Title: Allen V Keller: Innovator in Aerospace Bearing Manufacturing
Introduction
Allen V Keller is a notable inventor based in Torrington, CT (US). He has made significant contributions to the field of aerospace engineering, particularly in the manufacturing processes of bearing rolling elements. His innovative approach has led to advancements that enhance the performance and durability of aerospace components.
Latest Patents
Keller holds a patent for a manufacturing process for aerospace bearing rolling elements. This patent describes a method of treating bearing rolling elements or bearing rings after a hardening and temper heat treatment. The process includes a tumbling treatment followed by a duplex hardening treatment. Additionally, the method involves treating the bearing rings with a peening treatment and then applying the duplex hardening treatment. This innovative duplex hardening treatment may consist of a nitriding process that increases surface hardness and compressive residual stress. The result is a deep surface/sub-surface residual stress that exceeds the depth of the maximum operating von-Mises shear stress, along with an ultra-hard surface that possesses a high magnitude of compressive residual stress. Consequently, the bearing ring and rolling elements exhibit significantly enhanced rolling contact fatigue resistance and improved resistance to surface imperfections and debris.
