Abstract:

In an embodiment of the disclosed principles, a bearing extraction tool is provided having a threaded rod, an expansion sleeve over a portion of the threaded rod and a multi-segment expansion head between the expansion sleeve and a bottom end of the threaded rod. The threaded rod bottom end includes an expansion plug having a ramped shoulder, a trunk and a stop. The expansion sleeve includes a ramped shoulder facing the ramped shoulder of the expansion plug. The outermost diameter of the expansion head occurs at a ledge portion of the expansion head. The ledge portion is small enough to fit through the central opening of a bearing to be extracted. When the two shoulders are then pushed towards one another, the ramped shoulders expand the expansion head, locking the ledge portion behind the bearing. Subsequent outward movement of the tool via a threaded fitting on the threaded rod moves the bearing outward for extraction.
