1. A bevel differential gear mechanism comprising:
first and second side bevel gears that are co-axially aligned along an axis of rotation; and an array of pinion bevel gears mounted between the first and second side bevel gears, the array of pinion bevel gears including a total number of pinion bevel gears, the pinion bevel gears intermeshing with the first and second side bevel gears to form a torque transfer arrangement configured for transferring torque between the pinion bevel gears and the first and second side bevel gears and for allowing the first and second side bevel gears to rotate at different rotational speeds with respect to one another, each of the pinion bevel gears having an actual gear face angle value that is at least 90 percent of a target gear face angle value, the target gear face angle value being equal to 360 degrees divided by twice the total number of pinion bevel gears, wherein the array of pinion bevel gears includes at least six pinion bevel gears, wherein each of the pinion bevel gears has an actual outside diameter value that is at least 80 percent of a target outside diameter value, wherein each of the pinion bevel gears has a spherical radius, and wherein the target outside diameter value for each of the pinion bevel gears is equal to 2 times the spherical radius multiplied by sine of the target gear face angle value. |
