Description

Technical Field

[0001] The utility model belongs to the technical field of continuous casting machines and accessories thereof, in particular to a spherical self-aligning roller dedicated to continuous casting machines. Background Art

[0002] The continuous casting machine is the most common equipment in the steel casting process. The high-temperature molten steel is continuously poured into the casting mold through the continuous casting machine. The casting can be taken out from the mold after it is cooled and formed. The most important accessory of the continuous casting machine is the self-aligning roller. The self-aligning roller makes the operation of the continuous casting machine smoother, thereby improving the continuous pouring efficiency of the molten steel.

[0003] A Chinese patent application (or patent) with the announcement number CN218118337U discloses a spherical self-aligning roller bearing for continuous casting machines, including an outer ring, a plurality of groups of mounting grooves are evenly arranged at a non-circular position at one end of the outer ring, springs are symmetrically arranged on both sides of the mounting groove, a clamping block is arranged on one side of the spring, sealing covers are symmetrically arranged at both ends of the outer ring, a plurality of groups of insert blocks are evenly arranged at one end of the sealing cover, and the insert blocks and the clamping blocks are adapted to each other; the utility model enables the sealing cover to be quickly disassembled through the cooperation of the spring, the clamping block and the mounting groove, and it is convenient to replenish the lubricating oil inside the bearing after it evaporates, and the disassembly operation is simple, and no tools are required, and the rollers can be disassembled separately through the cooperation of the sealing ring, the limit block, the clamping groove and the connecting groove, which is convenient for replacing the rollers, and also convenient for subsequent assembly of the bearings, thereby reducing the difficulty of producing the bearings.

[0004] The above-mentioned spherical self-aligning roller bearing for continuous casting machine has a sealing cover on its outer ring, and the sealing cover is assembled on the outer wall of the outer sleeve through a spring clamp block, so as to achieve the effect of quick disassembly and assembly of the sealing cover. However, this assembly effect is limited by the strength of the clamp block itself. When the self-aligning roller is pressed too much, the clamp block on the sealing cover is subjected to greater pressure, and the thinner clamp block is more likely to bend and be damaged, which makes it difficult to remove the sealing cover, and thus causes the problem that the lubricant is difficult to replenish on the self-aligning roller; and a spring is arranged on it, and the clamp block is pushed to move left and right by the spring, and the plug block is clamped and limited by the special shape of the clamp block, so as to achieve the effect of quick assembly, but because the elastic performance of the spring is uncontrollable and will be deformed due to external force, when the clamp block or the plug block is subjected to force, the springs on both sides thereof will be pushed to change in displacement, and when it is displaced, the plug block will be separated from the clamp block, so as to cause the problem that the entire self-aligning roller is naturally separated. For this reason, we provide a spherical self-aligning roller for continuous casting machine to solve the above-mentioned problems. Utility Model Content

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] Embodiment 1, please refer to Figures 1-5 , the present invention is a special spherical self-aligning roller for a continuous casting machine, including an outer sleeve ring 1. The quick disassembly and assembly of the self-aligning roller can be realized by using the cooperation of the outer baffle 101, the outer retaining ring 2, the outer clamping plate 201 and the fixing stud 3.

[0030] Specifically, an outer baffle 101 is provided on the outer wall of the outer sleeve ring 1, and a baffle groove 102 is arranged inside the outer baffle 101. An insertion groove 103 is also provided on the outer sleeve ring 1 between the outer baffles 101, and the insertion groove 103 is communicated with the baffle groove 102. A closing groove 104 is further provided inside the baffle groove 102. At the same time, a ball groove I 105 is provided inside the closing groove 104 and in the outer sleeve ring 1.

[0031] Further, the baffle groove 102 in the outer sleeve ring 1 cooperates with the outer wall of the outer clamping plate 201, and the insertion groove 103 also cooperates with the side wall of the outer clamping plate 201. At the same time, the outer clamping plate 201 and the outer baffle 101 are also fixedly connected by fixing studs 3. The outer clamping plate 201 is welded to the outer side wall of the outer retaining ring 2. Meanwhile, a closing plate 7 is fitted on the inner side wall of the outer retaining ring 2, and the outer wall of the closing plate 7 cooperates with the inner wall of the closing groove 104. A second ball groove 701 is formed on the inner wall of the closing plate 7. A ball 6 is clamped in the annular chamber formed by the first ball groove 105 and the second ball groove 701, and an inner sleeve ring 4 is arranged outside the ball 6.

