Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing parts technology, specifically a wave-shaped gasket and a washing machine clutch. Background Technology

[0002] A wave-shaped shim is a shock-absorbing damping component, consisting of a wavy, undulating ring, commonly used to reduce the axial reciprocating movement of a shaft. Because the rotation of the shaft can cause the wave-shaped shim to rotate, it can rub against other parts, resulting in wear. In harsh environments, the worn areas of the wave-shaped shim are prone to corrosion, leading to elastic failure. Therefore, it is necessary to improve the structure of the wave-shaped shim. Utility Model Content

[0003] One technical problem to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide a wave-shaped gasket and a washing machine clutch using the wave-shaped gasket, which can reduce axial movement and is more wear-resistant.

[0004] The technical solution adopted by this wave-shaped gasket to solve the technical problem is as follows: a wave-shaped gasket includes a wave-shaped gasket body, wherein the wave-shaped gasket body is covered with a wear-resistant material layer.

[0005] Compared with related technologies, this corrugated gasket has the following advantages: the corrugated gasket body is wrapped with a wear-resistant material layer, which can reduce axial movement and, by wrapping and blocking the corrugated gasket body, can prevent the corrugated gasket body from being worn and corroded, thus better ensuring the elasticity of the corrugated gasket body and having a longer service life in harsh environments.

[0006] As an improvement, the arc shape of the wear-resistant material layer matches that of the corrugated gasket body. This ensures good adhesion and avoids uneven injection molding that could lead to a weak bond between the two materials.

[0007] Preferably, the thickness of the wear-resistant material layer is the same as the thickness of the corrugated gasket body.

[0008] As an improvement, the wear-resistant material layer is provided with multiple blind holes for positioning the wave-shaped gaskets during injection molding, thus ensuring injection molding quality.

[0009] The technical solution adopted by this washing machine clutch to solve the technical problem is as follows: A washing machine clutch includes a clutch shaft and an input shaft. A bearing is provided between the bottom end of the clutch shaft and the input shaft. A clamp for limiting the bearing is provided on the input shaft. The teeth of the sun gear at the upper end of the input shaft are helical teeth. It also includes an elastic element for reducing the axial movement of the input shaft. The elastic element shown is the aforementioned wave-shaped washer. The wave-shaped washer is sleeved on the input shaft and abuts against the clamp and the bearing.

[0010] Compared with related technologies, this washing machine clutch has the following advantages: the added wave shim can reduce the axial movement of the input shaft, and the friction between the wave shim and the bearing and / or clamp when the wave shim rotates occasionally will not wear the internal wave shim body, thus better ensuring the elasticity of the wave shim body.

[0017] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] This embodiment is an example of... Figures 1 to 3 The wave-shaped gasket 7 shown includes a wave-shaped gasket body 7.1 made of steel, and the wave-shaped gasket body 7.1 is wrapped with a wear-resistant nylon material layer 7.2.

[0020] As an improvement, the arc shape of the outer surface of the wear-resistant material layer 7.2 is consistent with that of the corrugated gasket body 7.1.

[0021] As an improvement, to ensure the stability of injection molding quality, the wear-resistant material layer 7.2 is provided with a plurality of blind holes for positioning the wave-shaped gasket 7 during injection molding.

[0022] Waveform pad 7 is used in, for example Figure 4 and 5In the washing machine clutch shown, the clutch is a crucial component of the washing machine, used to initiate washing and spin-drying functions. It typically employs a clutch shaft, brake wheel, spin-drying shaft, and a reduction mechanism consisting of an input shaft, planetary gear train, and impeller shaft. The input shaft and planetary gear train utilize either spur gear or helical gear transmission. Spur gears have a low overlap ratio, resulting in high noise from direct engagement and low torsional torque, leading to low washing capacity. Helical gear transmission, on the other hand, has low noise due to gradual, oblique engagement and high torsional torque, resulting in high washing capacity. However, a drawback is that the input shaft can experience axial movement, causing unstable meshing between the sun gear and planetary gear train. The wave-shaped gasket 7 can reduce this axial movement. Occasionally, the input shaft 1 and the wave-shaped gasket 7 may rotate, causing friction between the wave-shaped gasket 7 and the bearing 6 and / or clamp 8. The wear-resistant material layer 7.2 prevents wear on the wave-shaped gasket body 7.1, thus better ensuring the elasticity of the wave-shaped gasket 7. The washing machine clutch includes an input shaft 1, a planetary gear system (not shown in the figure), an impeller shaft 2, a clutch shaft 3, a brake wheel 4, and a spin-drying shaft 5. A bearing 6 is provided between the bottom end of the clutch shaft 3 and the input shaft 1. A clamp 8 for limiting the bearing 6 is provided on the input shaft 1, and a bearing is also provided between the upper end of the input shaft 1 and the top end of the clutch shaft 3. Because the teeth of the sun gear 11 at the upper end of the input shaft 1 are... Figure 6 The helical gears shown, and the planetary gear system also uses helical gears, will generate axial movement during forward and reverse rotation. Therefore, an elastic element is needed to reduce the axial movement of the input shaft 1. The elastic element is preferably the aforementioned wave-shaped shim 7, which is sleeved on the input shaft 1 and abuts against the clamp 8 and the bearing 6. In addition, the dehydration transmission mechanism composed of the clutch shaft 3, brake wheel 4, and dehydration shaft 5 can be structurally adjusted according to actual needs.

[0023] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
