PATENT OFFICE.

The invention relates to a device for preventing the leakage of oil on bearings which are provided with a ring chamber adjoining the actual bearing.
The peculiarity of the invention consists in the fact that the annular space is either connected to a suction fan or itself forms the housing of a suction fan, so that atomized lubricating oil is discharged from this annular space.

In the drawing, two exemplary embodiments of the invention are illustrated, and although shows

Fig. Ι the one Ausführungsfonn in the Side view, partly in section.

FIGS. 2 and 3 explain the second embodiment in longitudinal section and in an end view.

α is the shaft and b is the bearing housing for the actual bearing. The ring-shaped chamber c is connected to the latter, which expediently does not completely tightly surround the shaft, but rather leaves an opening free at its point of passage between the shaft and the inner edge d. The annular chamber c encloses the known oil slinger rings e, which throw off the oil creeping along the shaft a from the bearing. This oil accumulates mostly in the trough ■ f, the appropriateness of an intermediate wall ^{Ii: t} ', is introduced. The latter separates the inner chamber ^ from the outer chamber g and prevents oil from escaping to the outside. The oil collected in the channel f is expediently returned to the store.

The oil which is atomized when the bearing is working is guided by the train into the outer annular space g and from this in the exemplary embodiment according to FIG. 1 through the to a! Blower or similar suction device leading line k derived. The oil, which has been atomized to form a mist, is thus absorbed and fed to the condenser. The air flow entering through the annular slot d also prevents oil from escaping from the annular space.

In the embodiment according to FIG. 2, an oil slinger Z is also mounted in the outer annular space g , to which suction fan blades are attached. Otherwise, the design is essentially the same as in FIG. 1. The direction of the blades is of course such that the fan thus formed sucks in air through the annular slot d and discharges the air saturated with the oil through the line k .
