Patent application

camp

The invention relates to a bearing with an inner and an outer bearing bush set arranged concentrically therewith, in particular for railway vehicles.

In such a camp is provided according to the invention, that between the bearing bushes at least one cylindrical bearing lining is provided, which is arranged on a bushing and has a bearing surface which engages the other socket, the sockets opposite are rotatably mounted to each other.

In addition to their use in railway vehicles, there are numerous other uses instead of Wälzbzw. Ball bearings, then the outer diameter of the outer sleeve and the inner diameter of the inner sleeve in accordance with the outer and inner Diameter of the rolling or ball bearings are brought, the

be replaced by the bearings according to the invention.

The bearing lining can consist of two half-shells or a sleeve «»

Two bearing linings may be provided which are placed side by side between the sockets.

Advantageously, at least one thrust washer pointing in the axial direction is secured against axial displacement with respect to a bushing and is in engagement with an axially pointing pressure surface on the other bushing to limit the axial movement between the bushings in one direction.

Ss can be arranged on both axially facing end faces of a bushing and with the end faces of the other socket are in singriff and thus secure the bushings against axial movement.

The bearing liner can be connected to the outer sleeve and have a bearing surface that communicates with the inner Socket is engaged.

Devices for supplying lubricant to the bearing surface of the liner are advantageously provided. Appropriately, an annular oil seal is provided at at least one end of the bearing assembly, which prevents loss of lubricant. The oil seals can be at both ends of the bearing assembly between the Inside and the outer socket to be provided »

Between the bearing linings 12, annular grooves 14 and 15 are formed on the inner circumference of the bearing bushing 11 and the outer circumference of the trunnion bushing 10, which point towards one another and together form an annular channel 16 between the adjacent end faces of the linings 12 radial bores 17 in the bushing 11 in connection with an outer annular groove 18 which surrounds the bushing 11 and to which lubricant under pressure is fed in a manner to be explained in more detail below. The lubricant passes through the bores 17 into the annular channel 16 and thus lubricates the bearing surfaces of the liners "The bearing surface of each liner has a groove 20 on ₉ which runs helically over the surface of a peripheral end of the liner to the other circumferential end to the lubricant, v / ie grease or oil to be taken up from the channel 16 and to be distributed on the surface of the trunnion bushing 10.
