Dissertation Report of Slip-On Sprocket

This continuous research basically is to enhance and improve the idea of the ‘Ring Chain Sprocket’. This product was proven to increase the torque of the motorcycle without changing the original sprocket and modifying the engine. As for the previous research, the product is called Ring Chain Sprocket and two prototypes was produced which is Alpha and Beta I. Alpha prototype was produced by Thermojet 3D Printer and Beta I was produced by using CNC process and the material is steel. During this research, the name was changed to ‘Slip-On Sprocket’ and Alpha prototype was reprinted and Beta II was fabricated by Laminated 3D Printing. Beta I, which is steel are not suitable for initial mass fabrication because it is very expensive and the CNC process will take a long time. Other than that, silicon rubber moulding will not cost as much as using injection moulding and it is feasible for final year project. This project used the method of Silicon Rubber Moulding as the fabrication process and the product of silicon rubber moulding will be polyutherane resin but the desired product cannot produce because the material was expired. However, it is proven that silicone rubber moulding is easier, faster and cheaper than CNC and injection moulding. This project was carried out in the Rapid Prototyping lab in Block 16, Universiti Teknologi Petronas
