Gear measurement EWP+ZWP

Automatic measuring machine for gear inspection with single-flank and double-flank contact rolling test methods to determine gearing errors.

Gear measurement EWP+ZWP

EWP Measuring principle:

  • The test piece is driven by a master gear and simultaneously subjected to a braking torque via another gear; As a result, the master gear rolls off with defined force onto the tooth flank
  • Roll off both tooth flanks by changing the direction of rotation
  • Define the axis distance between test piece and master gear (can be adjusted individually)
  • Measure the rotational angle difference between the test piece and the master gear to draw conclusions about gearing errors Fi´, fi´ and flank play f´

ZWP Measuring principle:

  • The test piece is driven by the master gear;
  • As a result, the master gear is pressed into both tooth flanks with a defined force
  • Measure the change in axis distance between the test piece and the master gear to draw conclusions, mainly about concentricity deviations Fr´´ and gearing errors Fi´´, fi´´

Features:

  • 100% inspection with very short cycle time
