ABSTRACT:
A foil sliding bearing for machines, in particular a foil sliding bearing for glandless rotary and centrifugal pumps used in chemical processes, such as for pumping corrosive liquids, and adapted to be lubricated by the liquid being pumped (centrifugal pumps, gap-tube pumps, and the like) is provided. This bearing comprises a bearing sleeve to be positioned between a bearing pin or a shaft and a coaxial cylindrical or slightly conical bearing housing of the machine. Around the outer periphery of the bearing sleeve a plurality of plastic foil sections are held at their front ends each, as seen in the direction of rotation, in axial slots formed in the bearing sleeve and which do not extend up to the edges, and at their rear ends they lie loosely on the outer bearing sleeve and leave an expansion gap free with respect to the adjacent foil sections. The sliding clearance between the foil sections and the bearing surface of the bearing housing is greater than in conventional sliding bearing and is dimensioned to about 0.3 to 1 mm.
