Abstract
A ball balancing arrangement for a wash drum (14) rotatable about an axis (18) in a laundry washing machine comprises at least one closed annular path (22) which is concentrically disposed with respect to the axis (18), adapted to rotate in synchronism with the wash drum (14) and containing a plurality of moveable ball-shaped balancing bodies (23) which are kept together in groups by a corresponding number of retaining means (34) of a shape so as to keep the ball-shaped balancing bodies (23) in each group (A, B, C) out of contact with one another. Each retainer means (34) is of a design so as to have a negligible weight relative to the weight of the balancing bodies and the surfaces (38, 39, 40, 41) of the retaining means (34) bearing against the balancing bodies (23) have a low friction.
