Abstract
The utility model provides a planetary speed increaser for bicycle, comprising a fixing inner gear, a planetary gear, a planetary gear rack, a planetary gear rack revolving axle, a centric gear sleeve and a chain wheel. Wherein, the planetary gear rack revolving axle passes through the inner hole of the centric gear sleeve; and the outer circle end of the centric gear sleeve is provided with a tooth, while the other end which is engaged with the planetary gear is provided with the chain wheel. When the planetary gear rotates initiatively, the centric gear sleeve and the chain wheel which is arranged on the centric gear sleeve are driven to rotate; and the chain wheel transfers the power to the fly wheel so as to drive the bicycle to run fast.
Description
The utility model relates to a kind of bicycle, specifically, relates to a kind of planetary speed increaser that is used for bicycle.
In known planet circular system, the speed increasing mechanism of being made up of fixing internally toothed annulus, the satellite gear of active transport, the sun wheel of driven running has been applied to some aspects.And the planet circular system that is used for bicycle at present is the internal speed-changing rear axle that is used in variable speed bicycle, is made up of planetary wheel, planet wheel seat, inner gear, sun gear, center shaft, flywheel sheet, left and right sides ratchet and speed setting controller.During work, do the thrust interlock under the control of governor, actuating force is reached the speed change parts, purpose is to change speed ratio, the conversion speed of a motor vehicle.Shaft transmission is a direct mount in the chain wheel of rickshaw on axis in patent No. ZL96214520.3 by name planetary, form by shifting cam, left and right sides flywheel, sun wheel, planetary wheel, internally toothed annulus, shifting cam is installed on the axis, in succession left and right sides flywheel, sun wheel is fixed on the axis spider, sun wheel overcoat satellite gear and internally toothed annulus, overriding clutch is arranged on the internally toothed annulus, handle shifting cam and overriding clutch and can reach the speed change purpose.This patent does not become commodity as yet and widely utilizes.
It is a kind of simple in structure that the purpose of this utility model is to provide, the planetary speed increaser that is used for bicycle of control comfort, and it can make bicycle move ahead fast.
The purpose of this utility model is achieved in that internally toothed annulus is fixed on the car body at bicycle middle part, sun gear and the wheel shaft that supports it are become the sun gear sleeve of one, the turning cylinder of planetary gear bearing frame can pass the sun gear sleeve in the hole, outside face one end of sun gear sleeve has tooth and planetary wheel engagement, and an end is equipped with sprocket wheel and connects with the flywheel of bicycle by chain.
When the turning cylinder of rotating support planetary wheel carrier, planetary wheel carrier and planetary wheel just rotate, and drive sun gear sleeve and sprocket wheel twirl, thereby bicycle is moved ahead fast.
The utility model cooperates them with assembling with other part commonly used of planet circular system because only need to make a sun gear sleeve and the rotating shaft that can pass the supporting pinion carrier of sun gear sleeve, so simple in structure, volume is little, and the rotation quick ratio is big; Simultaneously because the speedup effect of planet circular system, be installed in the outer sprocket wheel of sun gear sleeve and can do little, thereby laborsaving to pedal.
Concrete structure of the present utility model is drawn by following embodiment and accompanying drawing thereof.
Fig. 1 is the section-drawing according to the planetary speed increaser that is used for bicycle that the utility model proposes.
Describe details and service condition in detail below in conjunction with Fig. 1 according to the speed increaser that the utility model proposes.
This speed increaser is made up of rotating shaft (1), key pin (2), planetary gear carrier (4), little axle (3), bearing (5), internally toothed annulus (6), planetary wheel (7), housing (8), bearing (9), sun gear sleeve (10), sprocket wheel (11) key (12) of planetary gear bearing frame.
When rotating shaft (1) is rotated, planetary gear carrier (4) rotates, at this moment, because of planetary wheel (7) both meshed with fixed annulus (6), mesh with sun gear sleeve (10) again, so its one side is rotated around little axle (3), one side drives sun gear sleeve (10) and rotates, because the outside face of sun gear sleeve (10) is quiet again sprocket wheel (11) is installed, so sprocket wheel (11) also rotates simultaneously, and transmit power to flywheel and back rim by chain, bicycle is moved ahead fast.
Claims (1)
- A kind of planetary speed increaser that is used for bicycle, include planetary wheel (7), planetary gear carrier (4), internally toothed annulus (6) and sun gear, it is characterized in that this sun gear changed system into a sun gear sleeve (10), an end has tooth and planetary wheel (7) engagement on the cylindrical of sun gear sleeve (10), one end has keyway connecting sprocket wheel (11) with key (12), bearing (5) and axle (1) are housed in its endoporus, axle (1) is gone up and is being fixed planetary gear carrier (4) with key pin (2), sun gear sleeve (10) is installed on the housing (8) by bearing (9), turning cylinder (1) can drive sun gear sleeve (10) and on sprocket wheel (11) twirl, reach the speedup purpose.
