Abstract
A bearing assembly for a rotary shaft machine, the assembly comprising a ball or rotary bearing mounted between a bearing support and the shaft, the bearing comprising an outer ring and an inner ring between which rolling elements are interposed, the outer ring being held rigidly to the support, the inner ring and the shaft being slidable relative to each other, the bearing assembly further comprising at least one washer mounted between the inner ring and a shoulder of the shaft and exerting force between the inner ring and the shoulder tending to move them apart to take up operating slack, wherein the washer presents a flat annulus and a plurality of trapezium-shaped resilient tabs extending radially from the annulus, each presenting a portion that is inclined relative to the plane of the annulus and each being terminated by an end flat parallel to the plane of the annulus.
