[0016] The above description is only a summary of the technical scheme of the present application, in order to more clearly understand the technical means of the present application, the content of the specification can be implemented, and in order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the following preferred embodiments are described in detail, and the accompanying drawings are as follows. BRIEF DESCRIPTION OF DRAWINGS

[0017] Figure 1 The structure of the present embodiment is shown in the figure.

[0018] In the figure: 1, mounting seat; 2, rotating seat; 3, bearing structure; 31, retainer; 311, groove; 32, ball; 33, elastic compression ring assembly; 331, control ring; 332, wave spring; 333, stop ring; 4, insertion sheet. DETAILED DESCRIPTION

[0019] In order to make the content of the present application more easily understood, the following will be described in detail according to the specific embodiments and in conjunction with the drawings.

[0020] It should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "inner", "outer" and the like used herein indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application. Unless otherwise stated, the meaning of "a plurality of" is two or more.

[0021] Unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0022] like Figure 1 As shown, a bearing assembly includes a mounting seat 1, a rotating seat 2 axially fixed and circumferentially rotatably connected to the mounting seat 1, a bearing structure 3 is provided between the mounting seat 1 and the rotating seat 2, and the bearing structure 3 includes a retainer 31 and a ball 32. The retainer 31 is provided with a groove 311, and the ball 32 is installed in the groove 311;

[0023] Ten balls 32 are provided, with a gap between every two adjacent balls 32, and the side of the balls 32 facing the mounting seat 1 is in the same plane. The side of the mounting seat 1 facing the balls 32 is provided with an elastic pressure ring assembly 33 to prevent the balls 32 from moving;

[0024] The elastic pressure ring assembly 33 includes a control ring 331, a wave spring 332 and a retaining ring 333. The wave spring 332 is wavy and is connected to the control ring 331 through the trough. The wave spring 332 is connected to the retaining ring 333 through the crest. The retaining ring 333 is transitionally or interference fit between the wave spring 332 and the mounting seat 1.

[0025] The wavy wave spring 332 can distribute force more evenly through its curved shape. When the wave spring 332 contacts the control ring 331 and the retaining ring 333, force is transmitted through the peaks and troughs of the wave spring, thereby reducing local stress concentration.

[0026] In this embodiment, the elastic deformation of the wave spring 332 allows the bearing to move up and down appropriately and adapt to the slight movement of the ball 32 and other mechanical components, reducing direct contact between them, thereby achieving the purpose of reducing noise and improving rotation efficiency.

[0027] The wave spring 332 can be a sheet-shaped wave spring 332 or a round wire wave spring 332. Furthermore, the wave spring 332 can be a single-layer wave spring 332, a multi-layer laminated wave spring 332, or a multi-layer stacked top-to-top wave spring 332. To facilitate the production and installation of the wave spring 332, a single-layer sheet-shaped closed-end wave spring 332 is preferred in this embodiment.

[0028] The single-layer sheet-shaped closed-end wave spring 332 of the embodiment is formed by welding two half-ring wave springs 332 which are identical in shape and have open ends corresponding to each other. The half-ring wave spring 332 is punched into a flat ring from an annealed steel sheet, then a forming die is used to press the corrugated shape, and finally the product is hardened by quenching and tempered to polish. Through the above settings, the single-layer sheet-shaped closed-end wave spring 332 of the embodiment has strong load capacity.

[0029] The sine wave spring 332 has a sine shape, can provide larger elastic deformation and energy storage in limited space, and reduces impact and vibration.

[0030] The mounting seat 1 of the embodiment is provided with the insertion piece 4, which facilitates the user to install the pattern seat on the rotating seat 2.

[0031] The above-described embodiments are only preferred embodiments of the utility model, and cannot be used to limit the protection scope of the utility model. Any non-substantial changes and modifications made by those skilled in the art on the basis of the utility model belong to the protection scope of the utility model.
