Differential is an essential component of transmission system. The differential is designed to drive a pair of wheels with equal torque while allowing them to rotate at different speeds. For achieving different speed, gear train of differential must be designed in such a way that gears must transmit different speeds with efficient torque. In this project, regular metal used for gear is replaced by upgraded material to reduce vibrations and increase torque. In this project work, bevel pinion and crown gear present in the differential assembly is redesigned. The selected crown gear is the existing part of the SAFARI, the passenger car. In this project the crown and pinion material is replaced by upgraded material with more strength and durability of the gear set. Bevel pinion and crown gear are High efficiency gears (98 and higher) which can transfer power across non-intersecting shafts. Spiral bevel gears transmit loads evenly and are easy going than straight bevel.Here, Crown Gear is designed and analyzed for different speeds at 1200 rpm, 2000 rpm and 4000 rpm. Analysis is also conducted by varying the materials for gears SAE 9310, AISI 4310 and Aluminum Alloy. Further, the analysis is conducted to verify the best material for the crown gear in the gear box at higher speeds by analyzing stress, displacement and also by considering weight reduction. Analysis is done on the differential by applying tangential and static loads. After detailed analysis it is found that the performance of the Crown Gear by using Steel Grade SAE 9310 is appropriate, which results in decreasing vibration and wear.
