Description

Technical Field

[0001] This application relates to the field of load-bearing wheel technology, and in particular to a load-bearing wheel with dustproof function. Background Technology

[0002] Load-bearing rollers are mechanical components widely used in logistics transportation, industrial equipment, and warehousing systems, primarily for supporting and moving heavy objects. Their core function is to reduce friction through the rolling motion of the rollers, thereby achieving efficient and labor-saving handling. Load-bearing rollers typically consist of a hub, bearings, and connecting components, and their performance and durability directly affect the working efficiency and service life of the equipment.

[0003] Existing load-bearing wheels often lack effective protective structures for their internal bearing assemblies, leaving them exposed to the external environment for extended periods. This makes them highly susceptible to contaminants such as dust and sand from penetrating the bearings. This not only impairs lubrication but also accelerates bearing wear and can even cause jamming or abnormal noises. Such problems are particularly prominent in dusty industrial settings, severely impacting the service life and operational stability of the load-bearing wheels. Summary of the Invention

[0004] The purpose of this application is to improve dustproof performance and extend the service life of the load-bearing wheels.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A connecting assembly is included, the connecting assembly having a rolling assembly inside. The rolling assembly includes a hub, with grooves on both sides of the hub. An annular groove is formed on the inner wall of each groove. A dustproof plate is installed inside the groove. An annular plate is fixedly connected to the outer wall of the dustproof plate, located inside the annular groove. A connecting column is fixedly connected to the outer wall of the annular plate. A clamping plate is fixedly connected to one end of the connecting column, and there are multiple clamping plates. The outer wall of each clamping plate, away from the connecting column, is inclined. The cross-section of the clamping plate is conical. A rotating ring is threadedly connected to the outer wall of the connecting column. A fixed shaft passes through the center of the rotating ring. A nut is fixedly connected to one end of the fixed shaft. A sealing ring is provided at the contact point between the rotating ring and the fixed shaft.

[0006] As a preferred embodiment, the connecting assembly includes a connecting seat, the bottom of which is fixedly connected to a support plate, the fixing shaft passing through two of the support plates, and the connecting seat having multiple bolt holes inside.

[0007] As another preferred embodiment, a bearing assembly is installed inside the hub. The bearing assembly includes an outer ring, an inner ring is disposed inside the outer ring, and a roller is disposed between the inner ring and the outer ring, and there are multiple rollers.

[0008] Further preferably, the outer walls of both connecting columns are provided with slots, and there are multiple slots, all of which are located in the middle of the outer walls of the connecting columns.

[0009] Further preferably, the inner wall of the hub is provided with a flow guide groove, and there are multiple flow guide grooves. Both sides of the hub are provided with heat dissipation grooves, and there are multiple heat dissipation grooves. The multiple heat dissipation grooves are respectively connected to the multiple flow guide grooves.

[0010] Further preferably, the outer wall of the rolling component is provided with a rubber ring, and the rubber ring is made of natural rubber.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] (1) When assembling the load-bearing wheel by setting up rolling components and bearing components, first pass one end of the fixed shaft through the front support plate, then put the connecting column and dustproof plate on the fixed shaft, then put the wheel hub with the bearing assembly on the fixed shaft, then put another connecting column and dustproof plate on the fixed shaft, and finally put the threaded end of the fixed shaft through the rear support plate, and finally screw the nut on the threaded end of the fixed shaft, then insert the annular plate connected to the dustproof plate into the annular groove, with the end of the annular plate facing the wheel hub fitting against the inner wall of the annular groove, but leaving a small gap, and then through The tool is inserted into the slot on the connecting post, and the rotating ring is turned to move it along the thread towards the hub. At this time, the inclined surface of the inner wall of the rotating ring will gradually squeeze multiple conical clamps, forcing the clamps to tighten towards the fixed shaft. As the rotating ring continues to screw in, the friction between the clamps and the fixed shaft increases continuously, eventually fixing the dustproof plate and the connecting post to the fixed shaft. At the same time, a connecting component is provided at the contact point between the fixed shaft and the rotating ring to prevent dust from entering the bearing assembly from the contact point between the fixed shaft and the rotating ring, thus preventing dust from entering the bearing assembly and causing jamming and wear, and improving service life.

[0013] (2) By setting up guide grooves and heat dissipation grooves, the airflow channel formed by the guide grooves and heat dissipation grooves forces heat dissipation when the hub rotates, effectively controlling the working temperature of the bearing assembly; the symmetrically distributed heat dissipation grooves optimize the airflow path and improve the heat dissipation uniformity; the rubber ring made of natural rubber provides excellent cushioning and wear resistance.

