Abstract
A device for generating directed vibrations has two centrifugal weights which are independently driven at the same speed of rotation but in opposite directions. The centrifugal weights are supported on a largely stiff carrier secured by a holder to a bracket. The holder allows the carrier to move relative to the bracket. When the centrifugal weights start moving, they become synchronized within a short period of time and generate vibrations which can be used in the desired manner via the bracket.
Claims21
A device for producing directional vibrations, comprising:
- at least two centrifugal weights with essentially the same m x r which can be driven in rotation in opposite directions at essentially the same speed about mutually parallel axes of rotation;
- a largely rigid carrier, on which the centrifugal weights, are rotatably mounted;
- and
- a bracket on which the carrier can be mounted in such a way by means of a holder that the carrier can be moved relative to the bracket, the holder having at least one spring element for transmitting the movement of the carrier in the direction of the directional vibration and in a direction perpendicular to the directional vibration and perpendicular to the axes of rotation of the centrifugal weights, wherein
- the centrifugal weights can be driven independently of one another and
- the stiffness of the spring element is matched to the stiffness of the carrier.

A device to produce directional vibrations, comprising at least two centrifugal weights which have essentially the same m x r and which are configured to be rotated with at least essentially the same RPM in opposite directions about parallel axes;
- at least two independently operated drive units, each of which is configured to drive a dedicated one of the centrifugal weights such that the centrifugal weights are driven independently of one another;
- a largely rigid carrier to which the at least two centrifugal weights are rotatably mounted;
- and
- a bracket to which the vibrations are imparted;
- a holder which supports the carriage on the bracket so as to permit movement of the carriage relative to the bracket, the holder including at least one spring element configured to transfer the motion of the carrier in the direction of the directed vibration and in a direction perpendicular to the directed vibration and perpendicular to the rotating axes of the centrifugal weights, wherein a stiffness of the spring element substantially equals a stiffness of the carrier.
