Title: Radial roller bearing with oil-bath lubrication
Inventor: FUEHRMANN JOERG DIPL ING
IPC: F16C33/66
Filed: 1982-10-16
Abstract: In a radial roller bearing with oil-bath lubrication, in particular for bearing rotating drums, when the outer ring (3) rotates, the oil is distributed by centrifugal force as a thin oil ring over the bearing circumference and hence prevents adequate lubrication. In order to avoid this, the oil is guided into a non-rotating chamber (10), adjacent to the roller bearing, using the static pressure which occurs in the oil ring, where it flows out downwards and is there offered to the bearing at the required level. In order to accelerate the oil circulation, the chamber (10) (adjacent to the roller bearing) of the one annular space is connected to the other annular space by means of at least one oil return channel (16). <IMAGE>
