Capping 4 tops are connected by the screw thread tight fit with rotor case 1, and capping 4 belows are rotatably connected by steel ball 5 and right ratchet seat 7; Rotor case 1 is connected with left ratchet seat 6 interference fit.The rolling bearing I8 that is equipped with on the outer cylinder surface of the endoporus of described right ratchet seat 7 and axis 3 forms to roll and is connected; The rolling bearing II9 that is equipped with on the outer cylinder surface of the endoporus of described left ratchet seat 6 and axis 3 forms to roll and is connected.In addition, jump ring I10 and the jump ring II11 that acts on rolling bearing I8 and rolling bearing II9 arranged between the outer cylinder surface of the utility model rotor case 1 and axis 3.
Speed adjusting gear is installed in the axis 3, and is subjected to the control of peripheral operation device (not shown).Described speed adjusting gear from left to right comprises screw 13, spring 14, left pin 17, middle push rod 16, right pin 15 and outer push rod 18 successively.Right pin 15 and left pin 17 are pressed into respectively in the right speed governing cover 19 and left speed governing cover 20 that is contained on the axis after passing through hole 36 on the axis 3, thereby limit right speed governing cover 19 and left speed governing cover 20 slides in the length of through hole 36, reach the purpose of governing speed.The front end of right speed governing cover 19 and left speed governing cover 20 is a cone structure, and front end of the present invention refers to that the left side of figure is a front end.
The planetary gear 23 that can be meshed with central gear 12 and gear ring 22 simultaneously is housed in the planet carrier 21 in the planetary gear mechanism, planetary gear 23 is installed on the planet pin 24 and with its moving joining and is connected, and the two ends close-fitting of planet pin 24 is on planet carrier 21, and gear ring 22 and planet carrier 21 both sides all are processed with Baltimore groove.
Operation principle of the present invention is: magnetomotive force and the kicker magnet on rotor case 1 outer surface 2 that the winding electric current on the energising rear casing stator produces interact, thereby make rotor along clockwise or rotate counterclockwise, meanwhile rotor case 1 drive left ratchet seat 6 rotates simultaneously, by controlling outer operator, make outer push rod 18 and middle push rod 16 inside and outside flexible, thereby promote right speed governing cover 19 and left speed governing cover 20, make left and right speed governing cover 20,19 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 20,19 is in extreme right position, very heavy 29, the 26 full interlocks of left and right length, this moment, motor rotor was slow shelves velocity of rotation; When left and right speed governing cover 20,19 was in the centre position of through hole 36, the left side on the left ratchet seat 6 long very heavy 29 was decontroled, long very heavy 26 interlocks in the right side on the right ratchet seat 7, and this moment, motor rotor was middle-grade velocity of rotation; When left and right speed governing cover 20,19 was in the left end extreme position, left and right length very heavy 29,26 was decontroled entirely, and this moment, motor rotor 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 rotor case 1 drives left ratchet seat 6 and rotates, 34 interlocks are enclosed with the outer sour jujube in a left side in a left side long very heavy 29, skid in a left side short very heavy 30, thereby the left very heavy axle 28 that is fixed on the right ratchet seat 7 is rotated, the rotation of the very heavy axle 28 in a left side drives the outer sour jujube circle 34 in a left side and rotates, the interlock of enclosing the Baltimore groove of the boss structure of 34 end faces and gear ring 22 by sour jujube outside the left side is rotated gear ring 22 then, the rotation of gear ring 22 drives the rotation of planetary gear 23, and this moment right long very heavy 26 and right inner spinous ring 31 interlocks, right weak point very heavy 27 encloses 32 interlocks with right outer sour jujube, but because very heavy effect, right outer sour jujube circle 32 skids, and right inner spinous ring 31 rotates, and makes planet carrier 21 do retarded motion, thereby makes the slow shelves of right ratchet seat 7 outputs rotating speed.
2, middle-grade transmission: the rotation of rotor case 1 drives left ratchet seat 6 and rotates, a left side long very heavy 29 is decontroled, the outer sour jujube circle 34 in a left side skids, a left side short very heavy 30 and left inner spinous ring 33 interlocks, the interlock of the Baltimore groove of boss structure by left inner spinous ring 33 end faces and planet carrier 21 is rotated planet carrier 21 then, this moment right long very heavy 26 and right inner spinous ring 31 interlocks, right short very heavy 27 decontrol, because very heavy effect, right outer sour jujube circle 32 skids, right inner spinous ring 31 rotates, and planetary gear 23 is done rotation and revolution, thereby makes the equal rotating speed of right ratchet seat 7 outputs.
3, fast shelves transmission: the rotation of rotor case 1 drives left ratchet seat 6 and rotates, a left side long very heavy 29 is decontroled, the outer sour jujube circle 34 in a left side skids, a left side short very heavy 30 and left inner spinous ring 33 interlocks, the interlock of the Baltimore groove of boss structure by left inner spinous ring 33 end faces and planet carrier 21 is rotated planet carrier 21 then, decontrol this moment right long very heavy 26, right weak point very heavy 27 encloses 32 interlocks with right outer sour jujube, because very heavy effect, right inner spinous ring 31 skids, and right outer sour jujube circle 32 rotates, and planetary gear 23 is done rotation and revolution, gear ring 22 rotates and speedup, thereby makes the fast shelves of right ratchet seat 7 outputs rotating speed.
