Abstract
The invention relates to a magnetic induction type magnetic transmission device which comprises a power input shaft, a driving permanent magnet turntable, a driven magnetic induction turntable and a power output shaft, wherein the power input shaft is arranged at the rotating center of the driving permanent magnet turntable to be in driving connection with the driving permanent magnet turntable, the driving permanent magnet turntable is formed by a turntable body made of permeability magnetic materials and a plurality of permanent magnets embedded in the turntable body, and a clearance is arranged between the driving permanent turntable and the driven magnetic induction turntable. When load on a belt wheel on the driven magnetic induction turntable exceeds magnetic force driving force, the driven turntable is blocked, the motor connected with the driving permanent magnet turntable rotates continuously, the phenomenon of blocking cannot happen, and safety of the motor can be ensured. Simultaneously, by regulating the rotating speed of the motor, constant torque and driving can be output, and the magnetic induction type magnetic transmission device has meaningful functions in various occasions and is particularly suitable for application in the field of robots and health care massage device manufacture.
Description
Technical field:
The present invention relates to mechanical drive technology field, it is a kind of non-contacting magnetic inductive magnetic transmitter, be mainly used in the torque that needs regulation output constant, can be in for a long time in the equipment of stall operating state, be specially adapted to the manufacturing field of robot.
Background technology:
The magnetic drives technology has been widely used in various contactless powerdriven connections.Magnetic drive device is that the two like magnetic poles repel each other according to magnetic material, the characteristic that there is a natural attraction between the sexes are come work, and it drives outer magnet rotor rotation with the power of prime mover by its axle, thereby magnet rotor rotation in driving has realized contactless transmission.
In existing magnetic drive technology, the corresponding coupling of permanent magnet of magnet rotor realizes Synchronous Transmission inside and outside most of the employing, i.e. inside and outside magnet rotor motion be in the same way, synchronously, with speed, the rotating speed of its output can be realized by the rotating speed of regulating prime mover, but the torque of output is to regulate, so there is in the use limitation.Existing and less in the at present research of magnetic inductive drive method, and substantially be applied in pump and the stirring, and volume is all larger, substantially is not applied in the small size magnetic induction driver in the robot.
Summary of the invention:
The invention provides a kind of magnetic inductive magnetic drive device.By regulating the rotating speed of prime mover, reach and regulate the initiatively rotating speed of permanent magnet rotating disk, realize faradic size from the dynamic magnetic induction rotating disk, namely change the size of induced field, thereby reach the purpose of control output level of torque, when active permanent magnet rotary speed was fixed as a certain numerical value, the output torque on its driven rotating disk was a steady state value.This characteristic is particularly applicable in robot and therapeutic massage equipment manufacturing field.
Technical scheme of the present invention is as follows: it is characterized in that: it comprise power input shaft, initiatively the permanent magnet rotating disk, from dynamic magnetic induction rotating disk and power output shaft; Described power input shaft be positioned at permanent magnet rotating disk initiatively center of rotation, be connected with permanent magnet rotating disk driving initiatively, described active permanent magnet rotating disk consists of rolling disc by non-magnet material and several permanent magnets of being embedded in this rotating disk consist of, and is provided with the gap at active permanent magnet rotating disk and between the dynamic magnetic induction rotating disk;
Describedly be formed by stacking by copper sheet, aluminium flake or other non-magnetic sheet metals and permeability magnetic material from the dynamic magnetic induction rotating disk, be fixed with power-take-off pulley in the side from the dynamic magnetic induction rotating disk; Be movably connected on the power input shaft by bearing from the dynamic magnetic induction rotating disk.
During the work of this magnetic inductive magnetic drive device, drive power input shaft by drive motors by shaft coupling, deceleration device and be rotated motion, driven simultaneously the initiatively rotation of permanent magnet rotating disk, thereby make from the dynamic magnetic induction rotating disk and produce induced current and magnetic field, thereby realized the magnetic couple rotation, and outputed power by the belt pulley from the dynamic magnetic induction rotating disk.By regulating the rotating speed of drive motors, can reach control from the power in the faradic size of dynamic magnetic induction rotating disk and magnetic field, thereby reach the purpose that changes the output level of torque.When active permanent magnet rotary speed was fixed as a certain numerical value, the output torque on its driven rotating disk was a steady state value.
When traditional machenical coupling surpasses the motor nominal load when load, motor will be blocked then burn or protected quitting work; And inside and outside permanent magnet magnetic force actuators by the permanent magnet formation, its rotating speed is adjustable but the torque of its output is unadjustable.If initiatively the magnetic coupling force of permanent magnet rotating disk and driven permanent magnet rotating disk is greater than the actuating force of motor, motor will be blocked then burn; If initiatively the magnetic coupling force of permanent magnet rotating disk and driven permanent magnet rotating disk is less than the actuating force of motor, then motor can not be blocked with driven permanent magnet rotating disk then produce the stall phenomenon, motor continues to drive initiatively permanent magnet turntable rotation, at this moment, if the quantity of the magnet distribution initiatively on permanent magnet rotating disk and the driven permanent magnet rotating disk is insufficient, be that magnet pitch spaced apart is larger, namely can produce and jump or the side effect phenomenon of vibration.And belt pulley load from the dynamic magnetic induction rotating disk of the present invention is when surpassing magnetic drive power, driven rotating disk will be by stall, and the motor that is connected with active permanent magnet rotating disk also will continue rotation, the stall phenomenon can not occur, namely guarantee motor safety, simultaneously by the rotating speed of regulating electric machine, can reach output constant torque and actuating force, this has the extremely purposes of meaning in a lot of occasions, is specially adapted to the application that robot and therapeutic massage equipment are made the field.
