Novel Measuring Principle of Pitch Deviation Evaluated through Double-Flank Gear Rolling Test with Rack Probe

High-speed inspection of individual deviations (profile, helix, pitch) in mass-produced gear workshops is a problem. This paper introduces the measuring principle of pitch deviations evaluated through the double-flank gear rolling test for fast inspection in gear workshops, during which the displacement of rack probe in radial & tangential direction is measured when the work-piece is meshing with the rack probe in double-flank.
