流體動壓軸承

設計

流體動壓軸承(FDB)是一種全新的軸承形式,其屬於非接觸式軸承,主要應用於3C產業,最常見於伺服器及電腦所使用之散熱風扇。相較於過往所使用之迷你滾珠軸承及含油軸承,FDB運轉時能夠更加安靜及穩定。搭以東培選用之動壓油,我們的產品不僅達到最佳之壽命,同時抗振性能也有所提升。

動壓油

FDB所使用的動壓油除了提供運轉時所需之潤滑功能外,更重要的是必須維持FDB運轉時所需之壓力,使其能夠穩定運轉,不會產生額外振動及噪音。東培與世界頂尖之油品製造商合作多年,因此能向客戶推薦最適切之動壓油選用。

壽命

FDB之壽命依組立好之模組風扇置於恆溫恆濕機設定溫度為80℃、濕度65%之環境下,驗證其FDB系統於高溫與高濕環境下之壽命,並依據試驗數據,計算出FDB L10 之壽命保證係數。 以上述試驗結果進行計算,東培生產之FDB於一般產品使用工作環境溫度60℃,L10運轉週期壽命評估約100,000hrs。

軸承標稱品名

軸承的標稱品名是用以表示軸承的形式、尺寸、精度、內部構造等的一種代號,其排列順序如下:

旋轉方向 F 逆時針
H 順時針
內徑 15 1.5mm
20 2.0mm
30 3.0mm
外徑 040 4.0mm
080 8.0mm
高度 016 – 105 1.6mm – 10.5mm
特殊要求 N 正逆轉
油品 LT43
