Positioning drive for precision component has operating element provided by transducer converting electrical and/or thermal energy into volumetric or shape variation

摘要

The positioning drive has a seating (4) for movable support of the precision component (3) and an operating element (5) for movement of the precision component, in the form of a transducer converting supplied electrical and/or thermal energy into a volumetric or shape variation. A wedge (7) is used as a setting device (8) for adjusting the distance between the operating element and the precision component.
