Friction Coefficient of Differently Treated Steel Surfaces

摘要

My company designs and manufactures rotating machinery, and recently we adopted ion-nitride finish to our shafts. We have been led to believe that this process reduces the coefficient of friction used to calculate torque transmitted through a tapered hub interference fit. Currently we use a friction coefficient of 0.15 per ANSI/AGMA 9003 for the calculation Do you know how much reduction, based on your knowledge of the finishing process and torque transmission?
