Calculating flats on a shaft
Calculating flats on a shaft
(OP)
I have a shaft that has had 4 flats cut into it. I want to know the flat width, but do not have access to the shaft. I know there must be a way to do this calculation, but I cannot think of it.
Here is the data I have:
- Shaft D: 3.199", giving an OD of 10.04486"
- Flat depth: .021
- Total of 4 flats.
Is there a way to extrapolate the flat width?
Thanks.

Never mind, I apologize. Pythagorean Theroem. Ive been out of school too long I suppose. :)
RE: Calculating flats on a shaft
width of the flat = 2 x sqrt{(R^2 - (R-.021)^2}
