Acknowledgement We would like to express our special thanks of gratitude to Dr T C Bera, who gave us the opportunity to do this project, which also helped us to get Hands-on experience of various Production Technique process
Secondly, we would like to thank the entire Workshop instructors who helped us a lot in finalizing this project within the limited time frame
Introduction The gym cycle as the name suggests is used for incorporating cycling as a physical exercise in the gym. The physical exercise gained from cycling is generally linked with increased health and well-being. It improves fitness and cardiovascular health.
The gym cycle converts muscular energy to kinetic energy. Cycling drives a heavy flywheel, generally with the help of a chain. The torque required to drive the flywheel can be varied with the help of a brake which increases the strain on the muscles and hence gradually enhances its strength.
ABSTRACT We aim to fabricate a self- styled functional gym cycle using the materials, instruments and machines present in our workshop. Here, in this abstract, we will describe in brief how we went about making this model.
The design of the model was done on Solid Works. The design involved taking into consideration material and fabrication facilities available in our workshop. The cycle was designed to suit the dimensions of the average male. After the design was approved, we began its fabrication.
Construction involved using a variety of machines and tools for creating the ideal size and shapes of all our individual parts.
Welding was used primarily for joining since steel has been extensively used because of the strength requirements. The lathe was used for turning of our pedal shaft to ensure that it just press-fits into the bearing. Shear cutter was used to cut mild steel sheets for the flywheel and the pedal. The finishing of these approximate cuts was done on band saw and then later on the grinding wheel We also used wood for our seat, pedals and the flywheel. Drilling was one of the most important processes in this project like in most other projects.
Various tools such as drill bits, chucks, turning tools, vernier calipers were used throughout our construction process.
The entire team thoroughly enjoyed this long, interesting and educational experience especially so since the project produced a working model as planned.
