Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of slab continuous casting, and particularly relates to a novel segmented roller connection structure. Background Art
[0002] A water cooling channel is set in the middle of the slab segmented continuous casting roller. The water channel between the two sections needs to be connected using a connecting structure. The water channel between the two segmented rollers is connected by a transition core sleeve, and the adjacent bearing seats are fixed with bolts;
[0003] The original free rollers were designed with a segmented structure, that is, the water channel between adjacent rollers was connected by a transition core sleeve and a sealing ring. During transportation, this structure caused the two adjacent roller sleeves to be unable to be fixed synchronously, resulting in the roller sleeve shaking and the sealing ring at the core sleeve deforming, causing water leakage, resulting in poor roller cooling, and thus affecting the roller's service life.

[0009] Furthermore, a receiving groove is provided at the end of the roller, a bearing is fixedly installed inside the receiving groove, and the bearing seat is provided on the outside of the bearing.
[0010] Furthermore, a stacking ring is provided inside the accommodating groove, and an oil seal is provided at the connection between the bearing seat and the stacking ring.
[0011] Furthermore, a dust cover is provided between the two groups of bearing seats, and a second sealing ring is provided between the dust cover and the bearing seat.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.
[0022] Example 1: See Figure 1-4 , a new type of segmented roller connection structure of this embodiment includes two groups of bearing seats 11 arranged at the connection of the roller 10, the bearing seats 11 are installed with the roller 10, the bottoms of the two groups of bearing seats 11 are fixedly connected with coaxial blocks 12, and an adjusting block 13 is provided between the two groups of coaxial blocks 12. The two groups of coaxial blocks 12 and the interiors of the adjusting block 13 are provided with screw holes, and the adjusting block 13 is inserted into the gap between the two groups of coaxial blocks 12 so that the screw holes are aligned. The two groups of coaxial blocks 12 are screwed into the screw holes and fixedly installed by bolts. The bolts are used to fix them in the screw holes, thereby fixing the positions of the two groups of coaxial blocks 12, so that the bearing seats 11 remain fixed, and the gap between the two groups of coaxial blocks 12 is filled by the adjusting block 13 to avoid loose fixation due to the gap between the two groups of coaxial blocks 12;
[0023] A connecting groove 20 is provided at one end of the roller 10, and an annular groove 21 is provided on the inner wall of the connecting groove 20. A first sealing ring 22 is provided inside the annular groove 21, and a core sleeve 23 is provided inside the connecting groove 20. The roller 10 is made of carbon steel. By providing the annular groove 21 on the connecting groove 20 of the roller 10, the roller 10 is made of carbon steel, which is easy to cut during turning and not prone to vibration marks, thereby ensuring sealing. The core sleeve 23 is made of stainless steel, and no annular groove is provided on the stainless steel core sleeve 23, thereby avoiding tool vibration marks at the bottom of the groove during processing on the stainless steel, thereby affecting sealing.
[0024] See Figure 1-3 The end of the roller 10 is provided with a receiving groove 30, and a bearing 31 is fixedly installed inside the receiving groove 30. The bearing seat 11 is sleeved on the outside of the bearing 31, and the bearing seat 11 supports the connection between the roller 10 and the bearing 31.
[0025] See Figure 2-3 A stacking ring 32 is provided inside the accommodating groove 30, and an oil seal 33 is provided at the connection between the bearing seat 11 and the stacking ring 32. The stacking ring 32 and the oil seal 33 are provided to ensure that the lubricating oil inside the bearing seat 11 has better sealing performance, avoid leakage, and provide the bearing 31 with a good working environment.
[0026] See Figure 2-3 A dust cover 34 is provided between the two sets of bearing seats 11, and a second sealing ring 35 is provided between the dust cover 34 and the bearing seat 11. The dust cover 34 and the second sealing ring 35 seal the two sets of bearing seats 11 to prevent lubricating oil leakage.
[0027] Beneficial effects:
[0028] 1. Install the bearing seat 11 and the roller 10, then insert the adjusting block 13 into the gap between the two groups of coaxial blocks 12, align the screw holes, and then use bolts to fix them in the screw holes, thereby fixing the positions of the two groups of coaxial blocks 12 and keeping the bearing seat 11 fixed; fill the gap between the two groups of coaxial blocks 12 by the adjusting block 13, and when the two groups of coaxial blocks 12 are fixed by bolts, the two adjacent middle bearing seats 11 can be firmly fixed together, avoiding the gap between the two groups of coaxial blocks 12. The loose fixation can avoid deformation of the core sleeve due to shaking during transportation, thereby avoiding water leakage.
[0029] 2. By setting an annular groove 21 on the connecting groove 20 of the roller 10, the roller 10 is made of carbon steel, which is easy to cut during turning and is not prone to chatter marks, thereby ensuring sealing. No annular groove is set on the stainless steel core sleeve 23, which can avoid tool chatter marks on the groove bottom during processing on stainless steel, thereby affecting sealing.
[0030] Example 2: Example 2 is a further improvement based on Example 1. The first sealing ring 22 is a Y-shaped sealing ring. The Y-shaped sealing ring has a larger elastic deformation range than the circular sealing ring. After the internal core sleeve 23 has a certain deviation, the deformation of the Y-shaped sealing ring can also maintain a good sealing effect, thereby avoiding leakage of the coolant flowing through the connecting groove 20.
