We have no document history for this standard. With most inspection machines, the probe moves along the tooth parallel to the axis of the part. Line 1 represents the design helix, which in this case does not have any intentional modifications. Please first verify your email before subscribing to alerts. The same procedure is used to classify the quality level of the left flanks.
It is a complete revision in order to be more compatible with ISO. Heat Agja of Steel Gears July 15, Log into your account.

The accuracy grade numbering system has been reversed, so that the smallest number now represents the most accurate grade. Already Subscribed to this document. If the document is revised or amended, you will be notified by email. Converting to linear motion using rack and pinion. Line 2 represents the actual trace of the tooth and the deviation of the actual 951 from the nominal.
Site Safety October 1, Normally both flanks of three to four teeth equally spaced around the gear are measured and the results magnified and charted on a strip chart or printed out.
Tooth Tips: Gear Accuracy Charts Pt. 2
Provides a code of practice dealing with inspection relevant to tangential element and composite deviations of cylindrical involute gears measurements referred to single flank contact.
If the measured helix were perfect without any intentional modifications, the trace would be a straight line as shown at line 1 on the chart. See Figure 1 for an explanation of what they represent. This standard is not included in any packages. Please first log in with a verified email before subscribing to alerts. As the voice of the U. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. In addition to the actual helix traces, numerical values for the different helix parameters may be shown on the printed output.
Site Safety June 1, Subscription pricing is determined by: Your Alert Profile lists the documents that will be monitored. Surface Engineering of Steels: Heat treating low alloy PM steels October 15, Helix measurements determine the accuracy of the teeth along their length. Proceed to Checkout Continue Shopping.
Tolerances associated with gears. If the part is a helical gear, the inspection equipment rotates the avma as the probe moves axially to generate the nominal helix. Standards Subsctiption may be the perfect solution.
Continuous Cooling Transformation Diagrams.
You may delete a document from your Alert Profile at any time. Figure 1 is a copy of Figure 24 of AGMA A02 and is a sketch of a typical helix measurement trace for one flank of a tooth. Aggma otherwise specified, the maximum total helix deviation Fb of all the measured right flanks is used to determine the helix quality level of the right flanks.
Item Detail – AGMA A99 (reaffirmed September 21, )
You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Lb is the helix evaluation range used to classify the helix quality and is the length of the face width reduced slightly at each end.

The scale in the vertical direction has been expanded more than normal to help clarify the various items on the chart. Understanding Carburizing August 11, If the gear designer specifies crowning, end relief, or taper, line 1 would be modified accordingly.
The tooth at space 1 has the largest total helix deviation Fb of 0. The measuring probe is positioned against a tooth flank at one end of the face width at the tolerance diameter dT, which is one module below the tooth tips.
A primer on backlash, its purpose in gear designs.
