Abstract

The present invention relates to a method and apparatus for grinding crankpins of a crankshaft. The method is comprised of the steps of mounting the crankshaft between centres; and attaching radially outer regions of the flange to a rotational drive to rotate the crankshaft about its main axis, via a coupling which is torsionally rigid in a plane generally perpendicular to the axis of rotation of the crankshaft but which is readily deformable in other planes to accommodate misalignment. The method further includes advancing the grinding wheel to engage a crankpin region of the crankshaft; and synchronously controlling the position of the grinding wheel whilst the crankshaft is rotated thereby to follow the planetary motion of the crankpin so as to maintain grinding contact between the wheel and the pin. The apparatus is a grinding machine adapted to grind a crankpin region of a crankshaft by synchronously advancing and retracting the grinding wheel as the crankshaft is rotated so that contact is maintained between grinding wheel and crankpin during grinding of the pin. This assures that a true cylindrical surface is ground on the pin.
The grinding machine is comprised of a drive unit for rotating the crankshaft, and a coupling unit which is torsionally rigid in a plane generally perpendicular to the axis of the crankshaft but is readily deformable in other planes to accommodate misalignment, for connecting the drive unit to the crankshaft.
