One Flank Gear Rolling Inspection Machines

One Flank Gear Rolling Inspection is a fast inspection method for gears

The root principle of One Flank Gear Rolling is meshing a Master Gear (a near perfect gear) and a workpiece with a fixed axial distance. By using a braked axle only one flank (left or right, thrust or trailing) is meshing.

Both axes are fitted with a rotary encoder, allowing to compare the actual-/desired angle. In contrast to Double Flank Gear Inspection an independent evaluation of both flanks is possible. Depending on workpiece geometry FRENCO is offering different variants of Machines

All Machines are equipped with FRENCO Measurement Electronics MEG32. Evaluation is done with FRENCO Software RMpro.
