Calculation of load capacity of spur and helical gears - Basic principles, introduction and general influence factorsWhat is ISO 63361 Calculation of load capacity of spur and helical gears about? The formulae in the ISO 6336 series are intended to establish a uniformly acceptable method for calculating the load capacity of cylindrical gears with straight or helical involute teeth. ISO 63361 is the first part of the multi series that is applicable to the calculation of load capacity of spur and helical gears. The main objective of ISO 63361 is to minimize gear
