NOTE: THIS TECHNICAL SPECIFICATION REPLACES ISO/TR 13989-1.
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.
This document was prepared by Technical Committee ISO/TC 60, Gears, Subcommittee SC 2, Gear capacity calculation.
This first edition of ISO/TS 6336-20 cancels and replaces ISO/TR 13989-1.
A list of all parts in the ISO 6336 series can be found on the ISO website. See also the Introduction for an overview.
