Grooves on a gear
Grooves on a gear
(OP)
I have seen some gears for the agriculture machines having one or more shallow grooves on the outer dia.

What are these grooves for?
Thank you in advance for your input.

RE: Grooves on a gear
The reason for using a series of grooves on the tooth top lands is because it provides a quick and fool-proof method to visually confirm the correct gears are being used. Back in the olden days, before the availability of laser marking systems, turning a set of grooves in the OD of the gear blank was a cheap way to permanently ID the part.
