Equivalent pitch radius equals back cone distance Bevel gear 4. A face gear has a planar pitch surface and a planar root surface, both of which are perpendicular to the axis of rotation, see figure For a constant velocity ratio, the pitch cylinders and pitch cones are circular, see figures 25 and Bevel gears that operate on non–intersecting axes are known as hypoid gears, see 4.
A spiral bevel gear and pinion are always of opposite hand, including the case when the gear is internal. Roll path length is an alternative to roll angle for specification of selected diameter positions on an involute profile. See figures 53 and It is the responsibility of the gear designer to assure that the helix evaluation range is adequate for the application.
Where equations require a different format or constant for use with SI units, the primary equation has an M appended and the secondary expression is shown after the first, indented. Minus material beyond the start of tip break can be disregarded, see figure This is also referred to as the start of active profile, the start of contact, the end of contact, or the end of active profile, see figures 93 and It is the axis to which the gear details, and in particular the pitch, profile, and helix tolerances are defined.
Examples of such sections are the transverse section of bevel gear teeth and the normal section of helical teeth, see figure Also known as globoidal wormgearing. Please re-enter recipient e-mail address es. The name field is required.
Such measurements may be converted to corresponding values on transverse pitch circles for general comparisons.
AGMA technical publications are subject to constant improvement, revision, or withdrawal as dictated by experience. This standard is not included in any packages. 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. Cancel Forgot your password? Dedendum angle in a bevel gear, is the angle between elements of the root cone and pitch cone, see figure Please first log in with a verified email before subscribing to alerts.
Figure 42 — Crowned gear Profile angle Pressure angle Cutting tool Profile angle Standard profile angles are established in connection with standard proportions of gear teeth and standard gear cutting tools. Unless otherwise specified, the term spiral angle is understood to be the mean spiral angle, see figures 69 and When not specified, it is an unmodified involute.
In a helical gear it may be considered as the length of arc along a normal helix, see figure Many terms aagma listed in the index more than once by restating alphabetically with rearranged key words, to aid user look–up of related terms. Cylindrical worm Helical gear Helical rack Figure 7 — Helical gear and rack 4.

In a helical rack, a normal plane is normal to all the teeth it intersects. Advanced Search Find a Library. Spur gear Bevel gear Plane of rotation Important positions of a normal plane in tooth measurement and tool design of helical teeth and worm threads are: In gearing of other types, axial pitch may be confined to the pitch surface and may be a circular measurement, see figures 49 and Where there is no gap, they are known v05 herringbone, see figure 8.
Standards Subsctiption may be the perfect solution. In a helical gear, however, a plane can be normal to only one tooth at a point lying in the plane surface. Need more than one copy? Back cone distance in a bevel gear is the distance along an element of the back cone from its apex to the pitch cone, see figure It is usually cut by a tool that is geometrically similar to the worm.
Because of the widespread acceptance of the previous standards, changes were kept to a minimum. If the document is revised or amended, you will be notified by email. Preferably, these same surfaces should be used for manufacturing and inspection operations.

For double helical, it does not include the gap. Allow this favorite library to be seen by others Keep this favorite library private. Figure 98 — Schematic of pitch measurement, two probe device 5. The pitch plane of a pair agmma gears is the plane perpendicular to the axial plane and tangent to the pitch surfaces. At the time of publication, the editions were valid. Home About Help Search.

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