Thank you both for your post, especially yours, israelkk. I purchased the ANSI B92.1-1996 for an in-depth study on splines. I was hoping to not have to go through the same process, but I can see that I will need to appeal to AGMA to gain a full understanding of the limits and the tooth thickness...
Machinery's is coming up a bit short. I know it's related to the backlash and the pitch, just not finding the connection/formula readily available.
(sorry for yelling)
GREETINGS,
IF I HAVE A STANDARD SPUR, HOW DO I FIND THE LIMITS FOR THE TEST RADIUS?, WHICH IS 1/2 THE PITCH DIA., AND CAN I USE THE SAME METHOD TO FIND THE LIMITS FOR A STANDARD HELICAL?
