Full title and description

PD 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 example calculations demonstrating the application of the approximation methods and the calculation procedures given in the referenced parts of ISO 6336 to aid correct use of the standard series.

Abstract

This technical report presents worked examples that apply the approximation methods for determining influential factors used in ISO 6336 (for example the dynamic factor Kv and the load distribution factors KHα, KHβ). The examples illustrate the application of the calculation procedures of ISO 6336‑1, ISO 6336‑2, ISO 6336‑3 and ISO 6336‑5 and are intended for guidance only; they do not introduce recommended design values for real gearing and do not cover the more advanced analysis techniques.

Scope

Provides calculation examples to demonstrate the application of ISO 6336 parts 1, 2, 3 and 5 using the approximation methods described in those parts. The examples show how to calculate factors and carry out sample strength checks for spur and helical gears; they are intended as guidance for applying the standard procedures and are not a source of prescriptive design values or advanced-analysis cases.

Key topics and requirements

• Worked calculation examples applying ISO 6336 parts 1, 2, 3 and 5.
• Demonstration of approximation methods for specific influential factors (for example Kv, KHα, KHβ).
• Step‑by‑step sample calculations for flank and root strength assessments following ISO 6336 procedures.
• Guidance-only data: example numbers and safety factors are illustrative and not to be used as mandatory design limits.
• Excludes advanced analytical methods and complex numerical examples — focuses on standard approximation approaches.

Typical use and users

Intended for gear designers, mechanical engineers, standards implementers, verification engineers and educators who apply the ISO 6336 calculation procedures. Useful as a training and reference aid when learning how to perform strength and load‑capacity calculations for spur and helical gears in accordance with the ISO 6336 series.

Related standards
