support rings, an upper (7) and a] lower (6), in which Do the balls, which are stored in Dralit cages, have grooves? to run. The nozzle 2 is now immediate (Itirch unites plate y on the weight compensation ring, which is eccentrically mounted to the axis of rotation attached. This has an inwardly projecting flange i i, whose End faces form counter bearings for the balls 7, so that the Tonarin 1, 2 by means of this ball support ring .. is balanced at the same time; it is therefore easy rotatable, and any stress on the sound groove when swiveling the tonearm is aH-closed.
