Device for lubricating the bearings of a rotating shaft

摘要

The oil pump (8) is placed to one side of the annular reservoir (14) containing a pool of oil (18). It delivers oil (20) to a distribution cone (22) at the end of the shaft. The ball- or roller-bearing (5) for the shaft (3) is lubricated by oil flung off the large end of the cone. The oil may flow back to the reservoir through channels (24-27) in the bearing and oil reservoir housing (1). A large diameter cone (28) above the bearing slings any oil that gets through the bearing into the upper oil return channels. The pump has oppositely threaded spindles (10,11) to help feed oil into it from its upper or lower end.
