摘要:	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。本計畫為三年連續性計畫之第三年研究計畫。此一整體計畫係針對無法達成長接觸斑的錐形齒輪傳動，以齒面修整方法並配合移位嚙合的設計觀念，提出增強錐形齒面承載能力新的設計方案，同時亦嘗試解決傳統凹面錐形齒輪在直進式研磨法時磨輪直徑過小所造成齒面非赫茲接觸之問題。本年度計畫將針對前兩年成果進行齒面疲勞實驗，以驗證計畫構想、分析結果之可行性。計畫中將利用自行設計與製作之實驗設備，進行齒面（點蝕）強度疲勞實驗。測試結果並將與有限元素分析結果加以比較。同時亦會提出錐形齒輪齒面修整最佳化設計模式。本計畫最後會將此驗證可行之錐形齒輪重負載齒面修整設計模式，納入多年來所發展的錐形齒輪計算分析程式中。 ; Because conical involute gears have various advantages, such as 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 surface durability due to point contact while in meshing. This project belongs to the three-year project, which is to study how to enhance the surface durability of conical gear drives through combination of the concepts of “tooth flank modification” and “profile-shifted transmission”. The study can also solve the non-Hertzian contact problem of the concave conical gear sets generated by the in-feed grinding method with a smaller grinding wheel. Those results from the first two year of the project will be simulated and validated in the proposed third-year project (2009) through experiments. The main works in this phase are (a) design and manufacturing of the test rig and the corresponding gears, (b) surface durability (pitting) test, (c) optimal design of the flank-modified conical gear sets. The test results will be also compared and analysis with the FEA results. The verified design approaches for tooth flank modification of conical gear drives will be also converted into an interactive computer program in this project. ; 研究期間 9808 ~ 9907
