Apparatus and method for compensating a weight of at least one vertically movable component of a coordinate measuring machine and coordinate measuring machine

摘要

A device according to the invention for compensating for a weight force (F) of at least one vertically movable component of a coordinate measuring machine (1) comprises a spring, a first end region of the spring being connected to a vertically fixed component of the coordinate measuring machine (1), a first traction means connected to a A first drum, on which the first traction means is wound up and unwound, a second drum, which is rotationally coupled to the first drum, and a second traction means, which is mounted on the second drum on the second drum. and unwindable and that is connected for receiving at least a part of the weight force (F) of the at least one vertically movable component, wherein the first traction means engages the first drum with a decreasing with increasing wound length of the first traction means lever arm and / or the second traction means on the second drum with a increasing wound length of the second traction means engages decreasing lever arm. The invention also relates to a method for compensating for a weight force (F) of at least one vertically movable component of a coordinate measuring machine (1) and a coordinate measuring machine (1).
