Design and Optimization of Helical Gear Box

Gears are the main access for the automobile industries. Gears are usually used to transmit the power between the shafts. During the sudden variation in load, it can able to withstand the variation. Normally the Two wheeler gear box consists of spur gear and helical gear. During high speed rotation of Spur gear, produces noisy operation, increased engine temperature etc. It leads to decrease the engine efficiency and also reduce the gear box life. So to overcome the drawback wedesigned to replace spur gear to helical gear by varying the helix angle
