QUINDOS Worm WheelMTW-510-WWL-001


Measurement of Worm Wheels for Cylindrical Worms on Leitz Coordinate Measuring Machines.


The package QUINDOS Worm Wheel provides the measurement and evaluation of worm wheels (worm gears) for cylindrical worms on precision Three Coordinate Measuring Machines.

The cylindrical worm can be of generation type ZA, ZI, ZN, ZK and ZC (see DIN 3965). The geometry of the worm wheel is calculated by QUINDOS as a conjugate gear to the worm. This is a unique feature not offered by any other worm wheel inspection system. Others usually just measure one tooth of the worm wheel as a master.

Besides other evaluations, this QUINDOS package can also best-fit the axial position of the worm wheel to find the optimum mesh position.
A significant advantage when measuring long worms, compared to a dedicated Gear Measuring Machine using a rotary table.


Inspection of worm wheels with QUINDOS on Leitz CMMs provides following evaluations:

  • Pitch in the mean plane
  • Tooth thickness
  • Runout
  • Dimension over balls
  • Profile
  • Flank
  • Topography
  • Axial best-fit with displacement

The package QUINDOS Worm Wheel generates automatically the moving path and all required probing points and scan lines, including start and stop points and stylus changes, for CNC Coordinate Measuring Machines (CMM).

For the inspection of worm wheels on Leitz Measuring Machines with QUINDOS a rotary table is not required, i.e. several worm wheels can be measured on a pallet. This leads to a tremendous increase in throughput compared to a conventional single purpose gear tester.

Due to the usually tight tolerances of worm wheels, only a high precision 3D Coordinate Measuring Machine (CMM) with a small probing error P and scanning capability (i.e. Leitz PMM-C) should be used for such measurements.
