As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a belt pulley 1 for use in a clothes processing apparatus, which may be a drum washing or drying machine or a pulsator washing machine, and the belt pulley 1 is connected and fixed with a washing tub of the clothes processing apparatus, and then the belt pulley 1 is connected with a driving member under the connection of a transmission member such as a belt or a chain. Thus, the driving member drives the belt pulley 1 to rotate, so that the washing tub can also rotate to realize a corresponding laundry treatment function. Also, since it is difficult to ensure uniform distribution of the mass of the laundry placed in the washing tub in actual use, particularly in the drum washing machine in which the washing tub is horizontally placed, it is difficult to uniformly distribute the laundry placed in the washing tub, resulting in concentration of the weight at the bottom. Under the condition that the clothes in the washing barrel are unevenly distributed in quality, when the driving piece drives the washing barrel to rotate, the washing barrel rotating at a high speed can generate unbalanced force, so that the washing barrel is unbalanced in rotation, noise is generated, and the phenomenon that the washing barrel generates overlarge noise in the operation process is caused. Therefore, in order to reduce the problem of excessive noise caused by the unbalanced force generated by the operation of the washing tub, the embodiment of the present invention provides the above-mentioned belt pulley 1 to play a role of reducing the unbalanced force generated by the operation of the washing tub, and reduce the noise generated by the operation.

As shown in fig. 1 and 2, the pulley 1 comprises a sheave 11 and a balance assembly 12. The wheel disc 11 is used for being fixedly connected with a washing barrel of the clothes processing device, and meanwhile, the wheel disc 11 is used for receiving the rotating force of the driving piece and transmitting the rotating force to the washing barrel, so that the washing barrel can obtain the rotating force to rotate synchronously. An accommodating cavity is formed in the wheel disc 11, and the balancing assembly 12 is slidably arranged in the accommodating cavity of the wheel disc 11, so that the balancing assembly 12 can move in the area of the accommodating cavity without being limited to a specific position. The balancing assembly 12 is used for adaptively adjusting the position in the wheel disc 11 according to the stress condition of the balancing assembly when the wheel disc rotates, so as to counteract the unbalanced force generated when the washing tub rotates. Specifically, be provided with balanced subassembly 12 through adopting at rim plate 11 internalization, thereby, when rim plate 11 drives the washing barrel high-speed rotation, the uneven power that the inhomogeneous washing barrel of internal mass operation produced transmits rim plate 11 on, according to the rotor dynamics theory, balanced subassembly 12 in rim plate 11 is after through critical speed, according to the atress condition, balanced subassembly 12 can move to the opposite face of unbalanced mass voluntarily, thereby offset off-centre, reduce the produced unbalanced force of unbalanced mass, make the washing barrel can keep the state operation of atress balance, and then reduce the produced noise of the unbalanced motion of washing barrel, make washing barrel moving in-process can not produce great noise, promote the transport nature of in-service use.

The utility model discloses the belt pulley that provides in implementing adopts ingeniously to be provided with balanced subassembly 12 in the rim plate, thereby when 11 rotations on the rim plate, balanced subassembly 12 just can be according to the atress condition of self, the position of self-adaptation adjustment in 11 rim plates, the opposite face of unbalanced mass is arrived in the automatic sliding, reduce the produced unbalanced force of unbalanced mass by the washtub, thereby offset off-centre, make the washtub can steady operation, just can reduce the produced vibration noise of complete machine operation by a wide margin, the operation noise is low, use the travelling comfort good.

As shown in fig. 2 and 3, in a possible embodiment, pulley 1 further comprises an annular slide 13, annular slide 13 being arranged in sheave 11, and balancing assembly 12 being slidingly arranged in annular slide 13. That is, an annular slide 13 is provided at a suitable location inside the wheel disc 11 according to design requirements, and the balance assembly 12 is defined within the annular slide 13. Therefore, the movement position of the balance assembly 12 arranged in the wheel disc 11 can be partially limited, the movement direction of the balance assembly 12 is guided, the position of the balance assembly 12 can be orderly and rapidly adjusted, and the position of the balance assembly 12 which can counteract unbalanced force can be rapidly adjusted. Specifically, since the wheel disc 11 is circular, it is preferable to keep the central axis of the annular slide 13 coaxial with the central axis of the wheel disc 11, and the annular slide 13 is circumferentially arranged according to the shape of the wheel disc 11 so that the balance assembly 12 can perform selection of the balance position at various positions in the circumferential direction along the annular slide 13.

Of course, it will be understood that the balancing assembly 12 may also be configured to include a slider that is slidable within the receiving cavity or the annular track 13, if the requirements of use are met.

In a possible embodiment, the balancing assembly 12 further comprises a layer of lubricating oil arranged inside the annular slide 13, the balls 121 being at least partially located inside the layer of lubricating oil. Since the balls 121 are rubbed against the annular slide 13 and the balls 121 during rolling, the friction interferes with the movement and also generates noise. Therefore, by providing the lubricating oil layer, at least a part of each ball 121 is located in the lubricating oil layer, which not only can play a role of lubrication, but also can reduce the friction force, so that each ball 121 can move smoothly. Moreover, by the isolation of the lubricating oil layer, the abnormal noise generated by the movement of each ball 121 can be reduced, and the design ingenuity is good. Specifically, the amount of the lubricant layer provided in the annular slide 13 is preferably about 50% of the volume of the annular slide 13.

As shown in fig. 2 and 3, in one possible embodiment, the wheel disc 11 includes a disc body 111 and a disc cover 112. The tray body 111 is provided with a connection structure 113 connected with the washing tub, and the washing tub is fixedly connected with the wheel disc 11 through the connection structure 113.
