抄録

To manufacture folding-less gears by hot-rolling process, the auther experimentally investigated the rolling conditions. The results or preliminary experiment by using soft materials revealed that the raise-up of the metal varied with the plasticity of the material which was to be rolled, rolling speed, and sliding action on the respective faces of the teeth at the moment of the generating motion. Applying these results to the hot-rolling of steel gears, module m=2∼3, rolling conditions such as the heating temperature, depth of the heated zone, pressing speed of the die-roller and rotating speed of the gear blank, have been obtained. The metal structure of the gear rolled hot under these conditions is satisfactory without showing any crack or folding on the rolled teeth.
