DISC DRIVE ACTUATOR ASSEMBLY WITH BEARING COOLING

摘要

Various aspects of the present disclosure are directed toward a disc drive actuator assembly including an e-block, a plurality of bearings, and one or more heat transfer components. The heat transfer component(s) operates to conductively draw heat from the plurality of bearings through the e-block, and convectively dissipate the heat into an atmosphere in contact therewith. The heat transfer component(s) mitigates temperature rise of the bearings during operation of a disc drive, thereby mitigating bearing lubricant outgassing from within the bearings.

主权项

1. A disc drive actuator assembly comprising:
an e-block including one or more actuator arms and a voice coil mount on a first surface; a plurality of bearings configured and arranged to facilitate rotation of the e-block around a pivot shaft; and one or more heat transfer components thermally coupled to a second surface of the e-block that is different than the first surface, and configured and arranged to mitigate temperature rise of the plurality of bearings during operation of a disc drive by conductively drawing heat from the plurality of bearings through the e-block, and by convectively dissipating the heat into an atmosphere in contact therewith.
