標準簡介
Describes a general application standard for spur and helical external and internal gears of accuracy grades 3 to 10 operating at any pitch line speed. The calculations given are not applicable to the prediction of gear damage caused by scuffing, wear, welding or fracture of the gear rims, web, or hub. Covers methods for determining the actual and permissible contact and bending stresses in a pair of involute gears. Stress levels on the tooth flank and in the tooth root are compared with basic permissible stress levels derived from simple test specimens.
