Characteristics Of Porcelain Rotary Actuator
- Aug 14, 2017 -

The porcelain rotary actuator comprises a precision bearing fixed on the fixed plate, an output shaft mounted on the inner ring of the precision bearing, a clamping mechanism, a first drive mechanism and a second drive mechanism arranged in the inner end of the output shaft cycle. A piezoelectric ceramic actuator, a first piezoelectric ceramic actuator, and a second piezoelectric ceramic actuator are respectively mounted on the clamping mechanism, the first drive mechanism and the long shaft of the second driving mechanism, Rotary Actuators and the center of the output shaft is on the short axis of the clamping mechanism, The center of the output axis is not on the short axis of the first drive mechanism and the second drive mechanism; The invention also discloses a driving method of the drive, the linear displacement of the output of the porcelain rotary drive is shifted to the angular displacement, Rotary Actuators and the rotation of the driving device is realized through the coordinated stepping of a plurality of piezoelectric ceramic actuators, with the characteristics of compact structure, small size and light weight.

The rotary drive of porcelain is characterized in that it includes a precision bearing (8) fixed on a fixed floor (9), an output shaft (7) mounted in the inner ring of a precision bearing (8), a clamping mechanism (7) arranged on the inner end of the output shaft (1) cycle, Rotary Actuators the first drive mechanism (3) and the second drive mechanism (5) are respectively installed in the clamping mechanism (1), the first drive mechanism (3) and piezoelectric ceramic actuators (2) and first piezoelectric ceramic actuators (4) for clamping on long shafts in second drive mechanism (5) and a second piezoelectric ceramic actuator (6), the outer end of the clamping mechanism (1), the first driving mechanism (3) and the second driving mechanism (5) is fixed on the driving housing (10), and the center of the output shaft (7) is on the short axis of the clamping mechanism (1), the center of the output shaft (7) Rotary Actuators is not on the short axis of the first drive mechanism (3) and the second driving mechanism (5); Piezoelectric ceramic Actuator (2), first piezoelectric ceramic driver (4) and second piezoelectric ceramic actuator (6) The clamping mechanism (1) and the long shaft of the first driving mechanism (3) and the second driving mechanism (5) is deformed, and the deformation will shorten the length of the short shaft, thereby making the clamping mechanism (1), the first drive mechanism (3) and the second drive mechanism (5) out of contact with the output shaft 7, and the clamping mechanism (1) and the first drive mechanism are respectively used in the clamping device (2), the first piezoelectric ceramic actuator (4) Rotary Actuators and the second piezoelectric ceramic drive (6). 3) and the second drive mechanism (5) Restore the original length, contact the output shaft (7) to exert force on the output shaft (7).
