Dynamic planetary gear 30 is rotated according to planetary gear direction of rotation 90.Planet stent direction of rotation 84 and bidentate gear ring direction of rotation 86
On the contrary, being object of reference with bidentate gear ring 23, planet stent 7 is that bidentate gear ring 23 rotates relative to the rotary speed of bidentate gear ring 23
The sum of speed and 7 rotary speed of planet stent, the sum of the rotary speed acts on planetary gear 30, and driving sun gear 26 is pressed
It is rotated according to 92 high rotating speed of sun gear direction of rotation, sun gear direction of rotation 92 is identical as planet stent direction of rotation 84, real
Existing variable speed and speedup function.
In the speed increaser operational process, the output rotating speed of output shaft is 23 rotary speed of bidentate gear ring and planet stent
The sum of 7 rotary speeies act on planetary gear 30, the speed that driving sun gear 26 rotates, and output shaft output rotating speed is more than
Planet stent rotary speed acts on planetary gear the speed for driving sun gear rotation in common planetary gear speed increaser.It adjusts
9 position of section shift fork can change the output rotating speed of the output shaft of the speed increaser, and big, speed increasing ratio can with speed increasing ratio for the speed increaser
The advantages of to adjust.In the speed increaser operational process, motor is in the same direction of rotation high-speed cruising state always, really
Motor is protected to run under the higher working condition of efficiency.

(26) rotating speed rotated；
The speed increaser operational process is：
When the speed increaser operation, planet stent (7) rotation of motor drive planetary gear member adjusts shift fork (9) position,
Make to move in the axial direction in gap of the steel ball (10) between cone pulley one (3) and cone pulley two (15) outer surface, planet can be changed
Speed discrepancy between holder (7) and shaft two (12)；A part of mechanical kinetic energy of motor input is driven by planet stent (7)
The planetary gear (30) of planetary gear member is rotated according to planetary gear direction of rotation (90), and another part mechanical kinetic energy passes through row
The steel ball (10) of cone pulley one (3) shift fork component of star geared parts rotates, the cone pulley of steel ball (10) drive shaft component two
Two (15) rotate, and cone pulley two (15) drives linkage gear (20) to rotate by the shaft two (12) of rotating axis component two, linkage gear
(20) driving bidentate gear ring (23) rotates, and bidentate gear ring (23) drives planetary gear (30) according to planetary gear direction of rotation (90)
Rotation；On the contrary, with bidentate gear ring (23) for object of reference, go with bidentate gear ring direction of rotation (86) planet stent direction of rotation (84)
Prong frame (7) is that bidentate gear ring (23) rotary speed is rotated with planet stent (7) relative to the rotary speed of bidentate gear ring (23)
The sum of speed, the sum of the rotary speed act on planetary gear (30), and driving sun gear (26) is rotated according to sun gear
The high rotating speed rotation in direction (92), sun gear direction of rotation (92) are identical as planet stent direction of rotation (84), realize stepless change
Speed and speedup function.
