Abstract: The blade of radial gear shaver is required to arrangement with variable pitch ordination, a prototype equipment can not meet the need of the variable pitch blade. Designing a new equipment with automatic indexing, cutting feed and hackling variable pitch, the paper provides a necessary condition for the process engineering of radial shaving gear.

Key words: Gear shaving, Hackling pitch, Number control, Bootstrap method, Damping force degradation mechanism, Extreme small sample, Reliability test, Hydraulic damper
