Calculation of load capacity of spur and helical gears — Part 20: Calculation of scuffing load capacity — Flash temperature method

Calcul de la capacité de charge des engrenages cylindriques à dentures droite et hélicoïdale — Partie 20: Calcul de la capacité de charge au grippage — Méthode de la température-éclair

A new edition is under development: ISO/AWI 6336-20.

Abstract / scope

This document specifies methods and formulae for evaluating the risk of scuffing, based on Blok's contact temperature concept.

The fundamental concept is applicable to all machine elements with moving contact zones. The flash temperature formulae are valid for a band-shaped or approximately band-shaped Hertzian contact zone and working conditions characterized by sufficiently high Péclet numbers.
