Improved machine for grinding with grinding wheel and grinding process.

摘要

A method for grinding the crank pins (56) of a crankshaft (54) by which the machine is controlled by a computer and the grinding wheel back and forth UNDER CONTROL COMPUTER TO FOLLOW THE MOVEMENT PLANETARY crankpin as the crankshaft turns . THIS KEEPS CONTACT THE GRINDER AND GRINDING Muñequilla FOR THIS. The crankshaft is mounted between POINTS AND TURNS THE INFLUENCE OF A DRIVE UNIT (52, 46) transmitted MOVEMENT Crankshaft end THROUGH A CONNECTION (10) device which is torsionally RIGID in a plane perpendicular to the axis of rotation of the crankshaft, BUT IN OTHER PLANES easily deformable in order to accept MISALIGNMENTS and uncoupling the crankshaft (54) of the drive (52, 46), ASIDE TO TRANSMIT THE SIMPLE rotational movement to the crankshaft.
