QUINDOS Step Gear / Roller GearMTW-510-STG-001

The package QUINDOS Step Gear / Roller Gear is used to inspect the shape and functionality of step gears (roller gears) on precision Coordinate Measuring Machines.

The step gears / roller gears can have cylindrical or globoid carriers.

By means of the transmission law, i.e. the relationship between the rotation angle of the carrier and the movement of the roller axis, the QUINDOS software can calculate the surface points with their normal directions.

The measuremend of a Step Gear / Roller Gear with QUINDOS includes:

• Generation of nominal surface points
• Evaluation of the deviations perpendicular to the surface
• Calculation of the deviations of the transmission law
• Slot width (clearance)
• Contact pattern analysis
• Axial best fit

Due to the usually tight tolerances of a step gear / roller gear, only precision Coordinate Measuring Machines with small probing errors P and THP (according to ISO 10 360) and High-Speed-Scanning capability (i.e. Leitz PMM-C or Leitz Reference) should be used for such measurements.

With Leitz QUINDOS the inspection of step gears (roller gears) can be done on coordinate measuring machines without a rotary table. This means the step gears can be mounted on a pallet and measured with maximum throughput and efficiency.
