Cylindrical Wormgearing Tolerance and Inspection Methods<\/span><\/strong><\/span><\/p>\n

SCOPE<\/strong><\/u>
\n
This standard establishes a classification system which may be used to communicate geometrical accuracy specifications of unassembled cylindrical wormgearing with axes at right angles. \u00a0It also provides information on measuring methods and practices. \u00a0This standard provides the gear manufacturer and the gear purchaser with a mutually advantageous reference for uniform tolerances and inspection procedures. \u00a0Tolerance grades 3 through 12 are defined in this standard and are based on the relative effect of geometrical errors on conjugate action for wormgear sets acting as speed reducers.<\/p>\n

<\/span><\/p>\n

TOLERANCE EQUATION AND TABLES<\/strong><\/u>
\n
Tolerance equations are provided in clause 5 for calculating the maximum values allowed by the specific tolerance grade. \u00a0Tables are provided in annex A for reference.<\/p>\n

<\/span><\/p>\n

MEASURING METHODS AND PRACTICES<\/strong><\/u>
\n
Measuring methods and practices are included in order to promote uniform inspection procedures (see clause 4).\u00a0 These methods permit the manufacturer and purchaser to conduct measuring procedures which are accurate and repeatable to a degree compatible with the specified tolerance grade.<\/p>\n

<\/span><\/p>\n

EXCEPTIONS<\/strong><\/u>
\n
This standard applies to individual worm and gear components.\u00a0 It does not establish a tolerance grade for enclosed drive assemblies.\u00a0 Establishing ratings based on tolerance grade is beyond the scope of this standard.\u00a0 Gear design and backlash are also beyond the scope of this standard.\u00a0 Refer to the latest AGMA Publications Catalog for applicable standards.\u00a0 This standard does not apply to worms with mean diameters larger than 16 inches, nor does it apply to wormgears with mean diameters larger than 100 inches.\u00a0 This standard does not apply to geometry finer than 0.063 axial pitch.\u00a0 This standard does not apply to spiral gears or any type other than cylindrical single enveloping wormgearing.<\/p>\n

FOREWORD<\/strong><\/u>
\n
[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 ANSI\/AGMA 2011-B14, Cylindrical Wormgearing Tolerance and Inspection Methods<\/em>.]<\/span><\/p>\n

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.<\/span><\/p>\n

AGMA 390.02 September 1964 was a replacement for AGMA 234.01 for fine pitch wormgearing.\u00a0 ANSI\/AGMA 2000-A88 is a partial revision of AGMA 390.03, but does not cover wormgearing.\u00a0 AGMA 390.03a of 1988 still only covered fine pitch wormgearing.\u00a0 ANSI\/AGMA 2011-A98 then is a replacement for AGMA 390.03a for fine pitch wormgearing.\u00a0 In addition, it also covers coarse pitch wormgearing.<\/span><\/p>\n

The Cylindrical Wormgearing Committee began working on ANSI\/AGMA 2011-A98 in August, 1993.\u00a0 At that time, it was determined the International Standards Organization\u2019s (ISO) method for tolerance grades would be used in this standard.<\/span><\/p>\n

ANSI\/AGMA 2011-A98 was approved by the AGMA membership in June, 1998 and approved as an American National standard on October 1, 1998.<\/span><\/p>\n

The new ANSI\/AGMA 2011-B14 was required to correct a typographical error found in equation 18 of ANSI\/AGMA 2011-A98.\u00a0 The metric edition of the standard was not affected.<\/span><\/p>\n

The first draft of ANSI\/AGMA 2011-B14 was created in May 2013.\u00a0 It was approved by the membership in June 2014 and as an American National Standard on October 3, 2014.<\/span><\/p>\n
