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 having a pair of sides 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, and said counter mass is arranged therein so as to oscillate back and forth, wherein said drive system includes a pair of gas springs arranged on both sides of said counter mass so that said counter mass is pneumatically excited and a pneumatic excitation acts directly on said gas springs.
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, and said coupling part at least partially houses said counter mass such that said pneumatic springs are respectively arranged in between and contact the sides of said counter mass and said coupling part, wherein said drive system is pneumatically actuated to excitation, and said pneumatically actuated excitation acting directly on said two pneumatic springs.
