"Device, especially for a vibrating device, to indern the phase position of two unbalanced masses"

Me invention relates to a device, in particular for a Rüttelgerät, for Indians the phase position of two angeordenter on sep harvest waves and to be driven in the counterclockwise sense Unwuchiten which are interconnected by a form-locking gear which coaxially to one of the U and with _n heave arranged this' unbalance Has non-rotatably connected unbalance gear which meshes with a rocker gear arranged on a rocker which can be pivoted coaxially to this unbalance.

In a known self-moving vibratory device for soil compaction or for similar purposes. also provided a pivotable rocker arm coaxially to the other unbalance Swing gear with the corresponding unbalance gear and meshes with the other rocker gear so that the two imbalances are about four. Gears in operative connection with one another stand, with the. Unbalance gears do not mesh with each other,

To change the phase position of the unbalances, a link connecting the two rockers is provided. With the well-known Vibrating device is the phase position of the two unbalances only in

a "limited case: oh to change (Auslegeschrift 1 090 589).

At a well-known self-propelled compacting china two unbalances are arranged on the same shaft so that they can be mutually rotated and with one another via a differential gear connected, the housing of the differential by means of a snow shoot is to be driven. Any change in the phase position of the imbalances can be achieved with this. The known measure is only to be used for imbalances, which are arranged coaxially to one another (German patent specification 822 979.).

The present invention is based on the object of achieving any change in phase position with unbalances arranged on two separate shafts. This A _u fgabe is achieved according to the invention in that a coaxially arranged to the rotation with the unbalance gear connected unbalance auxiliary gear from the swing gear to be driven at least indirectly in the counterclockwise sense about this imbalance and that the auxiliary gear via a f ormschlüssjgen gear with the unbalance on the other Wave is in operative connection. The rocker is to pivot in a full circle, whereby such a design of the device can be selected that the. Swing between the shafts carrying the unbalances.

A further development of the invention consists in that a reversing gear is mounted in the rocker arm, which at least indirectly meshes with the rocker gear and the auxiliary gear. Such a design is used when there is sufficient space in the axial direction for the device. W _e nn a gear to be saved, three wheels can mesh with each other · The training simply vieist designed parts

and is therefore cheap to manufacture.

Another development of the invention consists in the fact that the auxiliary gear has internal teeth, and that that Swing gear and the unbalance gear inside the auxiliary gear are arranged. Using an intermediate gear with external and internal toothing can be done without great effort achieve a space-saving device.

The Pig. 1 and 2 of the drawing show two devices intended for a vibrating device for changing the phase position of two unbalances in a perspective, schematic representation, wherein only essential parts of the invention are shown.

The first embodiment according to Pig. ^{1 has two unbalances 2 and 2 f} arranged in the same plane on separate shafts 1 and 1 ·. While the imbalance 2 is loosely mounted on the bowl 1, the imbalance 2 'is connected to the shaft 1 in a rotationally fixed manner. The unbalance 2 is firmly connected to an unbalance gear 3 which is also mounted on the Inelle 1. A rocker 4 is pivotably mounted on the shaft 1 and has a handle 5 which is used to pivot the rocker 4 in both directions and which can be fixed in its respective position.

A swing gear 6 meshing with the unbalance gear g is rotatably mounted on a mounted in the rocker 4 shaft 7 '. One arranged at a distance from the swing gear 6 and with the MLIe 7 also non-rotatably connected swing gear 6 "" meshes with a 'reverse gear 8' which is on a in the rocker 4 and arranged parallel to the shaft 7 shaft 9 rotatably sits. A also rotatably with The reverse gear 8 'connected to the shaft 9 meshes with an auxiliary gear 10 which is rotatably supported on the shaft 1. At the auxiliary

gear 10 is a toothed belt or sprocket 11 is attached, which is via a toothed belt 12 or a chain with a aufder Shaft 1 'non-rotatably arranged toothed belt pulley 11 · or Sprocket is positively connected.

It is possible to use either the auxiliary gear 10 and the toothed belt or sprocket 11 on the one hand or the unbalance 2 and the unbalance gear 3 on the other hand rotatably with the shaft .1 connect to. When the reverse gear 8 with the swing gear 6 meshes, the rocker gear 6 'can be omitted. An unbalance pair, not shown, can be due to the unbalances 2, 2 'facing away from the ends of the shafts 1 or 1' are arranged. Of the Drive is via the shaft. 1 or 1 'to be introduced, whereby the wheels and imbalances in the direction of the. Rotate the arrows shown.

Will with otherwise; When the device is stationary, the handle 5 is pivoted in the direction of arrow A, so the rocker 4 becomes obetj. pivoted and the reversing gear 8 'rolls in the sense of the' drawn arrow on the stationary auxiliary gear 10 from. The reversing gear 8 transmits the rotary motion to the rocker gears 6 and 6 ', which in turn rotate the reversing gear 3 and the unbalance 2 in the direction of the arrows shown. Since the auxiliary gear wheel 10 and thus also the toothed belt or chain wheels 11 and 11 'and the associated unbalance 2 stand still, the rotational position of the unbalance 2 has been changed compared to the rotational position of the Wuscht 2'. The rotational position of the two unbalances can be changed by any angle, whereby it is only necessary to design the handle 5 in such a way that it does not rest on the shaft 1 '. Since the rocker can also be pivoted while shafts 1 and 1 'are running, the mutual rotational position of the two unbalances 2 and 2' can also be changed during the rotation of the unbalance.

In the second embodiment according to Pig. 2 wear the first Embodiment corresponding parts have the same reference numerals as in this ausungsbeispie1 and one more comma,

• if they are designed differently. An unbalance 2 "corresponding to the unbalance 2 of the first exemplary embodiment is here non-rotatably connected to a shaft 1" on which an unbalance gear 3 'is attached non-rotatably. A rocker arm 4 'is pivotably mounted on the shaft 1 ″, the handle 5 ′ of which can be pivoted in both directions and fixed in its respective pivot position. which meshes with the internal teeth of an auxiliary gear 10 ¹ . This also has an external toothing which meshes with an intermediate gear 12 *, which in turn meshes with a gear 11 "firmly attached to the shaft 1 '. Instead of the shaft 7', a swing gear can also be used

• 6 "bearing pin can be attached to the rocker 4 'or the rocker gear 6" can rotate on the then rotatable Wave 7 'sit. .

When the handle 5 'is pivoted in the direction of the arrow B. With the auxiliary gear 10' stationary, the wheels 6 "and 3 ', as well as the Unbalance. 2", are rotated in the direction of the arrows, so that with the appropriate design of the handle 5' the rotational positions of the two unbalances 2 "and 2 'can be changed to each other in a full circle. The drive of the unbalances can be initiated via the wheel 12' or one of the shafts 1" or 1 '. In current apparatus in the same way, a change in the phase position of the two unbalanced masses is' reach 2 "\ and 2. FIG.
