Solid actuator e.g. piezoelectric multilayer actuator, drive apparatus for e.g. lathe, has basic structure of housing block provided in section perpendicular to longitudinal axis of shaft, where apparatus is formed as piezomotor

摘要

The apparatus has a drive body for shifting a shaft (4), where the body has a round drive opening from which the shaft is led out. The apparatus is formed as a piezomotor. An outer diameter of the shaft is smaller than an inner diameter of the opening. A symmetrical basic structure of a housing block (1), which carries a solid actuator unit and the body, is provided in a section, which is perpendicular to a longitudinal axis of the shaft.
