In the previous article, we discussed the fact that chemically accelerated/assisted superfinishing, also known as isotropic superfinishing, was introduced into the gear industry more than twenty years ago. In gear mesh, the lubricant thickness is greatest across the pitch line where the system exhibits pure rolling action. This paper will outline NRTC-CRI funded testing of a Bell Model 427 main rotor gearbox with ISF processed gears. Isotropic superfinishing improves the durability of a gear through the reduction of roughness, allowing more load to be transmitted over the surface area. The surface roughness of the mating components and the chosen lubricant (and its operating properties) are primary factors in determining the potential for scuffing. Processes such as isotropic superfinishing can generate a very low surface roughness on complex geometries through a planarization mechanism. Isotropic superfinishing is an additional manufacturing step to finalize the gear topography. Also, the test gears were run in both an as-ground condition and after isotropic superfinishing (ISF) condition. isotropic superfinishing occurred in 2009 with the invention of chemi - cally and mechanically accelerated superfinishing processes (called the Rapid ISF® Process by REM). In. Similarly, gears in auto racing transmissions, which operate under high loads with high pitch line velocities, have benefited from this isotropic superfinishing process with teeth finishes of R a from 0.
