Item Detail – AGMA A05

If the part is a spur gear, the part does not rotate. Site Safety October 1, Line 2 represents the actual trace of the tooth and the deviation of the actual helix from the nominal. Surface Engineering of Steels: 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. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.


We have no amendments or corrections for this standard. Your Alert Profile lists the documents that will be monitored. The benefits of converting to helical gearing. Subscription pricing is determined by: We have no document history for this standard.

The scale in the vertical direction has been expanded more than normal to help clarify the various items on the chart. See Figure 1 for an explanation of what they represent. Figure 2 is an example of actual helix measurements of the right flanks of a tooth gear with a 4. With most inspection machines, the probe moves along the tooth parallel to the axis of the part.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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. If the part is a helical gear, the inspection equipment rotates the part as the probe moves axially to generate the nominal helix.


Site Safety June 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. Monday, December 31, This standard is not included in any packages.

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. Proceed to Checkout Continue Shopping.
