Title: Self-pumping thrust bearing for vertical-shaft machines, especially for water-driven generators
Inventor: POLLOK HANS-JURGEN DIPL ING
IPC: F16N9/02
Filed: 1982-09-22
Granted: 1985-10-03
Abstract: A self-pumping thrust bearing for electric machines having a vertical shaft is disclosed in which oil circulates through radially-extending bores in a rotating thrust ring to suck hot oil from an oil space and transfer it to a ring canal disposed in a stationary part. In order to make the transition from the rotating thrust ring to the stationary ring canal as loss free as possible, there is arranged on the outside at the thrust ring a circular canal into which the bores lead. This circular canal is bounded on the side facing the stationary part by a height-adjustable ring which is held at the thrust ring with a gap between the ring and the thrust ring. The transfer of oil therefore takes place around the entire circumference of the thrust ring so that turbulence is avoided. The quantity of oil pumped can be adjusted by adjusting the width of the gap.
