Description
Technical field
The present invention relates to a kind of supersonic motor, especially relate to one and shake chip standing wave type ultrasonic motor more.
Background technology
Supersonic motor is a kind of motor with brand-new driving principle, compared with tradition electromagnetic machine, ultrasonic
Ripple motor does not use coil, uses the coupling that rubs between piezoelectric ceramics inverse piezoelectric effect and rotor to complete electricity
Machine exports the conversion of energy from electric energy to torque.Supersonic motor has relative to electromagnetic machine that response is fast, low speed
Big torque, nothing input self-locking, without features such as electromagnetic interference.Current standing-wave ultrasonic ripple motor is inner-rotor-type
Shake slice structure, inner rotor core complex process, and part processing precision can not ensure, no in batch production
Enough power can be produced, can not apply.
Summary of the invention
It is an object of the invention to provide one to shake chip standing wave type ultrasonic motor more, use circle distribution
Vibrating reed type structure, outer rotor designs, motor and control integrated design, and use sensor, simplify
System structure.
The required problem solved of the present invention realizes by the following technical solutions: the present invention includes rotor
Parts, stator component, control circuit board, fixing fitting.Rotor part includes flange, rotor ring, axle,
Joined together by flange screw between axle and rotor ring.Stator component by piezoelectric ceramics, excitation ring, shake
Sheet forms, and fixes with glue between piezoelectric ceramics and excitation ring, shakes between sheet and excitation ring with being welded to connect,
And angled with axle, stator component is enclosed within support, is connected in control by column, pressing plate, latch
Becoming fixed component on the substrate of circuit processed, the sheet that shakes is elastomer and precompression supplier.
The rotor ring internal diameter ratio sheet external diameter that shakes is little, and the sheet that shakes uses elasticized thin sheet material to make, with rotor inner surface line
Contact, makes the bending tablet formation precompression that shakes.And at an angle with axis, form oval particle after exciting,
Drive rotor is to the direction motion that the sheet that shakes tilts.
Motor outside dimension φ 20-φ 35, highly 10-15mm, rotating speed 6-100r/min, torque 0.2-0.4Nm,
The local of sheet contact rotor although stator shakes, but because being that multi-disc contacts simultaneously, the sheet external diameter that shakes is interior more than rotor
Footpath, can produce the precompression applied after assembling, frictional dissipation does not increases, and noise does not increases, and the stator sheet that shakes does not has
There is the conventional radially fixed mode that uses, but the transmission of vibrational energy is lost little by axial manner, thus real
Show when same volume, the feature of the big torque of the slow-speed of revolution.
Relatively with general standing wave motor, the physical dimension of the present invention is short and small flat, and can be easily by electricity
Machine is fixed and on circuit board, and can be connected with other load by circuit board, does not affect the maneuverability of motor
Energy and precision.
Accompanying drawing explanation
The present invention is described further below in conjunction with the accompanying drawings:
Fig. 1 show the chip standing wave type ultrasonic motor structural representation that shakes more
Fig. 2 show the chip standing wave type ultrasonic motor rotor part schematic diagram that shakes more
Fig. 3 show the chip standing wave type ultrasonic motor stator component schematic diagram that shakes more
Detailed description of the invention
As shown in Figure 1: the present invention chip standing wave type ultrasonic motor that shakes includes rotor part 10, stator department more
Part 20, control circuit board 30, fixing fitting 40.As shown in Figure 2: rotor part 10 include flange 11,
Rotor ring 12, axle 13, joined together with screw by flange 11 between axle 13 and rotor ring 12.Such as Fig. 3
Shown in: stator component 20 is made up of piezoelectric ceramics 21, excitation ring 22, the sheet 23 that shakes, piezoelectric ceramics 21 with
Fix with glue between excitation ring 22, shake between sheet 23 and excitation ring 22 with being welded to connect, and and axis
Angled.As shown in Figure 1: stator component 20 is enclosed within support 41, by column 44, pressing plate 42,
Latch 43 is connected on the substrate controlling circuit becomes fixed component 40, and the sheet 23 that shakes is elastomer and precompressed
Power supplier.Rotor ring 12 internal diameter ratio sheet 23 external diameter that shakes is little.Bearing-free on axle, is carried out at the endoporus supported
Sliding friction, the upper plane that Flange Plane laminating supports, rotor is being supported by the circlip for shaft on axle
Another side axial restraint.
The sheet 23 that shakes uses elasticized thin sheet material to make, and forms precompression at rotor surface, and becomes one jiao with axis
Degree, forms oval particle after exciting, drive rotor is to the direction motion that the sheet that shakes tilts.
Circuit has installed additional photoelectric sensor 31, by detection rotor outer circle it is known that the angle that turns over of rotor,
Thus realize precisely operating.
