[0027] Example 2;

[0028] like Figure 1-6As shown, the device includes a wheel body 1, with a plurality of evenly distributed teeth 2 on the outer wall of the wheel body 1. Both ends of the wheel body 1 are provided with baffles 3, which are connected to the wheel body 1 via a connecting assembly. The inner wall of the wheel body 1 has a keyway 4 and a plurality of evenly distributed lubrication grooves 5. The connecting assembly includes symmetrically arranged sliding grooves 6 at both ends of the wheel body 1. A horizontally arranged limiting slide rod 7 is provided in each sliding groove 6. An L-shaped limiting slide bracket 8 is fitted onto the outer wall of the limiting slide rod 7. A return spring 9 is fitted onto one side of the L-shaped limiting slide bracket 8 and located on the outer wall of the limiting slide rod 7. One side of the L-shaped limiting slide bracket 8 extends outside the sliding groove 6. A limiting groove 18 matching the L-shaped limiting slide bracket 8 is provided on one side of the baffle 3. The L-shaped limiting slide 8 has a sliding hole that matches the limiting slide rod 7. The L-shaped limiting slide 8 is connected to the wheel body 1 through the return spring 9. A pull ring 10 is provided outside the slide groove 6 and on one side of the L-shaped limiting slide 8. The wheel body 1 has symmetrically arranged positioning blocks 11 at both ends. The inner wall of the baffle 3 has a positioning groove 12 that matches the positioning block 11. When installing the baffle 3, first align the positioning groove 12 on the baffle 3 with the positioning block 11 on the wheel body 1, and then attach the baffle 3 to the L-shaped limiting slide 8. Next, pull the two sets of pull rings 10. The pull rings 10 move the L-shaped limiting slide 8 closer to the center of the wheel body 1. At this time, the return spring 9 is compressed. When the L-shaped limiting slide 8 moves to the center through hole of the baffle 3, press the baffle 3 to make it fit against the wheel body 1. Then release the pull rings 10, and the return spring 9 returns to its original position, causing the L-shaped limiting slide 8 to move. The L-shaped limiting slide 8 moves into the limiting groove 18 on the baffle 3 and is limited there. By setting a connecting component, the baffle and the wheel body can be easily disassembled and assembled, facilitating future baffle replacement. The connecting component uses the limiting slide rod, L-shaped limiting slide, return spring, positioning block, and positioning groove to limit and fix the baffle.

[0029] Example 3;

[0030] like Figure 1-6As shown, the device includes a wheel body 1. The outer wall of the wheel body 1 has several evenly distributed teeth 2. Both ends of the wheel body 1 are provided with baffles 3, which are connected to the wheel body 1 via connecting components. The inner wall of the wheel body 1 has a keyway 4 and several evenly distributed lubrication grooves 5. One end of the wheel body 1 has an inclined oiling pipe 13. The wheel body 1 has inclined conveying grooves 14 that are respectively connected to a set of lubrication grooves 5 and the oiling pipe 13. The inner wall of the wheel body 1 has a guide groove 15 that is connected to the lubrication grooves 5. The oiling pipe 13 has a matching sealing block 16, which is threadedly connected to the oiling pipe 13. A rotating block 17 is provided on the side of the sealing block 16 away from the oiling pipe 13. When it is necessary to add lubricating oil to the inside of the wheel body 1, rotate the rotating block 17 to drive the sealing block 16 to rotate and remove it from the oil filling pipe 13. Then, pour the lubricating oil into the oil filling pipe 13. The lubricating oil entering the oil filling pipe 13 will be transported to a set of lubrication tanks 5 through the conveying groove 14. The lubricating oil entering the lubrication tanks 5 will flow to the other lubrication tanks 5 through the guide groove 15. By setting up the oil filling pipe, lubrication tanks, guide grooves and conveying grooves, it is convenient to add lubricating oil to the inside of the wheel body 1.

[0031] In practical applications, when installing the baffle 3, first align the positioning groove 12 on the baffle 3 with the positioning block 11 on the wheel body 1, and then attach the baffle 3 to the L-shaped limiting slide 8. Next, pull the two sets of pull rings 10. The pull rings 10 move the L-shaped limiting slide 8 closer to the center of the wheel body 1. At this time, the return spring 9 is compressed. When the L-shaped limiting slide 8 moves to the center through hole of the baffle 3, press the baffle 3 to make it fit against the wheel body 1. Then release the pull rings 10, and the return spring 9 returns to its original position, causing the L-shaped limiting slide 8 to move. The L-shaped limiting slide 8 moves into the limiting groove 18 on the baffle 3 and is then limited. The connecting assembly facilitates the assembly and disassembly of the baffle and the wheel body. For easy replacement of the baffle, the connecting assembly uses a limiting slide rod, an L-shaped limiting slide, a return spring, a positioning block, and a positioning groove to limit and fix the baffle. The operation is simple, requiring no external tools for disassembly and assembly, resulting in high installation efficiency. When it is necessary to add lubricating oil to the inside of the wheel body 1, rotating the rotating block 17 causes the sealing block 16 to rotate and be removed from the oil filling pipe 13. Then, the lubricating oil is poured into the oil filling pipe 13. The lubricating oil entering the oil filling pipe 13 will be transported to a set of lubrication grooves 5 through the conveying groove 14. The lubricating oil entering the lubrication grooves 5 will flow to the other lubrication grooves 5 through the guide groove 15. By setting up the oil filling pipe, lubrication grooves, guide grooves, and conveying grooves, it is convenient to add lubricating oil to the inside of the wheel body 1.
