Abstract
A device for linearly moving a useful mass is described. Typically, when a large useful mass is moved, relatively large forces are transferred by a spindle or a toothed rack to the corresponding machine or machine frame. These forces can be compensated by moving a compensating mass in the opposite direction of the useful mass.
Claims7
A device for linearly moving a useful mass, comprising:
- at least one spindle;
- at least one drive rotating the at least one spindle;
- a first spindle nut coupled with the useful mass and moving the useful mass in a first direction;
- and
- a second spindle nut coupled with a compensating mass and moving the compensating mass synchronously with the useful mass in a second direction opposite to the first direction, so that a momentum of the useful mass is compensated by a momentum of the compensating mass.

A device for linearly moving a useful mass, comprising:
- at least one toothed rack;
- at least one pinion engaging with the toothed rack;
- at least one drive rotatably driving the at least one pinion;
- a first of the at least one pinion coupled with the useful mass;
- and
- a second of the at least one pinion coupled with a compensating mass and moving the compensating mass synchronously with the useful mass in a second direction opposite to the first direction, so that a momentum of the useful mass is compensated by a momentum of the compensating mass.
