Pitting fatigue and wear account for approximately 66% of gearbox failures. Numerous technologies have been developed to increase the service life of gears such as new designs, steel alloys, machining techniques, metallurgical treatments, and surface finishing techniques. Still, gear manufacturers are being driven to achieve not only increased cycle life, but also to do so at ever-higher operating loads. This paper, based on a patented commercial technology known as the REM® Process1, predicts that chemically accelerated vibratory finishing using non-abrasive media is capable of meeting the performance goals of gear manufacturers by producing Isotropic Superfinished (ISF) gears. Rolling/Sliding Contact Fatigue (R/SCF) testing predicts performance improvements of 16-fold in cycle life while at increasing operating loads (12.5%) without the re-engineering of existing gear systems. In this paper, “ISF” will refer to a surface that exhibits a non-directional pattern having approximately a roughness average (Ra) of 1.5 μin. produced by chemically accelerated vibratory finishing using non-abrasive media1.
