Abstract
Apparatus for insertion of an object into a close clearance hole utilizing a double taper starter system. The apparatus includes a first taper to align the object radially; a narrow section of length such that with the object tilted to the angle of the first taper, clearance in the hole is maintained; a cut-back segment of either constant diameter or reverse taper geometry; and a second taper of approximately the same size and shape as the first taper to align the object angularly. The apparatus of the invention can be advantageously used in mechanized assembly processes, the assembly of shafts into bearings, and in thermally assembled or regular interference fits.
