Abstract
A shaking unit for the generation of one-dimensional oscillating movements of a machine part mass is provided having a coupling part for mechanical coupling to the machine part mass, a counter-mass which is coupled resiliently to the coupler part and, via the latter, to the machine part mass, and a drive system which acts in a sprung manner between the coupler part and the counter-mass. The coupling part may surround the counter-mass as a frame. At least one of two pneumatic springs of the drive system, which are arranged on both sides of the counter-mass, is loaded with a minimum and/or with a maximum load pressure of the pneumatic springs depending on an oscillation state.

A shaking unit for the generation of one-dimensional oscillating movements of a machine part mass, comprising:
- a coupling part for mechanical coupling to said machine part mass;
- a counter mass which is coupled resiliently to said coupling part and to said machine part mass;
- and
- a drive system which acts in a sprung manner between said coupling part and said counter mass, said coupling part surrounding said counter mass as a frame.
A shaking unit for the generation of one-dimensional oscillating movements of a machine part mass, comprising:
- a coupling part for mechanical coupling to said machine part mass;
- a counter mass which is coupled resiliently to said coupling part and to said machine part mass;
- and
- a drive system which acts in a sprung manner between said coupling part and said counter mass, said drive system including two pneumatic springs which are arranged on both sides of said counter mass.
A method for pneumatic excitation of a shaking unit for the generation of one-dimensional oscillating movements of a machine part mass, comprising the steps of:
- providing a coupling part for mechanical coupling to said machine part mass;
- providing a counter mass which is coupled resiliently to said coupling part and to said machine part mass;
- and
- providing a drive system which acts in a sprung manner between said coupling part and said counter mass, said driving system including two pneumatic springs which are arranged on both sides of said counter mass, at least one of said two pneumatic springs of said drive system being inflated with one of a minimum and a maximum load pressure of said at least one pneumatic spring, depending on the state of said oscillating movement.
