Attached is the pdf requested. Yes it is fillet root.https://files.engineering.com/getfile.aspx?folder=a7e6ea0e-b5aa-42e9-8633-d94afdd89727&file=591-1753_Disc_Friction_2.pdf

HOPEFULLY YOU CAN OPEN THE ATTACHMENT AND VIEW THE SPLINED PART. YES IT IS A DIE PUNCHING AN INTERNAL SPLINE. WILL IT WORK YES. BUT THE DIE PUNCH WILL NOT LAST, ESPECIALLY WITH SHARP CORNERS. I'm THINKING THE "R" CANNOT BE BIGGER THAN THE DISTANCE BETWEEN THE MINOR AND PITCH...

Hello, I am developing a die that will produce an involute interior spine die. With a die I cannot have sharp corners. Is there some kind of universal size for any radius on the tips of the spline? Everything I look at shows sharp corners. I have developed the part in Gear Trax and...

Can I stress relieve 50YF SAE 1392 and hold the hardness? Print is asking for Core hardness Rockwell B77 MIN. If so at what temp, how long? We also melonite after forming.

the word hole should be hold!

Flexplate dimensions above are b4 weld. Yes, we are looking in to using machining to correct. The out of flat problem I'm not sure of yet. The flexplate comes out of a die, which needs more work to correct some problems. Right now the flexplate is held by the machined hub on a center post. I...

For those helping me here is a pic of the weldment on the balance fixture.

You are correct on the numbers 360 g mm. Is the g for grams and the mm is metric? Maybe I'm not reading correctly. Our company only makes the flexplate/ring gear weldment. I have no access to the crankshaft or engine. I believe this is going into a UTV. So I worked on balancing each...

We have a balancing machine. We mount a fixture that uses a center plug to keep the weldment concentric. The machine/fixture is setup or calibrated with the weldment 3 times before actual balancing is initiated. We balance several other ring gear/flexplate weldments, but none with this many...

I have a weldment of the above parts and cannot get the balancing below .5 or below 1. We weld the flexplate to the ring gear first in a fixture. 2nd fixture welds the 1st 2 components to a hub. and then we weld the timing locator ring in the 3rd weld fixture. We are getting 2.41-2.61 for...

Thank you for the info. I did find the certs from the steel manudavturing and it does say carbon at .7

the only other note listed is a stress relieve at 454°C to 510°C for 2 hours min.

Print says: SAE J403 SAE 1020 THRU 1080 OR SAE 4130 THRU SAE 4145 OR SAE 1536 THRU SAE 1566 HARDNESS rB 84 MIN. I am looking for a shear strength or carbon to calculate tonnage for punch press.

NO calls for SAE 1566
