| 摘要 |
<p>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.</p> |
