臺灣博碩士論文加值系統

隨著科技的蓬勃發展，機械業越來越講求精密度與可靠度，使得數值計算功能與電腦輔助製圖功能更加完備，各式加工機的設計也更精密，但國內有關非圓形齒輪的設計與分析卻相當稀少，也鮮少將非圓形齒輪應用於機台或汽機車上。因此本研究利用一對非圓形齒輪對機車引擎的活塞機構做速度平衡，根據原有之機車引擎的轉速輸出曲線進行曲線擬合，產生所需的曲線方程式，再由齒輪原理設計中的節曲線公式代入開發之visual C++程式中，並配合繪圖軟體設計出非圓形齒輪的節曲線。因節曲線是封閉的，所以周長必須為周節的整數倍，本研究利用Simpson's 1/3積分式求出中心距，並代入visual C++程式中，得到利用滾齒加工所獲得之非圓形齒輪。
本研究是根據原轉速與加裝非圓形齒輪後的轉速來進行分析，以了解加裝前和加裝後的轉速有無明顯變化，亦透過實驗平台的建置與實驗的進行，對本研究構想及成果進行驗證。

With the rapid development of science and technology, the demand of high precision and reliability of machinery industry, which pushes the numerical calculation function and computer-aided drafting function to be complete, However till now, the design and application of non-circular gears in industry is quite rare. There are few applications of non-circular gears in the machine or the internal combustion engine. Therefore, this study uses a pair of non-circular gears to balance the speed of the piston mechanism of the locomotive engine. The speed output curve is firstly curve-fitted to generate the required pitch curve equation. Then the pitch curve formula is substituted into the developed visual C++ program, and the pitch curves of the non-circular gear are designed and drawn. The pitch curves are closed, so the circumference must be an integral multiple of the circular pitch, and then the center distance is calculated by using Simpson's 1/3 integral formula. The parameters are substituted into the visual C++ program to obtain the non-circular gear obtained by hobbing.
This study is based on the original rotational speed and the corrected rotational speed after the installation of non-circular gears is investigated. Through the construction and experiment of the experimental platform, the results are verified and compared.
