Bevel and hypoid gear geometry

ISO 23509:2016 specifies the geometry of bevel gears. The term bevel gears is used to mean straight, spiral, zerol bevel and hypoid gear designs. If the text pertains to one or more, but not all, of these, the specific forms are identified. The manufacturing process of forming the desired tooth form is not intended to imply any specific process, but rather to be general in nature and applicable to all methods of manufacture. The geometry for the calculation of factors used in bevel gear rating, such as ISO 10300 (all parts), is also included. ISO 23509:2016 is intended for use by an experienced gear designer capable of selecting reasonable values for the factors based on his/her knowledge and background. It is not intended for use by the engineering public at large. Annex A provides a structure for the calculation of the methods provided in this document.

Bevel and hypoid gear geometry

Le présent document définit la géométrie des engrenages coniques droits, spiroconiques, coniques zérol et hypoïdes. Il définit également les paramètres nécessaires au calcul des dimensions de ces engrenages. Il présente trois méthodes de conception des engrenages coniques et une méthode spécifique pour les engrenages spiroconiques, qui s'appuient sur un ensemble complet de formules.

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.
