US 2015/0101168 A1 · APPARATUS AND METHOD FOR REMOVING A SHAFT

Abstract

An apparatus and method for extracting shafts is provided. The apparatus includes a torquing device, threaded rod, support frame, retractable portion, tensional coupler and collar. The torquing device is disposed on a first end of the threaded rod, and the threaded rod threads through a support frame and terminates at a second end that is in a rotatably free relationship with the retractable portion. The collar is connected to the retractable portion through the tensional coupler and is capable of grasping an engagement portion of the shaft. The method includes providing a shaft associated with an object, providing the apparatus, grasping the engagement portion of the shaft with the collar, positioning the support frame of the apparatus adjacent to a support wall and applying force while rotating the torquing device of the apparatus, resulting in the shaft being extracted.

An apparatus for extracting a shaft from an object, the apparatus comprising:

a torquing device disposed on a first end of a threaded rod, wherein the threaded rod threads through a support frame and terminates at a second end, wherein the second end is in a rotatably free relationship with a retractable portion;
and
a collar connected to the retractable portion through a tensional coupler and capable of grasping the shaft at an engagement portion of the shaft.

A method for removing a shaft from an object, the method comprising the steps of:

a. Providing the shaft associated with the object, wherein the shaft comprises an engagement portion;
b. Providing an apparatus comprising a torquing device, a threaded rod, a support frame, a retractable portion, a tensional coupler and a collar, wherein:
the torquing device is disposed on a first end of the threaded rod,
the threaded rod threads through a support frame and terminates at a second end,
the second end is in a rotatably free relationship with the retractable portion, and
the collar is connected with the retractable portion through a tensional coupler;
c. grasping the engagement portion with the collar;
d. positioning the support frame adjacent to a support wall;
and
e. applying force to the support frame in a first direction and rotating the torquing device, such that the threaded rod rotates and the threaded rod and the retractable portion move in a second direction, wherein the second direction is substantially opposite to the first direction, and wherein the tensional coupler pulls the collar in the second direction.
