This information sheet provides information for the application of bevel and hypoid gears using the geometry in ANSI/AGMA ISO 23509, the capacity as determined by ISO 10300 (all parts), or ANSI/AGMA 2003-C10 and AGMA 932-A05, and the tolerances in ANSI/AGMA ISO 17485.
This information sheet provides additional information on the application, manufacturing, strength and efficiency of bevel gears for consideration in the design stage of a new bevel gear set.
The term "bevel gear” is used to mean straight, spiral, zerol bevel and hypoid gear designs. Where this information sheet pertains to one or more, but not all, 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.
This information sheet is intended for use by an experienced gear designer capable of selecting reasonable values for the required data based on his/her knowledge and background. It is not intended for use by the engineering public at large.
[The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of AGMA ISO 22849-A12, Design Recommendations for Bevel Gears.]
The U.S. delegation proposed development of a new standard to ISO Technical Committee 60 on bevel gear geometry and associated design recommendations based on ANSI/AGMA 2005-D03, Design Manual for Bevel Gears. It was decided to address this project through the preparation of 1) an International Standard focusing strictly on bevel geometry (ISO 23509:2006, Bevel and hypoid gear geometry), and 2) a complimentary ISO Technical Report (ISO/TR 22849:2011, Design recommendations for bevel gears) which would present other design issues to be considered.
ISO 23509 was adopted as an American National Standard, ANSI/AGMA ISO 23509-A08, in 2008.
Information Sheet AGMA ISO 22849-A12 represents an identical adoption of ISO/TR 22849:2011 with the following revisions/clarifications:
The first draft of AGMA ISO 22849-A12 was made in May, 2011. It was approved by the AGMA membership on May 7, 2012.
Suggestions for improvement of this document will be welcome. They should be sent to the American Gear Manufacturers Association, 1001 N. Fairfax Street, Suite 500, Alexandria, Virginia 22314.
