本研究改良現有靜動壓混合軸承,即在傳統液靜壓軸承之油腔中放置多孔材料瓦片,使軸承同時具有靜壓及動壓的性能特性以適應主軸在不同轉速下的工作情形。
本研究將基於前人所製造之多孔瓦片軸承,改善瓦片脫落與瓦片於軸承接合處的漏油情形,同時各周邊零件將會以接近真實實驗的環境進行性能量測,並發想一可拆裝瓦片的新型軸承架構,以因應未來替換不同材料瓦片的需求。
設計階段使用CAE軟體協助設計相關零件並評估軸承性能,製造完成後將於量測平台上進行實驗加以驗證並以理論計算結果比較差異。
A new type of hydrostatic-dynamic bearing is introduced in this study. By putting pads made of sintered porous material in the chambers, the new bearing remain the same performance of a traditional hydrostatic bearing at start-up and low speeds but benefits from hydrodynamic effects at high rotating speeds.
This study is based on a hydrostatic-dynamic bearing built by previous researchers. A new way to attach the pad to the bearing chamber is developed to solve the leaking problem. Related parts are tested individually under close-to experiment environments. An assembled bearing is also attempted in case the porous material needs to be changed.
CAE software is used to help designing and estimating the performance of the bearing. The bearing is tested on a platform to see its real performance and the results are compared to numerical results.
