Operation principle of the present invention is: after the motor energising, kicker magnet 10 on the magnetomotive force that winding electric current on the cylindrical shell 4 inwall silicon steel sheets 7 of its shell stator 1 produces and housing 9 outer surfaces of rotor 2 interacts, thereby make rotor along clockwise or rotate counterclockwise, and housing 9 drives left ratchet seat 14 and rotates simultaneously, by controlling outer operator, make outer push rod 28 and middle push rod 26 inside and outside flexible, thereby promote left speed governing cover 30 and right speed governing cover 29, make left and right speed governing cover 30,29 be in diverse location.According to the effect that residing diverse location and planetary gear mechanism are overlapped in speed governing, make long very heavy full interlock or the relieving of an end interlock one end or decontrol three kinds of states entirely, form three kinds of friction speeds.When left and right speed governing cover 30,29 is in extreme right position, very heavy 38, the 35 full interlocks of left and right length, this moment, motor was slow shelves velocity of rotation; When left and right speed governing cover 30,29 was in the centre position of through hole, the left side on the left ratchet seat 14 long very heavy 38 was decontroled, long very heavy 35 interlocks in the right side on the right ratchet seat 13, and this moment, motor was middle-grade velocity of rotation; When left and right speed governing cover 30,29 was in the left end extreme position, left and right length very heavy 38,35 was decontroled entirely, and this moment, motor was fast shelves velocity of rotation.Slowly, in, the concrete drive connection of fast third gear is as follows:
1, the transmission of slow shelves: the rotation of energising back casing 9 drives left ratchet seat 14 and rotates, 43 interlocks are enclosed with the outer sour jujube in a left side in a left side long very heavy 38, skid in a left side short very heavy 36, thereby the left very heavy axle 37 that is fixed on the right ratchet seat 14 is rotated, the rotation of the very heavy axle 37 in a left side drives the outer sour jujube circle 43 in a left side and rotates, the interlock of enclosing the Baltimore groove of the boss structure of 43 end faces and gear ring 32 by sour jujube outside the left side is rotated gear ring 32 then, the rotation of gear ring 32 drives the rotation of planetary gear 23, and this moment right long very heavy 35 and right inner spinous ring 40 interlocks, right weak point very heavy 36 encloses 41 interlocks with right outer sour jujube, but because very heavy effect, right outer sour jujube circle 41 skids, and right inner spinous ring 40 rotates, and makes planet carrier 31 do retarded motion, thereby makes the transmission of the slow shelves of right ratchet seat 13 outputs.
2, middle-grade transmission: the rotation of energising back casing 9 drives left ratchet seat 14 and rotates, a left side long very heavy 38 is decontroled, the outer sour jujube circle 43 in a left side skids, a left side short very heavy 39 and left inner spinous ring 42 interlocks, the interlock of the Baltimore groove of boss structure by left inner spinous ring 42 end faces and planet carrier 31 is rotated planet carrier 31 then, this moment right long very heavy 35 and right inner spinous ring 40 interlocks, right short very heavy 36 decontrol, because very heavy effect, right outer sour jujube circle 41 skids, right inner spinous ring 40 rotates, and planetary gear 23 is done rotation and revolution, thereby makes the equal rotating speed of right ratchet seat 13 outputs.
3, fast shelves transmission: the rotation of energising back casing 9 drives left ratchet seat 14 and rotates, a left side long very heavy 38 is decontroled, the outer sour jujube circle 43 in a left side skids, a left side short very heavy 39 and left inner spinous ring 42 interlocks, the interlock of the Baltimore groove of boss structure by left inner spinous ring 42 end faces and planet carrier 31 is rotated planet carrier 31 then, decontrol this moment right long very heavy 35, right weak point very heavy 36 encloses 41 interlocks with right outer sour jujube, because very heavy effect, right inner spinous ring 40 skids, and right outer sour jujube circle 41 rotates, and planetary gear 23 is done rotation and revolution, gear ring 32 rotates and speedup, thereby makes the transmission of the fast shelves of right ratchet seat 13 outputs.
