Unlike a hobbing cutter, the shape of the knives is similar to that of a general gear. However, the cutting edge has more rake angle, head clearance angle and side clearance angle on the cutting surface, in addition to better cutting conditions, it is also convenient for repeated use. In general, a helical planer with a large helix angle is designed to have a cutting edge for cutting as a cutting surface with the cutting edge of the tool axis for the sake of accuracy. It is relatively close to its normal approach, so its tooth profile error is minimal, and its modified mathematical model can be obtained through geometric analysis of its normal close face, as provided by the early tool supplier Lorenz. However, it is necessary to perform gear grinding on the sharpening of the tool, and the sharpening efficiency is poor. In this paper, Isoform's tooth cutter is used to create the tooth surface mathematical mode. However, unlike the general spiral tooth cutter, the mathematical model of the edge line with a conical blade face is proposed, and then the relative motion is used. The coordinate transformation relationship is used to find the mathematical model of the cutter enveloping gear during the machining of the planer. According to the numerical examples in this study, the known geometric correction method of the approximate normal approach is in this case. The study's conical edge face mathematical model does not apply. Therefore, through the analysis of the tooth profile error of the tool enveloping tooth, the error ratio of the theoretical involute tooth profile and the tooth shape of the tool enveloping tooth is used to further correct the tooth profile pressure angle of the spalling blade with a conical cutting angle surface, and Under the different regrind surfaces, the tooth shape of the tool enveloping gear changes with the tooth shape of the actual created tooth shape. And the correction effect of this correction method is compared under different regrind surfaces. HUAUG, CHIN-LUNG 黃金龍 2018 學位論文 ; thesis 65 zh-TW |

碩士 === 國立虎尾科技大學 === 機械設計工程系碩士班 === 106 === In the industry today, the method of mass production of gears is mainly based on hobbing and gear processing.
