Description

Einrichtung für Auswuchtvorrichtungen; insonderheit von Schleifscheiben auf ihren Wellen. Die Erfindung betrifft Einrichtungen an Maschinen mit schnellaufenden Wellen, besonders Schleifmaschinen, zum bequemen und- raschen Auswuchten der Schleifscheiben während des Betriebes, und zwar namentlich in der Ausbildung, wo die Schleifscheiben zum Ausbalancieren nicht mehr von den Schleifspindeln abgenommen zu werden brauchen, sondern (wie nach Patent 355 592) während des Laufes verstellbare Unbalancegewichte außerhalb der Schleifscheiben oder deren Hülsen durch Anhalten eines Handknopfes über ein damit in Verbindung stehendes Verstellungsgetriebe sich so einstellen, daß die Unbalancen der Ausw uchtapparate ein Äquivalent gegenüber der Unbalance der Schleifscheiben bilden.Device for balancing devices; in particular of grinding wheels on their waves. The invention relates to devices on machines with high-speed Shafts, especially grinding machines, for convenient and quick balancing of the grinding wheels during operation, namely during training, where the grinding wheels no longer need to be removed from the grinding spindles for balancing, but (as in patent 355 592) imbalance weights adjustable during the run outside of the grinding wheels or their sleeves by holding a hand knob above a related adjustment gear set so that the Imbalances in the balancing devices are equivalent to the imbalance in the grinding wheels form.

Die Erfindung besteht nun in einer Einrichtung, durch die die mangelnde Ausbalancierung durch die dabei auftretenden Vibrationen und die Notwendigkeit einer Ausbalancierung leicht kenntlich gemacht wird. Zu diesem Zwecke werden die Lager der Schleifspindel abgefedert und die Federkonstanten so gewählt, daß die größten Schwingungen bei Betriebsdrehzahl auftreten. Durch ungleich starke Abfederung der beiden Lager kann die Einrichtung bei doppelscheibigen Maschinen noch dahingehend verbessert werden, daß die beiden Scheiben je für sich getrennt, ohne jeweilige Beeinflussung der gegenüberliegenden Scheibe, ausbalanciert werden können.The invention now consists in a device through which the lack of Balancing through the vibrations that occur and the need for a Balance is easily identified. For this purpose, the bearings the grinding spindle sprung and the spring constants selected so that the largest Vibrations occur at operating speed. Due to the unevenly strong cushioning of the Both bearings can still be used by the device in double-disc machines be improved that the two disks are each separately, without a respective Influencing the opposite disc, can be balanced.

Damit die Scheiben nicht dauernd in Resonanz laufen, sind die Lager während der Benutzung der Maschine starr einzustellen, was durch Gegendruckschrauben o. dgl. geschehen kann.The bearings are designed to prevent the disks from constantly running in resonance to be set rigidly while the machine is in use, which can be achieved by means of counter pressure screws o. The like. Can happen.

Auf einem Untergestell a nach Abb. i ist eine Welle, an deren Enden Schleifscheiben aufgesetzt sind, in den Lagern b gelagert. Außerhalb der Scheiben sind mit den Wellenenden die Ausbalanciervorrichtungen c verbunden, die während des Laufes durch Anhalten der Handknöpfe d betätigt werden können. Die Lager b sind an dem Untergestell a auf Stahlfedern oder Gummiplatten usw. schwingbar befestigt. Durch Druckschrauben e kann während der Benutzung der Schleifsteine die Schw ingbarkeit hergestellt oder aufgehoben werden. Werden an den Maschinen Vibrationen gespürt, so werden 'die Druckschrauben e gelöst, und die durch Unbalancen hervorgerufenen Schwingungen können sich besser ausbilden und treten dadurch auch deutlicher in Erscheinung. Die in den Ausbalanciervorrichtungen enthaltenen Unbalancen werden in bekannter Weise nach Bedarf vergrößert bzw. verkleinert durch Verdrehung um die Schleifwellenachse, so daß sich eine der Unbalance der Schleifscheibe entsprechende Gegenunbalance bildet, infolge der die Welle und die Scheibe ruhig läuft. Bei doppelseitigen Schleifmaschinen wird die Methode an beiden Scheiben angewendet. Daraufhin werden die Lager durch Anziehen der Schrauben e wieder starr mit dem Untergestell verbunden. Abb.2 zeigt eine Einscheibenmaschine.On a base a according to Fig. I is a shaft, at the ends Grinding wheels are put on, stored in bearings b. Outside the panes the balancing devices c are connected to the shaft ends, which during the barrel can be operated by holding the hand buttons d. The bearings b are attached to the underframe a on steel springs or rubber plates, etc. swingable. Pressure screws can be used to increase the swingability while the grinding stones are in use be established or canceled. If vibrations are felt on the machines, so 'the pressure screws e are loosened, and those caused by imbalances Vibrations can develop better and thus also occur more clearly Appearance. The imbalances contained in the balancers become enlarged or reduced in a known manner as required by rotating around the Grinding shaft axis, so that there is a corresponding to the imbalance of the grinding wheel Counter imbalance forms, as a result of which the shaft and the disc run smoothly. With double-sided Grinding machines, the method is used on both discs. Thereupon be the bearings are again rigidly connected to the subframe by tightening the screws e. Fig.2 shows a single disc machine.
