BS ISO 6336-2:2019

This standard BS ISO 6336-2:2019 Calculation of load capacity of spur and helical gears is classified in these ICS categories:

• 21.200 Gears

This document specifies the fundamental formulae for use in the determination of the surface load capacity of cylindrical gears with involute external or internal teeth. It includes formulae for all influences on surface durability for which quantitative assessments can be made. It applies primarily to oil‑lubricated transmissions, but can also be used to obtain approximate values for (slow‑running) grease‑lubricated transmissions, as long as sufficient lubricant is present in the mesh at all times.

The given formulae are valid for cylindrical gears with tooth profiles in accordance with the basic rack standardized in ISO 53. They can also be used for teeth conjugate to other basic racks where the actual transverse contact ratio is less than ε_αn = 2,5. The results are in good agreement with other methods (see References [5], [7], [10], [12]).

These formulae cannot be directly applied for the assessment of types of gear tooth surface damage such as plastic yielding, scratching, scuffing and so on, other than that described in Clause 4.

The load capacity determined by way of the permissible contact stress is called the “surface load capacity” or “surface durability”.

If this scope does not apply, refer to ISO 6336‑1:2019, Clause 4.
