The invention relates to an unbalance vibrator in which the flyweights of rolling on a track fixed to the housing Rolling bodies are formed.

Compared to the usual Unwuoht vibrator constructions which the flyweights sit firmly on the shaft of the runner, a construction of the aforementioned type has the advantage that the bearings of the vibrator runner are not affected by centrifugal forces are stressed «The centrifugal forces of those who are forced to fly work rather, directly on the housing. There is also no deflection of the rotor shaft as a result of the centrifugal forces » which can have a detrimental effect, especially when the vibrator is driven electrically. Well-known Unwuoht vibrators with Hollow bodies that roll off directly on the housing as flyweights have the disadvantage that only the shaking force difficult to adjust. Bsi Unwuobt-RUfetlern, with whom the flyweight® is wedged with the rotor shaft is known to be a classification of the resulting Unwuoht and thus the shaking force dadursh achieve that the Flyweights consist of two mutually rotatable parts.

The present invention is therefore the object of an unbalanced vibrator of the type mentioned form so that the size of the resulting unbalance can be set according to the respective characteristic ErforderniBnen «a» ortQ «« ^009831/0229

Pie invention consists in the fact that the runner of the vibrator in the plane of the track around radial wings in has regular intervals »between which rolling elements ο can be inserted in different numbers and / or arrangements to achieve different resulting centrifugal forces

Advantageously, the arrangement is made so that on Runner of the Hüttlera at both ends such radial wings are provided and are also rotatably mounted in the same plane in a regular arrangement rollers over which runner is stored in the raceways. In this way, the raceways on the housing are used at the same time Storage of the runner. Separate layers for the runner can be omitted.

An embodiment of the invention is shown in the figures and described below:

Fig. 1 shows a longitudinal section through a vibrator according to the invention.

Fig. 2 shows a section length of the line AB τοη Fig.t.

Flg. 3 also shows the section AB from FIG a different arrangement and number of rolling elements serving as flyweights.

A cylindrical vibrator housing 10 let at the ends by cover points (i1, 12 closed * In the housing sits in the putty « the stator 13 of an electric drive motor, whose Runner is denoted by 14.

Runner 14 carries a disk 15 and at each of its ends

16 with a cylindrical ring 17 or ... 18. Of the rings

17 and 18, respectively, radial wings 19 extend outwards _9, as can be seen most clearly in Pig. 2 and 3. In addition, rollers 20 are rotatably mounted on the disc 15 or 16, offset by 90 ° in relation to one another. The rollers 20 rest on the running tracks 21 formed on the inside of the vibrator housing, so that the runner of the vibrator is mounted on the rollers 20 in the running tracks 21 of the housing and a separate bearing for the runner 14 can be omitted.

Between the various radial wings 19, rolling elements, for example balls or small cylinders 23, can be inserted which act as centrifugal weights and which are carried along by the wings 19 as the rotor 14 revolves and which, under the influence of centrifugal force, rest on the outside of the races 2% of the housing 10. An asymmetrical arrangement of the centrifugal weights 23 generates a resulting centrifugal force which takes effect directly on the housing 10. The size of this centrifugal force can be varied by the number and / or the arrangement of the centrifugal weights 23.

Fig. 2 shows, for example, an arrangement in which a maximum centrifugal force is generated since the centrifugal weights 23 are all arranged on one half of the runner urafang.

In the arrangement according to Fig. 3, in addition to. the in Fig.2 shown flyweights 23 two further flyweights 23 °, 23 ″ are provided, which in relation to the Aobae of the rotor 14 centralsyraetrically to the mean flyweights 23 in the other half of the rotor.

This compensates for their flying craft, so that a significantly reduced number of returns is effective instead The two lower middle flyweights 23 could of course have been removed in the arrangement of FIG.

The described construction makes it possible to The shaking force of the vibrator can vary within relatively wide limits. Instead of the number and location of the flyweights au change, flyweights of different specific gravity can of course also be used.
