It is equipped with floating idler pulley on input shaft, the floating idler pulley on the wide V band connections motor output shaft and reducer input shaft.
During using above-mentioned technical proposal, start motor, the output shaft rotation of motor, because motor output shaft and subtracting
It is equipped with floating idler pulley on fast device input shaft, the floating idler pulley on wide V band connections motor output shaft and reducer input shaft, institute
Rotated with transmission input shaft under the drive of wide V bands, the groove width of floating idler pulley is adjusted by adjusting means, just can continuously be changed
Gearratio, power are inputted from reducer input shaft, exported after then being slowed down by decelerator, are now exported from decelerator output end
Rotating speed can realize and continuous change gearratio.Groove width of the invention by changing floating idler pulley, so as to realize that continuous change passes
Dynamic ratio；In addition, this programme eliminates the mode for fully relying on change gear box speed change, it is not necessary to multi-change speed, so overall
Small volume.
Further, the floating idler pulley on the motor output shaft is variable slot broadband wheel, on reducer input shaft can
Rigger is determines groove width belt wheel, and the adjusting means includes stage clip, movable plate and adjusting rod, and the movable plate is slidably connected at electricity
On motivation output shaft, stage clip is set on motor output shaft, and stage clip one end and the movable pulley outside in the wheel of variable slot broadband
End face offsets, and the other end offsets with movable plate side, and movable plate opposite side offsets with adjusting rod.Movable plate is adjusted by adjusting rod
In sliding axially for input electric motor shaft, so as to control stage clip to deform, finally control in the floating idler pulley on motor output shaft
Movable pulley slip, the groove width of floating idler pulley can just be changed by sliding slipping, so as to continuously change gearratio.
Further, described reducer input shaft one end is connected on bottom end cover by bearing, and the other end is connected by bearing
On lower box.The both ends of reducer input shaft are connected by bearing, so the radial shear power that reducer input shaft is born
Small, reducer input shaft is not susceptible to deform.
Further, the floating idler pulley on the motor output shaft and reducer input shaft is variable slot broadband wheel.This
The slewing range of kind mode is bigger.
Brief description of the drawings
Fig. 1 is the schematic diagram of stepless speed change device embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Motor 1, motor output shaft 2, upper box 3, movable plate 4, regulation
Bar 5, upper end cover 6, variable slot broadband take turns 7, determine groove width belt wheel 8, wide V bands 9, bottom end cover 10, lower box 11, bearing 12, decelerator
13rd, reducer input shaft 14.
As shown in figure 1, a kind of stepless speed change device, including motor 1 and decelerator 13, separating box is additionally provided with, can
Rigger, wide V bands 9 and adjusting means, separating box include the upper box 3 and lower box 11 being connected, and upper box 3 is connected to
The output end of motor 1, the outside of upper box 3 are provided with upper end cover 6, and motor output shaft 2 is rotatablely connected with upper end cover 6, lower box 11
The input of decelerator 13 is connected to, the outside of lower box 11 is provided with bottom end cover 10,10 turns of input shaft 14 and the bottom end cover of decelerator 13
