ホブ切りトルクの定量化に関する研究 : 第3報, 最大ホブ切りトルクの実用式

For the strength-design of hob teeth, the decision of optimum cutting conditions and the analysis of vibrations on a hobbing machine, it is necessary to determine the maximum hobbing torques in advance. This paper presents the equation fro calculating the maximum hobbing torque for practical use, and also shows the corrective coefficients by which the specific cutting forces in orthogonal turning tests are applied to those in hobbings. Form a comparison of the calculated hobbing forces with the measured ones reported in another paper, it is confirmed that this calculating equation of the maximum hobbing torque can be used practically in the case of steel gear materials such as JIS SCM435 and SCM415.
