[0034] Example 1

[0035] Please refer to the attached document. Figure 1 - Figure 9 This paper illustrates a bearing coating structure provided in an embodiment of this application, which includes a wheel body 1 and a rubber component fitted on the outer side of the wheel body 1. In this solution, an undercut groove structure is provided at the mating point between the wheel body 1 and the rubber component. The rubber component is an injection-molded structural component, and the outer shape of the rubber component is a standard shape (adapted to the sliding door track). The inner side of the rubber component fits with the outer side of the wheel body 1. Therefore, this solution also improves the inner structure of the rubber component. The undercut groove structure is used to improve the connection stability between the wheel body 1 and the rubber component and prevent the rubber component from falling off during use.

[0036] Specifically, the undercut groove structure includes: an annular opening 104a, and a protrusion 104b fixedly provided at the end side 104a1 of the annular opening 104a. One or two protrusions 104b can be designed, such as... Figure 3 , Figure 9 In the structure shown, there are two protrusions 104b. The inner side of the annular opening 104a and the inner side of the protrusion 104b form a restrictive area. The component filled in the restrictive area can restrict the movement of the colloid component along the axial direction of the wheel body 1, thereby ensuring the stable connection between the wheel body 1 and the colloid component and preventing the colloid component from falling off during use. In addition, an angle θ is set between the end side 104a1 and the cross section of the wheel body 1, that is, the end side 104a1 is an inclined surface. The cross sections of the restrictive area formed in this way are all of different sizes. During use, even if the colloid component and the wheel body 1 become loose, the colloid component and the wheel body 1 cannot rotate relative to each other, which further improves the connection stability between the wheel body 1 and the colloid component.

[0037] In one embodiment, the included angle θ between the end side 104a1 and the cross section of the wheel body 1 is designed to be greater than 3° and less than 5°.

[0038] In one embodiment, the wheel body 1 includes an inner ring 101, a rolling element 102, and an outer ring component arranged sequentially from the inside to the outside. The inner ring 101 and the outer ring component can rotate freely by means of the rolling element 102. An end cap 103 is fixedly installed at the end of the inner ring 101. The end cap 103 blocks the gap between the inner ring 101 and the outer ring component, which has a dustproof effect. Both ends of the inner ring 101 are provided with an extension portion 101a for installation. The design of the extension portion 101a can reduce the process of installing washers (in the traditional wheel body 1 installation process, washers need to be fitted on both ends of the central shaft to avoid wear between the ends of the wheel body 1 and the frame). Its main function is to upgrade the process and facilitate installation.

[0039] Example 2

[0040] Please refer to the attached document. Figure 1 - Figure 3 This paper illustrates a bearing-coated structure in the form of a cam structure. The bearing-coated structure in the form of a cam structure is generally installed in the track of doors and windows. Unlike the scheme of the above embodiment one, its outer ring is designed as follows: the first outer ring 10401 of the wheel body 1 constituting the cam structure, that is, the outer side of the first outer ring 10401 is a circular side, and the ring opening 104a is opened on the outer side of the first outer ring 10401. The rubber component is the first rubber body 2a constituting the cam structure, that is, the outer side of the first rubber body 2a is a convex arc structure.

[0041] In this embodiment, the cross-sectional shape of the protrusion 104b is designed to be rectangular, which facilitates processing and provides high structural strength.

[0042] Example 3

[0043] Please refer to the attached document. Figure 7 - Figure 9 This paper illustrates a bearing coating structure with a concave wheel structure. This type of bearing coating structure is typically installed in the lower track of doors and windows. Unlike the scheme in Embodiment 1 described above, the outer ring component is a second outer ring 10402 constituting the concave wheel structure. Specifically, a notch is provided on the outer side of the second outer ring 10402, and an annular opening 104a is opened inside the notch on the outer side of the second outer ring 10402. The adhesive component is a second adhesive 2b constituting the concave wheel structure. Specifically, the second adhesive 2b is located inside the notch on the outer side of the second outer ring 10402, and the outer side of the second adhesive 2b is an arc-shaped notch.

[0044] In this embodiment, the protrusion 104b has a rectangular cross-sectional shape, which can provide the second colloid 2b with space to the maximum extent and ensure that the second colloid 2b has sufficient thickness.
