Full title and description

St ISO TR 6336-30:2022 — Calculation of load capacity of spur and helical gears — Part 30: Calculation examples for the application of ISO 6336 parts 1, 2, 3 and 5. This technical report provides worked calculation examples that illustrate the application of the approximation methods and specific influential factors used in ISO 6336 series standards.

Abstract

This technical report presents worked examples that apply exclusively the approximation methods for determining specific influential factors (for example the dynamic factor Kv and the load distribution factors KHα, KHβ). The examples are intended to guide the application of ISO 6336-1:2019, ISO 6336-2:2019, ISO 6336-3:2019 and ISO 6336-5:2016; they do not provide recommended design criteria for real gearing and do not cover advanced analytical procedures.

Scope

This technical report provides worked calculation examples to demonstrate how to apply the approximation methods described in ISO 6336 parts 1, 2, 3 and 5. It focuses on example calculations for commonly used approximation procedures (dynamic factor Kv, load distribution factors KHα and KHβ, etc.) and explicitly excludes worked examples of more advanced analytical techniques. The examples are for guidance only and do not by themselves constitute recommended design values.

Key topics and requirements

• Worked calculation examples illustrating application of ISO 6336 parts 1, 2, 3 and 5.
• Use and calculation of approximation methods for dynamic factor Kv.
• Determination and use of load distribution factors KHα (profile) and KHβ (helix/face load distribution).
• Step-by-step example workflows to apply the ISO 6336 calculation sequence.
• Clarification that examples are for guidance and not prescriptive design values.
• Reference to the analytical procedures contained in the primary ISO 6336 parts (where full analytical methods are specified).

Typical use and users

This report is intended for gear designers, mechanical engineers, gearbox manufacturers, testing and validation engineers, standards committees, and educators who need worked examples to support correct application of the ISO 6336 gear rating procedures. It is particularly useful when interpreting approximation factors and when training staff to apply ISO 6336 calculation steps consistently.
