Abstract
A rolling mill tool for smooth rolling slightly convexly or concavely curved surfaces of rotationally symmetric work pieces, such as bearing journals of crankshafts, has a milling roller with a slender and hence flexing configuration for conforming the shape of the milling roller to the curved shape of the work piece surface. Such a milling roller achieves a satisfactory rolling force or load distribution. The rolling force which is applied to the milling roller by a support roller is sufficient to flex the milling roller along its lengthwise axis to assume the shape of the contour of the work piece.
Claims12
A rolling mill tool, comprising rotatable milling roller means for smooth rolling a contoured surface of a journal, pressure application roller means mounted for pressing said milling roller means against said contoured surface, said milling roller means having a length to diameter ratio sufficient for flexing and conforming a flexed shape of said milling roller means to said contoured surface of said work piece, said pressure application roller means having a configuration for permitting and causing said flexing of said milling roller means, said tool further comprising support roller means arranged for directly contacting said journal.
