Abstract
The present invention provides a support tool for supporting a crankshaft journal during machining. The support tool includes a support housing having an opening and a support roller having a central portion received in the opening. The central portion is supported in the opening, preferably by a plurality of needle bearings, and includes opposing end portions. Opposing roller portions extend radially outwardly from each of the opposing end portions. The opposing end portions have an outer cylindrical support surface for supporting a crankshaft journal. Each of the opposing roller portions include a lateral crankshaft engagement surface and an inner surface in spaced relationship from the lateral crankshaft engagement surface. The inner surfaces are arranged adjacent to the support housing. An annular corner joins the outer cylindrical support surface and the lateral crankshaft engagement surface and is arranged within a tangential plane on the outer cylindrical support surface. In this manner, the support rollers are permitted to slide a limited amount on the crankshaft journals, and the hardened lateral crankshaft engagement surfaces are permitted to contact the thrust walls of the crankshaft without damage to the support rollers or the crankshaft journal or thrust walls.
