The scale in the vertical direction has been expanded more than normal to help clarify the various items on the chart. With most inspection machines, the probe moves along the tooth parallel to the axis of the part. Helix measurements determine the accuracy of the teeth along their length.

It is a complete zgma in order to be more compatible with ISO. Lb is the helix evaluation range used to classify the helix quality and is the length of the face width reduced slightly at agmz end. Log in to leave a comment. In addition to the actual helix traces, numerical values for the different helix parameters may be shown on the printed output. Understanding Carburizing August 11, As the voice of the U.


Converting to linear motion using rack and pinion.

Monday, December 31, The same procedure is used to classify the quality level of the left flanks. If the document is revised or amended, you will be notified by email. This standard is also available to be included in Ayma Subscriptions.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. If the gear designer specifies crowning, end relief, or taper, line 1 would be modified accordingly. The accuracy grade numbering system has been reversed, so that the smallest number now represents the most accurate grade.

Your Alert Profile lists the documents that will be monitored. Log into your account. We have no document history for this standard. Normally both flanks of three to four teeth equally spaced around the zgma are measured and the results magnified and charted on a strip chart or printed out.


Proceed to Checkout Continue Shopping. Figure 1 is a copy of Figure 24 of AGMA A02 and ahma a sketch of a typical helix measurement trace for one flank of a tooth.

Surface Engineering of Steels: Please first log in with a verified email before subscribing to alerts. If the part is a helical gear, the inspection equipment rotates the part as the probe moves axially to generate the nominal helix. 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.

Subscription pricing is determined by: Tolerances associated with gears. Standards Subsctiption may be the perfect solution. Add to Alert PDF. Site Safety October 1, The tooth at 951 1 has the largest total helix deviation Fb of 0.

Figure 2 is an example of actual helix measurements of the right flanks of a tooth gear with a 4. See Figure 1 for an explanation of what they represent.
