Single flank gear roll testing

It is a highly sophisticated and accurate method of measuring and evaluation of your gears where both flanks (left and right) are measured individually in fixed axis distance and/or required postion of backlash.

Following single-flank deviations can be measured and evaluated:

  • Fi´- tangential composite deviation
  • fi´ - tooth to tooth composite deviation
  • fl´- longwave component
  • fk´- shortwave component
  • j    - backlash
  • Fp - total pitch deviation
  • fpt - adjacent pitch deviation
  • fu - diffrence between adjacent pitches
  • Fr - radial runout
  • Contact pattern, V/H cycle, FFT analysis


Principles of single-flank gear roll testing:

  •     mounting distance is fixed during the measurement
  •     left and right flanks are tested separately
  •     both spindles are equiped with high-precise rotary encoders
  •     results of transmission error
