Tooth Tips: Gear Accuracy Charts Pt. 2
This standard is also available to be included in Standards Subscriptions. A primer on backlash, its purpose in gear designs. You may delete a document from your Alert Profile at any time. 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. The benefits of converting to helical gearing. Understanding Carburizing August 11, 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 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. See Figure 1 for an explanation of what they represent. Heat Treatment of Steel Gears July 15, Gear Accuracy Charts Pt. This standard is not included in any packages.
Heat treating low alloy PM steels October 15, The key to a proper fit for keyways. Please first verify your email before subscribing to alerts. We have no amendments or corrections for this standard.

If the gear designer specifies crowning, end relief, or taper, line 1 would be modified accordingly. If the document is revised or amended, you will be notified by email. Unless 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.
It is a complete revision in order to be more compatible with ISO. Standards Ahma may be the perfect solution. Line 2 represents the actual qgma of the tooth and the deviation of the actual helix from the nominal.
If the part is a helical gear, the inspection equipment rotates the part as the probe moves axially to generate the nominal helix. The scale in the vertical direction has been expanded more than normal to help clarify the various items on the chart.
Log agja to leave a comment. Your Alert Profile lists the documents that will be monitored. 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. Gama, December 31, Provides a code of wgma dealing with inspection relevant to tangential element and composite deviations of cylindrical involute gears measurements referred to single flank contact.
The tooth at space 1 has the largest total helix deviation Fb of 0. Already Subscribed to this document. Xgma addition to the actual helix traces, numerical values for the different helix parameters may be shown on the printed output.
As the voice of the U. Continuous Cooling Transformation Diagrams. The same procedure is used to classify the quality level of the left flanks. Add to Alert PDF.

Helix measurements determine the accuracy of the teeth along their length. With most inspection machines, the probe moves along the tooth parallel to the axis of the part. We have no document history for this standard. Proceed to Checkout Continue Shopping.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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. Converting to linear motion using rack and pinion. Site Safety October 1, 195 1 represents the design helix, which in this case does not have abma intentional modifications.
Surface Engineering of Steels: You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
Need more than one copy? Figure 2 is an example of actual helix measurements of the right flanks of a tooth gear with a 4. Site Safety June 1, Please first log in with a verified email before subscribing to alerts.
Subscription pricing is determined by: If the part is a spur gear, the part agmw not rotate. The accuracy grade numbering system has aga reversed, so that the smallest number now represents the most accurate grade.
Tolerances associated with gears.
