This document is equivalent to ISO /T R22849.2011 "Bevel Gear Design Recommendations". The document type is adjusted from ISO 's technical report to my country's National standardization guiding technical documents. This document adds two chapters. "Normative References" and "Terms and Definitions". This document has made the following minimal editorial changes. ---Correct the informative reference of ISO /T R13989-1 in 5.2.4 to ISO 10300-20; ---Corrected formula (3) and formula (4). The original ISO text mistakenly made the back cone bus and the top cone bus perpendicular, resulting in formula errors; ---Added Appendix NA (informative).

Bevel gear design suggestions1 ScopeThis document provides application information for bevel gears and hypoid gears regarding geometry, load carrying capacity, and accuracy tolerances, respectively. ISO 23509, ISO 10300 (all parts) and ISO 17485. This document provides relevant information on the application, manufacturing, strength and efficiency of bevel gears for designers' reference. The term "bevel gear" is used for the designs of straight bevel gears, spiral bevel gears, zero-degree bevel gears, and hypoid gears. If in this document The content only involves one or more (but not all) of the forms, and there will be special instructions. Note. Appendix NA gives the classification of bevel gears and various expressions of terminology. The target tooth profile described in this document can be processed by various methods and is universal and does not imply a specific process. This document is intended for experienced gear designers who can rely on their knowledge and background to make reasonable choices for the required values. This document is not intended for general technical personnel.2 Normative reference documentsThis document has no normative references.3 Terms and definitionsThere are no terms or definitions to be defined in this document. 4 Symbols, descriptions and units The symbols and descriptions used in this document have been harmonized as far as possible with other international standards for bevel gears. Due to certain limitations, there are Some symbols and descriptions of spur and helical gear transmissions differ from similar literature.
