Technical Examples
A method and apparatus are provided for rolling outer fillets of arcuately offset, split pin bearings on crankshafts with a pair of work rollers, each pair engaging and rolling a respective outer pin fillet. A backup roller is positioned opposite the pair of work rollers. The work rollers may be positioned above and below a centerline of the split pin, preferably about 90° apart. The work rollers can perform identical rolling operations at identical pressure and the work rollers and backup rollers are positioned to keep the adjacent tool heads in parallel planes during these rolling operations. Rolling arms carry the tool heads and stops are provided to keep rear portions of the tool arms in parallel planes against sideways forces. The work rollers and the backup roller may be mounted on the same tool arm and are movable relative to each to clamp or release a pin bearing.
