locking taper angle
locking taper angle
(OP)
Hi all,
what is the standard angle for a locking taper? Does it depend on mating materials?
A taper machined onto two mating parts such that when the parts are mated the frictional forces are so great will not rotate or move with respect to one another. No clamping forces are required to keep the parts joined, but considerable force is required to separate the items. This is an extremely rigid and accurate method of joining arbors and spindles.

Brown & Sharpe & Morse are locking [~2-3deg], whereas "Self releasing" tapers are 16 deg

Morse, Brown and Sharpe, Jarno tapers, etc, are mostly less than 4 degrees a side, See "Machinery's Handbook"
Machine tool spindle tapers that use drawbars or other clamping devices tend to have much higher angles.

She works like a dream. The semi-cone angle of 7 degrees is ideal for reasons discussed above.
