It gives an approximate value for the factor by which the load on gear set can be increased while maintaining safety factor equal to 1 (Table 4.. 4.2.6.2 Integral Temperature Method for Non-offset Bevel Gears Integral temperature intThis temperature consists of the bulk temperature and the weighted mean tooth ank temperature aint. The mean ank temperature aintis in turn calculated from the ash temperature at the pinion tip without load sharing aE, and is converted to mean ank temperature using the contact ratio factor .
