Calculation of scuffing load capacity of cylindrical, bevel and hypoid gears - Part 1 : flash temperature method

Le concept fondamental selon Blok est applicable à tous les éléments de machine ayant des zones de contact mobiles. Les formules de température-éclair sont valables pour une zone de contact hertzien en forme de bande ou quasiment en forme de bande et pour des conditions de fonctionnement caractérisées par des nombres de Péclet suffisamment élevés.

Calculation of load capacity of spur and helical gears - Part 20 : calculation of scuffing load capacity (also applicable to bevel and hypoid gears) - Flash temperature method

<p>ISO/TS 6336-20:2017 specifies methods and formulae for evaluating the risk of scuffing, based on Blok's contact temperature concept.</p> <p>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.</p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
