The apparatus permits the relative rotation of a component on a rotating spindle by means of a superimposition drive having two inputs and one output. At one input the spindle rotation is fed in, while at the other a desired rotation of the component, which in turn is connected to the output of the drive, is fed in. The rotational position and/or rotating force can be measured and controlled. Applied to adjusting movements on machine tool spindles, for example for powered chucks or radially adjustable rotating tools. |
