ABSTRACT:
An arrangement for cooling a bearing assembly. The arrangement includes a drum assembly having (i) a drum member having an interior sidewall, (ii) a first bulkhead secured to the interior sidewall, (iii) a second bulkhead secured to the interior sidewall, (iv) an interior cavity defined by the interior sidewall, the first bulkhead, and the second bulkhead, (v) a drive plate secured to the drum member, (vi) a planetary gear box secured to the drive plate, and (vii) a drive motor mechanically coupled to the planetary gear box such that actuation of the drive motor causes the drum member to rotate around a central axis thereof. The arrangement also includes a first bearing assembly positioned within the interior cavity. The arrangement further includes a first dipping member having a first dipping cavity defined therein. The first dipping member is positioned within the interior cavity, wherein when a first volume of cooling liquid is positioned within the interior cavity, rotation of the drum member around a central axis thereof causes (i) the dipping member to be advanced through the first volume of cooling liquid such that a second volume of cooling liquid is captured within the dipping cavity and (ii) the second volume of cooling liquid to be poured out of the dipping cavity such that the second volume of cooling liquid contacts the bearing assembly. An associated method of cooling a bearing assembly.
