A puller device for pulling bearings, gears, wheels and pulleys from objects such as shafts and axles and other machine parts. The puller device includes a jaw support assembly; jaw members being in operable communication with the jaw support assembly; a jaw actuating assembly being supported by the jaw support assembly and including a jaw guide member being in operable communication with the jaw members; and an elongate push member being adjustable relative to and in operable communication with the jaw support assembly for urging against an object to facilitate the removal of a press fitted work piece.
1. A puller device comprising:
a jaw support assembly;
jaw members in operable communication with said jaw support assembly, wherein said jaw support assembly includes at least one pivot member pivotally attached to at least one of said jaw members for increasing radial movement and increasing clamping force of said at least one of said jaw members, wherein said at least one pivot member includes at least one linkage member pivotally attached to at least one of said jaw members and being in operable communication with said jaw support assembly, wherein said at least one pivot member includes a collar, wherein said at least one linkage member has a proximate end and a hole disposed therethrough approximate to said proximate end with said proximate end pivotally attached to said collar, wherein said jaw members are pivotally attached to said at least one linkage member for increasing radial movement and increasing clamping force of said jaw members, wherein each said jaw member has a proximate end pivotally fastened to said at least one pivot member and has an arcuate distal end adapted to being engagable to a work piece being removed from an object, wherein each said jaw member has flanges extending along either side of said jaw member;
a jaw actuating assembly supported by said jaw support assembly and including a jaw guide member in operable communication with said jaw members; and
an elongate push member being adjustable relative to and in operable communication with said jaw support assembly.
2. The puller device as described in claim 1 , wherein said jaw guide member includes transverse support members being spaced apart and also includes brace members interconnecting said transverse support members.
3. The puller device as described in claim 2 , wherein said support members are planar members and include a first planar member and a second planar member with said planar members each having an opening being centrally disposed therethrough.
4. The puller device as described in claim 3 , wherein said second planar member further has T-shaped slots being disposed therethrough near a perimeter thereof as viewed above or below the centrally-disposed opening, said flanges of each said jaw member being movably and engagably received in a respective said T-shaped slot with said jaw guide member pivoting said jaw members relative to said at least one pivot member and to the work piece.
5. The puller device as described in claim 4 , wherein said jaw actuating assembly also includes a jaw guide actuating member supporting said jaw guide member and being in operable communication with said jaw support assembly.
6. The puller device as described in claim 5 , wherein said jaw support assembly further includes a hollow threaded shaft with said collar being securely supported thereto, said jaw guide actuating member being a handle and being threaded upon said hollow threaded shaft.
7. The puller device as described in claim 6 , wherein said hollow threaded shaft is disposed through said centrally-disposed opening of said first planar member with said brace members being attached at the perimeters of said first and second planar members, said first planar member being engagable to said handle.
8. The puller device as described in claim 6 , wherein each said elongate push member is a rod being threaded through said hollow threaded shaft and being engagable to the work piece.
