Balance ring system on two planes for a spin rotary machine

Abstract

A textile washing machine has a rotary basket balanced in at least one of its two planes, where optionally a first balance ring is structurally formed at the lower part of the basket or bottom of basket in order to balance the lower plane of the rotary basket and/or optionally, a second balance ring structured at the upper part of the basket. The first balance ring comprises: a channel or track that forms an integral part with the bottom of basket, a viscous drag fluid lodged in the track, a plurality of spheres lodged in the channel or track, immerse in the viscous drag fluid, and a lid that seals hermetically against the track. The lid comprises at least one radial rib in order to provide the bottom of basket with a structural reinforcement so that the bottom of basket does not weaken due to the presence of the track or channel. The second balance ring includes: a base with a first wall and a second wall, a cover that closes the base and with the same walls of the base, a working fluid lodged in the base, at least a curved blade lodged in the base where the blade covers from the first wall of the base and leaves a clearing between the blade and second wall, allowing the working fluid to have a vertical component; and at least a straight blade lodged in the base and alternated with the at least one aforementioned curved blade.
