AGMA's latest addition to its live virtual online training courses takes place July 9th from 12:00 - 4:00 pm. Tooth deflections under load can cause involute interference which leads to very high tooth surface loads in regions of high sliding and low tooth curvature radius. These conditions loads can produce scoring, spalling and wear failures. Proper profile modifications applied to both members of the mesh eliminate the deleterious effects of the deflection induced involute interference and allow the gear set to yield its maximum inherent load carrying capacity. Proper profile modifications also allow a gear set to operate with lower noise and vibration levels.

Attendees will learn how teeth deflect, what involute interference really is, the potential consequences of inadequate profile modifications, and the differences between tip relief, flank relief and fully modified profiles calculate tooth deflections under load and, most especially, how to modify a gear set properly to completely eliminate involute interference. They will examine the optimum drawing definitions for profile modifications and how to interpret involute inspection charts to determine if the drawing required profile modifications have actually been produced on the gear set. A webcam on your computer equipped with a microphone and speakers/headset are required for participation. Space is limited to 20 participants per course. This course will be taught by Raymond Drago.
