KOEHLER 高溫輪軸承潤滑脂試驗機 產品信息

汽車輪縠軸承用潤滑脂壽命特性測定法
      加速條件下汽車輪縠軸承潤滑脂漏失趨勢測定法

試驗方法
      本試驗方法用于評估汽車輪軸承潤滑脂在經過修改的前輪輪縠-軸-軸承組合件里的高溫穩定性。ASTM D3527壽命特性試驗采用苛刻的試驗條件-25 lbf (111N)的推力負載、1000rpm, 160°C的軸溫度-以致使潤滑脂性能降低并不適于使用。在20/4小時的on/off循環條件下繼續試驗,直至潤滑脂遭到破壞,致使所測到的驅動馬達轉矩增加到越過已確定的終點。達到不合格所需要的時間數便是試驗結果。ASTM D4290加速漏失趨勢試驗采用類似的試驗條件,20小時的試驗周期,在試驗周期過后,測量潤滑脂與油的漏失量,清洗軸承并檢查軸承上膠與漆的沉積物。

高溫輪軸承潤滑脂試驗機
• 符合 ASTM D3527, D4290 與 D4950 規格
• 全自動操作
• 所有測試功能均為數字監控

      本試驗機用于依照ASTM試驗規格來進行潤滑脂的壽命特性與加速漏失趨勢試驗。由一個經過修改的前輪輪縠-軸-軸承組合件組成,該組合件裝在一個恒溫爐里并連接到一個1/4hp的變速驅動馬達上。自動控制試驗功能并連續數字顯示馬達轉矩、rpm 、測試室溫度、軸溫、時間周期與已消逝的時間。操作者可以選擇ASTM規格以外的試驗參數以用于國內的試驗。在出現因潤滑脂性能退化而造成驅動馬達轉矩增加到經校準過的終點時,試驗機自動終止試驗并顯示消逝的時間。內裝有一個30秒時間延遲電路,以防止因在時間周期開始時馬達轉矩瞬間出現而引起的試驗錯誤終止。絕緣的恒溫爐里裝備有一個1200W 加熱器,而一個平穩的1/20hp循環扇用于提供有效的熱分布。滑動進入門與可動平臺,移開驅動馬達以便于接近與處理軸組合件。經過修改過的鋼制軸與輪縠組合件符合所以的1971 Chevy II 尺寸,并配有熱電偶、軸承推力加載裝置與鍍鋁的潤滑脂接收器。所以的控制器與監控器均封裝在一個單獨的箱體里。
