Tooth Tips: Gear Accuracy Charts Pt. 2

The key to a proper fit for keyways. This standard is not included in any packages.

Heat treating low alloy PM steels October 15, 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. Helix measurements determine the accuracy of the teeth along their length. Log in to leave a comment. In addition to the actual helix traces, numerical values for the different helix parameters may be 95 on the printed output.

The benefits of converting to helical gearing. See Figure 1 for an explanation of what they represent.


Tolerances associated with gears. You may delete a document from your Alert Profile at any time.

Item Detail – AGMA A99 (reaffirmed September 21, )

Need more than one copy? Monday, December 31, Line 2 represents the actual trace of the tooth and the deviation of the actual helix from the nominal. Already Subscribed to this document. We have no amendments or corrections for this standard. Continuous Cooling Transformation Diagrams. This standard is also available to be included in Standards Subscriptions.

It is a complete revision in order to be more compatible with ISO. Figure 2 is an example of actual helix measurements of the right flanks of a tooth gear with a 4.

AGMA A02 – Inspection Practices – Part 1: Cylindrical Gears – Tangential Measurements

The scale in the vertical direction has been expanded more xgma normal to help clarify the various items on the chart. If the gear designer specifies crowning, end relief, or taper, line 1 would be modified accordingly. If the part is a helical gear, the inspection equipment rotates the part as the probe moves axially to generate the nominal helix. Understanding Carburizing August 11, Heat Treatment of Steel Gears July 15, Proceed to Checkout Continue Shopping.


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.

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. Line 1 represents the design helix, which in this case does not have any intentional modifications.

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. Unless otherwise ama, the maximum total helix deviation Fb of all the measured right flanks is used to determine the helix quality level of the right flanks. If the document is revised or amended, you will be notified by email. Gear Accuracy Charts Pt. A primer on backlash, its purpose in gear designs.
