14 rotation of wheel not will drive the rotation of Z-type wheel；I.e. when the second planetary gear 10 rotates, and ring gear 4 is driven to rotate, Z-type wheel be will not influence
Drum 5 rotates.
Cylinder and fixed ring 3 are respectively and fixedly installed in fixed cylinder support 31 and fixed ring support 32 in the present invention, Neng Goubao
The stability that drum 5, Z-type ring 7 and ring gear 4 move is demonstrate,proved, has the function of balance rotating drum 5Z type ring 7 and ring gear 4.This
Fixed cylinder 2 plays support to drum 5 and Z-type ring 7 in invention.
Specific embodiment；When the speed changer that people are designed using the present invention, when above-mentioned input shaft 6 rotates, input shaft 6
Rotation drives driving plate 20 to rotate around the axis of input shaft 6, and the rotation of driving plate 20 drives arc strip 21 to rotate, when arc strip 21
When rotation speed is smaller, centrifugal-block 24 is subject to centrifugal forces smaller at this time, and arc strip 21 is in fixed reel 18
Gripping orientation, arc strip 21 can drive fixed reel 18 to rotate；Fixed reel 18 drives third fixing axle 19 to rotate, and third is fixed
The rotation of axis 19 drives the rotation of the second sun gear 17 by the second unidirectional ring 15；The rotation of second sun gear 17 drives the second planetary gear 10
Rotation；The rotation of second planetary gear 10 drives ring gear 4 to rotate；Ring gear 4 drives output shaft 13 to rotate；That is the rotation of input shaft 6 can
To drive output shaft 13 to rotate；When arc strip 21 is in high-speed motion, the centrifugal-block 24 in arc strip 21 is mounted in centrifugal force
Under the action of it is mobile to the outside of arc strip 21, centrifugal-block 24 in moving process when centrifugal-block 24 and drum 5 contact, from
Heart block 24 can rub with drum 5, and centrifugal-block 24 and arc strip 21 are detached from this time, but with the increase arc strip 21 of speed
It can be detached from fixed reel 18, closed in arc strip 21 and centrifugal-block 24；Arc strip 21 is driven by the friction of centrifugal-block 24 and drum 5
Dynamic drum 5 rotates, and the rotation of drum 5 drives the rotation of Z-type wheel；The rotation of Z-type wheel drives the rotation of the first sun gear 14 by the first unidirectional ring 8
Turn, the rotation of the first sun gear 14 drives the rotation of the first planetary gear 9；First planetary gear 9 drives ring gear 4 to rotate；Ring gear 4 drives
Output shaft 13 rotates；Since arc strip 21 has been detached from fixed reel 18 at this time, so arc strip 21 not will drive fixing axle disk
18 rotations；That is the rotation of input shaft 6 can drive output shaft 13 to rotate.
