ABSTRACT:
The invention provides a radial friction bearing assembly, particularly for rotatably mounting the rolls of a paper or textile material processing machine, which will give a stable rotational movement without any vibrations and ensures that always an uninterrupted lubrication film is available, even at very low rotational speeds. A preferred embodiment of the bearing assembly comprises a stationary shaft member and an annular sleeve member rotatably mounted on the shaft member. The latter one comprises on its outer surface a plurality of equidistantially arranged longitudinal grooves which extend parallelly to the axis of the shaft member. A plurality of trapezoidally shaped recesses or pockets, having a substantially smaller depth than the longitudinal grooves, extend from and communicate with said grooves, the base edge of the trapezoid adjoining the leading edge of the longitudinal grooves. Between two adjacent recesses or pockets, a circumferential annular groove is provided which communicates with all longitudinal grooves. A lubricant, preferably water, is fed to the longitudinal grooves and circulates therein as well as in said circumferential grooves, said recesses and in a gap provided between the stationary shaft member and the rotating sleeve member.
