SSH ISO 6336-5:2003

Calculation of load capacity of spur and helical gears — Part 5: Strength and quality of materials

Scope

ISO 6336-5:2003 describes contact and tooth-root stresses, and gives numerical values for both limit stress numbers. It specifies requirements for material quality and heat treatment and comments on their influences on both limit stress numbers. Values in accordance with it are suitable for use with the calculation procedures provided in ISO 6336-2 and ISO 6336-3 and in the application standards for industrial, high speed and marine gears. They are also suited to the calculation procedures given in ISO 10300 for rating the load capacity of bevel gears. It is applicable to all gearing, basic rack profiles, profile dimensions, design, etc., covered by those standards. The results are in good agreement with other methods for the range indicated in the scope of ISO 6336-1.
