[To...] Posted September 10, 2025 Share Posted September 10, 2025 Is there any reason why this part can't be checked with a single down stylus? The major dia. of top gear is Ø.755" and the lower gear is Ø1.555" Does the letter "A" in the tooth quality mean anything. It appears GearPro only shows a number. Thanks in advance.

[Ch...] Posted September 10, 2025 Share Posted September 10, 2025 (edited) Tom, no reason, just be careful of shanking for profile and if there were any lead crowning etc. "A" refers to the spec, they're kind of broken up into 2, one for analytical, one for composite roll testing. Good thing is just choose AGMA 2015 and class # in Gear Pro and it will take care of the tolerance.

[Ri...] Posted September 10, 2025 Share Posted September 10, 2025 The Gear Gods will strike you down if you don't use an L-probe, a Rotary Table, and you better make sure your Lead is measured bottom to top! 3 Link to comment https://qualityforum.zeiss.com/topic/24427-newbie/#findComment-138173 Share on other sites More sharing options...
[Ch...] Posted September 10, 2025 Share Posted September 10, 2025 Gear God here, (j/k), Actually anytime I can measure without rotary table straight down I would, 1 less source of error. I do however prefer R/T over say a 10x star stylus system. Good luck, let us know how you make out. 1 1 Link to comment https://qualityforum.zeiss.com/topic/24427-newbie/#findComment-138179 Share on other sites More sharing options...
[Ri...] Posted September 10, 2025 Share Posted September 10, 2025 Yeah - I agree with that. I've had to measure helical gears with an XTR - and while I was successful, it would have been much simpler and more efficient to have had an RT. 2 Link to comment https://qualityforum.zeiss.com/topic/24427-newbie/#findComment-138183 Share on other sites More sharing options...
