摘要

以電動車用雙檔位變速箱為研究對象，透過傳動系統分析軟體探討齒輪嚙合過程中齒輪單位長度最大負載、最大接觸應力和傳動誤差，比較齒輪修整前和修整後對於此三個性能指標之影響。分析結果為：齒輪未修整時，傳動誤差不平順且齒面負載分布於齒緣，將造成較大的嚙合衝擊，需對齒輪進行修整以改善受力情況，進而降低噪音，延長齒輪使用壽命；齒輪修整後，變速箱動態性能有所改善，齒輪受力減小，提高了齒輪的承載力和壽命。

With to the dual-speed gearbox for electric vehicles as the research object, through the analysis of the software of the transmission system, the normal load per unit length, the maximum contact stress and the transmission efficiency in the gear meshing process we discussed in this paper. The three performances before and after the implementation of the gear microgeometry are compared. The results showed that the transmission error is not smooth and the tooth surface load is distributed on the tooth edge, suggesting a large meshing impact indicating that the gears need to be modified to improve the stress conditions so as to reduce the noise and extend the service life of the gears. After the gear modification, gearbox performance is improved and the gears have less stress. The carrying capacity and life of the gears have been improved.
