Abstract:
A spring collet clamping system comprising:a rotatable shaft; a collet disposed about the rotatable shaft; and a reusable spring clamp having a generally cylindrical, three-turn helical portion with arms extending from generally opposite portions thereof, and an inner diameter of the coil portion being smaller than an outer diameter of the collet, the spring clamp being substantially balanced about an axis of the coil portion and being rotatable by force against the arms to enlarge the inner diameter of the coil portion, and releasable to allow radial contraction of the spring portion on the collet; whereby when the generally cylindrical, helical coil portion of the spring clamp is disposed about a portion of the collet the collet is clamped about the rotatable shaft for rotation therewith, balanced by the arms.
