Very High Cycle Fatigue Testing of AMS 6308 Steel

In this paper, ultrasonic fatigue testing results for “core hardened” AMS 6308 gear steel are presented. AMS 6308 is a gear and bearing steel with high tempering resistance and high hot hardness case targeted to high temperature applications

Clean Steel Standards and Optimizing Gear Design

Gears serve as essential mechanisms in a wide range of mechanical equipment, helping to transmit torque, adjust rotational speeds, transfer power, distribute load and more. Used in necessary applications such as automobiles, energy systems, aerospace and industrial equipment, gears must be able to operate for long periods without maintenance. While gears can be made from a diverse assortment of materials, carbon and alloy steel offer superior benefits in terms of strength, durability and cost efficiency. As a remarkably recyclable material, steel may also be a preferable choice for environmentally conscious manufacturers.

Tooth Root Bending Strength of Shot-Peened Gears Made of High-Purity Steels up to the VHCF Range

Standardized methods, like AGMA 2001-D04 or ISO 6336 for the calculation of the load carrying capacities of gears are intentionally conservative to ensure broad applicability in industrial practice. However, new applications and higher requirements often demand more detailed design calculations nowadays; for example: long operating lives in wind power gearboxes or fewer gear stages and higher speeds in e-mobility applications result in higher load cycles per tooth in a gearbox.

The XL Gears Project

Much of the existing guidelines for making large, high-performance gears for wind turbine gearboxes exhibit a need for improvement. Consider: the large grinding stock used to compensate for heat treatment distortion can significantly reduce manufacturing productivity; and, materials and manufacturing processes are two other promising avenues to improvement. The work presented here investigates quenchable alloy steels that, combined with specifically developed Case-hardening and heat treatment processes, exhibits reduced distortion and, in turn, requires a smaller grinding stock.
