Abstract
A bearing extractor having a support element in which a rod is positioned such that the rod is capable of expanding, within a bearing, the prongs of a bearing grasping assembly. Once the prongs of the bearing grasping assembly grasp the bearing, the bearing is raised by the rod until the case surrounding the bearing engages the support element. Thereafter continued raising of the rod removes the bearing from its case.
Claims2
A bearing extractor, comprising:
- U-shaped support having a flat top portion and a pair of legs capable of impacting a case surrounding a bearing to be extracted;
- a bearing grasping assembly, said assembly including a nut-shaped support having internal threads and a pair of expandable prongs extending from said nut-shaped support, each of said prongs having internal threads and a ledge formed at the bottom thereof for engaging the bottom of said bearing;
- a rod, said rod being slidable and rotatable within said top portion of said U-shaped support and rotatable within said bearing grasping assembly, said rod having threads for engaging said threads of said nut-shaped support and said prongs, and said prongs having a preselected internal configuration for engaging an end of said rod in order to expand said prongs against the interior surface of said bearing when said rod is rotated into said nut-shaped support, and said rod having a handle at another end thereof;
- and
- means for encompassing said rod for adjustably supporting said rod with respect to said U-shaped support;
- whereby after said prongs of said bearing grasping assembly are expanded against the interior surface of said bearing, outward movement of said rod draws said bearing case into contact with said legs of said U-shaped support, and further outward movement of said rod removes said bearing from said bearing case.
