Abstract—Bevel gears are widely used because of their suitability towards transferring power between nonparallel shafts at almost any angle or speed. Spiral bevel gears, in comparison to straight or zerol bevel gears, have additional overlapping tooth action which creates a smoother gear mesh. This smooth transmission of power along the gear teeth helps to reduce noise and vibration that increases exponentially at higher speeds. Currently the bolero pickup vehicle of Mahindra Company is running with a pinion present in the differential gear box having 11 numbers of teeth. By reducing number of teeth on pinion, we can increase the torque. So we carried out this work to design a new pinion suitable to fit in the bolero pickup vehicle. Only the number of teeth are reduced by keeping all other dimensions same to fit the new pinion in the same housing.
