It is dynamic；The rotation of second planetary gear 10 can drive the second sun gear 17 to rotate；Due to the second sun gear of effect 17 of the second unidirectional ring 15
Rotation will not drive the 3rd fixing axle 19 to rotate；I.e. when the first planetary gear 9 rotates the 3rd fixing axle 19 when drive ring gear 4 rotates
The transmission of driving plate 20 is not interfered with；The first row can be driven when the second planetary gear 10 rotates ring gear 4 when drive ring gear 4 rotates
Star-wheel 9 rotates；The rotation of first planetary gear 9 can drive the first sun gear 14 to rotate；Due to first sun of effect of the first unidirectional ring 8
Wheel 14, which rotates, will not drive Z-type wheel to rotate；It is not interfered with when the second planetary gear 10 rotates Z-type wheel when drive ring gear 4 rotates
Drum 5 rotates.
Cylinder is respectively and fixedly installed to retainer ring 3 in fixed cylinder support 31 and retainer ring support 32 in the present invention, Neng Goubao
It demonstrate,proves drum 5, the stability that Z-type ring 7 is moved with ring gear 4, there is balance rotating drum 5Z type rings 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
It rotates and driving plate 20 is driven to be rotated around the axis of input shaft 6, driving plate 20, which rotates, drives arc strip 21 to rotate, when arc strip 21
When rotary 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 the 3rd fixing axle 19 to rotate, and the 3rd fixes
Axis 19 is rotated drives the second sun gear 17 to rotate by the second unidirectional ring 15；Second sun gear 17, which rotates, drives the second planetary gear 10
It rotates；Second planetary gear 10, which rotates, drives ring gear 4 to rotate；Ring gear 4 drives output shaft 13 to rotate；That is the rotation of input shaft 6 can
Output shaft 13 to be driven to rotate；When arc strip 21 is in high-speed motion, the centrifugal-block 24 in arc strip 21 is in centrifugal force
Under the action of to arc strip 21 outside move, centrifugal-block 24 in moving process when centrifugal-block 24 is contacted with drum 5, from
Heart block 24 can rub with drum 5, and centrifugal-block 24 departs from arc strip 21 at this time, but with the increase arc strip 21 of speed
Fixed reel 18 can be departed from, arc strip 21 in centrifugal-block 24 with closing；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 first sun gear 14 to revolve by the first unidirectional ring 8
Turn, the rotation of the first sun gear 14 drives the first planetary gear 9 to rotate；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 will not drive fixed reel
18 rotations；That is the rotation of input shaft 6 can drive output shaft 13 to rotate.
