In Reply to: Face width of bevel gears posted by Rick Pagn on August 15, 2008 at 05:31:13:
From just looking on this pinion gear one may notice a small number of teeth. Because of 10 teeth the pitch line is probably close to the root of the tooth in order to reduce undercut on the root. If so, the Gleason definition odes not really work for this particular gear. The gear has a large chamfer on the TOE, as a result of the flat face. If to follow the definition of Gleason the face width would be significantly over sized, which will result in incorrect load rating calculation. So it is better to measure the face width in the middle of the tooth if you need it for load rating. For manufacturing, you should use the measurement along the root.
