An example of how to establish an AGMA classification number for a given set of conditions is presented in figure 5. The manufacturing of gearing to a specified accuracy may or 2015-1-s01 not include specific measurements. Specific requirements are to be stated in the contractual documents.

It is not a design manual for determining the specific quality levels for a given application. In such cases, it is possible to modify the accuracy grade to include an accuracy grade for each gear element or composite tolerance. For gear metrology purposes, a low–pass filter is usually applied to remove the influences of high frequency surface finish conditions from the observations of total, form, and slope deviations of involute and helix. Subscription pricing is determined 2105-1-a01 See clauses 6 and 7.

In this standard, lower AGMA accuracy grades designate higher precision in order to be consistent with international standards. When applications warrant, detailed specific measurements, data analysis, and additional considerations may be necessary to establish acceptance criteria for a gear. When applications require measurements beyond those 2015-1-01 in this standard, special measurement methods must be negotiated prior to manufacturing agm gear.

See Annex D for additional information. This standard specifies the direction of tolerancing for helix deviation to be in a transverse plane, on a line tangent to the base circle.

Please first verify your email before subscribing to alerts. Minus material beyond the tip break may be ignored. Consultant Profile Engineering, Inc. Slope and form errors are now included—In addition to total helix and profile errors, slope and form error are included for both profile and helix inspection.

Values of the next higher or lower grade are determined by multiplying or dividing by? Add to Alert PDF. If improved performance is desired, modifications of material, heat treatment, and accuracy level should be considered.

A New Standard in Gear Inspection

These considerations may include items such as: In some amga, the loaded side may 201-51-a01 higher accuracy than the nonloaded or minimum-loaded side; if applicable, this information is to be specified on the gear engineering drawing see 4. The other type employs Gaussian mathematics. Gear design is beyond the scope of this part of ISO This standard specifies the direction of tolerancing for profile deviation to be in a transverse plane, on a line tangent to the base circle.

Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. Documentation may be deemed agna for products manufactured under process control when inspection records are not specified in the purchase contract.

A filter that excludes long wavelength low frequency data is called a high–pass filter. It is defined by specification of datum surfaces. The datum axis determines tooth geometry, thereby being the reference for measurements and associated tolerances.

Log into your account. They may be submitted to tech agma. The design, accuracy, and cost of a master gear must be negotiated between the manufacturer and purchaser. Ten accuracy grades are defined in this standard, numbered A2 through A11, in order of decreasing precision. Measurements made in the normal direction coincide with this direction of tooth meshing motion. Some of the symbols and terminology contained in this document may differ from those used in other documents and AGMA standards.


Gear design is beyond the scope of this standard. Measurements at any other inclination will be larger. A general comparison between the new system and AGMA A88 systems may be made by subtracting the class or grade number of one system from 17 to find an approximate class or grade number for the other system. Master gears of grade 3 are recommended for checking gears primarily of grade 6 and 7. In applications that require inclusion of this very high frequency data, smaller probe tip radii can be specified.

An example of the formula to calculate total profile tolerance is shown in figure 6. It is developed by subtracting the ordinates of a straight–line gradient from the ordinates of the design helix. For undated references, the latest edition of the referenced document including any amendments applies. Future of gear design relies on overcoming present July 15, Please first log in with a verified email before subscribing to alerts. A master gear is a gear of known accuracy, designed specifically to mesh with the gear to be inspected for composite variation.

Columbia Gear Corporation W. An example of the differences between these analysis methods is provided by figure E.
