Description

Technical Field

[0001] The utility model relates to the technical field of silent wheels, in particular to a double-bearing anti-stuck silent wheel. Background Art

[0002] Silent wheels are special tires used to reduce noise when vehicles or equipment are running. They usually use special rubber materials and structures. In order to solve the problems of jamming and noise encountered during use, a double-bearing anti-jam system is designed. The system uses two bearings to support the wheels to increase the stability and balance of the wheels.

[0003] Although the existing silent wheel uses two bearings, it still lacks synchronization because the rotation speed and direction of the two bearings are different, which will cause uneven load and stress on the silent wheel and cause the silent wheel to get stuck.

[0004] Therefore, we provide a double-bearing anti-seizure silent wheel. Utility Model Content

[0005] The purpose of the utility model is to provide a double-bearing anti-stuck silent wheel to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-bearing anti-seizing silent wheel, comprising a rotating shaft body and a rotating mechanism, the left and right ends of the rotating shaft body are both provided with main fixing holes, a spring shaft is installed on the outside of the rotating shaft body, a support is installed at one end of the rotating shaft body, and a rotating mechanism is installed on the outside of the spring shaft;

[0007] The rotating mechanism includes bearings, a transmission chuck, a tire and a protective plate. Bearings are installed on the outside of the spring shaft, a transmission chuck is installed on one side of the bearing, and a wheel is installed on the outside of the transmission chuck. Preferably, a transmission hole is opened on one side of the bearing, and the transmission holes are opened in eight groups.

[0008] Preferably, transmission shafts are fixedly mounted on both left and right sides of the transmission chuck, and eight groups of transmission shafts are installed.

[0009] Preferably, the spring shaft is rotatably connected to the tire via a bearing, and the tire is made of nylon.

[0010] Preferably, holes are opened on the surface of the protective plate, and the material of the protective plate is plastic.

[0011] Preferably, the spring shaft comprises a support ring, a spring and a shell, a support ring is installed on the outer side of the rotating shaft body, a spring is welded to the outer side of the support ring, the other end of the spring is welded to the shell, and the shell and the bearing are welded.

[0012] Preferably, auxiliary fixing holes are provided on both sides of the bottom end of the support, bolts are installed inside the auxiliary fixing holes, and the bolts penetrate the auxiliary fixing holes and the hole and extend to the inside of the main fixing hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The double-bearing anti-stuck silent wheel is installed on the outside of the equipment through the setting of the rotating mechanism. When the equipment is moved, the silent wheel rotates, and the nylon tire can reduce friction, transmit power, guide and position, and absorb sound and reduce shock. While the bearing is rotating, the spring can make the rotating shaft body adaptively adjust and reduce uneven load and stress, providing better jamming protection. The transmission chuck drives the bearing to move synchronously. The transmission chuck can make the bearing achieve synchronous movement, so that the system has higher stability and precision. When the silent wheel rotates, the plastic protective plate is lightweight, wear-resistant and not easy to deform, which can prevent debris from entering the inside of the bearing to avoid causing the pulley to get stuck.

[0015] 2. Through the setting of the support, the rotating shaft body can support the tire, the bolts can connect and fix the rotating shaft and the support, and can ensure the normal transmission force and rotational force between the two. The support provides a stable platform so that the pulley can rotate freely. BRIEF DESCRIPTION OF THE DRAWINGS

When the silent wheel rotates, the nylon tire 43 can reduce friction, transmit power, guide and position, as well as absorb sound and reduce shock. The third step is that while the bearing 41 is rotating, the spring 22 can make the rotating shaft body 1 adaptively adjust and reduce uneven loads and stress, providing better jamming protection. The fourth step is that the transmission chuck 42 drives the bearing 41 to move synchronously. The transmission chuck 42 can make the bearing 41 achieve synchronous movement, so that the system has higher stability and precision. The fifth step is that when the silent wheel rotates, the plastic protective plate 44 is lightweight, wear-resistant and not easy to deform, which can prevent debris from entering the inside of the bearing 41 to avoid causing the pulley to get stuck. This completes the use process of a double-bearing anti-stuck silent wheel.
