The design of gear blanks or flanges has traditionally been driven by weight reduction. Recently innovative companies have started to use the gear blank design to tune the system dynamics to reduce gear whine.
Forest City Gear is doubling down on its strategy to produce most of its critical gear blanks in-house by adding new capacity, and capabilities, to its state-of-the-art 8,500 sq. ft. precision gear blanking facility.
In this article, the focus is put on one technology, X-ray diffraction (XRD), and more specifically, residual stress measurement by way of XRD for both process development and quality control.
