貝得電機(jī)教大家如何給電機(jī)軸承加油

貝得電機(jī)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(dāng)。但是,這只能是在電機(jī)嚴(yán)格按照本樣本中規(guī)定的技
術(shù)數(shù)據(jù)運(yùn)行。
對于以規(guī)定間隔再潤滑的電機(jī),軸承壽命可以延長,從
而補(bǔ)償不利因素,諸如溫度、安裝條件、轉(zhuǎn)速、軸承規(guī)
格和機(jī)械載荷造成的影響。
當(dāng)電動機(jī)在非正常的條件下運(yùn)行時,軸承的壽命會縮
短。如下面幾種情況:
■ 當(dāng)電動機(jī)的運(yùn)行速度高于額定速度時,由于電動機(jī)的
振動增大,使得軸承受到額外的徑向力和軸向力,導(dǎo)
致其壽命減少;
■ 當(dāng)環(huán)境或設(shè)備等因素引起電動機(jī)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(dǎo)致其壽
命減少;
■ 當(dāng)環(huán)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.
