Calculation of load capacity of spur and helical gears - Part 6 : calculation of service life under variable load

ISO 6336-6:2006 specifies the information and standardized conditions necessary for the calculation of the service life (or safety factors for a required life) of gears subject to variable loading. While the method is presented in the context of ISO 6336 and calculation of the load capacity of spur and helical gears, it is equally applicable to other types of gear stress.

Cylindrical gears. Calculation of service life under variable load. Conditions for cylindrical gears in accordance with ISO 6336.

Le présent document définit la méthode de calcul de la durée de vie en service d'engrenages cylindriques soumis à des charges variables, conformément aux normes ISO 6336, parties 1 à 3 et 5, relatives au calcul de la capacité de charge des engrenages cylindriques à denture droite et hélicoïdale. Cette méthode de calcul peut être appliquée à d'autres méthodes de calcul de dimensionnement, telles que celle décrite dans la norme expérimentale E 23-015 de juillet 1982, dont la révision est en cours.

Calculation of load capacity of spur and helical gears - Part 6 : calculation of service life under variable load

This document specifies the information and standardized conditions necessary for the calculation of the service life (or safety factors for a required life) of gears subject to variable loading for only pitting and tooth root bending strength. If this scope does not apply, refer ISO 6336-1:2019, Clause 4.

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!
