Single Flank Test Machines

Single Flank Test is a fast inspection method for gears

The root principle of Single Flank Testing 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 Test 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.

Device with combined Noise Measurement

Inspection with Master Gear

  • Fast Composite Test (2 seconds for 10 revolutions)
  • Cycle time for measurement in both directions and handling approximately 15 seconds
  • Simultaneous recording of single flank errors, velocity and acceleration
  • Evaluation of single flank test characteristics
  • Evaluation of tooth thickness
  • Detection of noise critical elements with DISCOM system
  • Electric movement of linear axes for optimal speed and smooth travel
