Provides guidance on the design, rating and manufacture of spur and helical gears for power transmission. It is based on Standards published by the American Gear Manufacturers Association.
rect for spur gears and for helical gears in the transverse section (the section perpendicular to the axis of the gear). Equation numbers with alphabetic modifiers are given for use in the numeric examples. Gears are a key component of motor and machinery actuators; they increase the output torque and control the direction of rotation or the speed.
