摘要: The invention relates to an ultrasonic actuator, preferably for use in an ultrasonic motor, in the form of a piezoelectric plate with a length L, height H and thickness t, wherein the piezoelectric plate has a lateral plane of symmetry Sq, a longitudinal plane of symmetry Sl and at least two main surfaces, and the piezoelectric plate comprises at least two generators symmetrically disposed with respect to plane of symmetry Sq for generating ultrasonic standing waves. According to the invention, the piezoelectric plate has a shape that includes at least eight lateral surfaces, wherein at least two of the lateral surfaces are working surfaces for contacting of elements to be driven, and at least two of the lateral surfaces are holding surfaces for holding the piezoelectric plate, and the remaining lateral surfaces are free surfaces, wherein at least four free surfaces are arranged at an identical angle α with respect to the longitudinal plane of symmetry Sl and/or at an identical angle φ with respect to the lateral plane of symmetry Sq.

摘要: An inertial drive is disclosed, comprising a length-changeable actuator element (1), a frame element (4) with a support section and with a deformation section, against the contact surfaces of which the actuator element bears, wherein the deformation section has an articulation section (13), a flat spring element (5) which is arranged on the deformation section and has a friction section (3) at the free end thereof, and a friction body (2), which can be driven, in mechanical contact with the friction section. A change in length (S) of the actuating element causes a rotatory movement (D) of the deformation section about the articulation section, which movement is transmitted via the spring element to the friction section for driving the friction body which can be driven.

摘要: The invention relates to a piezoelectric rotary drive for a shaft, comprising a piezoelectric actuator (or piezo actuator or actuator) and a clutch section, which can be coupled to the shaft in a force-fitting manner for achieving a stick-slip drive. In order to provide a piezoelectric rotary drive for a shaft which can transmit relatively high contact forces between the frame and the shaft, in particular in the stick phase, the invention provides the piezoelectric rotary drive for a shaft according to claim 1, comprising at least one piezoelectric actuator and an adjustable and/or deformable frame with at least one clutch section, which can be coupled to the shaft in a force-fitting manner for achieving a stick-slip drive, wherein the frame converts a piezoelectric deformation of the actuator mechanically such that the clutch section rotates about the axis of the shaft over at least part of the circumference of the shaft.
