TECHNICAL FIELD
[0001] The utility model relates to the field of bearing seat, especially a continuous casting machine casting billet roller bed bearing seat. BACKGROUND
[0002] The continuous casting machine uses a plurality of continuous casting rollers to support and guide in the production process, and the continuous casting rollers are installed on the corresponding roller bed bearing seat.
[0003] The service life of the continuous casting machine casting billet roller bed bearing seat in the prior art is relatively low, mainly because the bearing in the bearing seat is prone to failure, and the main reasons are as follows: first, the bearing seat is close to the high-temperature casting billet, and the lubricating grease of the bearing seat is prone to carbonization, so that the bearing in the bearing seat cannot be fully lubricated and cooled, and is easily damaged; second, in the continuous casting production process, a large amount of dust particles are generated, which easily enter the bearing seat through the gap between the continuous casting roller and the end cover of the bearing seat, and then adhere to the bearing in the bearing seat, aggravating the wear and failure of the bearing. SUMMARY
[0004] The utility model discloses a kind of continuous casting machine casting billet roller bed bearing seat, which can effectively prevent dust and has better cooling effect and long service life.
[0005] The utility model discloses a kind of continuous casting machine casting billet roller bed bearing seat, which can effectively prevent dust and has better cooling effect and long service life.
[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: the bearing housing provided by this utility model has a better cooling and sealing effect and a longer service life; specifically, while water cooling is provided by a cooling box, heat sinks are also provided on the outside of the end cover, and air cooling rings are used to air cool the heat sinks, thereby achieving a better cooling effect; on the other hand, due to the diversion and guiding effect of the diversion ring, while the air cooling rings air cool the heat sinks, a portion of the cold air is also blown axially toward the continuous casting roll, thereby reducing the possibility of dust particles entering the bearing housing.
[0007] Furthermore, the outer side of the end cap is provided with a spray ring located outside several heat sinks, and the spray ring is provided with several wide-angle nozzles that are symmetrically distributed with their openings facing inward. This design can further accelerate the heat dissipation of the heat sinks, thereby achieving a better cooling effect.
[0008] Furthermore, the outer side of the aforementioned cooling box is provided with a thermally conductive layer made of thermally conductive adhesive. This design allows for a tighter fit between the cooling box and the cooling tank, resulting in better heat conduction between them.
[0009] Furthermore, a dustproof sealing ring is provided at the outer end of the aforementioned mandrel through hole. This design further improves the sealing performance of the bearing housing.
[0010] Furthermore, the interior of the aforementioned cooling box is equipped with several baffles arranged in a labyrinthine pattern along its circumference. This design extends the flow path of the cooling water within the cooling box, thereby allowing for more thorough contact between the water and the interior of the bearing housing and absorbing more heat.
[0011] Furthermore, the connection between the end cap and the bearing housing body is provided with centrally symmetrically distributed connecting holes, and connecting bolts are installed in the connecting holes. This design is simple in structure, reliable in connection, and convenient in assembly and disassembly. Attached Figure Description

[0018] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.
[0019] Combined with appendix Figures 1-5 As shown, a continuous casting machine billet roller bearing housing includes a bearing housing body 1, on which a bearing mounting hole 1a is provided, and an annular cooling groove 1b is provided on the outer side of both ends of the bearing mounting hole 1a; a bearing 2, which is disposed in the bearing mounting hole 1a; and two end covers 3, which are detachably disposed on the left and right sides of the bearing housing body 1, respectively; each end cover 3 includes a cooling box 4 disposed on its inner side and detachably installed in the corresponding cooling groove 1b, and also includes an air-cooling ring 6 disposed in the middle of the outer side of the end cover 3, and further includes a cooling box 4 disposed on the outer side of the air-cooling ring 6. The cooling box 4 has several centrally symmetrically distributed heat sinks 7; a spindle through hole 5 is provided at the center of the left end cover 3; several centrally symmetrically distributed air-cooling nozzles 6a with outward openings are provided on the air-cooling ring 6; the inner ring of the heat sinks 7 on the left is provided with a flow-dividing ring 7a with a right-angle cross-section, and the air-cooling nozzles 6a are directly opposite the corners of the flow-dividing ring 7a; a partition 4a is provided at the lower end of the interior of the cooling box 4; the end cover 3 is provided with a water inlet 9 and a water outlet 10 that communicate with the interior of the cooling box 4; the connection points between the water inlet 9 and the water outlet 10 and the cooling box 4 are located on both sides of the partition 4a.
[0020] It should be noted that the aforementioned air-cooled ring 6 is connected to any air source, which provides cold air, such as an air compressor.
[0021] The outer side of the aforementioned end cover 3 is also provided with a spray ring 8 located outside a plurality of heat sinks 7. The spray ring 8 is provided with a plurality of wide-angle nozzles 8a with openings facing inward and centrally symmetrically distributed. It should be noted that the wide-angle nozzles 8a have a larger spray angle and a wider spray range. The spray ring 8 is connected to any water source, which provides cooling water, such as a water tank with a water pump.
[0022] The outer side of the aforementioned cooling box 4 is provided with a heat-conducting layer made of thermally conductive adhesive.
[0023] A dustproof sealing ring 5a is provided on the outer end of the aforementioned mandrel through hole 5.
[0024] The interior of the aforementioned cooling box 4 is provided with several baffles 4b arranged in a labyrinthine pattern along its circumference.
[0025] The connection between the end cap 3 and the bearing housing body 1 is provided with centrally symmetrically distributed connecting holes 11, and connecting bolts 11a are provided in the connecting holes 11.
[0026] During cooling operation, cooling water enters the cooling tank 4 from the inlet 9; then it gradually passes around the cooling tank 4 via the baffle 4b, making full contact with it; finally, carrying the heat absorbed by the cooling tank 4 from the bearing housing body 1, it flows out from the outlet 10.
[0027] At the same time, the spray ring 8 sprays cooling water mist onto the heat sink 7 through the wide-angle nozzle 8a, and the cooling air in the air-cooling ring 6 is blown onto the heat sink 7 through the air-cooling nozzle 6a, causing the water mist on the heat sink 7 to evaporate quickly and absorb heat, thereby further improving the cooling effect.
[0028] The cooling air blown out from the air-cooling nozzle 6a on the left side of the air-cooling ring 6 is directed by the diversion ring 7a. Part of the cooling air is blown towards the heat sink 7 for air cooling, while another part of the cooling air is blown axially towards the continuous casting roll, thereby reducing the possibility of dust particles entering the bearing housing along the gap between the continuous casting roll and the bearing housing.
