Ball Bearing Lock Mechanism

Ball Bearing Lock Mechanism

(OP)
Hi,

My first post here so I'm not sure if this is the correct Forum, please feel free to move if its not in the right area.

I'm looking to design a ball bearing lock mechanism similar to that found in quick-lock connectors or airline PCL connections
( http://www.google.co.uk/imgres?imgurl=http://hydra...).

This will be to secure a ~1" diameter Rod in a oilfield tool I am working on.

My issue is that I will need to calculate for bearing/shear etc and there will essentially be line or point contact.
Are there any existing design guidelines for this sort of thing?

regards

Matt

RE: Ball Bearing Lock Mechanism

Is the rod to spin in the tool, be spun by the tool (like a drill), or vibrate axially ( needle scaler, air hammer/chisel) ?

RE: Ball Bearing Lock Mechanism

(OP)
Well The rod will be spun (its essentially a drill shaft), however when locked it wont be spun. The lock mechanism is to temporarily prevent the rod from being pumped out of the body of the tool due to a piston effect from pressure across its X-sec area. I was going to use either a collet or keys but thought that a ball bearing lock mechanism may be more compact and allow for a smaller profile on the rod itself on which to lock against.
