Extractor tool for bearings, bushings and the like

An extractor tool for bearings, bushings and the like having a bore within which a shaft is normally received, the tool comprising an inner puller body which has a substantially cylindrical outer surface and an inner bore extending axially therealong, one end of the body including integrally therewith a grasping portion having an outer surface thereof which is substantially cylindrical for entering said bore and includes a substantially radially extending lip defined by a shoulder facing toward an opposed end of the body and including a plurality of longitudinal slots dividing said grasping portion into a plurality of grasping members each of which can flex outwardly to cause said lip to engage behind a rear face of said bearing, bushing or the like, a bolt for extending along said inner bore having a head at one end and a male screw threaded portion at an opposed end thereof arranged, with said head at said opposed end of said inner puller body, to extend outwardly at said one end of the body, a spacer sleeve between said opposed end of said inner puller body and said head and an outer washer between said spacer sleeve and said head, a wedge member having a female screw thread therein such that rotation of the bolt relative to the wedge member causes the wedge member to be drawn axially to engage an inside surface of said grasping portion to flex said grasping members outwardly, the wedge member having a small end larger than the inner bore of the inner puller body, a portion of the outer surface of said inner puller body having thereon a screw thread, a nut for engaging said screw thread so as to move axially when the nut is rotated relative to said body, holding means on said body by which the body can be grasped for holding said body against rotation, an outer puller body having an inner surface arranged to surround said screw thread portion of the outer surface, an inner washer arranged to surround the screw thread portion of the outer surface between the nut and the outer body, for engaging one end surface of said outer puller body and said nut for axial movement of the outer puller body with the nut and an opposed end face spaced from the inner puller body for engaging an abutment whereby rotation of said bolt causes said grasping portion to grasp an inner face of said bushing, bearing and the like and rotation of said nut causes said outer puller body to engage said abutment and to force said inner puller body and said bearing, bushing and the like in axial direction for removal.
