Case Depth and Load Capacity of Case-Carburized Gears
The article "Case Depth and Load Capacity of Case-Carburized Gears" appeared in the March/April 2002 issue of Gear Technology.
Compared to non-heat-treated components, case-carburized gears are characterized by a modified strength profile in the case-hardened layer. The design of case-carburized gears is based on defined allowable stress numbers. These allowable stress numbers are valid only for a defined "optimum" case depth. Adequate heat treatment and optimum case depth guarantee maximum strength of tooth flank and tooth root.
