This paper presents the development of the transfer case for a 3.5-ton commercial vehicle. A transfer caseis composed of many parts, including helical gear, shaft, bearing, planetary gear, and others. Helical gears arecurrently used as power transmitting gears due to their relatively smooth and silent operation, large loadcarrying capacity, and operation at higher speeds. The key parameter in transfer case development is thebending stress at the root of a tooth in the helical gear. The bending stress of the helical gear has beenstudied through theoretical calculation and finite element method (FEM) analysis. Major factors of the bendingstress calculation are determined according to American Gear Manufacturers Association (AGMA) standards,and FEM model analysis of the helical gear is conducted. FEM results are compared with theoreticalcalculations and the difference of the bending stress is described.
