We need a reduction gearbox worm-gear with transmission ratio of 12:1 and output power of 100KW. Input shaft speed is 1200 rpm. The power is transmitted to input shaft using a coupling, and using another coupling transmitted to output shaft. The gear is made of phosphor bronze casting and worm is made of hardened steel. The material of gear shaft is Carbon steel with % 0.3 carbon. Design the gearbox in a way which efficiency is at least %85 and for permanent life. a. Design suitable worm and gear b. Design suitable shaft for both worm and gear c. Find loading on each bearing and find suitable ball/roller/tapered bearing (you suggest which bearing is good) d. Find the key size between shaft and gear (key material is carbon steel with % 0.2 carbon) Gear worm
