Description

Technical Field

[0001] The utility model relates to a coiling system of a strip steel continuous annealing unit, and more specifically to a sliding bearing seat for a steel coil trolley roller. Background Art

[0002] At present, the coiler used in the pickling and annealing processes of the cold-rolled strip production line requires the steel coil trolley roller to cooperate with the coiling, such as Figure 1 In this process, the steel coil trolley rollers need to bear a large load to ensure the smooth coiling process.

[0003] like Figure 2 As shown, the steel coil trolley rollers not only have to lift the heavy steel coils, but also have to rotate in the process of unwinding. Therefore, the rollers generally use a sliding bearing seat 1 with a large load, but since the bearing 2 and the sliding bearing seat 1 and the roller journal 3 are in surface contact, the contact surface is easy to squeeze out grease during operation, and the contact surface is easy to get stuck due to lack of grease.

[0004] Because the sliding bearing must be well lubricated to effectively avoid wear, the general oil lubrication has good permeability, but it is easy to lose. Therefore, the steel coil trolley roller can only be lubricated with grease with good adhesion, but the grease will still be squeezed out of the friction surface during use. At the same time, due to poor permeability, it is difficult for the grease outside the friction surface to enter the friction surface again. Therefore, even if the amount of grease in the sliding bearing seat 1 is sufficient, the roller is still prone to jamming. Utility Model Content

[0005] In view of the defects existing in the prior art, the purpose of the utility model is to provide a sliding bearing seat for the roller of a steel coil trolley, which improves the lubrication effect of the sliding bearing seat through thin oil self-lubrication and utilizes the permeability of thin oil.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A sliding bearing seat for a steel coil trolley roller, comprising an upper bearing seat, a lower bearing seat and a bearing bush;

[0008] The upper bearing seat is connected to the upper part of the lower bearing seat to form a cavity for installing the roller journal and the bearing bush;

[0009] The lower bearing seat is provided with a thin oil groove inside, and the thin oil groove stores thin oil;

[0010] The bearing bush is sleeved on the roller journal, and part of the bearing bush is immersed in the thin oil in the thin oil tank;

[0011] An oil passage is provided on the bearing bush.

[0012] Preferably, the bearing shell is configured as a circular ring, and its inner ring is sleeved on the roller journal.

[0013] Preferably, the oil passage on the bearing bush is provided with multiple passages;

[0014] One end of each oil passage is connected to the outer surface of the bearing bush, and the other end is connected to the inner ring surface of the bearing bush.

[0015] Preferably, the thin oil tank is located below the thin oil tank.

[0016] The utility model provides a sliding bearing seat for a steel coil trolley roller, which has a wide range of applications and is mainly applied to strip coil trolley rollers, and can also be applied to other bearing parts with large loads and low speeds. The friction surface of the sliding bearing shaft can be more fully lubricated, and the reliability and service life of the bearing are greatly increased. At the same time, the friction force of the sliding bearing can be greatly reduced, making it easier to maintain a good operating state. Reduce scratches on the outer surface of the strip coil.

[0022] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Combination Figures 3 to 5 As shown, the utility model provides a sliding bearing seat for the steel coil trolley roller, which adopts an upper and lower split structure, including an upper bearing seat 10, a lower bearing seat 11 and a bearing shell 12.

[0024] The upper bearing seat 10 is connected to the upper part of the lower bearing seat 11 to form a cavity for mounting the roller journal 13 and the bearing bush 12 of the roller 16.

[0025] The lower bearing seat 11 adopts an integral structure, and an oil groove 14 is additionally provided inside the lower bearing seat 11 , and the oil groove 14 is used to store oil 15 .

[0026] The bearing bush 12 is movably mounted on the roller journal 13 , and the bearing bush 12 can rotate around the roller journal 13 .

[0027] The lower part of the bearing bush 12 is immersed in the thin oil 15 in the thin oil groove 14, ensuring good lubrication between the outside of the bearing bush 12 and the sliding bearing seat.

[0028] The bearing shell 12 is configured as a circular ring as a whole, and its inner ring is sleeved on the roller journal 13 .

[0029] The bearing bush 12 is also provided with a plurality of oil passages 17 .

[0030] One end of each oil passage 17 passes through the outer surface of the bearing shell 12, and the other end passes through the inner ring surface of the bearing shell 12. When the bearing shell 12 rotates, the thin oil 15 in the thin oil groove 14 can be brought into the roller journal 13 through the oil passage 17 inside the bearing shell 12, thereby ensuring sufficient lubrication between the roller journal 13 and the bearing shell 12.

[0031] In normal operation, the bearing 12 generally remains stationary, and only the roller journal 13 rotates. Once oil loss and jamming occur between the roller journal 13 and the bearing 12, the roller journal 13 will drive the bearing 12 to rotate together. During the rotation of the bearing 12, the oil passage 17 inside it will bring the thin oil 15 in the thin oil groove 14 into the roller journal 13. After the roller journal 13 and the bearing 12 are fully lubricated, the bearing 12 returns to stillness. During the whole process, the interior of the sliding bearing seat of the utility model is fully lubricated, and the thin oil 15 squeezed out between the roller journal 13 and the bearing 12 flows back into the thin oil groove 14, and the thin oil 15 can be repeatedly used.

[0032] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
