Description

Vorrichtung zum Massenausgleich wellenelastischer Körper Es sind Vorrichtungen zum Massenausgleich beliebiger Umlaufkörper bekannt, bei denen in einer oder mehreren parallel zur Drehachse angeordneten Bohrungen oder in der axialen Bohrung selbst in bestimmten, zur Drehachse senkrechten Ausgleichsebenen Ausgleichstücke angeordnet werden. Dieser Massenausgleich genügt, solange die auszuwuchtenden Umlaufkörper praktisch als starr angesehen werden können.Device for balancing the mass of wave-elastic bodies There are devices known for mass balancing of any recirculating body, in which in one or more bores arranged parallel to the axis of rotation or in the axial bore itself Compensation pieces are arranged in certain compensation planes perpendicular to the axis of rotation will. This mass balancing is sufficient as long as the recirculating body to be balanced can practically be regarded as rigid.

Die Schwierigkeit aber, einen raschumlaufenden .wellenelastischen Körper auszuwuchten, besteht darin, daß die auf die Lager wirkenden störenden Zentrifugalkräfte nicht nur von den eigentlichen Unbalancen herrühre., sondern auch von den Durchbiegungen des elastischen Körpers, die durch diese Zentrifugalkräfte hervorgerufen werden.The difficulty, however, is to find a rapidly circulating, wave-elastic Balancing bodies consists in the fact that the disturbing centrifugal forces acting on the bearings not only from the actual imbalances, but also from the deflections of the elastic body caused by these centrifugal forces.

Ein ideales Auswuchten kann offenbar nur so geschehen, daß man die Unbalancekräfte in denselben Radialebenen, in denen sie auftreten, vernichtet, nicht erst von den sogenannten Tarierebenen aus.An ideal balancing can obviously only take place in such a way that the Imbalance forces in the same radial planes in which they occur are destroyed, not only from the so-called tariff levels.

Bei einem elastischen zylindrischen Körper ist es aber schwierig und häufig unzulässig, an der Oberfläche diametral zu den Stellen, an welchen die Massenfehler sitzen, Massen abzunehmen oder solche anzubringen, um das Auswuchten zu erreichen.In the case of an elastic cylindrical body, however, it is difficult and often inadmissible, on the surface diametrically to the points at which the mass errors sit, remove masses or attach them to achieve balancing.

Es soll daher ein Weg angegeben werden, wie man diesem Übelstand abhelfen kann. Dies geschieht gemäß der Erfindung dadurch, daß die Ausgleichstücke, die etwa auf einem Dorn befestigt sind, parallel zur Längsrichtung -der Prüfkörperachse verstellbar sind. Erteilt man nach Abb. i und 2 dem auszuwuchtenden Körper i, .der in den Lagern 2 umläuft, eine Anzahl Bohrungen 3 parallel zu seiner Achse, wobei die Bohrungen etwa in gleichem Abstand symmetrisch um diese angeordnet sind, so kann man durch Einführung von da hineinpassenden Ausgleichstücken, die vollzylindrisch, 4, teilzylindrisch, 5, insbesondere halbzylindrisch, 6, sein 'können, erreichen, indem man diese probeweise verschiebt und verdreht, daß der Rotor, der zur Kontrolle zwischendurch auf Tourengebracht wird, nahezu schwingungsfrei läuft, und zwar für alle Tourenlagen.A way should therefore be given how to remedy this problem can. This is done according to the invention in that the compensation pieces, about are mounted on a mandrel, adjustable parallel to the longitudinal direction -the test body axis are. If one assigns to the body to be balanced i, .der in the bearings according to Fig. I and 2 2 revolves, a number of holes 3 parallel to its axis, the holes are arranged about the same distance symmetrically around them, so you can go through Introduction of compensating pieces that fit into it, which are fully cylindrical, 4, partially cylindrical, 5, in particular semi-cylindrical, 6, can be achieved by testing them shifts and twists that the rotor revved up for control in between runs almost vibration-free, for all touring situations.

In vielen Fällen wird es genügen, nach Abb. 3 und 4 eine einzige Bohrung 7 zu benutzen, deren Achse mit der Rotorachse zusammenfällt. In diesem Falle dürfte es sich hauptsächlich empfehlen, die einzuführenden Ausgleichstücke 8 halbzylindrisch herzustellen gemäß der Abb. 5 und 6.In many cases it will be sufficient to drill a single hole as shown in Figs. 3 and 4 7, the axis of which coincides with the rotor axis. In this case it should it is mainly recommended that the compensating pieces 8 to be introduced be semi-cylindrical manufactured according to Figs. 5 and 6.

Damit die Ausgleichstücke an ihrer endgültigen Stelle verbleiben, ist es nötig, sie z. B. vorher über einen Dorn g der Abb. 3 und 4 zu schrauben, der am Ende der Bohrung festgehalten wird, oder sie nach irgendeinem anderen der vielen technischen Möglichkeiten hinsichtlich der Bohrung zu fixieren.So that the compensation pieces remain in their final position, is it necessary to B. to screw beforehand over a mandrel g of Figs. 3 and 4, which is held at the end of the hole, or it after any other of the to fix many technical possibilities with regard to the drilling.
