Abstract
The utility model relates to a crank wheel accelerator comprising a crank and a middle shaft which are fixedly connected; the middle shaft is hinged in a middle shaft support sleeve; the middle shaft support sleeve is fixedly connected with a fastening sleeve; the crank wheel accelerator is characterized in that a planetary carrier is fixed on one end of the middle shaft; at least two planetary wheels are hinged on the planetary carrier; the planetary wheels are mutually meshed with a central wheel which is fixedly connected onto the fastening sleeve and are mutually meshed with an inner gear of a large sprocket which is hinged on the fastening sleeve. On the premise of not changing the prior art that the large sprocket drives a small sprocket through a chain and the final stage of acceleration is realized through pulley cones with different diameters and gear quantity; because a planetary acceleration structure is adopted, the first stage of large sprocket can obtain acceleration ratio and the acceleration ratio is large, so that the crank wheel accelerator has a reasonable structure, can meet the needs of a rider, and is applicable to bicycles, tricycles, ships and the like which are driven by manpower.
Description
Technical field
The utility model relates to vehicle transmission gear, particularly is applicable to the driving device of manually driven bicycle, three-wheel vehicle and boats and ships etc., more particularly, is a kind of crank wheel speed increaser.
Background technology
The driving device of available man-power bicycle driven, three-wheel vehicle and boats and ships all is direct cranked hinge wheels of clamping band on the axis of frame, the hinge wheel that has a crank is connected by minor sprocket fixing on chain and the Power Available Shaft, the propulsive effort of the crank moment of couple is passed to hinge wheel, and hinge wheel turns a wheel by the chain drive minor sprocket.Usually transmitting ratio is constant, i.e. the ratio of the hinge wheel number of teeth and the minor sprocket number of teeth; Existing derailleur is to realize speed change by the diameter cone pulley different with the number of teeth.In sum, the driving speedup mode of prior art all is to realize at the final stage minor sprocket of driving device, exists unreasonable structure, to derailleur, especially for the sports tournament derailleur, even the highest existing speedup transmitting ratio does not still satisfy bicyclist's needs.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, just can obtain over-speed gear ratio at the chopped-off head hinge wheel of driving device, and the big crank wheel speed increaser of over-speed gear ratio.
The technical scheme that is adopted is for achieving the above object: a kind of crank wheel speed increaser, it comprises that crank and axis are connected, axis is articulated in the axis support sleeve, axis support sleeve and adapter sleeve are connected, it is characterized in that: at the fixing tangible star frame of an end of axis, be hinged with at least two shape star-wheels on shape star frame, described shape star-wheel is meshed with center gear on being connected in adapter sleeve and is meshed with the internal tooth of hinge wheel on being articulated in adapter sleeve.
Crank wheel speed increaser of the present utility model, do not change existing by hinge wheel by the chain drive minor sprocket, or on the basis by the diameter cone pulley realization final stage speedup different with the number of teeth, owing to adopted shape star speedup structure, make the chopped-off head hinge wheel just can obtain over-speed gear ratio, and over-speed gear ratio is big, has rational in infrastructure, can satisfy bicyclist's needs, can be suitable for manually driven bicycle, three-wheel vehicle and boats and ships etc. and go up use.
Description of drawings
Fig. 1 is a crank wheel speed increaser structural representation of the present utility model.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Among the figure: 1 crank, 2 hinge wheels, 3 shape star framves, 4 shape star-wheels, 5 little bearings, 6 bearings, 7 axis support sleeves, 8 backup bearings, 9 axis, 10 adapter sleeves, 11 center gears.
The specific embodiment
The utility model is described in further detail to utilize specific embodiment shown in the drawings below.
With reference to Fig. 1 and 2, the crank 1 and the axis 9 of crank wheel speed increaser of the present utility model are connected, axis 9 is loaded in the axis support sleeve 7 by backup bearing 8, axis support sleeve 7 is connected with adapter sleeve 10, at the fixing tangible star frame 3 of an end of axis 9, shape star frame 3 is equipped with at least two shape star-wheels 4 by little bearing 5, and described shape star-wheel 4 is meshed and is meshed with the internal tooth that is loaded on the hinge wheel 2 on the adapter sleeve 10 by bearing 6 with center gear 11 on being connected in adapter sleeve 10.
