Description

Technical Field

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

[0002] A continuous casting machine is a production equipment that continuously casts high-temperature molten steel into ingots with a certain cross-sectional shape and certain size specifications. The continuous casting machine is equipped with high-temperature bearings. High-temperature bearings refer to bearings with an operating temperature higher than 120°C. They are mainly used in aviation jet engines, atomic reactors, X-ray tubes, semiconductor component manufacturing equipment, and various melting and plating equipment.

[0003] The inventor discovered in his daily work that during use, the sealing ring of the equipment did not fit tightly against the outer ring, which could easily cause the sealing ring to fall off during the rotation of the bearing. In order to solve the problem of the sealing ring and the outer ring not fitting tightly, the prior art uses pasting. However, after long-term use, the viscosity of the sealing ring decreases and it is easy to fall off, exposing the ball bearings, which in turn causes equipment failure. Utility Model Content

[0004] The utility model aims to solve the defect that the sealing ring and the outer ring are not closely fitted in the prior art, and proposes a new type of high temperature bearing for a continuous casting machine.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of high-temperature bearing for a continuous casting machine, comprising an outer ring and a reinforcement device, the inner wall of the outer ring is installed with an inner ring, the surface of the outer ring is installed with steel balls, the surface of the outer ring is provided with a sealing ring, the reinforcement device is arranged on one side of the outer ring, the reinforcement device comprises an auxiliary plate, the auxiliary plate is fixedly connected to the sealing ring, one side of the auxiliary plate is fixedly connected with an annular plate, the surface of the annular plate is provided with a hole 1, a fixing rod is arranged on the side of the outer ring close to the annular plate, a round block is installed on the surface of the fixing rod, a friction pad is arranged on the side of the fixing rod close to the round block, and a pressing plate is fixedly connected to one side of the round block. By arranging the reinforcement device, it is convenient to reinforce the sealing ring, the situation of the sealing ring falling is reduced, and the safety of the equipment is increased.

[0006] Preferably, a card slot is provided on one side of the annular plate close to the pressing sheet, and the pressing sheet is snap-connected with the card slot. By setting the pressing sheet, when in use, the pressing sheet abuts against the annular plate, which facilitates the positioning of the sealing ring, increases the stability of the equipment, and facilitates use.

[0007] Preferably, the longitudinal section of the pressing sheet is set in an "L" shape, and there are two auxiliary plates, which are set in mirror symmetry. By setting the auxiliary plates, it is convenient to position the sealing ring, which increases the stability of the equipment and reduces the difficulty of operating the equipment.

[0008] Preferably, an ejection device is provided on the side of the outer ring close to the auxiliary plate, and the ejection device includes a support plate, and the support plate is sleeved with a fixing rod. A circular groove is provided on the side of the outer ring close to the support plate, and the fixing rod is fixedly connected to the inner wall of the circular groove. A clamping block is fixedly connected to one side of the support plate. By providing the ejection device, the sealing ring can be quickly disassembled, the stability of the equipment is increased, and the difficulty of operating the equipment is reduced.

[0009] Preferably, there are two card blocks, and the two card blocks are arranged in a mirror-symmetrical manner. By arranging the card blocks, when in use, the card blocks are easy to cooperate with the support plate for lifting, which increases the stability of the equipment and facilitates use.

[0010] Preferably, a groove one is provided on one side of the outer ring close to the clamping block, and the clamping block is clamped with the groove one on one side of the outer ring. By setting the clamping block, when in use, the clamping block and the groove one abut against each other, which is convenient for limiting the movement of the support plate, increasing the stability of the equipment and facilitating use.

[0011] Preferably, a gasket is fixedly connected to the inner wall of the circular groove, a pressure spring is fixedly connected to the surface of the gasket, and the side of the pressure spring away from the gasket is fixedly connected to the support plate. By setting the pressure spring, when in use, the pressure spring generates elastic force to squeeze the support plate to move, thereby increasing the stability of the equipment and facilitating use.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The utility model provides a reinforcing device and an ejecting device. When in use, the sealing ring is fitted with the outer ring. At this time, the fixing rod passes through the annular plate, and then the round block is rotated. The round block drives the pressing piece away from the slot. At this time, the sealing ring is difficult to move. At the same time, the friction pad increases the friction force on the round block. The rotating round block drives the pressing piece to correspond to the slot. At this time, the support plate loses its restraint, and the pressure spring generates elastic force to squeeze the support plate to eject the annular plate and the auxiliary plate. At this time, the sealing ring can be removed. By providing the utility model, it is convenient to reinforce the sealing ring, which reduces the situation where the sealing ring is easy to fall off, increases the safety of the equipment, reduces the failure rate of the equipment, facilitates the protection of the steel balls, increases the service life of the equipment, and is convenient for users to quickly disassemble the sealing ring when repairing the steel balls, thereby increasing the stability of the equipment.
