Abstract
The present invention discloses an electric operator. The electric operator comprises an ultrasonic motor, a harmonic gear drive mechanism, a signal conversion unit and a central processing unit. The ultrasonic motor is taken as output sources of torque and mechanical power, and outputted torque and mechanical power is outputted to drive the angular displacement of a valve after the torque and mechanical power are subjected to deceleration through the harmonic gear drive mechanism and torque amplification; and the signal conversion unit is configured to convert the angular position of the valve to electric signals and return back the electric signals to the central processing unit, and the central processing unit emits driving signals to drive the ultrasonic motor. The electric operator is characterized by combining small size of an ultrasonic motor, large output torque, an internal machinery self-locking function and small size and high precision of harmonic wave drive, and is especially suitable for application occasions with small size and high precision.
Description
Technical field
The present invention relates to a kind of electric operator.
Background technology
Electric operator is a kind of electronic product that machine driving, motor and control circuit are bound organically in one by program software, and in general, executor mainly realizes angular displacement and the displacement of the lines determined. The executor realizing angular displacement has many revolutions and part revolution, it is achieved displacement of the lines is Direct Travel. In the technical scheme of electric operator, Mechanical & Electrical Transmission scheme is the centre point of electric operator correlation technique, and it is good and bad that different drive motors and drive mechanism determine actuator performance in itself.
Under the limited industry in naval vessels, aerospace vehicle or other locus and commercial environment, some electric operator must is fulfilled for the requirement of high transmission efficiency, high transmission accuracy, low noise, therefore the electric operator of existing employing electromagnetic machine and rigid mechanical transmission is no longer appropriate for, it is necessary to a kind of new electric operator could meet day by day miniaturization, high-precision demand.
Summary of the invention
The technical problem to be solved in the present invention is how to provide a kind of high transmission accuracy and efficiency, reduces the electric operator of noise.
For solving above-mentioned technical problem, the invention provides a kind of electric operator, including: ultrasound electric machine, harmonic gear drive mechanism, signal conversion unit and CPU, described ultrasound electric machine is as the output source of moment of torsion and mechanical output, the moment of torsion of its output and mechanical output, after described harmonic gear drive mechanism slows down and moment of torsion amplifies, export the external world and drive valve to do angular displacement; Described harmonic gear drive mechanism includes wave producer, just takes turns and the flexbile gear be located on described wave producer, and described wave producer one end is connected with described ultrasonic motor, and the other end is engaged with described firm wheel by described flexbile gear, and described firm wheel is provided with output shaft; Described signal conversion unit returns described CPU for converting the angle position signal of valve to the signal of telecommunication, and described CPU sends driving signal and controls described ultrasound electric machine.
Preferably, also including: intermeshing fixing just wheel and worm screw, and described fixing just wheel engages with described flexbile gear, described worm screw is provided with Self-locking angle, make described ultrasonic motor when working described worm screw be automatically locked.
Preferably, described signal conversion unit is be provided with the panel of Hall chip and be provided with the rotating speed bar of Magnet, and described rotating speed bar one end is provided with gear, and engages with described firm wheel.
Having important advantages in that of this electric operator combines the feature that ultrasound electric machine volume is little, export big, the inherent mechanical self-latching function of moment of torsion and the gear-driven small volume high precision of harmonic wave, is especially suitable for small size, high-precision application scenario.
