Description

Maschineller Handhammer mit elastischer Rückstoßdämpfung Wenn man einen Arbeiter, der einen maschinellen Handhammer bedient, während der Arbeit beobachtet, so bemerkt man, daß sein Körper dauernd heftig erschüttert wird. Die Ursache dieser Erschütterung findet man in den starken Vibrationen des Hammers, die sich unmittelbar auf den Körper des Arbeiters fortpflanzen und hier allmählich schwere, oft unheilbare Gesundheitsstörungen und Veränderungen hervorrufen. Der Behebung dieses Cbelstandes soll die vorliegende Erfindung dienen.Mechanical hand hammer with elastic recoil damping If you observes a worker using a mechanical hand hammer while he is working, so one notices that his body is constantly being violently shaken. The cause of this One finds shock in the strong vibrations of the hammer, which are immediate propagate on the body of the worker and here gradually heavy, often incurable Cause health disorders and changes. The elimination of this problem is intended to serve the present invention.

Die Ursache der Vibrationen des Hammers ist darin zu suchen, daß bei allen maschinellen Hämmern das treibende Medium beim Hinundherschieben des Schlagkolbens sich gegen den Zylinderkörper stützt und so hei jedem Schlage mit demselben Stoße, den der Schlagkolben erfährt, auch nach rückwärts gegen die Zylinderstirnwand wirkt. Jedoch wird die Heftigkeit des Stoßes gemildert durch das größere bremsende Gewicht des Zylinders im Verhältnis zu dem des Schlagkolbens; die Stärke des Stoßes bei beiden.verhält sich umgekehrt wie die Größe der Gewichte.The cause of the vibrations of the hammer is to be found in the fact that at All mechanical hammers are the driving medium when the percussion piston is pushed back and forth leans against the cylinder body and so with every stroke with the same thrust, which the percussion piston experiences, also acts backwards against the cylinder end wall. However, the severity of the shock is mitigated by the greater braking weight of the cylinder in relation to that of the percussion piston; the strength of the shock the ratio of both. to the opposite of the size of the weights.

Es ist schon früher der Versuch gemacht worden, diesen Rückstoß des Zylinders durch ein zwischen die Hand des Arbeiters und den Zylinder eingeschaltetes elastisches Medium abzufangen und dadurch unwirksam zu machen., und zwar sowohl durch Federn als auch durch Luftpuffer. Übersehen wurde dabei. aber, daß diese elastischen Medien auch einer genügend schweren Stütze bedürfen, um den Stoß abfangen zu können, ohne den Arbeiter zu belästigen.Attempts have been made earlier to reduce this recoil of the Cylinder by an inserted between the hand of the worker and the cylinder to intercept elastic medium and thereby render it ineffective., both by springs as well as by air buffers. Was overlooked. but that this elastic Media also require a sufficiently heavy support to be able to absorb the impact, without bothering the worker.

In der vorliegenden Erfindung ist nun das Hauptaugenmerk auf die richtige Verteilung der Gewichte gelegt. Es wird hier der Zylinder selber so leicht gehalten, als es ohne Gefährdung der Betriebssicherheit geschehen kann. Der hierdurch naturgemäß heftigere harte Rückstoß überträgt sich nunmehr zuerst auf die elastische Zwischenbremse und wird dort zu einem weichen Druck. Dieser Druck setzt sich dann auf die schwere Handhabe fort, die zugleich als Stütze für das elastische Zwischenmedium dient. Und zwar ist das beim Zylinder gesparte Gewicht der Handhabe zugeteilt, und um das Gewicht des ganzen Systems nicht größer als vorher werden zu lassen, sind in die Handhabe alle Konstruktionsteile .eingebaut, die nicht unmittelbar zum Zylinder gehören.In the present invention, the main focus is now on the correct one Distribution of weights placed. The cylinder itself is held so lightly here, than can be done without endangering operational safety. Naturally, as a result more violent hard recoil is now transferred first to the elastic intermediate brake and becomes a soft pressure there. This pressure then builds on the heavier Handle away, which also serves as a support for the elastic intermediate medium. In fact, the weight saved on the cylinder is allocated to the handle, and around that The weight of the whole system should not be greater than before I have built in all construction parts that are not directly to the cylinder belong.

Claims (1)

PATENTANSPRUCH: Maschineller Handhammer mit elastischer Rückstoßdämpfung, dadurch gekennzeichnet, da.ß sich die elastische Bremse auf eine schwere Handhabe stützt, die infolge ihrer Massenträgheit den Rest des Rückstoßes aufnimmt. PATENT CLAIM: Mechanical hand hammer with elastic recoil damping, characterized in that the elastic brake is based on a heavy handle which, due to its inertia, absorbs the rest of the recoil.
