        貝得電機教大家如何給電機軸承加油

        貝得電機潤滑脂壽命和再潤滑周期
        對于不可再潤滑的軸承,其潤滑脂壽命與軸承壽命相
        當。但是,這只能是在電機嚴格按照本樣本中規定的技
        術數據運行。
        對于以規定間隔再潤滑的電機,軸承壽命可以延長,從
        而補償不利因素,諸如溫度、安裝條件、轉速、軸承規
        格和機械載荷造成的影響。
        當電動機在非正常的條件下運行時,軸承的壽命會縮
        短。如下面幾種情況:
        ■ 當電動機的運行速度高于額定速度時,由于電動機的
        振動增大,使得軸承受到額外的徑向力和軸向力,導
        致其壽命減少;
        ■ 當環境或設備等因素引起電動機振動加大時,同樣軸
        承也會因此受到額外的徑向力和軸向力,而導致其壽
        命減少;
        ■ 當環境溫度每升高 10oC,潤滑脂壽命以及再潤滑時
        間縮短一半。

        Grease life (Horizontal installation)
        Grease life and re-greasing interval
        For permanent lubrication, the bearing grease lifetime is
        matched to the bearing lifetime. This can, however, only
        be achieved if the motor is operated in accordance with the
        catalog specifications.
        For motors which can be regreased at defined regreasing
        intervals, the bearing lifetime can be extended and/or
        unfavorable factors such as temperature, mounting conditions,
        speed, bearing size and mechanical load can be compensated.
        ■ When motor runs beyond the rated speed, the increase of
        motor vibration will result in the extra radial and axial
        force on bearing. This will reduce the life of bearing;
        ■ When the motor vibration increase due to the environment
        or other equipment, the bearing also will endure more
        radial and axial force. This also will reduce the life of
        bearing;
        ■ If the coolant temperature is increased by 10 oC, the grease
        lifetime and regreasing interval is halved.
