| Zusammenfassung: | An apparatus for producing a holding or transmission frame (12, 20) for an electrostrictive actuator, in particular, a stacked piezoactuator (5) includes the following steps: a) a winding spindle (52), corresponding to the shape of the inner periphery of the frame (12, 20), is wound with several layers of a unidirectional prepreg for forming a laminate body; b) the laminate body is hardened; c) the hardened laminate body in the frame is cut by sections parallel to the direction of winding. An electrostrictive drive (100) includes an electrostrictive actuator (5) in which the length varies during actuation, and a transmission frame (12) that surrounds the actuator, is connected to the actuator for initiating the variation in length of the actuator and for amplifying the actuator, the transmission frame (12) being made of a prepreg that is wound in the laminate body and hardened. |
