FIELD: textiles, paper.SUBSTANCE: washing machine (1) comprises a drum (3), a motor (6) with an output shaft (8), a driving belt (13) covering the output shaft (8) and the drum (3) for rotating the drum (3) around the first fixed axis (4), and a tensioning device (14) for the belt (13) tension, which comprises a pulley (15) loosely mounted on the second fixed axis (17) with the possibility of contact with the belt (13) with a given contact pressure and with the possibility of radial elastic deformation.EFFECT: simplification of the design of the belt drive due to elimination of the number of components while ensuring the maintenance of the belt tightly tensioned. |
