ROLLING GEAR TESTERS 

Our Rolling gear testers

       Type of gears measured :
  • Spur gears
  • Helical gears 
  • Bevel gears
  • Worm gears /endless screws                                                                               

       External or internal gear


       The sensors proposed for the measurements are : 

  • Dial indicator (visual reading of the measured values by the user) (A)
  • Lvdt sensor connected to a measurement display (B)
  • Incremental gauge connected to a computer. The measured values are computed to calculate the normalized values (F"i, f"i, Fr). The software will also determine automatically, if the measured gear is "in conformity" or not, based on some criteria pre defined by the user. (C)



                 
                      (A)                                      (B)                                         (C)


Parameters measured / Calculated

     Normalized parameters

  • radial composite error F"i
  •  tooth to tooth radial composite error f"i
  • runout Fr 
      => Calculation of the real quality class of the measured 
            gears.

      Other characteristics measured/ calculated

  •  Detection of shocks on the teeth
  •  Calculation of the distance between axes
  •  Acoustic noise prediction : Some calculation extrapolated  from the measurement graph can also be used to  predict if some acoustic noise will be generated by the  worm in its final use.
