Abstract
The utility model belongs to bicycle class, relates to a kind of Chainless bicycle planetary gear transmission device.In flower-drum one end, flywheel is set; Planet gear transmission system is arranged at flywheel outer end; Wheel shaft is connected by bearing with back vent; Wheel shaft two ends connecting crank; The sun wheel end of described planet gear transmission system connects wheel shaft by bearing; Sun wheel and flywheel are connected and fixed; Pinion carrier and the wheel shaft of planet gear transmission system are connected and fixed; Planet gear transmission system external toothing and back vent are connected and fixed.Use planet gear transmission system driving device to achieve Chainless bicycle and take turns driven off by shaft high transmission ratio.The utility model exports the revolution after transmitting ratio change by planet gear transmission system, is applied to flywheel and flower-drum, and band motor car wheel High Rotation Speed, makes Chainless bicycle improve riding speed, add practicality.
Description
Technical field
The utility model belongs to bicycle class, relates to a kind of Chainless bicycle planetary gear transmission device.
Background technology
Common Chainless bicycle, it takes turns shaft drying transmission ratio of revolution is 1:1, and namely pedal one encloses, and rotation of wheel one encloses, and riding speed is restricted.
Summary of the invention
The purpose of this utility model proposes a kind of Non-chain bicycle transmission mechanism that can realize high transmission ratio.Technical solution of the present utility model is: device comprises crank, wheel shaft, planet gear transmission system, flywheel, flower-drum, bearing.It is characterized in that: flower-drum one end arranges flywheel; Planet gear transmission system is arranged at flywheel outer end; Wheel shaft is connected by bearing with back vent; Wheel shaft two ends connecting crank; The sun wheel end of described planet gear transmission system connects wheel shaft by bearing; Sun wheel and flywheel are connected and fixed; Pinion carrier and the wheel shaft of planet gear transmission system are connected and fixed; Planet gear transmission system external toothing and back vent are connected and fixed.Pinion carrier is revolution input, and sun wheel is that revolution exports, and determines transmission ratios by the number of teeth of satellite gear, sun wheel and external toothing, forms certain driving system exporting input ratio of revolution.
The advantage that the utility model has and beneficial effect: the utility model exports the revolution after transmitting ratio change by planet gear transmission system, is applied to flywheel and flower-drum, band motor car wheel High Rotation Speed, makes Chainless bicycle improve riding speed, adds practicality.Use planet gear transmission system driving device to achieve Chainless bicycle and take turns driven off by shaft high transmission ratio.
Accompanying drawing explanation
Fig. 1 is drive mechanism generalized section of the present utility model;
Fig. 2 is the structural representation of the utility model planet gear transmission system;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is the birds-eye view of Fig. 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Being embodied as of Chainless bicycle planetary gear transmission device: crank 8 connects wheel shaft 1; Wheel shaft 1 is connected and fixed with the pinion carrier 13 of planet gear transmission system 4; Sun wheel 10 one end in planet gear transmission system 4 is connected and fixed with flywheel 2 of living, and sun wheel 10 is connected by bearing 5 with wheel shaft 1; Flywheel 2 is twisted solid on flower-drum 9; Back vent 3 is connected with wheel shaft 1 by bearing 7; External toothing 12 and the back vent 3 of planet gear transmission system 4 are connected and fixed by securing arrangement 6.Driving is input as pinion carrier 13, exports as sun wheel 10.
In the course of the work, foot-operated connecting crank 8 Forced rotation, drive wheel shaft 1, wheel shaft 1 drives the pinion carrier 13 in planet gear transmission system 4 to rotate; Pinion carrier 13 drives three satellite gears 11 to rotate, and satellite gear 11 drives sun wheel 10 to rotate, and rotating speed after sun wheel 10 exports and accelerates, is transferred to the flywheel alive 2 that it connects, and flywheel 2 of living drives flower-drum 9 that wheel is advanced.
