700, the number of teeth of each gear in the present embodiment is given below, it should be understood that the number of teeth of each gear can root in other embodiments
According to needing to change.
Spare part electroplax pads 110 teeth of tooth cover board 1--- external tooths/circle；Spare part electroplax pads 80 teeth of tooth plate 2--- internal tooths/circle；Spare part row
27 teeth of star-wheel 3--- external tooths/circle；40 teeth of spare part sun gear 4--- external tooths/circle, 70 teeth of internal tooth/circle；70 tooth of axis servomotor 5--- external tooths/
Circle；40 teeth of sun gear 6--- external tooths/circle, 70 teeth of internal tooth/circle；27 teeth of planetary gear 7--- external tooths/circle；Electroplax pads tooth plate 8--- internal tooths
80 teeth/circle；79 teeth of parcel chain wheel 550--- internal tooths/circle；Retainer 10.It should be understood that the number of teeth and transmission ratio can as needed into
Row selection.
Basic principle is:Electronic governing system engages spare part electroplax by the pinion gear on servomechanism 800 and pads tooth cover board 1,
Because spare part electroplax pad tooth cover board 1 is fixed with spare part electroplax pad tooth plate 2 for bolt, power engagement is transmitted to spare part planetary gear 3, then
To spare part sun gear 4, and the internal tooth of spare part sun gear 4 is meshed with the external tooth of axis servomotor 5, and the inner cavity of axis servomotor 5 passes through
The bearing of retainer 10 is connected with the sliding of entering spindle 230, and it is supported individually to operate, and the external tooth of the other end of axis servomotor 5
Be meshed with sun gear 6, and sun gear 6 is meshed with planetary gear 7, because across the electroplax pad tooth plate of the gear thickness of planetary gear 78 with
The thickness of 550 liang of teeth of parcel chain wheel, and engaged simultaneously with two teeth, and electroplax pad tooth plate 8 is fixed with chuck 540 for bolt, parcel
Chain wheel 550 is free to rotate with chuck 540, and electroplax pad tooth plate 8 has teeth number difference with 550 liang of teeth of parcel chain wheel, therefore works as planetary gear 7
When rotating a circle, parcel chain wheel 550 tooth plate 8 will be padded than electroplax and chuck more than 540 or few turns the distance of a tooth, so electronics tune
Speed system can adjust the Archimedes on parcel chain wheel 550 by the speed of the reversion of the rotating forward on servomechanism 800 and rotating speed
Helical involute parcel flat thread, and the plane thread of claw 510 is engaged with, and makes claw 510 in the radius of chuck 540
Direction moves, to change the diameter of variable chains wheel plate 560.
After 800 end sensor of servomechanism measures the rotating speed of chuck 540, along with when active transmission device 500 and driven
When variable chains wheel plate 560 in transmission device 700 is that diameter is identical, rotating speed is also identical.
Assuming that as soon as the parcel chain wheel 550 in active transmission device 500 turns the distance of teeth than chuck more than 540 or few,
It is the rotating speed in the rotating ratio chuck 540 of servomechanism 800 per turning around as (0.25mm/ circles), it is assumed that when actively transmission more
When 540 rotating speed of chuck in device 500 is 1000 turns, servo motor rotating speed is 1100 turns, then the radius of variable chains wheel plate 560 is just
Become larger 25mm, and slave drive device 700 is then on the contrary, servo motor rotating speed is 900 turns, then the radius of variable chains wheel plate 560 is just
Become smaller 25mm.And the perimeter as the chain of intermediate transfer belt 430 is constant always, it is stepless to change mechanical variable sprocket wheel
The transmission ratio of speed changer 900.
Servomechanism 800 drives parcel chain wheel 550 by driving electroplax to pad tooth plate.Specifically, speed governing is by servo motor
The parcel chain wheel 550 in 540 body of chuck to control active transmission device 500 and slave drive device 700 in high-speed rotation,
Parcel chain wheel 550 does the big minor radius action of self-centering and displacement, is done by the fixed variable sprocket wheel 560 being loaded on claw 510
The stepless variation of size diameter engages transmission movement to make to generate between variable chains wheel plate 560 and roller chain.
It should be understood that in other embodiments, servomechanism 800 can directly drive parcel chain wheel 550, parcel chain wheel 550 drives
Dynamic claw 510, claw 510 drive variable chains wheel plate 560 to change the diameter of variable chains wheel plate 560；Servomechanism 800 can also lead to
It crosses other transmission systems and either directly or indirectly drives parcel chain wheel 500.
In one example, input unit 200 rotates 1000 turns, then 800 end sensor measuring rotating speed of servomechanism is about 51
The right side of turning left synchronizes, as long as the rotating speed that servomechanism 800 rotates is more than 51 turns or can all make active transmission device 500 less than 51 turns
Or the diameter of the variable chains wheel plate 560 on slave drive device 700 becomes larger or becomes smaller, it is assumed that active transmission device 500 can be changed
The minimum diameter of chain wheel plate 560 becomes 100mm, and the maximum of the variable chains wheel plate 560 on slave drive device 700 at this time is straight
Diameter becomes 200mm.The change of (it is presetting program control that electricity, which adjusts control system) with minimum diameter to maximum gauge for 100mm
