Rotation Drive Application Prospects

- May 27, 2017 -

Rotary drive in the precision movement, micro-operation, optical engineering, Rotary Actuators precision positioning and other precision engineering has broad application prospects.

(8) fixed to the fixed base plate (9), an output shaft (7) mounted on the inner ring of the precision bearing (8), the inner end of which is arranged on the output shaft (7) (1), 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 the second drive mechanism (5) (2), a first piezoelectric ceramic driver (4) and a second piezoelectric ceramic driver (6), the clamping mechanism (1), the first drive mechanism (3) and the second piezoelectric ceramic driver ) And the outer end of the second drive mechanism (5) are fixed to the drive housing (10), the center of the output shaft (7) being on the short axis of the clamping mechanism (1), the output shaft (7) (2), the first piezoelectric ceramic driver (4), Rotary Actuators and the second piezoelectric mechanism (4) are not on the short axis of the first drive mechanism (3) and the second drive mechanism (5) The ceramic driver (6) is capable of deforming the major axis of the clamping mechanism (1), the first drive mechanism (3) and the second drive mechanism (5), respectively, when the electrical drive (6) is energized, which causes the short axis length to be shortened, So that the clamping mechanism (1), the first (3) and the second drive mechanism (5) are disengaged from the output shaft 7, and in the clamped piezoelectric ceramic driver (2), the first piezoelectric ceramic driver (4) and the second piezoelectric ceramic driver 6), the clamp mechanism (1), the first drive mechanism (3) and the second drive mechanism (5) can be brought into contact with the output shaft (7), respectively, so that the output shaft (7) ) Exert a force.

The rotary drive is connected to the base by a sliding bearing, wherein the stator comprises a clamping mechanism and a drive mechanism, Rotary Actuators an integral and closed structure connected by a plurality of double thin-walled flexible hinges, and the piezoelectric ceramic is mounted therein. The utility model can greatly improve the driving precision of the ordinary drive, reduce the complexity of the structure and reduce the size, Rotary Actuators and has the advantages of low cost, less investment, quick effect and high efficiency.
