Contact Fatigue Characterization of Through-Hardened Steel for Low-Speed Applications like Hoisting - July 2017

The article "Contact Fatigue Characterization of Through-Hardened Steel for Low-Speed Applications like Hoisting" appeared in the July 2017 issue of Gear Technology.

Summary
In several applications like hoisting equipment and cranes, open gears are used to transmit power at rather low speeds (tangential velocity < 1m/s) with lubrication by grease. In consequence those applications have particularities in terms of lubricating conditions and friction involved, pairing of material between pinion and gear wheel, lubricant supply, loading cycles and behavior of materials with significant contact pressure due to lower number of cycles.
