[0041] The implementation of the present application will be described by specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification.

[0042] It should be understood that the structures, proportions, sizes, etc. shown in the drawings attached to the specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the implementation conditions of the present application, so they do not have technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the specification are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship without substantial changes in technical content is also considered as the scope of the present application.

[0043] As shown in Figures 1 to 4 The present application provides a side-fixed runner mounting structure.

[0044] The side-fixed runner mounting structure is used to mount a runner, comprising:

[0045] A runner frame 1, the runner frame 1 comprises a containing cavity 11 containing a runner 2, the first bearing seat 13 is fixed on the runner frame 1, the first bearing 131 is arranged in the first bearing seat 13, and the runner 2 is arranged in the containing cavity 11;

[0046] The first rotating shaft 14 is inserted into the first bearing 131 at one end and is provided with a first rotating shaft mounting seat 15 at the other end. The first rotating shaft mounting seat 15 is detachably connected to one side of the rotating wheel 2, and the rotating shaft of the rotating wheel 2 is in the same straight line with the first rotating shaft 15.

[0047] In an embodiment, one end of the first rotating shaft 14 is connected to the first bearing 141 in an interference fit. Specifically, the diameter of the first rotating shaft 14 is slightly larger than the diameter of the inner ring of the first bearing 141. The interference fit can effectively prevent the first rotating shaft 14 from loosening or sliding during rotation, ensuring the stability of the rotating wheel.

[0048] In a specific embodiment, when connecting the first rotating shaft 14 and the first bearing 131, a lubricant is applied to the surfaces of the first rotating shaft 14 and the first bearing 131 to reduce installation resistance. At the same time, the pressure equipment is used to gradually insert one end of the first rotating shaft 14 into the first bearing 131, and ensure the centration of the first rotating shaft 14 and the first bearing 131. After installation is completed, the tightness of the interference fit between one end of the first rotating shaft 14 and the first bearing 131 is detected to ensure that the assembly effect meets the design requirements.

[0049] In a specific embodiment, the first bearing 131 is a cylindrical roller bearing, which provides smooth and low-friction rotation support for the rotating wheel. The cylindrical roller bearing and the first bearing seat 13 are in a transition fit, which can ensure stability during installation and facilitate maintenance and disassembly later. The transition fit refers to the fit between the inner ring or outer ring of the cylindrical roller bearing and the first bearing seat 13, which is neither too tight nor too loose, but a fit between the two. The hydraulic press or manual pressing tool is used to uniformly press the bearing into the first bearing seat 13, avoiding damage to the bearing or poor assembly caused by uneven force. After installation is completed, the bearing is checked to ensure that it can rotate freely and does not jam.

[0050] In an embodiment, as shown in Figure 4 , the rotating wheel frame 2 is also fixed with a second bearing seat 16, and the second bearing seat 16 is provided with a second bearing.

[0051] In an embodiment, as shown in Figure 4 , the side-fixed rotating wheel mounting structure further comprises a second rotating shaft 17, one end of the second rotating shaft 17 is inserted into the second bearing, and the other end is provided with a second rotating shaft mounting seat 18. The second rotating shaft mounting seat 18 is detachably connected to the other side of the rotating wheel 2, and the rotating shaft of the rotating wheel 2 is in the same straight line with the second rotating shaft 18.

[0052] It should be noted that the structure of the two rotating shafts provides more support points for the rotating wheel, so that the rotating wheel can rotate more stably, and the performance decline caused by vibration or instability factors is reduced. The two rotating shafts can provide more redundancy and backup, so that when one of the rotating shafts fails, the other rotating shaft can still continue to work, thereby ensuring the continuous operation of the rotating wheel. Moreover, the three rotating shaft, the first rotating shaft and the second rotating shaft are located on the same straight line to ensure that the rotating wheel does not vibrate when rotating, thereby delaying the wear of the rotating wheel and the rotating shaft.

[0053] In an embodiment, one end of the second rotating shaft is connected with the second bearing in an interference fit. Specifically, the diameter of the second rotating shaft is slightly larger than the diameter of the inner ring of the second bearing. The interference fit connection can effectively prevent the second rotating shaft from loosening or sliding during rotation, thereby ensuring the stability of the rotating wheel.

[0054] In a specific embodiment, when connecting the second rotating shaft with the second bearing, a lubricant is applied to the surface of the second rotating shaft and the second bearing to reduce the installation resistance. At the same time, the pressure equipment is used to gradually insert one end of the second rotating shaft into the second bearing, and ensure the centration of the second rotating shaft and the second bearing. After installation is completed, the tightness of the interference fit connection between the second end of the second rotating shaft and the second bearing is detected to ensure that the assembly effect meets the design requirements.

[0055] In a specific embodiment, the second bearing is a cylindrical roller bearing, which provides stable and low-friction rotating support for the rotating wheel. The cylindrical roller bearing and the second bearing seat are in a transition fit, so as to ensure stability during installation and facilitate later maintenance and disassembly. The transition fit refers to the fit between the inner ring or the outer ring of the cylindrical roller bearing and the second bearing seat, which is neither too tight nor too loose, but a fit between the two. The hydraulic press or the manual pressing tool is used to uniformly press the bearing into the second bearing seat, so as to avoid damage to the bearing or poor assembly caused by uneven force. After installation is completed, the bearing is checked to ensure that the bearing can rotate freely and does not appear to be stuck.

Similarly, one of the two intersecting second beams is vertically positioned and connected to the wheel frame 1 at both ends, while the other second beam is horizontally positioned and connected to the wheel frame 1 at both ends. The vertically positioned first beam and the vertically positioned second beam are symmetrical, as are the horizontally positioned first beam and the horizontally positioned second beam.
