The test radius limits define the allowable range of test radii that takes into account tooth thickness and total composite variations.

Please verify that you are not a robot. The base circle is tangent to straight line extensions of the worm tooth profiles in the central plane of the wormgear. The designations, right hand and left hand, are the same as in the long established practice for screw threads, both external and internal.

It is properly the radius of curvature of the pitch surface in the given cross section. It included some symbols and abbreviations. In a spiral bevel gear, unless otherwise specified, profile angle means normal profile angle at the mean cone distance.

Gear nomenclature, definitions of terms with symbols : AGMA standard.

As actually indicated by measuring devices, backlash may be determined variously in the transverse, normal, or axial planes, and either in the direction of the pitch circles, or on the line of action. Within the evaluation range the straight–line gradient is found by applying the least squares method to the deviation of the measured helix trace from the specified design helix.


Figure 2 — Worm 4. It is a dimension measured along a line or curve in the transverse, normal, or axial directions. An internal helical gear and its pinion must be of the same hand. Substantial agreement means much more than a simple majority, but not necessarily unanimity. The profile specified by the designer as shown on the design specification. With undercut agmx fillet curve intersects the working profile.


Also known as globoidal wormgearing. When not otherwise specified, the short term cone distance is understood to be outer cone distance, see figure Already Subscribed to this document. Equivalent pitch radius equals back cone distance Bevel gear 4. Cylindrical pitch surfaces Figure 23 — Central plane 4. No part of this publication may be reproduced in any form, in an electronic retrieval system or otherwise, without prior written permission of the publisher.

The reference surface may be the reference axis of t05 gear, a datum surface or either one or two pins positioned in the tooth space or spaces opposite the first.

This standard establishes the definitions of terms, symbols and abbreviations which may be used to communicate the technology and specifications of external and internal gear teeth.

Purpose This annex is intended to be a reference for additional terms and symbols used within AGMA standards, where meaning is established by their usage and verbiage within the respective standards. 0g5

Standards Subsctiption may be the perfect solution. Add to Alert PDF. Bevel gears that operate on non–intersecting axes are known as hypoid gears, see 4. In addition, terms which started to be commonly used in gear load rating were introduced in the annex. They are characterized by a tapered depth and a tapered tooth thickness.

Right hand worm Left hand worm Figure 60 — Helical and worm hand 20 4. They have teeth of the same or different helix angles, of the same or opposite hand. Please first verify your email before subscribing to alerts.

As the voice of the U. This diameter cannot be less than the base circle diameter, see figure Mean cone distance 4. Face width Gap 4.

As the voice of the U. At the time of publication, the editions were valid. Already Subscribed to this document.


It applies to spur gears, parallel axis or crossed axis helical gears, and wormgearing, see figure As long as the measuring device has parallel measuring surfaces that contact on an unmodified portion of the involute, the measurement will be along a line tangent to the base cylinder.

Face width is the length of teeth sgma an axial plane, see figure In hypoid gear design, the pinion and gear are practically always of opposite hand, and the spiral angle of the pinion is usually larger than that of the 22 Spiral angle Figure 69 — Spiral angle 4. The beginning of wisdom is to call things by their right names. Front angle, in a bevel gear, is the angle between an element of the front cone and a plane of rotation, and usually equals the pitch angle, see figure They allow meshing in gg05 geometric configuration and with any conjugate mate, spur, helical, worm, rack, face, internal, etc.
