漸開線錐形齒輪由於具有可控制傳動背隙、可多樣組合、組裝誤差敏感度低、加工容易等優點，為一應用場合廣大之特殊空間齒輪。但由於在空間齒輪機構組合之嚙合型態多為點接觸，因此齒面承載能力不足，從而限制其在動力傳動的發展。本計畫為期3 年將對提昇錐形齒輪齒面承載能力之課題以系統化方式進行研究，以解決無法應用在重負載傳動之問題。本年度計畫共有兩項主要研究主題： (1) 建立平行軸錐形齒輪對齒面負載分佈之計算模式； (2) 提出歪斜軸錐形齒輪對重負載傳動之設計模式，並建立受負載齒面接觸分析方法。其中齒面負載分佈之研究將以剛度法配合有限元素法，求解齒面負載分佈。而透過齒輪對的特殊設計，可以使歪斜軸錐形齒輪對齒輪嚙合為近似線接觸型態，以提昇齒面承載能力。同時計畫亦將發展出受負載齒面接觸分析方法，以瞭解對歪斜軸錐形齒輪對在近似線接觸狀況下，組裝誤差對傳動誤差與齒面接觸應力之影響。 Because conical involute gears have ability of backlash control, variety of spatial combination, mounting errors absorption and simple manufacturing, they become an important gear drive of precision transmission. However, the conical gear drive is restricted in application to power transmission because of less load capacity in surface durability due to point contact while in meshing. This three-years project will focus on the improvement of the load capacity of surface durability. The first year project has two topics: (1) Calculation of load distribution of conical gear pair with parallel axis; (2) Geometrical design of skewed conical gear pair for high power transmission, and developing a loaded tooth contact analysis method In this project, the load distribution will be calculated by using the stiffness method and FEM. In order to meet the requirement of power transmission, the skewed conical gear pair will be designed with approximate line contact. The influence of mounting errors on transmission error and contact stress will be also studied by applying the loaded tooth contact analysis method developed in this project. 研究期間：9308 ~ 9407
