thats it exactly would like to have as much area from the o.d of the inner mandrill including splines to the outside id of the housing including splines as possible. looking at other downhole tools in the industry the wall thickness on mandrills are like 1/4" and outerhousing like...
I am a newbie at this just looking to see if it is possible. Let me tell you what i am trying to figure out. I have a 5" o.d. max on the outerhousing and i want to keep a 2" i.d. on a mandrill that rotates. i want a gear in between the outerhousing and the inner mandril that can engage...
Looking for Ideas. What i was looking for is a bearing or something like it maybe a turbine that when you turn an inside mandril. You can control or stop the outer housing. The outer housing would have counter-clockwise torque. and the mandrill would turn clockwise at max rpm of 70. Only have 4...
what i am trying figure out is if i have an outside housing with a 5" o.d. and 4 1/4" i.d. it also has 1/4" splines, with a 2 1/2" o.d. with 2" i.d. and a inside sprocket that fits between these to splines. what kinda of torque it can handle. 4340 material
what the torisonal strenth of a 5" o.d. and 4 1/4" i.d 3/8ths wall thickness tubing would be? and a 2" id with a 2 1/2 o.d. with 1/8 in splines makeing it a 2 3/4" o.d.
