References The ISF Process is a suite of chemically accelerated surface finishing and polishing technologies that generate low Ra surfaces with non-directional/isotropic surface textures and exceptionally high bearing ratios. This is an engineered finish with the benefit of producing a low friction surface that will reduce rolling resistance and hence contact stresses. Gear Repair for Helicopters and Wind Turbines via Isotropic Superfinishing Posted by Justin Michaud on Tuesday, June 6th, 2017 in The wind turbine, aerospace, and helicopter gear industries recognize the importance of surface finish and surface texture for maximizing component and system performance. Isotropic Superfinishing of S-76C+ Main Transmission Gears. Probably (as long as the cost is acceptable) I will only perform the isotropic superfinishing treatment because nitriding requires special attention and knowledge of the metal alloy of the shaft, the heat treatments it has previously undergone, the desired depth of treatment, etc. Isotropic superfinishing is an ideal process for repairing damaged gear flanks and bearing surfaces found on used wind turbine gears. The Rapid ISF Process increases fuel efficiency and power density and is compatible with a ju. The wind turbine gearbox industry has also used isotropic superfinishing as a method of repairing damaged gears for over a decade. ABOUT THE AUTHORThe gear set on the right shows the mirror-like finish of the Isotropic Superfinishing treatment compared to a non-finished ring and pinion. High-Density Ceramic Tumbling Media is a heavier, longer-lasting media. . Isotropic superfinishing in the form of CAVF has been shown to be an effective method of removing corrosion. The turret speed, spindle speed and direction of rotation and depth in the media are controlled with. Due to its attractive properties of strength, durability, corrosion resistance, and its lightweight nature, there. For this reason, Arrow has added the capability of Isotropic Superfinishing. The gearbox. The texture consists of only random scratches and shallow dents. Figure 4 is the roughness measurement result of this inner bearing race. The surface finish of gear teeth is directly related to the service life and overall quality of aerospace gearing. Potential to Repair Damaged Components.
