Determine in ring and can the rotational slide in retainer ring, disk is mounted on ring gear one side;Output shaft is mounted on disk;Second row
Star-wheel, which rotates, drives ring gear rotation;Ring gear drives output shaft rotation.
Input shaft is mounted in input shaft support in the present invention, and the one side of driving plate is mounted on input shaft in centre position
On;When input shaft rotates, input shaft, which rotates, drives driving plate to be rotated around the axis of input shaft, the both ends of driving plate opposite side
It is separately installed with first straight pin;Driving plate is separately installed with two arc strips by two the first straight pins, for it
In any one arc strip, the first cylinder not being connected with one end of the first cylinder pin connection close to another arc strip
Pin;Driving plate, which rotates, drives arc strip to rotate, and when arc strip is in high-speed motion, arc strip is towards the arcwall face of the one side of drum
On equably open successively there are six eccentric groove;Six centrifugal-blocks are separately mounted in six eccentric grooves;The bottom of each eccentric groove
Centrifugal-block fixed spring there are one being installed respectively between corresponding centrifugal-block;Centrifugal-block in arc strip is in centrifugal force
Under the action of to arc strip outside move, centrifugal-block in moving process when centrifugal-block is contacted with drum, centrifugal-block meeting
It rubbing with drum, centrifugal-block departs from arc strip at this time, but can depart from fixed reel with the increase arc strip of speed,
Arc strip in centrifugal-block with closing;Drum and Z-type ring are consolidated by being fixed on cylinder on cylinder its inner wall, and fixed cylinder passes through fixed cylinder branch
On a mounting board, the one side one side installation do not protruded on Z-type ring has drum and is connected with the one side of drum, Z for support fixed installation
The periphery of type ring is mounted on the inner headed face of fixed cylinder;Arc strip drives drum to revolve by the friction of centrifugal-block and drum
Turn, drum rotation drives the rotation of Z-type wheel;The circumferential one side for being uniformly mounted on fixed cylinder of three the first fixing axles;Three the second rows

Wheel is engaged with three the first planetary gears, and three the first planetary gears are engaged with ring gear;The rotation of Z-type wheel passes through the first unidirectional annulus
Dynamic first sun gear rotation, the rotation of the first sun gear drive the rotation of the first planetary gear;Ring gear is mounted in retainer ring and can be with
The rotational slide in retainer ring, disk are mounted on ring gear one side;Output shaft is mounted on disk;First planetary gear drives internal tooth
Circle rotation;Ring gear drives output shaft rotation;Since arc strip has been detached from fixed reel at this time, so arc strip will not drive
Fixing axle disc spins.
When the first planetary gear rotates ring gear when drive ring gear rotates the second planetary gear can be driven to rotate in the present invention;The
The rotation of two planetary gears can drive the second sun gear to rotate;Since the second sun gear of effect rotation of the second unidirectional ring will not drive the
Three fixing axles rotate;The 3rd fixing axle does not interfere with the biography of driving plate i.e. when the rotation drive ring gear rotation of the first planetary gear
It passs;When the second planetary gear rotates ring gear when drive ring gear rotates the first planetary gear can be driven to rotate;First planetary gear rotates
The first sun gear can be driven to rotate;Since the first sun gear of effect rotation of the first unidirectional ring will not drive Z-type wheel to rotate;Work as
Second planetary gear rotates Z-type wheel when driving ring gear rotation and does not interfere with drum rotation.
Fixed cylinder is respectively and fixedly installed to fixed cylinder support with that in retainer ring support, can ensure with retainer ring in the present invention
Drum, Z-type ring and the stability of ring gear movement, play an important role of balance rotating drum Z-type ring and ring gear.It is solid in the present invention
Safety barrel plays support to drum and Z-type ring.
When people using the present invention design speed changer when, when input shaft rotates, input shaft rotate drive driving plate around
The axis for input shaft rotates, and driving plate, which rotates, drives arc strip to rotate, when arc strip rotary speed is smaller, centrifugal-block at this time
Subject to centrifugal forces smaller, arc strip is in gripping orientation with fixed reel, and arc strip can drive fixed reel to turn
It is dynamic;Fixing axle disk drives the 3rd fixing axle to rotate, and the 3rd fixing axle is rotated moves the rotation of the second sun gear by the second unidirectional annulus;
Second sun gear, which rotates, drives the second planetary gear to rotate;Second planetary gear, which rotates, drives ring gear rotation;Ring gear drives output
Axis rotates;That is input shaft rotation can drive output shaft to rotate;When arc strip is in high-speed motion, in arc strip from
Heart block under the influence of centrifugal force to arc strip outside move, centrifugal-block in moving process when centrifugal-block is contacted with drum
When, centrifugal-block can rub with drum, and centrifugal-block departs from arc strip at this time, but can be taken off with the increase arc strip of speed
From fixed reel, arc strip in centrifugal-block with closing;Arc strip drives drum to rotate by the friction of centrifugal-block and drum, drum
Rotation drives the rotation of Z-type wheel;The rotation of Z-type wheel is moved the first sun gear by the first unidirectional annulus and is rotated, the first sun gear rotation band
Dynamic first planetary gear rotation;First planetary gear drives ring gear rotation;Ring gear drives output shaft rotation;Due to arc strip at this time
Fixed reel is had been detached from, so arc strip will not drive fixing axle disc spins;That is input shaft rotation can drive output shaft to turn
It is dynamic.
