Estimating Hobbing Times : Gear Technology .

Hobbing is a continuous gear generation process widely used in the industry for high or low volume production of external cylindrical gears. Depending on the tooth size, gears and splines are hobbed in a single pass or in a two-pass cycle consisting of a roughing cut followed by a finishing cut. State-of-the-art hobbing machines have the capability to vary cutting parameters between first and ...

Nitriding Of Gears – By David Pye | The Monty

Gears have nitrided for many years, yet the subject of nitriding of gears is still very controversial, and continues to be so. The process of nitriding is in reality, process technology. Meaning that it is becoming very a favored thermal process technique due to the low process temperature required and no quenching.

Polish Grinding of Gears for Higher Transmission ...

These gears have both been produced by the generating-grinding method, with the gear on the right having been polished by the resin-bonded section of a two-zone threaded grinding wheel. The surface roughness of the polish-ground gear has been substantially reduced, therefore, it would cause less friction in the transmission and, consequently, would offer increased load-carrying capacity and a ...
