Gear Measurement and Inspection

  The next generation of Ultra High Accuracy CMM's are making Gear Inspection more of a reality, it is often assumed the only way to really check a gear accurately is by inspecting it on a dedicated Gear Checking Machine, however that is most definitely not the case anymore.

It is true that depending on the class of gear that most CMM's are not really capable of inspecting and getting accurate repeatable results, but today's UHA (Utra High Accuracy) CMM's are extremely accurate indeed, and are not only capable but also much more versatile than any dedicated Gear Checking Machine.


The advantages of Inspecting Gears using a CMM

  Choosing the correct CMM is very important, and Leitz measuring machines, Leitz probe heads and QUINDOS software are designed to inspect virtually any geometry, including all types of gear or gear cutter, with or more importantly without a rotary table.  

  Some important things to consider:  

·        Better system accuracy, especially for the inspection of large and heavy gears

·    Higher throughput due to pallet measurements

·    Easy setup, no centering or alignment of the gear required

·    Less investment and less maintenance costs

·    Software certification: QUINDOS Gear software is certified by the PTB (Physikalisch-Technische Bundesanstalt) of Germany.

·    Gear standards: Evaluations according ISO, DIN, AGMA, JIS and CNOMO, all included in the QUINDOS Gear basic package. Also available is gear evaluation according to Caterpillar standards.


  Other Considerations that Gear Manuafcturers are not often aware of:  


  • Small and medium size gears: comparable to a dedicated gear measuring machine

  • Large and heavy gears: Leitz gear inspection centres do provide better accuracy because no rotary table is used.



Measuring speed:

  • Small gears: similar to a dedicated gear checker but much higher throughput with pallets

  • Large and heavy gears: faster than a dedicated gear measuring machine because the gear does not need to be turned



Flexibility: If your Leitz gear inspection centre has some idle time, you can use it as a high precision coordinate measuring machine to inspect just any component.
