| titleOfInvention | Ultrasonic actuator |
| abstract | The invention relates to an ultrasonic actuator ( 2 ) with a polarization axis P, said actuator being made of a piezoelectric ceramic. The ultrasonic actuator ( 2 ) has a temperature expansion coefficient which is parallel to the polarization axis P and which differs from a temperature expansion coefficient that is perpendicular to the polarization axis P, and at least one friction element ( 8 ) is arranged on the ultrasonic actuator. The friction element ( 8 ) consists of an anisotropic monocrystal with temperature expansion coefficients which are different along the three crystal axes a, b, and c. The temperature expansion coefficient along a first of the three crystal axes is the lowest, and the temperature expansion coefficient along a second of the three crystal axes is the greatest. The friction element ( 8 ) is aligned relative to the ultrasonic actuator ( 2 ) such that the first crystal axis is parallel to the polarization axis P of the ultrasonic actuator ( 2 ), and the second crystal axis is perpendicular to the polarization axis P of the ultrasonic actuator ( 2 ). The invention additionally relates to an ultrasonic motor with an ultrasonic actuator of the aforementioned type. |
