Description

Method for limiting the shaft deformation of a rotor. Sdbadld @ a runner of high number of revolutions in his normal rotation!, eschwin-speed is to be relocated, a critical one must be used both when starting up and when stopping Speed can be overcome with effort. When dec, runner b, mve-: gendeMutar Do not tell him any very high acceleration motions at this moment considerable deformations are to be feared. This does not cut it to restrict that one surrounds @ di-e Weltlie with rigid rings; @because soon after there has been contact between the two legs, a wave grinds! bioaung -In the longitudinal direction, sheathing, which also M serves a continuous increase the speed cannot be eliminated. Fortunately, this situation occurs not in case of breath processes ides stopping; as soon as ii: n this: trap, the fronds comes into contact with the ring, it soon breaks under the influence of its elasticity go, de then! is able to overcome the effect of centrifugal force.

In addition, Erhnderün has yielded for idi, e Läufierwell @ en: Bearings assumed, idii @ e by means of soft or resilient bodies with the housing are connected; wodiumch, a pnzfferarti @ ge relationship have been created, which one easily gives in, but on the other hand slowly rises up Aries able, whereby, a great amount of work is required for erecting.

This sol @ un # 7 is only applicable to stare Corrugations that turn in spring-loaded bearings.

The invention applies to pliable waves,: @lie sich in rotating fixed bearings. It consists in the bending of the waves To oppose resistance. those with their rotation speed grow steadily, and so: are calculated that they are in; the moment of this transition for the critical speed: can be restricted to a desired value.

, These resistors are not only unnecessary as soon as the critical @esclvw: indulgence is exceeded, but then even harmful, because it is a useless waste of strength cause ng and i the mobility: of the shaft decrease; therefore s: i: n.d. der Invention geinäß devices are provided which do not stick with these disadvantages are.

One cannot... The. To be created resistances directly to the.. Let the shaft rotating at high speed have an effect, because it zu-Rückpralil, en would :, so that they are in contact with fixed points of a wave would come; .therefore, according to the invention, rings are arranged at the points of the rotor shaft on; to iden: z. B. two ends of the moving @ dc @ ien shaft are coupled. These rings are set up in such a way that they do not move along with the rotation of the Anabaptist wave but can follow all lateral shifts of the shaft.

-Nine the rotor shaft is rigid and supported by spring-loaded bearings this kind of ring becomes superfluous.

The: the subject of the invention is the device in its essential parts in A! bb. i illustrates and, consists of three pistons i, -which are slidable in three cylinders: 2. The Zv # li.nd # adjoin each other at angles of i2o °.

In the exemplary embodiment shown, it is assumed that d @ aß @ d'iie Calving with at their ends. balls 26 besieged the Hiegsaine wave q. under mediation a ball bearing arranged on it, 3 supports; -These pistons, n can iiin greater @ e @ r, er than the number drawn and with equal angular intervals ziieina.nder a, ngcoridniet will.

The cylinders 2 are filled with a viscous liquid and the pistons i @ n them .with i iRe% nig inserting them more easily. about the missing of the used Liquid through the contact surfaces between, the piston and the cylinder, the, wän.deil as possible to restrict.

The feed ring tubes for the cylinder fluid are like iin .Nhb. i shown, arranged in a radial fashion. The tubes 5 are on the floors the cylinder 2 connected and half a sufficiently large cross-section, tini none Losses when supplying the cylinder, supplying liquid Pipes 5 are connected to very icy pipes 6, which on the other hand, in a pipe wall: flow out. Rahrie 6 prevent charge losses for the cylinder liquid and '1i id.en Iden seat for shock absorption.

The pipes 6 are fed by a niiit Hah: ni 9 provided Tube 7, which is connected to a container 8, in which the liquid for loading, the cylinder is available in sufficient quantity to d! iie the heads of the Koliben still to be pressed against the ring for a speed that ready-. lx- (is slightly higher than the critical one, e.g.

is equal to this speed. Soha1: di Once this has been achieved, the Brenas effects are no longer harmful in order to have to be suppressed. A speed meter, the form of which changes with the different types of application, is used for this purpose. the connection between the three pipes, 6 and (learn to interrupt the container by closing the tap 9; the liquid then gradually escapes through the presence of leaks ti: nd ', idii, e through the channel, - In their piston, which is limited in their stroke, they can after a short time know how to carry out an advance movement that is more against the ring.

The Danes of the introduction to the speed of a machine is always very little, hence the amount of fluid which is during during this period of time -divide the K.oliben- and; The cylinder could escape, be very low. The need to put them under pressure id, u: rch. Somehow experienced Having stored up will therefore not pose any serious difficulty.
