ANSI/AGMA 2111-A98 (R2015)
Cylindrical Wormgearing Tolerance and Inspection Methods (Metric)
The purpose of this standard is to establish geometrical accuracy communication between a manufacturer and purchaser of unassembled cylindrical wormgearing with axes at right angles. AGMA 390.02 September 1964 was a replacement for AGMA 234.01 for fine pitch wormgearing. ANSI/AGMA 2000-A88 is a partial revision of AGMA 390.03, but does not cover wormgearing. AGMA 390.03a of 1988 still only covered fine pitch wormgearing. ANSI/AGMA 2111-A98 then is a replacement for AGMA 390.03a for fine pitch wormgearing. In addition, it also covers coarse pitch wormgearing. The Cylindrical Wormgearing Committee began working on this standard in August, 1993. At that time, it was determined the International Standards Organization’s (ISO) method for tolerance grades would be used in this standard. ANSI/AGMA 2111-A98 was approved by the AGMA membership in June, 1998 and approved as an American National standard on October 1, 1998.
