[0019] At present, the gap is arranged between the large gland 1 and the small gland 2 of the waste material winding bearing seat, and the waste material can directly reach the bearing through the gap, and the service life of the bearing is shortened due to the excessive waste material and being stuck for a long time. Figure 2As shown, the application provides a bearing protection device, which comprises a large gland 1, a small gland 2, a bearing seat outer sleeve 3 and a bearing seat inner sleeve 4. The large gland 1 and the small gland 2 can rotate relative to each other, and a gap is formed between the large gland 1 and the small gland 2. A sealing element 5 is arranged between the large gland 1 and the small gland 2, and the sealing element 5 is a skeleton oil seal. The sealing element 5 is arranged in the gap, and can effectively prevent waste from entering the gap, thereby prolonging the service life of the bearing. The large gland 1 is connected to the bearing seat outer sleeve 3 and is fixed to the bearing seat outer sleeve 3 by a fixing bolt. The small gland 2 is connected to the bearing seat inner sleeve 4 and is fixed to the bearing seat inner sleeve 4 by a fixing bolt. First and second bearings 6 and 7 are arranged between the bearing seat outer sleeve 3 and the bearing seat inner sleeve 4. The first bearing 6 is located above the second bearing 7. The large gland 1 contacts the outer ring of the first bearing 6, and the small gland 2 contacts the inner ring of the first bearing 6.

[0020] First and second bearing spacing sleeves 8 and 9 are arranged between the first and second bearings 6 and 7. The outer wall of the first bearing spacing sleeve 8 contacts the inner wall of the bearing seat outer sleeve 3, and the inner wall of the second bearing spacing sleeve 9 contacts the outer wall of the bearing seat inner sleeve 4. The first and second bearing spacing sleeves 8 and 9 have a gap therebetween.

[0021] As shown in Figure 3 and Figure 4 The large gland 1 is integrally formed and comprises a connecting portion 11, a sealing portion 12 and a supporting portion 13. The connecting portion 11 is provided with a bolt hole through which a bolt is passed to fix the large gland 1 to the bearing seat outer sleeve 3. The sealing portion 12 is arranged on the inner side of the connecting portion 11, and the supporting portion 13 is arranged at the bottom of the connecting portion 11 and contacts the outer ring of the first bearing 6. The small gland 2 is integrally formed and comprises a boss 21 and a base 22. The boss 21 is arranged at the top of the base 22, and the bottom of the base 22 contacts the inner ring of the first bearing 6. The boss 21 has a gap between its side wall and the sealing portion 12, and the sealing element 5 is arranged in the gap. The highest point of the boss 21 is higher than that of the sealing portion 12, so that the gap between the large gland 1 and the small gland 2 is located on the side of the boss 21, and the gap does not face the waste winding area, thereby effectively reducing the possibility of waste slag entering the gap.

[0022] The small gland 2 is provided with a detection block 10 for detecting the rotating speed of the small gland 2, the large gland 1 is connected with a speed sensor 31, the speed sensor 31 can effectively obtain the specific value of the rotating speed of the small gland 2 through the detection block 10, the speed sensor 31 is connected with a communication module, the speed is transmitted to the staff through the communication module, and whether the first bearing 6 is stuck is determined according to the fast or slow of the rotating speed of the small gland 2. The large gland 1 is provided with an oil inlet 32, so that the lubricating oil can be added through the oil inlet 32. The bearing seat outer sleeve 3 is annular, the bearing seat inner sleeve 4 is annular, the bearing seat inner sleeve 4 is located inside the bearing seat outer sleeve 3, and the bearing seat inner sleeve 4 and the bearing seat outer sleeve 3 have a gap, and the first bearing 6 and the second bearing 7 are arranged in the gap.
