Fig. 3 transfers, becomes (subtracting) electric motor with speed for permanent power alternating electromagnetic, its structure is to adorn a drive bearing 11 that plays decelerating effect at the output of the drive bearing 3 of doing the differential attachment use, axle 12 is connected with the centre circle of drive bearing 3 and the inner ring of drive bearing 11 respectively, and the centre circle of drive bearing 11 is connected with spring coupling.
Fig. 4 transfers (subtracting) fast device for the permanent power alternating electromagnetic that alternating electromagnetic transfers (subtracting) electric motor with speed to derive from, and its structure is that permanent power alternating electromagnetic transfers (subtracting) electric motor with speed (Fig. 1) to remove motor 1, and replaces motor with power shaft 12 and supporting member thereof.
In like manner, can transfer that (increasing) electric motor with speed, permanent power alternating electromagnetic are transferred by permanent power alternating electromagnetic, varying speed motor derives corresponding permanent power electromagnet and transfers (increasing) fast device and accent, speed changer.
Operation principle of the present invention is as follows: in the sun gear of cyclic train, ring gear, planet carrier three members, sun gear or ring gear are appointed and are fixed one, and wheel is an epicyclic transmission; Unfixing when three members, this train becomes the gear differential attachment.Differential attachment can synthesize a motion to two motions.The operation principle of the drive bearing that is adopted in the structure of the present invention is similar to planetary reducer.It is fixing ring gear (outer ring), will move by two eccentric bushings (inner ring) input, by the stable drive ratio reducing gear of transmission circle (centre circle) output.When the present invention makes power transmission shaft differential attachment and uses, it outer, in, inner ring is fixing, by two member input motions wherein, another member output movement.One is the motion of electromagnetic slip clutches in above-mentioned two motions, and another is the motion of motor (or other power machines).The motion of electromagnetic slip clutches is imported by the drive bearing outer ring.The motion input of motor (or other power machines) and resultant motion output fibrous root according to transfer, the scope of speed change request adopts inner ring respectively or centre circle as the member of input and output campaign.Be output as deceleration with inner ring input centre circle, be output as speedup with centre circle input inner ring.The rotating speed of the resultant motion of output is wanted further step-down or is uprised, and passes through one or several drive bearing speed change again.
Transfer in (subtracting) electric motor with speed at the permanent power alternating electromagnetic of Fig. 1, the inner ring that motor 1 rotating shaft drives armature 2 and drive bearing 3 rotates with normal speed, logical variable direct current in the magnet exciting coil 7, polarization on the tooth utmost point 4, this polarity magnetic line of force produces current vortex on the armature 2 of rotation.Current vortex on the tooth utmost point 4 magnetic lines of force and the armature 2 interacts, and the outer ring input of a difference rotary speed from drive bearing 3 arranged.When motor was 4 utmost points, the drive bearing inner ring was the rated speed 1450r/min of 4 utmost point asynchronous motors, and the outer ring is electromagnetic slip clutches rotating speed (120-1200r/min).When selecting the existing internal tooth of drive bearing for use is 59 product, and according to the drive connection of differential gear train, drive bearing centre circle output speed scope is 8.5: 1 for the 142-1204r/min. speed ratio.
Because asynchronous motor is with rated speed direct and load coupling by differential attachment, electromagnetic slip clutches only play a part to change the differential attachment transmission speed, so the present invention is constant output characteristic in speed adjustable range.
Because the allocation proportion of power draw on electromagnetic slip clutches of load is very little, so the variation of load is little to its rotating speed influence, and is the part of resultant motion, therefore NATURAL MECHANICAL PROPERTIES hardening of the present invention.
