Abstract

Speed variator with variable diameter pulley, particularly for washing machines for adjusting the rotation action of the drum to the various washing and centrifugation speeds. Variator comprising a drive pulley 26 and a driven pulley 27 associated with the drive motor 24 and drum 23 of the machine and connected by a transmission V belt 25. The drive pulley 26 is of variable diameter and is formed by half sheaves 28, 30, 32 cooperating with each other, in which centrifugal masses 36 are housed and which expand radially or do not to vary the diameter of the drive pulley and therefore the speed ratio, which masses are indissolubly joined by a compression spring 56 which causes their contemporary displacement to the various working positions. The solution reduces the noise and vibration of the machines. <IMAGE>
