Abstract
The invention relates to the technical field of washing machines, and in particular relates to a supporting device for a pulley of a decelerating clutch of a washing machine. In the supporting device, the pulley is supported on a clutch shaft through a rolling bearing and is connected with an input shaft in a floating manner so that the input shaft only bears rotation moment rather than tensile force of the pulley; a clutch flange is concentrically arranged on the upper end of the pulley and outside the clutch shaft, and the pulley and the clutch shaft are connected by a screw or a rivet; and the outer diameter of the upper end of the clutch flange is equal to that of the middle part of the clutch shaft, and the clutch flange and the clutch shaft are jointly inserted into a clutch torsion spring. Therefore, the supporting device has the beneficial effects that the input shaft does not generate bending stress resulting from cantilever support formed by the pulley fixedly arranged in the conventional washing machine so that the rolling bearing is not easily worn and has small noise, thus prolonging service life of the washing machine; and axial assembling clearance between the upper end face of the clutch flange and the lower end face of the clutch shaft can be randomly adjusted so as to lower manufacturing cost and facilitate assembly.
