Abstract
A tool for extracting a bearing race from a bearing support structure. The tool is sufficiently narrow for sideways insertion into the bearing race. The tool can then be rotated within the race so that the tool engages with an annular flange of the bearing race. A threaded bolt engaged in a threaded bore of the tool is used to extract the bearing race from the support structure.
Claims17
A tool for extracting at least a bearing component held within a bearing support, comprising:
- an elongate tool body having a width along a minor axis, and a length along a major axis, said minor and major axes being orthogonal, and said major axis of said tool body being longer than said minor axis, the width of said tool body being shorter than a diameter of the opening in said bearing component, and the length of said tool body being longer than the diameter of the opening of the bearing component, wherein said tool body can be inserted in one direction into the opening of said bearing component, rotated and moved in an opposite direction to engage the bearing component for extraction thereof from the bearing support;
- said tool body having opposing ends on the major axis, each said opposing end defining a partial arc;
- and
- a threaded bore formed in said tool body along a bore axis perpendicular to the major axis and the minor axis.
A tool for extracting a bearing component including a race, said bearing component of the type having a circular opening therethrough, said tool comprising:
- a body having a threaded bore, said body having a pair of opposing ends adapted for engaging an annular flange of the bearing race;
- said body having a width for allowing sideways insertion of the tool into a circular opening of the bearing race when an axis of the threaded bore is generally perpendicular to an axis of the circular opening of the bearing race;
- and
- said body having a tapered surface for allowing rotation of the body while disposed within said bearing race.
A method of extracting a bearing component from a bearing support, comprising the steps of:
- using a tool having a threaded bore, and orienting the tool sideways such that an axial axis through the threaded bore is generally perpendicular to an axial axis of the bearing component;
- moving the sideways oriented tool in one direction generally parallel to the axial axis of the bearing component;
- rotating the tool so that the axial axis of the tool is generally parallel to the axial axis of the bearing component;
- moving the tool in a direction opposite to said one direction until the tool engages the bearing component;
- threading a bolt into the threaded bore of said tool, rotating the bolt and moving the bolt in a direction until an end of the bolt abuts with an object;
- and
- moving the tool with continued rotation of the bolt, and carrying the bearing component with the tool until the bearing component is extracted from said bearing support.
