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.
Claims3
A device for linearly moving a useful mass, comprising:
- at least one first toothed rack;
- at least one first pinion engaging with the toothed rack and coupled to the useful mass;
- at least one first drive rotatably driving the at least one pinion for moving the useful mass along the toothed rack;
- and
- a compensating mass movable 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.
