Gear Metrology

Length of Course
One day.
(Please contact for next available training program on following mail id or contact no.)
Course Description

This comprehensive one day program provides a solid introduction for those new to the gear industry as well as an excellent review for experienced technologists. The Basic Gear Metrology module focuses on the involute helicoid system that is widely used for cylindrical gears and splines. Composite and elemental measurement methods are described and contrasted. Categories, causes, and consequences

The Calibration and Metrology module explores the subject of measurement validity beginning with discussion of important but often overlooked metrology issues. New traceability and calibration concepts are outlined. An introduction to statistical estimation of measurement uncertainty is included.

The Gear Accuracy Standards module brings participants up to date with the recent changes in

A Spline Measurement Module can also be included in the program.

Training groups are kept small so that individual concerns may be fully addressed.


Identify why gears have failed - 90% of premature failures have excessive geometry errors


Identify the causes of manufacturing errors - we tell you what the results mean and how to correct them


Minimise noise from a gear set - poor specification or manufacture causes noise


Increase potential power density - accurate gears transmit morepower

5 Prove your gears were supplied to specification
6 Reduce premature failure risks
7 Benchmark your suppliers manufacturing capability
8 Minimise product through life cost
9 Increase your competitiveness
