Description
Technical field
The present invention relates to a kind of supersonic motor.
Background technology
Traditional wave mode supersonic motor of advancing is by relative to the vibration body of contact with move body and constituted.The vibration body is made up of the elastic vibration body that can become the piezoelectric of mechanical energy to electric energy and be fixed on the piezoelectrics.Mobile body is by moving body and adopt the mover of friction material to form.After piezoelectrics being added the power supply of appropriate frequency, lip-deep each particle of vibrating body is done elliptic motion, makes the vibrating body surface produce traveling wave, and its crest contacts with the moving body surface, rotates by the friction-driven rotor.But this motor is because passing through overall viewing range, so there is the defective along with the increase rotating speed minimizing of load.
Summary of the invention
The purpose of this invention is to provide a kind of traveling wave engagement type supersonic motor, this traveling wave engagement type supersonic motor has solved the defective along with the increase rotating speed minimizing of load.
The technical solution used in the present invention is: a kind of traveling wave engagement type supersonic motor, comprise base, motor cover, main shaft, stator, the stator piezoelectric ceramic, the stator friction plate, rotor, friction rotor sheet, the rotor piezoelectric ceramic, junction block, power line, butterfly spring, axle sleeve, the metal slip ring, insulating sleeve and dead ring, motor cover is installed on the base by base screw, main shaft is installed in the motor cover, the main shaft top is installed on the motor cover by bearing, and the below of main shaft is installed on the base by bearing, and the superstructure of main shaft is multidiameter, axle sleeve is installed respectively on this multidiameter from top to bottom, butterfly spring and insulating sleeve are set with metal slip ring and dead ring at insulating sleeve.The middle part of main shaft is equipped with rotor by rotor with screw, be stained with the rotor piezoelectric ceramic above the rotor, be stained with the friction rotor sheet below the rotor, stator is screwed on base by stator, be stained with the stator piezoelectric ceramic below the stator, be stained with the stator friction plate above the stator, stator friction plate and friction rotor sheet are in contact with one another.Junction block is fixed on the motor cover side by button-headed screw, and an end of power line links to each other with junction block, and the other end of power line links to each other with the metal slip ring, and the metal slip ring is connected with the rotor piezoelectric ceramic by lead.
When the traveling wave wavelength of stator and rotor surface, phase velocity, amplitude equate, because of traveling wave equidirectional rotation under the state of being meshing with each other of contact surface, so this moment, rotor was static.The frequency of rotor or stator is supplied with in fine setting in this state, and it is poor to produce phase velocity between two traveling waves, makes the rotor rotation.During less than maximum permissible torque, its rotating speed only depends on that two driving frequencies are poor to the new type ultrasonic motor that the phase velocity difference drives, and irrelevant with load at load torque.
The invention has the beneficial effects as follows: stator and rotor surface all produce traveling wave, and are intermeshing between the traveling wave, transmit moment of torsion by engagement.Can be under the Ultra-Low Speed state, stable rotation, stepless speed regulation, and can under open cycle system, control rotating speed exactly.
