Abstract
The invention provides a speed increasing and changing device of a planetary gear, which mainly comprises an internal gear (1), a planetary gear frame (2), a central wheel (3), an overrunning clutch (4) and the like, and is mainly applicable to the speed increasing and changing devices of small-wheel bicycles, electric bicycles and wind turbines; as long as the overrunning clutch (4) is arranged between the planetary gear frame (2) and the central wheel (3) for constituting a first-stage planet row, the 2-gear speed change can be obtained, two-stage planet rows can obtain 4-gear speed change, ten-stage planet rows can obtain 1024-gear speed change, and the planetary gear speed increasing and changing device can realize any-gear speed change by leading the speed ratio of each-stage planet row to be different. The speed increasing and changing device of the planetary gear has simple structure and stable working.
Description
Technical field
The present invention relates to a kind of planetary speed variator, definite saying relates to a kind of speed increasing and changing device of planetary gear.
Background technology
Existing planetary gear speed-changing is used all fine at field of traffic in some fields especially, can how to invent and all there is no out of this world technology at mechanical field, the mankind, enter 21 century in the flourishing epoch of information, also need more invention technology, the invention provides a kind of new invention technology, in needs, have many a kind of selections.
Summary of the invention
Object of the present invention provides a kind of small-wheel bicycle that makes equally quick to bull wheel cycling, uses this speed increasing and changing device of planetary gear on Electrical Bicycle, can make Electrical Bicycle improve travelled distance, also makes aerogenerator increase electric energy generated and degree of utilization.
Technical scheme of the present invention is a kind of speed increasing and changing device of planetary gear, and Fig. 1 includes inner gear, pinion carrier, center gear, the compositions such as overriding clutch.Fig. 2 includes inner gear, planetary gear carrier, and center gear, surmounts the compositions such as ratchet device.Fig. 1, though the structure of Fig. 2 is different, can control equally, is the same in input and output transmission.Just with Fig. 1 invention technical scheme, illustrate: describedly between planetary gear carrier and center gear, be provided with overriding clutch, as long as pin inner gear, just obtain increasing gear output, loosen inner gear and just obtain direct-drive, just so simple, variable 2 grades of one-level planet row, secondary planet is arranged variable 4 grades, variable 1024 grades of ten grades of planet rows, and how many grades of settings are on demand selected.
Accompanying drawing explanation
Fig. 1 is planetary wheel overrun clutch structure figure of the present invention.
Fig. 2 is that planetary wheel of the present invention surmounts ratchet device constructional drawing.
The specific embodiment
Technical scheme of the present invention comprises inner gear (1), planetary gear carrier (2), center gear (3), overriding clutch (4) or surmount the compositions such as ratchet device (4).Between planetary gear carrier (2) and center gear (3), be provided with overriding clutch (4) or surmount ratchet device (4) combination one-level planet row.
Once, be implemented in that one-level planet row is set on electrical bicycle middle shaft is much of that, because power consumption is maximum when the Electrical Bicycle speed of a motor vehicle is fast, at this moment pin inner gear (1) and can obtain shelves power-assisted speed of a motor vehicle minimizing power consumption soon, increase travelled distance, if Electrical Bicycle has not had electricity, Electrical Bicycle can also be worked as to derailleur and ride.
Two, be implemented in secondary planet row is also set on the axis of small-wheel bicycle, can obtain 4 grades of speed changes, the direct-drive of riding is at the beginning one grade, pin one-level planet row inner gear (1) and can obtain 2 grades of speed changes, pin in addition another grade of planet row inner gear (1) and can obtain the 3rd grade of speed change, pin two-stage planet row inner gear (1) simultaneously and can obtain 4 grades of speed changes, no matter need how many grades of speed changes, the speed ratio that every grade of planet row is set is just different.
Three, implement also can be arranged in wind power generating set, because aerogenerator need to be worked in constant speed, because the step-up gear that present wind power generating set is used is can not speed change ground, that speed governing by other means meets the requirement that electrical generator is worked in constant speed, but wind speed is continuous variation, sometimes suddenly big or suddenly small, can not meet the demands, as long as being used instead to planetary wheel of the present invention, former step-up gear increases speed-change gear box, its gear is many, range of speed is large, just can meet the job requirement of aerogenerator in constant speed, improve the degree of utilization of aerogenerator, this apparatus structure is simple, working stability.
Claims (3)
1. a speed increasing and changing device of planetary gear, include inner gear (1), planetary gear carrier (2), center gear (3), overriding clutch (4), it is characterized in that: between described planetary gear carrier (2) and center gear (3), be provided with overriding clutch (4), pin inner gear and can realize the output of increasing gear, loosen inner gear and can realize direct-drive.
2. speed increasing and changing device of planetary gear according to claim 1, is characterized in that: described overriding clutch is free-wheel clutch (4).
3. speed increasing and changing device of planetary gear according to claim 1, is characterized in that: described overriding clutch is ratchet device (4).
