I know that AGMA recommends approach action in a gear mesh to be below 50% and I understand why. What I haven't figured out or found any reference for is what would be the lower limit of approach action percentage? I've seen and even designed sets as low as 33% approach action and as far as I...
We have some splined couplings that are designed to have an intference fit of .002-.004 on the teeth. The spline is 23T 8/16 DP 30°Pa spline.
I'm trying to figure out how hot the coupling hub needs to be to assemble onto the shaft. I know how to do this for regular circular bores but I'm not...
I have a integral helical pinion that has a larger bearing diameter behind it. I can't find how to calculate how much length beyond my effective tooth length the cutter will need. I would like to minimize/eliminate the hob cutting into the bearing diameter and space is a concern. Does anybody...
I am looking for an equivalent "American" steel for BS 970605M36T. I looked through the Metals Black Book and searched around the internet but could not find anything on this spec. I am looking into this for someone else and they tell me it is a British standard that is called out on a gear...
Hello everybody,
I'm fairly new to the forum and have a question. A customer wants me to calculate the break away torque for a redesigned increasing gear drive. We are changing the ratio so he needs to select a new electric motor and this is the first time a customer has asked me for a break...
