In this thesis, a transmission system of a roll forming machine is designed and optimized using planetary gears. The roll forming machine considered is owned by a company based in Chakan, Pune. A nascent company in the market,“BSS Anuj PVT. LTD.” was facing difficulties with a roll forming machine. Out of various the problems, one was of the failing transmission system. Reaching out to the company and gaining their consent, we embarked upon the project of redesigning the transmission system of that machine for the company. The project involves the design of a planetary gearbox and selection of suitable chain drives, replacing the old and conventional transmission system of worm gear boxes.
