Description

Technical Field

[0001] The utility model belongs to the technical field of washing machines, and particularly relates to a shock absorbing structure of a clutch of a dual-power washing machine. Background Art

[0002] A dual-power washing machine is a washing machine with special technology. It applies reverse forces to the impeller and the inner drum at the same time, making both rotate in opposite directions at the same time, thus forming a three-dimensional water flow.

[0003] A Chinese patent with announcement number CN104452169B discloses a dual-power washing machine deceleration clutch and a washing machine thereof, which relate to the technical field of washing machines, and include a dehydration shaft, a pulsator shaft, a mounting plate and an input shaft, wherein the pulsator shaft is concentrically mounted in a hollow dehydration shaft, the dehydration shaft is mounted in the mounting plate through a bearing and an oil seal, the input shaft is connected to an external power source, and the input shaft is connected to the dehydration shaft and the pulsator shaft through a layer of deceleration mechanism; the layer of deceleration mechanism includes an input shaft gear disposed at the top end of the input shaft, the input shaft gear is meshed with a planetary gear, the planetary gear is meshed with an internal gear, and the internal gear is connected to the pulsator shaft through a transmission plate; an external gear is disposed on the outer periphery of the internal gear, the external gear is mounted on a planetary carrier and meshed with an outer internal gear through an outer planetary gear.

[0004] The above technical solution has the following defects: the dehydration shaft of the deceleration clutch is installed in the mounting plate through two bearings and an oil seal. The two bearings divide the dehydration shaft into two parts, resulting in the two parts of the dehydration shaft vibrating separately under the dehydration condition, thereby causing the wear of the parts in contact with the dehydration shaft to increase. The gap between the dehydration shaft and the contact parts will gradually increase. The increase in the gap will further aggravate the vibration, because a larger gap means less support and worse stability. The vicious cycle leads to poor stability of the overall structure.

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] Embodiment 1:

[0022] A shock absorbing structure for a clutch of a dual-power washing machine, such as Figure 1 As shown, it includes a clutch housing 1, a mounting plate 2, a dehydration shaft 3, a pulsator shaft 4 and a fixing member 5. The dehydration shaft 3 is hollow and the pulsator shaft 4 is coaxially arranged inside the dehydration shaft 3.

[0023] The dehydration shaft 3 is installed in the mounting plate 2 through a bearing 6. A water seal 10 is provided between the dehydration shaft 3 and the mounting plate 2. The water seal 10 is used to seal the dehydration shaft 3 and the mounting plate 2, thereby ensuring the sealing between the two.

[0024] A bearing 7 is arranged between the dehydration shaft 3 and the brake wheel 13. Preferably, in this embodiment, the bearing 7 adopts a 6805 bearing. Specifically, a positioning groove 12 for installing the bearing 7 is arranged in the brake wheel 13. The positioning groove 12 ensures the position of the bearing 7 and ensures the stability of the bearing 7.

[0025] A bearing three 8 is provided in the fixing member 5, and the bearing three 8 is located between the brake wheel 13 and the fixing member 5. Preferably, in this embodiment, the bearing three 8 adopts a 6808 bearing. Specifically, a mounting groove 9 for mounting the bearing three 8 is provided on the fixing member 5. The mounting groove 9 ensures the position of the bearing three 8 and ensures the stability of the bearing three 8.

[0026] The fixing member 5 is connected to the clutch housing 1 . It should be noted that the fixing member 5 can be connected to the clutch housing 1 by screws.

[0027] It should be noted that, during normal operation, the vibration is first transmitted to the fixing member 5, and then transmitted to the clutch housing 1 through the fixing member 5. It should be further noted that, since the clutch housing 1 is relatively large in size and has good rigidity, it can effectively absorb and disperse the vibration.

[0028] The fixing member 5 is provided with a through hole 11 , through which the brake wheel 13 passes. The through hole 11 is opened along the central axis direction of the fixing member 5 , and the brake wheel 13 is avoided by opening the through hole 11 .
