ActiveCalculation of load capacity of spur and helical gears—Part 4: Calculation of tooth flank fracture load capacity
直齿轮和斜齿轮承载能力计算 第4部分：齿面断裂承载能力计算
Application Summary AI generated
This standard specifies the calculation method for determining the load capacity of tooth flank fracture in spur and helical gears. It is applied in the design and verification of gear transmissions within mechanical systems, such as automotive drivetrains, industrial gearboxes, and heavy machinery, where high contact stresses can lead to subsurface fatigue failure. The standard provides engineers with a technical basis for evaluating gear durability and ensuring reliable performance under demanding operational conditions.
