Abstract: A laundry washing machine having an outer casing, a washing tub, a rotatable drum and at least one balancing ring rigidly secured to the rotatable drum. The at least one balancing ring includes a substantially toroidal, annular housing that is rigidly secured to the drum, and has a tubular structure so as to delimit a closed annular inner cavity. A number of balancing masses are accommodated in movable manner inside the annular inner cavity, preferably together with a damping liquid. The annular housing has a substantially frustoconical outer wall segment that is inclined by an angle (?) lower than 90° with respect to the midplane (P) of the annular housing, and a peripheral supporting structure that juts out outwardly from the substantially frustoconical outer wall segment to stably abut against the body of the drum.

Abstract: A laundry washing machine having an outer casing, a washing tub, a rotatable drum and at least one balancing ring rigidly secured to the drum for reducing vibrations thereof. The balancing ring comprises an annular housing rigidly secured to the drum, an internal closed annular inner cavity, and balancing masses in free movable manner inside the annular inner cavity. The annular housing has first and second discrete and complementary annular hemishells that are joined to one another to form the annular inner cavity. The annular hemishells are substantially coplanar and concentric to one another, and have approximately C-shaped cross sections that are substantially complementary to one another. The hemishells are joined to one another along corresponding first and second mating annular rims, which are arranged on opposite sides of a given intermediate plane perpendicular to the central axis of the annular housing.