[0026] like Figure 1-7 The diagram shows a dustproof load-bearing wheel, including a connecting assembly 1. The connecting assembly 1 includes a connecting seat 101, with a support plate 102 fixedly connected to the bottom of the connecting seat 101. A fixed shaft 209 passes through both support plates 102. Bolt holes 103 are provided inside the connecting seat 101, and there are multiple bolt holes 103. A rolling assembly 2 is provided inside the connecting assembly 1. The rolling assembly 2 includes a hub 201. Grooves 202 are provided on both sides of the hub 201. An annular groove 203 is provided on the inner wall of the groove 202. A dustproof plate 204 is installed inside the groove 202. An annular plate 205 is fixedly connected to the outer wall of the dustproof plate 204. The annular plate 205 is located inside the annular groove 203. A connecting post 206 is fixedly connected to the outer wall of the annular plate 205. A clamping plate 207 is fixedly connected to one end of the connecting post 206. There are multiple clamping plates 207, and the outer wall of the multiple clamping plates 207 is inclined at the end away from the connecting column 206. The cross-section of the clamping plate 207 is conical. The outer wall of the connecting column 206 is threaded with a rotating ring 208. A fixed shaft 209 passes through the middle of the rotating ring 208. A nut 210 is fixedly connected to one end of the fixed shaft 209. A sealing ring 211 is provided at the contact point between the rotating ring 208 and the fixed shaft 209. A bearing assembly 3 is installed inside the hub 201. The bearing assembly 3 includes an outer ring 301. An inner ring 302 is provided inside the outer ring 301. A roller 303 is provided between the inner ring 302 and the outer ring 301. There are multiple rollers 303. The outer walls of the two connecting columns 206 are provided with slots 4. There are multiple slots 4. The multiple slots 4 are all located in the middle of the outer wall of the connecting column 206.

[0027] When assembling the load-bearing wheel, first pass one end of the fixed shaft 209 through the front support plate 102, then put the connecting post 206 and the dustproof plate 204 onto the fixed shaft 209. Next, put the wheel hub 201, which has the bearing assembly 3 installed, onto the fixed shaft 209. Then, put another connecting post 206 and the dustproof plate 204 onto the fixed shaft 209. Finally, the threaded end of the fixed shaft 209 passes through the rear support plate 102. Finally, screw the nut 210 onto the threaded end of the fixed shaft 209. Then, insert the annular plate 205 connected to the dustproof plate 204 into the annular groove 203. The end of the annular plate 205 facing the wheel hub 201 fits against the inner wall of the annular groove 203, but leaves a small gap. Then, use a hex wrench to secure the connecting post 201 into the wheel hub 209. The groove 4 on the connecting post 206 is used to rotate the rotating ring 208 so that it moves along the thread towards the hub 201. At this time, the inclined surface of the inner wall of the rotating ring 208 will gradually squeeze multiple conical clamps 207, forcing the clamps 207 to tighten towards the fixed shaft 209. As the rotating ring 208 continues to rotate in, the friction between the clamps 207 and the fixed shaft 209 will continue to increase, and finally the dustproof plate 204 and the connecting post 206 will be fixed on the fixed shaft 209. At the same time, a connecting component 1 is provided at the contact point between the fixed shaft 209 and the rotating ring 208, which can prevent dust from entering the bearing assembly 3 from the contact point between the fixed shaft 209 and the rotating ring 208, thus preventing dust from entering the bearing assembly 3 and causing jamming and wear, and improving service life.

[0028] The inner wall of the hub 201 is provided with a guide groove 5, and there are multiple guide grooves 5. Both sides of the hub 201 are provided with heat dissipation grooves 6, and there are multiple heat dissipation grooves 6. The multiple heat dissipation grooves 6 are connected to the multiple guide grooves 5. The outer wall of the rolling component 2 is provided with a rubber ring 7. The rubber ring 7 is made of natural rubber. The airflow channel formed by the guide grooves 5 and the heat dissipation grooves 6 forces heat dissipation when the hub 201 rotates, effectively controlling the working temperature of the bearing component 3. The symmetrically distributed heat dissipation grooves 6 optimize the airflow path and improve the uniformity of heat dissipation. The rubber ring 7 made of natural rubber provides excellent cushioning and wear resistance.

[0029] Working principle: When assembling the load-bearing wheel, first pass one end of the fixed shaft 209 through the front support plate 102, then put the connecting column 206 and the dustproof plate 204 onto the fixed shaft 209. Next, put the wheel hub 201, which has the bearing assembly 3 installed, onto the fixed shaft 209. Then, put another connecting column 206 and the dustproof plate 204 onto the fixed shaft 209. Finally, the threaded end of the fixed shaft 209 passes through the rear support plate 102. Finally, screw the nut 210 onto the threaded end of the fixed shaft 209. Then, insert the annular plate 205 connected to the dustproof plate 204 into the annular groove 203. The end of the annular plate 205 facing the wheel hub 201 fits against the inner wall of the annular groove 203, but leaves a small gap. Then, use a tool to secure the wheel. Insert the ring into the slot 4 on the connecting post 206 and rotate the rotating ring 208 to move it along the thread towards the hub 201. At this time, the inclined surface of the inner wall of the rotating ring 208 will gradually squeeze the multiple conical clamps 207, forcing the clamps 207 to tighten towards the fixed shaft 209. As the rotating ring 208 continues to rotate in, the friction between the clamps 207 and the fixed shaft 209 will continue to increase, eventually fixing the dustproof plate 204 and the connecting post 206 onto the fixed shaft 209. At the same time, a connecting component 1 is provided at the contact point between the fixed shaft 209 and the rotating ring 208, which can prevent dust from entering the bearing assembly 3 from the contact point between the fixed shaft 209 and the rotating ring 208, thus preventing dust from entering the bearing assembly 3 and causing jamming and wear, and improving service life.
