Abstract
A method for producing a structural unit with a prestressed piezoelectric actuator includes the steps of inserting a front end of the actuator into a hollow body, form-lockingly or force-lockingly connecting the inserted front end of the actuator to the hollow body, pressing the actuator into the hollow body with a defined force establishing a prestress of the actuator, and force-lockingly or form-lockingly connecting the actuator to the hollow body in the vicinity of a rear end of the actuator, for fixing the prestress of the actuator.
Claims3
A method for producing a piezoelectric structural unit, which comprises:
- a) inserting a front end of a piezoelectric actuator into a hollow body having a longitudinal direction;
- b) force-lockingly or form-lockingly connecting the inserted front end of the actuator to the hollow body;
- c) pressing the actuator into the hollow body with a defined force in the longitudinal direction for prestressing and establishing a desired prestress of the actuator in the longitudinal direction;
- and then
- d) force-lockingly or form-lockingly connecting the actuator to the hollow body in the vicinity of a rear end of the actuator, for fixing the desired prestress of the actuator.
