The invention relates to a device for supplying the bearings of high-speed ones Both ends closing end walls having hollow shafts, which through a central opening in one of the end walls liquid lubricant is supplied, which is under the action of the Centrifugal force distributed over the inner wall of the shaft and provided in the area of the lubrication points radial bores reaches the bearings, with the one opposite the lubricant inlet opening End wall of the shaft a central vent hole is provided and in the shaft in the area the lubricant inlet opening a the entered lubricant in the direction of rotation of the Shaft compelling and dissipating towards the inner wall, running in the axial direction of the shaft Facility is used.

In such devices, the vent hole provided in one end wall prevents an excessively high pressure increase that may impair the introduction of lubricant into the hollow shaft due to excessive enrichment of the lubricant-air mixture in the center of the shaft while through the deflection of the lubricant associated with defoaming in the area of the lubricant inlet opening towards the inner wall of the hollow shaft, an enrichment of the lubricant-air mixture is counteracted from the outset.

In a known device, the deflection device consists of a curved S-shape Wall with angled little shovels. This device has the disadvantage that after exceeding a certain speed a blocking effect with respect to the lubricant flow through the Wave arises, apparently caused by the overlapping of the lubricant inlet opening the baffle and the curved small blades, which in themselves have no conveying effect may have bent due to the lack of a relative movement between the shaft and the S-shape Wall.

The invention is based on the object of providing a lubricating device of the type mentioned at the beginning train that besides the compound of excessive lubricant enrichment of the air core a speed-dependent lubricant supply in the shaft is ensured within the shaft and the lubricant is properly forced and centrifuged in the direction of rotation of the shaft. This object is achieved in that the lubricant in the direction of rotation of the Shaft compulsory device made up of two under one lubricator

walls running at an acute angle to each other, between which the lubricant inlet opening is located.

In the lubricating device according to the invention, a remains when the operation is started The rotating central air core, which forms the exposed lubricant inlet opening, is not fissured exist, and the lubricant delivery is always ensured regardless of the speed. In addition, will the lubricant is properly forced into the direction of rotation of the shaft and defoamed intensively.

The central venting of hollow shafts through which lubricant flows has also been proposed in connection with a transfer part for a liquid-tight connection two flush mounted at a distance from each other, each provided with a central hole and with each other coupled shafts, the transition part between the two shafts as an easily removable, working in a manner known per se according to the centrifugal principle and the lubricant Defoaming filter is formed, via which the lubricant, coming from a shaft, to reaches the bearings of the other shaft.

In the drawing, an embodiment of the invention is shown as an example.

Fig. 2 shows an enlarged section along the line II-II in Fig. 1.

In the drawing, the hollow shaft is denoted by 1, the bearing points to be supplied with lubricant by 2 and 3, the two end walls of the shaft by 6 and 7, the lubricating oil inlet opening in the end wall 6 by 8 and the central vent hole in the other end wall by 9. The hollow shaft is supplied with the lubricant from an elevated tank 10 via a line 11 protruding into the lubricant inlet opening 8 with play. in the

Claims (1)

The area of the lubricant inlet opening 8 is the lubricant immediately after it emerges from the Arranged opening to the inner wall of the hollow shaft deflecting device, which can be seen in Fig. 2 lets, consists of two walls 12 and 13 extending at an acute angle α to one another, which the lubricant inlet opening 8 tangent and in the axial direction of the hollow shaft 1 to just before the to the lubrication point 2 leading radial bores 4 extend. That out of the container during operation 10 in the hollow shaft 1 flowing lubricant is immediately after entering the shaft forced through the walls 12 and 13 to the inner wall of the shaft and forms one over there the holes 4 and 5 of the two bearings 2 and 3 extending film. In the center of the wave A rotating air lubricant core is formed, but its lubricant content is low is due to the intensive defoaming of the lubricant by the baffles 12 and 13. A is not permitted high pressure increase within the hollow shaft 1 is through the central vent hole 9 in the Front wall 7 prevented. Claim: Device for supplying the bearings of high-speed running at both ends final End walls having hollow shafts, which through a central opening in one of the End walls liquid lubricant is supplied, which is under the action of centrifugal force Distributed over the inner wall of the shaft and provided in the area of the lubrication points radial bores reaches the bearings, in which the lubricant inlet opening opposite End wall of the shaft provided a central vent hole and into the shaft in the area of the lubricant inlet opening, the lubricant that has entered in the direction of rotation the shaft, which is mandatory and which dissipates towards its inner wall and runs in the axial direction of the shaft, is used, characterized in that the lubricant in the direction of rotation of the shaft (1) Mandatory device consisting of two at an acute angle (α) to each other Walls (12, 13), between which the lubricant inlet opening (8) is located.
