Description
Technical field
The utility model patent relates to a kind of low frequency piezo-electric motor, particularly a kind of impact type low frequency piezo-electric motor.
Background technology
At present, the phenomenon that vibration can form driving force by the conversion of suitable structure by people's understanding successful Application for many years, the operating frequency of ultrasonic motor more than 20kHz, the driving to rotor with the absolute oval coupled motions realization that forms conventionally.Thereby in theory as long as vibration is synthesized to oval coupled motions (or relatively oval coupled motions) by suitable structure, low-frequency vibration can form driving force equally, also just can as ultrasonic vibration, be used for constructing motor, but, existing low frequency motor is because structural design is unreasonable, in use vibration efficiency low for ubiquity, the problem of elevating movement poor effect.
Summary of the invention
The purpose of this utility model be for solve existing low frequency motor in use ubiquity vibration efficiency low, the problem of elevating movement poor effect and a kind of impact type low frequency piezo-electric motor of providing.
Impact type low frequency piezo-electric motor described in the utility model is comprised of ladder rotating shaft, rotor, stator, piezoelectric vibrator, Z-type sheet and base, its rotor and stator sleeve are located in ladder rotating shaft, rotor is located at stator top, between rotor and ladder rotating shaft, by bearing, be connected, stator and ladder rotating shaft interference fit, the lower end that is fixed on stator that piezoelectric vibrator tilts, the upper end of Z-type sheet is fixed on stator, and the lower end of Z-type sheet is fixed on base.
Ladder rotating shaft upper end is provided with helicitic texture near the position of rotor, and screw thread position is bolted with the nut matching, and nut screws on screw thread, can increase the contact force between rolling bearing and rotor, realizes frictional force and regulates.
Piezoelectric vibrator is comprised of piezoelectric patches, beryllium-bronze sheet and mass, and wherein piezoelectric patches sticks on beryllium-bronze sheet, and mass is connected in beryllium-bronze sheet outer end, and piezoelectric vibrator is provided with several.
Z-type sheet is provided with several.
Operation principle of the present utility model is as described below:
Piezoelectric patches after the alternating current of input certain frequency on piezoelectric vibrator will be done cyclic bending motion, drives the mass of beryllium-bronze sheet tail end to swing, because the inertia of mass is large, stator will be driven to rotate.Restriction due to Z-type sheet, stator will be done elevating movement in rotation, at ascent stage, owing to compressing with rotor, stator rotor driven can be rotated in the forward, in the decline stage, because stator is separated with rotor, stator idle running, makes rotor produce a micro-displacement, thereby complete the motion of one-period, so repeatedly drive rotor to rotate.
The beneficial effects of the utility model:
Rational in infrastructure, simple and practical, stator elevating movement effect improves, and motor vibrations efficiency improves.
