Abstract
A device for balancing eccentricity of a spindle drive () to avoid blocking of the spindle drive during lifting movement of a platform (), in which the platform is mounted on several axiparallel spindles (G; G; G; G) by bearing devices (L; L; L; L) arranged on it and can be lifted together with the bearing devices axially along the spindle. The spindle drive () has at least three axiparallel, rotatable threaded spindles (G; G; G; G) with bearing device (L; L; L; L) in a polygonal arrangement; low-friction bearing devices (L; L; L; L) with radial bearing clearance (F; F) are arranged to balance the radial eccentricity of the rotating threaded spindles so that a relative radial movement of the rotating spindles to platform () is possible with limited force expenditure.
