[0001] This utility model relates to the field of bearing technology, and in particular to a multi-stage bearing automatic speed regulation device for electric tricycles. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. The bearings inside electric tricycles automatically adjust their speed.

Therefore, this invention proposes a multi-stage bearing automatic speed control device for electric tricycles. Utility Model Content

[0030] Example

[0031] like Figures 1 to 3As shown, this utility model proposes a multi-stage bearing automatic speed regulating device for an electric tricycle, including a housing 1. A split box 2 is fixedly connected to one side of the housing 1. A bearing rod 3 is rotatably connected inside the housing 1. A cover plate 4 is provided on one side of the housing 1. The bearing rod 3 can drive the bearing to rotate inside the housing 1. The housing 1 is filled with lubricating oil, which lubricates the bearing during rotation. A rotating plate 7 is provided outside the bearing rod 3. When the bearing rod 3 rotates, it can drive the rotating plate 7 to carry the lubricating oil. A collection groove 5 is fixedly connected to the inner side of the housing 1 near the top. The lubricating oil will enter the collection groove 5 through the rotation plate 7. A lubrication port 6 is provided at the bottom of the collection groove 5, which allows the lubricating oil inside the collection groove 5 to flow out, thereby lubricating the split box 2 and the bearing. The bearing rod 3 passes through one side of the housing 1. There are multiple sets of rotating plates 7 arranged in a circumferential array. Multiple sets of rotating plates 7 drive the flow of lubricating oil better. There are multiple sets of lubrication ports 6 arranged in a linear array. The multiple structure of lubrication ports 6 improves the flow of lubricating oil.

[0032] For further details, please refer to Figure 3 and Figure 4 A rotating sleeve 8 is provided outside the bearing rod 3. The rotating sleeve 8 is rotatably connected inside the housing 1. The bearing rod 3 can drive the rotating sleeve 8 to rotate inside the housing 1. One end of the rotating plate 7 is fixedly connected to the outside of the rotating sleeve 8. The rotating sleeve 8 can drive the rotating plate 7 to deliver lubricating oil. A positioning component is provided inside the rotating sleeve 8. The positioning component includes an embedding groove 9. There are multiple sets of embedding grooves 9 arranged in a circumferential array inside the rotating sleeve 8. The bearing rod 3 can be embedded in the embedding groove 9 to drive the rotating sleeve 8 to rotate. An embedding block 10 is slidably connected inside the embedding groove 9. The embedding block 10 is fixedly connected to the outside of the bearing rod 3. The bearing rod 3 drives the rotating sleeve 8 to rotate inside the embedding groove 9 through the embedding block 10. A rotating shaft 11 is rotatably connected inside the collection tank 5. The rotating shaft 11 can rotate inside the collection tank 5. A pushing component is provided outside the rotating shaft 11.

[0033] For further details, please refer to Figure 3 , Figure 5 and Figure 6The driving component includes a spiral plate 12, which is fixedly connected to the outside of the rotating shaft 11 in a spiral shape. The rotation of the rotating shaft 11 can drive the spiral plate 12 to push the lubricating oil inside the collection tank 5. A transmission belt 14 is rotatably connected to the outside of the rotating shaft 11. The inner side of the transmission belt 14 is rotatably connected to the outside of the bearing rod 3 away from the rotating shaft 11. When the bearing rod 3 rotates, it can drive the transmission belt 14 to transmit kinetic energy to the rotating shaft 11, thereby making the rotating shaft 11 rotate. A transmission port 13 is opened on the inner side of the collection tank 5 near the bottom. The transmission belt 14 is set inside the transmission port 13. It is more convenient for the transmission belt 14 to rotate inside the transmission port 13. The edge of the transmission port 13 is rounded to avoid wear with the transmission belt 14. The outer diameter of the bearing rod 3 is larger than the outer diameter of the rotating shaft 11, and the rotation speed of the rotating shaft 11 is faster than that of the bearing rod 3.

[0034] In this embodiment, when in use, the cover plate 4 is removed from one side of the housing 1. At this time, the bearing can be installed on the outside of the bearing rod 3 and inside the split box 2. Then, lubricating oil is added to the housing 1 and the split box 2. After the lubricating oil is added, the cover plate 4 can be installed on one side of the housing 1 to seal the housing 1.

[0035] At this point, the bearing rod 3 can be rotated. When the bearing rod 3 rotates, it will drive the insert block 10 to drive the rotating sleeve 8 to rotate inside the insert groove 9. In this way, the rotating sleeve 8 will drive the rotating plate 7 to transport the lubricating oil inside the housing 1. When the rotating plate 7 reaches the position of the collecting groove 5, the lubricating oil will enter the collecting groove 5 due to the centrifugal force. In this way, the lubricating oil will be transported out along the lubrication port 6 inside the collecting groove 5. In this way, the lubricating oil can drip onto the bearing rod 3 and the bearing outside the bearing rod 3 for lubrication.

[0036] When the bearing rod 3 rotates, it drives the transmission belt 14 to transmit power. The transmission belt 14 then drives the rotating shaft 11 to rotate inside the collection tank 5. The rotating shaft 11 then drives the spiral plate 12 to rotate inside the collection tank 5, thereby pushing the lubricating oil that has entered the collection tank 5. This allows the lubricating oil to be more easily pushed out along the lubrication port 6 inside the collection tank 5, thus lubricating the bearing rod 3 and the bearing outside the bearing rod 3.

[0037] When the transmission belt 14 is driven outside the bearing rod 3, it will be transmitted inside the transmission port 13. Since the outer diameter of the bearing rod 3 is larger than that of the rotating shaft 11, the rotation speed of the rotating shaft 11 will be faster than that of the bearing rod 3. Furthermore, the rounded corners of the transmission port 13 can prevent the transmission belt 14 from rubbing against the transmission port 13, which would cause the transmission belt 14 to wear.

[0038] It should be noted that this device uses a bearing rod 3 to drive a rotating shaft 11 to rotate via a transmission belt 14. This rotating shaft 11 then drives a spiral plate 12 to rotate inside the collection tank 5. The rotation of the bearing rod 3, in turn, drives a rotating plate 7 to deliver lubricating oil into the collection tank 5. In this way, the spiral plate 12 can push the lubricating oil inside the collection tank 5 out along the lubrication port 6, allowing the lubricating oil to drip onto the bearing rod 3 and the outside of the bearing. This reduces the wear of the bearing rod 3 and the bearing, and increases their service life.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
