Design of Propeller Shaft for Pedalling a Bicycle

The people those who are staying in developing countries like India depends on bicycles for transportation due to their financial status. My paper shows a better way to save their energy while pedalling bicycle also the design provides economical and user friendly. Actually chain drive and sprockets causes reduction power loss during Transmission⁵ of power from major fir- wheel² to rear wheel. The bevel gears are used to rotate the shaft in 900 angles. The back wheel of the bicycle is connected with the Bevel gear¹. Thus the back wheel is rotated in perpendicular to the major fir-wheel. Thus the two wheeler will move forward. According to the direction of motion³ of the bicycle, the wheel will be moved forward or reverse. A long rod, set of bevel gears and a bicycle is used for this construction. Overall construction is very cheap and does not get wear and tear as the chain and sprocket⁴ mechanism. The material used for this assembly is mild steel. This is obtainable everywhere in the country. The present design calculations suitable to local available bicycles.
