AGMA AGMA, in cooperation with ABMA, is offering this course on rolling element bearings for those involved in industrial equipment design, reliability, and maintenance. It will include a basic overview of rolling bearings, their selection, precision and mounting considerations, service life estimation and lubrication related influences. A hands-on damage analysis session is the featured portion of this program. There are eight courses available at Gear Expo this year. Register today – early bird deadline is this FRIDAY.

Explore just what High Profile Contact Ratio (HCR) gears are and under what circumstances they can be an advantage. Learn when HCR gears are not appropriate and why. This fast-paced session will cover the detailed tooth geometry changes that are required to effectively achieve optimum performance and benefit. We will discuss how the load distribution along the involute profile changes when the contact ratio increases above two. Because of the longer, generally more slender teeth on a HCR gear the heat treatment and profile modifications that are required for good performance are distinctly different from those for a standard contact ratio gear. The load capacity rating of HCR gears requires the application of modified AGMA analyses as the AGMA Standards specifically do NOT address gears with profile contact ratios greater than 2.0 thus we will also cover the changes required to successfully rate HCR gears.
