Locking Taper Assembly Strength

[jscottwallace]

Howdy,

My question has to do with the holding force of locking tapers such as Morse and Browne & Sharp; i.e. how can I predict the force required to disassemble a taper assembly by pulling only? Is there a formula/data (theoretical or empirical) that relates the variables (angle, modulus, surface finish, coef. of friction, insertion force, etc.) to the force required to disassemble the joint?

Everything I've seen on taper locks rates them for the torque they can transmit. I suppose you could convert the rated torque to a tangential force on the shaft and that would be good starting point for the force required to slip.

Also, if slipping axially on the shaft is your main concern, you could step the shaft, assuming the slip is in one direction.

Hope this helps.

Could you point me in the direction of a source of the torque data you referred to in your post?

Thanks
