US 6,883,217 B2 · Apparatus for disassembling mating taper connections

Abstract

A disassembly tool for disassembling components secured together by a mating taper connection. The disassembly tool of the present invention includes a self-tapping sleeve for securement in the longitudinal bore of the component having the female portion of the locking taper connection. The self-tapping sleeve includes self-tapping external threads for securing the self-tapping sleeve in the longitudinal bore of the component having the female taper. The self-tapping sleeve further includes a longitudinal bore having internal threads mating with external threads of a threaded inner rod. In use, the self-tapping sleeve is engaged in the longitudinal bore of the component having the female taper. The threaded inner rod is thereafter threaded through the threaded longitudinal bore in the self-taping sleeve until the distal end of the threaded rod abuts the end of the component having the male taper and forces separation of the locking taper connection.

Dependent claims

A disassembly apparatus for disassembling a mating taper connection in a pair of interpenetrating pans, a first of the interpenetrating parts including a longitudinal bore having a female taper, a second of the interpenetrating parts including a male taper, said disassembly apparatus comprising:

a sleeve for engaging the first of the interpenetrating parts, said sleeve including a longitudinal bore having internal threads, said sleeve including external self-tapping threads, said sleeve sized whereby the longitudinal bore of the first of the interpenetrating parts accommodates said sleeve, said external self-tapping threads sized whereby rotation of said sleeve with said sleeve positioned in the longitudinal bore of the first of the interpenetrating parts threads the longitudinal bore of the first of the interpenetrating parts and secures said sleeve therein;
and
an inner rod having external threads, said external threads of said inner rod cooperating with said internal threads of said sleeve whereby rotation of one of said inner rod and said sleeve relative to the other of said inner rod and said sleeve causes axial displacement of said inner rod relative to said sleeve, said inner rod having a distal end.
