Description

Technical Field

[0001] The utility model relates to the technical field of spring bearings, in particular to a multi-structure spring bearing for a continuous casting machine. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Spring bearings are a special type of bearing that combines the elasticity of springs with the supporting function of bearings. Spring bearings are often used in continuous casting machines.

[0003] Prior art, such as the utility model with publication number CN218118352U, discloses a spring bearing for continuous casting machine, including an outer ring, an inner ring is arranged on the inner side of the outer ring, spiral rolling bodies are evenly arranged on the side close to the outer ring and the inner ring, retaining frames are arranged on both sides of multiple groups of spiral rolling bodies, and annular grooves are arranged on both sides of the inner ring of the outer ring and the inner ring; the utility model can realize the sealing function of the spring bearing through the mutual cooperation of annular gears, turntables, rotating rods, through holes, coil springs, clamping blocks, annular grooves, annular grooves and spliced ​​sealing rings, so as to prevent dust driven by external air from entering the interior through the gaps, reduce wear, and at the same time, through annular heat absorbing plates and annular heat dissipating plates The mutual cooperation can effectively improve the cooling work of the spring bearing, reduce the deformation caused by high temperature, and extend its service life. The structural design is simple and reasonable and suitable for promotion, thereby improving the practicability of the spring bearing and solving the following inconveniences encountered in the use of existing spring bearings: most of the existing spring bearings do not have a sealing function, which will cause dust to enter the interior of the bearing due to external air and cause accumulation during use. This will increase the wear of the bearing for a long time, and the existing spring bearings have a poor internal cooling effect. If the cooling work is not performed in time during use, the bearing will be deformed due to high temperature, which will affect its subsequent normal use and reduce the service life of the spring bearing.

[0004] In daily work, it is found that when the above-mentioned spring bearings are in use, the structure is relatively simple, the diameter of the inner ring is fixed, and the inner ring of the bearing can only be placed on a shaft rod of the same size. When installing different shaft rods, it is necessary to purchase suitable bearings again, which increases the cost. It is not suitable for shafts of different sizes or installation requirements, which leads to the problem that the inner ring structure of the existing spring bearings is simple and can only be installed on a shaft rod of one size.

The surface of the snap ring is provided with three groups of grooves for the placement block to pass through. Through the above components, when the clamping member is working, the rotating member drives the snap ring to rotate, and the snap ring can be snapped into the slot on the surface of the placement block to limit the position. When taking it, it only needs to rotate the groove on the surface of the snap ring to the placement block, and the snap ring loses its restraint on the placement block, and it can be taken.

[0008] Preferably, three positioning blocks are fixedly connected to the surface of the rotating part, and three groups of positioning grooves are opened on the surface of the inner ring of the bearing.

The reinforcement blocks are plugged into the inner walls of the reinforcement grooves. Through the above components, after the replacement part is installed, the reinforcement blocks can be inserted into the reinforcement grooves, thereby improving the overall strength of the replacement part.

[0010] Preferably, the positioning assembly includes a bolt, which is threadedly connected to the inner wall of the rotating part, and a positioning hole is opened on the inner wall of the rotating groove. The bolt is inserted into the inner wall of the positioning hole.

The clamping member 27 is plugged into the clamping groove. A positioning component 26 is arranged on the surface of the clamping member 27.

[0024] In this embodiment: the replacement part 21 can be of different diameters, so as to facilitate adaptation to different installation shafts. When replacing, the placement block 23 on the surface of the replacement part 21 can be inserted into the placement groove 28 of the bearing inner ring body 1, and then the clamping member 27 is rotated. The clamping member 27 can cooperate with the clamping groove on the surface of the placement block 23 for preliminary positioning.

The surface of the retaining ring 272 is provided with three groups of grooves for the placement block 23 to pass through.

[0026] In this embodiment: when the clamping member 27 is working, the clamping ring 272 is driven to rotate by the rotating member 271, and the clamping ring 272 can be inserted into the clamping groove on the surface of the placement block 23 to limit the position. When taking it, it is only necessary to rotate the groove on the surface of the clamping ring 272 to the placement block 23, and the clamping ring 272 loses its restraint on the placement block 23, and it can be taken.

[0027] Specifically, three positioning blocks 273 are fixedly connected to the surface of the rotating part 271, and three groups of positioning grooves are opened on the surface of the inner ring body 1 of the bearing.
