  • 本研究為具浮動油腔環之液靜壓軸承系統設計與精進。具浮動油腔環之液靜壓軸承系統包含主軸、浮動式油腔環、液靜壓軸套、負載系統、量測系統與供油系統等。當主軸受到一負載時,透過浮動油腔環之構造產生與主軸偏移方向之反向位移,將主軸回推以減少主軸位移量。
    本研究著重在液靜壓軸承部件的設計與改進,目的為改善並優化前人設計之軸承,同時藉由理論分析與模擬輔助軸承設計,最後透過實驗以驗證軸承性能之提升程度。


    This research is about the design and improvement of hydrostatic bearing system with a floating ring. The bearing system includes a shaft, a floating ring, a bearing sleeve, a loading system, a measure system and an external oil system. When the shaft receives a loading, the floating ring will move in the opposite direction of the force, pushes the shaft back and reduces the displacement of the shaft.
    This research mainly focuses on the design and improvements, in order to improve and optimize the bearing system which was designed previously. The design the bearing is analyzed by theoretical analysis and simulations. Finally, experiments are performed to verify the improvement of bearing performance.
