近年來由於石油短缺，再生能源如風力發電與海流發電為現今尋找替代能源的重要課題。在風力發電與海流發電中，齒輪變速箱是系統中關鍵機構，它其主要功能為增加系統中的旋轉速度以供發電機發電。然而，因為外界的動力來源隨時間變化，使得葉輪為一變轉速輸入源，為提高發電效率希望可以得到固定頻率的輸入來維持發電品質。首先，本次研究從齒輪變速箱著手，合成一個自由度為2 的行星齒輪恆速機構。機構中，以變轉速葉輪和另一固定轉速馬達為雙輸入源，經由本機構得到一固定轉速的輸出源供給發電機作發電用。最後，再架設實際的行星齒輪系恆速機構，從實驗中觀察實際的情形以驗證理論的正確性。

In current years, searching for substitute energy such as the wind and ocean power of renewable energy is an important subject due to the petroleum shortage. The gear box is the key mechanism in the system of
wind and ocean power. Moreover, the main function of the system is to generate electricity by speeding up the rotative velocity. However, the power of environment changes momentarily and makes the turbine a variable input. In order to improve the efficiency of generating electricity, it should get the constant input to keep the high quality of generating electricity. First of all, the study focuses on the gear box and synthesizes a constant speed mechanism of planetary gear train which degrees of freedom is two. In the mechanism, inputs are the variable speed turbine and a constant speed motor. When they input the mechanism, a constant speed output will be made to supply the generator. Secondly, it is necessary to set up the real object of the constant speed mechanism of planetary gear train. Finally, observing the real condition from the experiment to prove the theory is correct.
