Abstract
The invention provides a double-rotor radial driving meshing motor with low speed and large torque, which adopts magnetic poles with double-rotor structures to prevent occurrence of magnetic circuits coupling among all magnetic poles and reduce difficulty of magnetic field analysis; the opposite movement of an inner rotor and an external rotor not only can multiply electromagnetic force but also can neutralize inertia force and reduce vibration; a plurality of eccentric shafts are used for binging a translational mechanism which is composed of rotors, a rotor fixed bracket and a support so as to cause the radius of revolution running to be completely restricted, thereby preventing sliding displacement among gears and improving transmission efficiency. Furthermore, stators and the rotors of the motor of the invention are fixedly connected with an external gear and an internal gear circle respectively so as to form a reducer gear meshing transmission mode to reduce the speed, thus indeed integrating the motor and a reducer into a whole. In addition, the rotors relative to the stators only realize the translation in a tangential direction of a circumference, without rotation; and the weaknesses of long operating distance, slow response speed, unstable low-speed working condition and small output torque caused by the rotors of the motor with traditional structure relative to the stators rotate only one circle can be prevented.
Description
Technical field
The present invention relates to a kind of double-rotor radial driving meshing motor, exactly, relate to a kind of variation that utilizes magnetic resistance between stator and the rotor, convert electrical energy into mechanical energy, be aided with the secondary mechanism of eccentric shaft translation constraint again, make rotor do the translation of tangent to periphery direction, and drive the gearing motor of inside engaged gear reducing gear output low speed, big torque, belong to the driven by power apparatus technology by rotor around stator.
Background technology
In recent years, novel reducing gear and motor are being carried out all obtained good progress both at home and abroad aspect the incorporate developmental research.For example, the two combines motor and harmonic wave speed reducing machine, makes output torque increase and physical dimension significantly reduces.The Japan scientific and technical personnel adopt the deceleration transmission principle based on gears engaged, have developed the motor of multiple different types of structure.As the piezoelectricity cycloidal generator, it is the engagement by a pair of cycloid gear, and the stretching motion of piezoelectric actuator is converted to the rotation of rotor, relies on the actuating force of piezoelectric actuator output to promote the cycloidal generator rotation and output torque again.The speed reducing ratio of piezoelectricity cycloidal generator is its rotor and the ratio of difference with the number of teeth of rotor of the stator number of teeth, and speed reducing ratio is very high.Simultaneously, little because of the friction loss of meshed transmission gear, transmission efficiency is high, so the piezoelectricity cycloidal generator compares with harmonic motor with the ultrasonic wave that relies on frictional force between the rotor to export the slow-speed of revolution, high pulling torque, the former efficient height, longer service life.
In recent years, because the advantage of meshed transmission gear, successively succeed in developing the multiple low-speed big motor that gears engaged is combined with dissimilar driver.For example the cycloidal generator that drives by rubber deformation, the bevel gear motor by air cylinder driven, rely on face gear motor, electromagnetism cycloidal generator and electromagnetism bevel gear motor of Driven by Hydraulic Cylinder or the like.Above-mentioned motor all has the efficient height, precision is good, wearing and tearing are little, volume is little, the advantage of compact conformation, and has obtained good application in the drive unit of robot.
But, above-mentioned various motors mostly be with driver directly and rotor, stator interconnect, do not form integrated mechanism, so structure is still not compact.Adopt the motor of cylinder and Driven by Hydraulic Cylinder, except needs driven by power equipment, also need extra compressed air or hydraulic pressure as power source.The motor that piezoelectricity or giant magnetostrictive material drive is then lacked very much (only being micron order) because of the effect stroke of its driver, is difficult to possess practical value.For satisfying the actual demand of stator movement stroke, also to increase by a cover lever, to increase its effect stroke.Yet the motor that is used for the bigger occasion of driven at low speed and load all will be installed decelerator and associated components thereof, has so just increased the member and the weight of drive unit, and structure is too complicated, impracticable.
