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. This project, gives the detail summary of the material selection, its load transmission, design of crown gear of differential, selection of different loads to clarify certain design factors and comparison between considered material which offers better results. For the material change approach, steel grade SAE 9310 is analyzed and compared with other material in terms of strength, mechanical properties, torque increment, processing, cost, etc. Strengths and strain are calculated theoretically and also with (ANSYS 16.0) analytical tool by tolerating loads on materials. 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.
