[0002] When in use, the bearing guide wheel can conduct direction guidance. The guide wheel can guide an object to move in a predetermined direction, ensuring the stability and accuracy of the movement. In mechanical devices such as conveyor belts and wheeled mobile robots, the guide wheel plays a crucial role in reducing friction. Through the rolling of the wheel, the guide wheel can reduce the sliding friction between the object and the ground or other contact surfaces, thereby reducing energy consumption and wear and improving stability. In high-speed operation or complex environments, the guide wheel can increase the stability of the device and prevent deviation or overturning caused by external force interference.

[0003] At present, the guide wheel is a device for guiding or controlling the movement of an object, usually composed of a wheel and a shaft. The role of the guide wheel is to make the movement direction of the object more stable, avoiding deviation from the predetermined track or path during the movement. At the same time, it is also a connecting part, which has the effect of connecting the shaft and the belt while maintaining a small friction state.

[0004] However, the current bearing guide wheels often consist of three parts: a bearing, a guide wheel, and an inner ring. The fitting method of the three parts is interference fit, resulting in deformation of the middle bearing under bidirectional force, abnormal internal structure of the bearing body, affecting the smoothness of rotation and the service life of the bearing.

[0033] Please refer to Figures 1-7 As shown, a bearing guide wheel includes: a guide wheel body 1, a bearing body 5, a stainless steel inner ring 2, a snap ring 3, and a sealing and limiting assembly 4. The guide wheel body 1 is made of an aluminum shell. The outer ring of the bearing body 5 is installed on the inner wall of the guide wheel body 1 through a transition fit. A convex ring is provided on the inner wall of the guide wheel body 1, and one side of the outer ring of the bearing body 5 is clamped and limited with the convex ring. The stainless steel inner ring 2 is installed on the inner side of the inner ring of the bearing body 5 through an interference fit. An installation groove is formed on the inner wall of the guide wheel body 1. The snap ring 3 is arranged in the installation groove and is installed inside the guide wheel body 1 through a clearance fit. One side wall of the snap ring 3 is clamped and limited with one side wall of the outer ring of the bearing body 5. The sealing and limiting assembly 4 is arranged on one outer wall of the guide wheel body 1.

[0034] Specifically, by providing the snap ring 3 and the convex ring on the guide wheel body 1, the two sides of the outer ring of the bearing body 5 can be limited, making it not easy for the bearing body 5 to fall off. The overall matching method of the parts becomes more reasonable, increasing the service life of the bearing guide wheel. At the same time, the guide wheel body 1 has a self-limiting feature that can limit the snap ring 3, making the installation of the snap ring 3 more stable. Furthermore, the limiting effect of the snap ring 3 and the convex ring on the bearing body 5 is better, avoiding deformation caused by the bearing being stressed in both directions in the middle, greatly improving the smoothness of the rotation of the bearing body 5. During use, the bearing body 5 is installed inside the guide wheel body 1 through a transition fit.

[0035] In this embodiment, the sealing and limiting assembly 4 includes a sealing cover 41, mounting bolts 42, a rotating block 43, a threaded rod 44, a limiting block 45, and a washer 46. The sealing cover 41 is fixed on one outer wall of the guide wheel body 1 through the mounting bolts 42. One end of the threaded rod 44 is fixedly connected to the rotating block 43. The threaded rod 44 is movably inserted into the interior of the sealing cover 41. The other end of the threaded rod 44 is connected to the limiting block 45 through a bearing. The washer 46 is fixedly installed on one outer wall of the limiting block 45. The limiting block 45 is movably inserted into the interior of the stainless steel inner ring 2.

[0036] Specifically, during use, the sealing cover 41 is installed on one side of the guide wheel body 1 and fixed using mounting bolts 42. The rotating block 43 can be rotated as needed, so that the limiting block 45 moves to a suitable position, thereby limiting the axial installation position of the guide shaft and preventing excessive insertion. This is beneficial for controlling the installation position of the guide shaft, making its installation faster and more accurate. At the same time, the sealing cover 41 can protect one end of the guide shaft, preventing it from being damaged due to collision with the outside world. At the same time, it seals the installation of the guide shaft and the inner ring and the bearing body 5 to prevent foreign objects from flying in.

[0037] The inner side wall of the stainless steel inner ring 2 is provided with a limiting card slot, and the side wall of the stainless steel inner ring 2 is provided with a through hole.

[0038] Specifically, the limiting card slot is beneficial for the insertion of the shaft key and plays a key role in the relative radial fixation. At the same time, bolts are inserted into the through holes to fix the inner ring and the guide shaft, preventing relative displacement between the two and avoiding loosening of the guide shaft.

[0039] The snap ring 3 is arranged in an arc shape, and mounting holes are opened inside both ends of the snap ring 3.

[0040] Specifically, during use, the claw can be inserted into the mounting hole, and the snap ring 3 can be bent inward, and then the snap ring 3 is installed inside the mounting groove. After releasing the claw, the snap ring 3 is embedded in the mounting groove. At the same time, the inner ring stainless steel fitting cooperates with the guide shaft to achieve rotational movement, and the movement is transmitted to the aluminum shell to achieve the rotational movement of the aluminum shell. The belt is assembled in the groove of the aluminum shell to achieve guiding movement.

[0041] In summary, compared with the prior art, the bearing guide wheel has at least the following beneficial effects: by providing the snap ring 3 and the guide wheel body 1 with a convex ring, the two sides of the outer ring of the bearing body 5 can be limited, making it not easy for the bearing body 5 to fall off. The overall matching method of the parts becomes more reasonable, increasing the service life of the bearing guide wheel. At the same time, the guide wheel body 1 has a self-limiting feature to limit the snap ring 3, making the installation of the snap ring 3 more stable, and thus making the limiting effect of the snap ring 3 and the convex ring on the bearing body 5 better, avoiding deformation caused by the two-way force on the middle bearing, and greatly improving the smoothness of the rotation of the bearing body 5. During use, the bearing body 5 is installed inside the guide wheel body 1 through an interference fit.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention.