[0032] The operation process of this embodiment is as follows: during use, the ball 6 is placed in the first ball groove 105, and then the flanged side of the inner sleeve ring 4 is snapped into the first ball groove 105. Then, the closing plate 7 is covered outside the ball 6, and the side of the second ball groove 701 on the closing plate 7 faces the ball 6. After removing the outer retaining ring 2, the outer clamping plate 201 on the outer retaining ring 2 is aligned with the insertion groove 103 on the outer sleeve ring 1, and the outer retaining ring 2 is pressed inward, so that the outer clamping plate 201 continuously moves downward along the insertion groove 103 to the position where the baffle groove 102 is located. Then, hold the outer retaining ring 2 and rotate it, and the outer clamping plate 201 will be inserted into the baffle groove 102 along the insertion groove 103. When the outer clamping plate 201 completely enters the baffle groove 102, stop rotating the outer retaining ring 2. At this time, the outer retaining ring 2 can press the closing plate 7 to always be in the closing groove 104. At the same time, due to the existence of the outer baffle 101, the outer clamping plate 201 cannot directly pop out from the side. Then, align the fixing stud 3 with the fixing hole 101a, hold the end of the fixing stud 3 welded with the rotating handle and rotate the fixing stud 3, and the fixing stud 3 can be screwed through the fixing hole 101a and the outer clamping plate 201 into the rear side wall of the baffle groove 102, thus completing the assembly of the spherical roller. The structure is simple and convenient for disassembly and assembly.

[0033] Example 2, please refer to Figure 6 , on the basis of Example 1, an oil passage 106 is provided on the first ball groove 105 on the outer sleeve ring 1 for placing the ball 6. The other end of the oil passage 106 penetrates through the outer wall of the outer sleeve ring 1, and thus lubricating oil can be replenished to the ball 6 through this end, realizing the replenishment of lubricating oil without disassembling the spherical roller.

[0034] Specifically, an oil passage 106 is formed on the side wall of the outer sleeve ring 1. The oil passage 106 is bent, and one end is located outside the outer sleeve ring 1, while the other side of the oil passage 106 penetrates through the side wall of the outer sleeve ring 1 and extends to the inner wall of the first ball groove 105. At the same time, a sealing assembly 5 is embedded on the outer sleeve ring 1. The sealing column 502 in the sealing assembly 5 is fixedly connected to the outer wall of the outer sleeve ring 1 through a spring 501.

[0035] Further, an installation hole 107 is formed in the outer wall of the outer sleeve ring 1, and one end of a spring 501 is fixedly connected to the inner wall of the installation hole 107. A sealing sleeve 106a is fixedly installed on the inner wall of one end of the oil passage 106 located outside the outer sleeve ring 1, and the sealing sleeve 106a is threadedly connected to a sealing column 502.

[0036] The operation process of this embodiment is as follows: After the assembly of the spherical roller is completed, hold the sealing column 502 and extend the spring 501 at its rear end. At this time, the sealing column 502 disengages from the installation hole 107. Then, align the sealing column 502 with the sealing sleeve 106a on the oil passage 106, and rotatably lock the sealing column 502 into the sealing sleeve 106a to block the oil passage 106 and prevent external dust from entering the space where the ball 6 is located. When lubricating oil needs to be replenished, reverse the above steps to expose the oil passage 106. Align the oil bottle of the lubricating oil with the oil passage 106 and squeeze the oil bottle to squeeze the lubricating oil in it into the oil passage 106. At the same time, since the oil passage 106 is communicated with the space where the ball 6 is located, the lubricating oil then enters the space where the ball 6 is located along the oil passage 106 to achieve the effect of lubricating the ball 6 therein. After the replenishment of the lubricating oil is completed, close the oil passage 106 again.
