Design and fabrication of shaft drive mechanism for smooth and efficient transmission of power from pedals to rear wheel of a bicycle
(UMT Lahore, 2021-08) Haider Ali; Arham Awan; Mirza Tahir
Bicycles have been a pollutant free source of locomotion since a long period of time. Using human energy and converting it into torque for the movement. Chain drives have been pretty common in bicycles and have overruled all other drive mechanisms. The adherence to one system can be non-evolutionary from a perspective. A new power transmission mechanism has been studied which can be proved to be more efficient than a traditional chain drive system. A Shaft driven chainless system is discussed in this report, which completely replaces all the working elements of a traditional bicycle. The system has been analyzed numerically and theoretically. Using SOLIDWORKS a new gear and pinion mechanism has been designed according to the machining resources available and studied analytically using ANSYS. Experimentation has been performed which concludes that the proposed system can be very efficient.
