[b] Taper Connections for Mechanical/Structural Applications [/b]
(OP)
I am looking for information and/or direction to literature on recommendations of using taper connections for pipe or round tubing to be used for structural applications. For example, I would like to use tapered connections to support a pipe at each end – just as a beam fixed at both ends. Would Taper Morse insure tight joints that can carry bending moment? Information desired is regarding the feasibility in using taper connections for any structural applications. Does this type of connection would insure long term joint integrity and sustain shear and bending moment?

The pin might be plenty strong, but check for tearout in the pipe

The only saving grace is if the taper or the socket are relatively elastic then you may be able to assemble it with enough force to keep it locked up.

What do you think would happen then if I secure the connection on each side with a bolt in the axis? Don't you think if anough torque is applied I can keep the connection able to resist moments?

Incidentally please don't try and use html in the thread title, it doesn't work, it's rude, and it looks messy.

-You need a way to positively retain the end plates. Friction alone it probably not enough. [If the taper angle tangent is greater than the friction coefficient, it'll slip.] A co-axial thread is a good way {like on the AN-386]
- check for Hertzian contact stresses to make sure it doesn't "bell-mouth."
- you can't have more than one of these between two parts - only one will be tight due to tolerances.

However, I am not sure I understand well how you would use the part 'AN-386'. I think a standard bolt would do the job..

[Why reinvent the wheel? Great-Grandpa's tax $$ probably paid for the design - Grandpa probably flew it!
The official spec has been superceded to NASM386, but you can get the prior gov't dwg @: http://assist.daps.dla.mil/online/start/
if you're registered there.
