Abstract

"ARRANJO DE ACIONAMENTO PARA UMA MáQUINA LAVADORA DE ROUPAS". Do tipo que compreende um tanque (10) ; um cesto (20 ) ; um eixo tubular (30 ) vertical, inferior e rotativamente mancalizado em uma estrutura (E) ; um eixo central (40 ) rotativamente mancalizado no interior do eixo tubular (30) e tendo um extremo superior (40b) carregando um impulsor (50) e um extremo inferior (40a) rotativamente acoplado a um motor elétrico (60) . O arranjo de acionamento compreende: uma mola helicoidal (80) montada em torno do eixo tubular (30) e do eixo central (40), acoplando-os em uma operação de centrifugação da máquina; uma luva cilíndrica (90) rotativamente mancalizada na estrutura (E) em torno da mola helicoidal (80) e sendo rotativamente fixada a um extremo inferior (81) dessa última; uma cinta de frenagem (95) apertadamente montada em torno da luva cilíndrica (90) e tendo uma condição inoperante, na qual libera a luva cilíndrica (90) para girar em conjunto com a mola helicoidal (80) e com os eixos tubular (30) e central (40 ) na operação de centrifugação, e uma condição operante, na qual tem seu giro bloqueado no referido sentido, bloqueando o giro da luva cilíndrica (90) e da mola helicoidal (80), de modo a desacoplar rotativamente os eixos tubular (30) e central (40); e um dispositivo atuador (100) seletivamente acionado para alterar as condições operante e inoperante da cinta de frenagem (95)."DRIVE ARRANGEMENT FOR A CLOTHING WASHER". Of a kind comprising a tank (10); a basket (20); a lower, rotatably upright tubular shaft (30) in a frame (E); a central axis (40) rotatably biased within the tubular axis (30) and having an upper end (40b) carrying an impeller (50) and a lower end (40a) rotatably coupled to an electric motor (60). The drive arrangement comprises: a coil spring (80) mounted around the tubular axis (30) and the central axis (40), engaging them in a machine spin operation; a cylindrical sleeve (90) rotatably biased in the frame (E) around the coil spring (80) and being rotatably fixed to a lower end (81) thereof; a braking strap (95) tightly mounted around the cylindrical sleeve (90) and having an inoperative condition in which it releases the cylindrical sleeve (90) to rotate together with the coil spring (80) and tubular shafts (30 ) and central (40) in the centrifuging operation, and an operative condition, in which its rotation is blocked in said direction, blocking the rotation of the cylindrical sleeve (90) and the coil spring (80), in order to disengage the axes tubular (30) and central (40); and an actuator device (100) selectively actuated to alter the operating and inoperative conditions of the braking belt (95).
