Description

Technical Field

[0001] The utility model belongs to the technical field of side guide wheels, and in particular relates to a side guide wheel for a winding trolley. Background Art

[0002] In the steel industry, the coiling trolley is used to transport steel coils from the coiler to the saddle or other places. However, during the use of the existing coiling trolley wheels, the wheel edges often suffer severe wear when rolling, which not only shortens the service life of the wheels, but also may cause safety accidents. When the existing coiling trolley wheels are worn during use and the wheels are replaced, it is difficult to manually disassemble and repair them because the wheels are closely connected to other components. In addition, the wheel life cycle is short and needs to be replaced frequently, which increases the workload of maintenance personnel and reduces the efficiency of disassembly and replacement. Once the coiling trolley fails, the production line will frequently slow down or stop, thereby affecting the transportation efficiency of the coiling trolley. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1 A side guide wheel for a winding trolley shown in the figure comprises:

[0019] A side wheel axle 1, wherein a frame 2 is sleeved in the middle of the side wheel axle 1, a nut 3 is threadedly connected to the surface of the side wheel axle 1 and located at the top of the frame 2, and a cotter pin 4 is provided on the surface of the nut 3 to prevent the nut 3 from loosening, two sets of bearings 5 ​​are sleeved on the surface of the side wheel axle 1 and located at the bottom of the frame 2, a side guide wheel 6 is sleeved on the surface of the bearing 5, and an oil cup 7 for lubricating the bearing 5 is provided on the surface of the side wheel axle 1.

[0020] A double-ear stop washer 8 is sleeved on the surface of the side wheel shaft 1 and is located between the frame 2 and the nut 3. The double-ear stop washer 8 can provide additional support when the nut 3 is tightened, which can effectively reduce the friction and vibration between the nut 3 and the side wheel shaft 1, thereby extending the service life of the side wheel shaft 1 and the nut 3. A first spacer sleeve 9 is sleeved on the surface of the side wheel shaft 1 and is located between the frame 2 and the bearing 5. The first spacer sleeve 9 forms a layer of isolation protection between the surface of the side wheel shaft 1 and the frame 2 to prevent the side wheel shaft 1 from directly contacting the frame 2 and generating friction, thereby reducing the wear and damage of the side wheel shaft 1 and the frame 2 and extending the service life of the side wheel shaft 1.

[0021] The bearing 5 includes a bearing inner ring 10 and a bearing outer ring 11. The bearing inner ring 10 is sleeved on the surface of the side wheel shaft 1, and the side guide wheel 6 is sleeved on the surface of the bearing outer ring 11. A plurality of balls 12 are rollingly connected between the bearing inner ring 10 and the bearing outer ring 11.

[0022] A second spacer sleeve 13 is provided between the two groups of bearings 5 ​​, and the second spacer sleeve 13 can separate the two groups of bearings 5 ​​to avoid direct contact or friction between the two groups of bearings 5 ​​, thereby reducing the risk of wear and damage to the bearings 5 ​​.

[0023] An oil pipe 14 is provided in the side wheel shaft 1 and one end of the oil pipe 14 is connected to the oil cup 7. The other end of the oil pipe 14 extends to between the two groups of bearings 5 ​​through a short tube.

[0024] The side guide wheel 6 is made of 40Cr material and the surface is quenched. The hardness of the side guide wheel 6 is enhanced by quenching, and the thickness of the quenching layer is between 3mm and 5mm, which not only ensures the hardness and wear resistance of the side guide wheel 6, but also avoids material embrittlement caused by an excessively large quenching layer.

At the same time, the side guide wheel 6 has the advantage of simple installation and disassembly. If the side guide wheel 6 is worn, it is only necessary to remove the nut 3 that fastens the side wheel shaft 1, so that the side guide wheel 6 can be removed from the trolley, thereby realizing rapid replacement of the side guide wheel 6.

[0026] The side guide wheel 6 is made of 40Cr material and is tempered to have a hardness between 241HBW and 286HBW. The surface of the side guide wheel 6 is quenched to have a hardness between 40HRC and 45HRC, and the thickness of the quenching layer is between 3mm and 5mm. This ensures the hardness and wear resistance of the side guide wheel 6 and avoids material embrittlement caused by an excessively large quenching layer. Through such material and process treatment, the side guide wheel 6 has excellent wear resistance and high temperature resistance, can effectively reduce the wear of the wheel edge of the side guide wheel 6, improve the service life and safety of the side guide wheel 6, and thus reduce the frequency of replacement.

[0027] By injecting lubricating oil into the oil cup 7, the lubricating oil in the oil cup 7 flows into the gap 15 between the two sets of bearings 5 ​​through the oil pipe 14, and slowly penetrates into the bearing inner ring 10, the bearing outer ring 11 and the ball 12 through the gap 15, thereby lubricating the inside of the bearing 5, reducing the friction coefficient of the bearing 5, reducing the friction loss of the bearing 5 during the rotation process, and thus extending the service life of the bearing 5.
