The motor stator consists of stator base body and piezoelectric ceramic adhered together. The motor rotor consists of rotor base body, one pair of shaft sleeve and shaft. The motor seat consists of cover plate, pedestal, sleeve, one pair of washers, one pair of bearings, screw, nut, etc. When some AC voltage in ultrasonic frequency range is applied, the stator generates ultrasonic vibration, the rotor is rotated via adhesive force, and the power is output via the shaft. The motor has the advantages of high rotation speed, long service life, simple structure, low cost, etc.
Description
Technical field:
Cylinder non-contact ultrasound electric machine of the present invention belongs to the ultrasound electric machine in the small and special electric machine field.
Background technology:
Ultrasound electric machine is to utilize the inverse piezoelectric effect of piezoelectric ceramic and the novel small and special electric machine of ultrasonic vibration.The existing contact ultrasound electric machine is to promote the rotor running by the frictional force between stator and the rotor, has frictional dissipation between stator and the rotor.Useful life and running speed all are restricted, and highly necessary ask the material of stator and rotor that higher resistance to wear will be arranged, the cost height, and structure is also complicated.
Summary of the invention:
The objective of the invention is to, develop a kind of high rotating speed, long-life, simple in structure, cylinder non-contact ultrasound electric machine that cost is low, practical.
For achieving the above object, this cylinder non-contact ultrasound electric machine adopts stator and the discontiguous type of drive of rotor.Motor mainly is made up of stator module, rotor assembly and bracket component, is characterized in that installation by bracket component and rotor assembly makes between stator and the rotor to have certain clearance, directly contact between stator and the rotor.The stator module that concrete formation is described motor is that piezoelectric ceramic is pasted on the stator matrix, and the stator matrix is installed on the packing ring; The rotor matrix of described rotor assembly is installed on the output shaft by axle sleeve, and axle is installed on base and the cover plate by pair of bearings, makes between rotor assembly and the stator module and exists the gap; The sleeve of described bracket component places between cover plate and the base, between base and the cover plate, fixedlys connected with nut by screw rod, and a pair of packing ring is installed on respectively in the annulus boss of base and cover plate.
The present invention has adopted the noncontact type of drive, utilizes the gap between acoustic radiation pressure control stator and rotor, utilizes the sound viscous stress between stator and the rotor to drive rotor, thereby has obtained very high rotating speed and extremely long life-span.The restriction that the life-span of having broken through ultrasound electric machine is short, can only the gap use.

Embodiment:
The present invention is based on the novel ultrasound electric machine that utilizes piezoelectric ceramic piece to swash B (0,3) the mode acoustic radiation pressure harmony viscous stress of cylinder stator and be developed into.
It mainly contains stator module, rotor assembly and bracket component and forms.Fig. 1 is a concrete structure schematic diagram of the present invention, as seen from the figure, the stator module of motor is made up of with being pasted on four piezoelectric ceramic 7 in four uniform rectangular channels of stator outer surface of matrix stator matrix 10, with packing ring 4 interference fits that place in base 12 and the cover plate 2; And exist the rotor matrix 8 of the rotor assembly of certain interval to be installed on the output shaft 9 by axle sleeve 11 between the stator module, output shaft 9 is installed on cover plate 2 and the base 12 by pair of bearings 1, and wherein, rotor matrix 8 is an interference fit with axle sleeve 11; Bracket component be by screw rod 5 and nut 3 with cover plate 2, base 12 and place cover plate 2 and base 12 between sleeve 6 be fixed together, base 12 and cover plate 2 respectively have a dead eye, 1 pair of axle 9 of the bearing that is bumped into plays radial support effect and axial location effect.
Piezoelectric ceramic piece adopts four rectangular ceramic sheets, two-sided not subregion.Piezoelectric ceramic piece after the polarization is subjected to electric field action can produce distortion.The subregion that polarised direction is identical with direction of an electric field produces elongation strain, otherwise produces compression.When four potsherds apply successively sinwt, coswt ,-sinwt ,-during the alternating voltage of coswt, stator produces the rotation mode of B (0,3)---the row ripple.Because stator does not contact with rotor, the acoustic radiation pressure that produces in the air gap between rotor is given the certain suspending power of rotor, do not contact with stator when guaranteeing rotor rotation, and the effect of the sound viscous force that also exists in the air gap, as the frictional force drives rotor in the contact motor, the rotor of different is contact motor is by the anti-direction motion of row phase of wave, and contactless rotor is by the direction of row ripple unanimity.
Stator of the present invention does not contact with rotor, does not have fretting wear, thereby obtains the long-life of motor and very high speed running; Do not need friction material to improve the resistance to wear of rotor yet, simplify the structure, reduced cost.
