Involute splıne

[[Ün...]]

Hello ,

I have a problem measuring the following spline

I have never had a problem with involute teeth that are full teeth, but I have a problem measuring the following spline that has 4 teeth

When I enter the parameters appropriate to the picture, Gear pro shows the tooth thickness and gap width value as 18.849 mm. but it is not the same in the part.

If I play with the coefficient value and write (-0.21) suitable for the part, I get close to the part, but when I want to measure the part, it cannot find the teeth appropriately, so I cannot measure.

What am I missing?

What am I missing?

Did the suggestion from Edgars Putelis work?

This is an internal spline, but they gave you the tooth thickness? Is this a die mold for a part that will make the external spline shape or did someone mess up here?

Sorry for the late reply.

We've started producing sample parts. Yes, this is an internal gear, and we're producing it on a broaching machine.
I don't have any other data besides the section I took from the technical drawing.

My gap width setting

 

 

When I start measuring, the probe moves down from the tooth center. After touching the tooth surface on the right, when it moves to search for the tooth surface on the left, it touches the root diameter at the tooth gap center and triggers an alarm.

Should I make it move in a circular direction while searching for the teeth?

I hope this explains it. Sorry for my bad English.

Unal,

 

 By default Gear Pro want to find both flanks of a 'gap' to 'find the gear' tooth/gap alignment. What Edgar suggested above should help, make sure you have feed-in only one flank (and make sure it is correct flank). - the picture above had feed-in set to both flanks, this is likely causing the issue.

 

 Good luck.
