[0002] As a key component widely used in rotating machinery, the thrust bearing plays a crucial role in mechanical operation. Its main functions can be summarized as follows: First, the thrust bearing plays a role in balancing the thrust. In rotating machinery, a large axial thrust is generated when the rotor rotates at high speed. If these thrusts are not effectively balanced, it will cause the rotor to axially move, which will further cause mechanical vibration, reduce the stability of equipment operation, and even may cause equipment damage. The thrust bearing can withstand and balance these axial thrusts through its special structure and design, ensuring the rotor operates stably at the specified axial position.

[0003] Most of the existing thrust bearing tiles are fixed and installed separately by bolts. This makes the disassembly and assembly maintenance of the thrust bearing tile more cumbersome, seriously affecting the use of the thrust bearing.

Through a plurality of water-cooled thrust pad assemblies 2, the axial thrust of the bearing can be borne, and through the fixing assembly 3, the thrust pad assembly 2 can be quickly disassembled and assembled, so as to maintain the thrust pad assembly 2. And under the action of the oil inlet assembly 4, lubricating oil can be quickly injected into the bearing housing 1, so as to melt the thrust pad assembly 2, thus improving the service life of the thrust pad assembly 2.

[0043] Furthermore, as Figure 2 shown, the bearing housing 1 in the preferred embodiment of the present invention further includes an installation groove 11, which is opened on the upper surface of the bearing housing 1; a first sliding groove 12, which is opened on the inner side of the installation groove 11; a second sliding groove 13, which is opened on the upper surface of the bearing housing 1 and the second sliding groove 13 is communicated with the installation groove 11; a plurality of installation holes 14, which are evenly distributed and opened on the outer side of the bearing housing 1, and a plurality of installation holes 14 are all communicated with the installation groove 11; two placement grooves 15, which are symmetrically opened on the front surface of the bearing housing 1; two threaded grooves 16, which are respectively opened on the inner sides of the two placement grooves 15.

[0044] Furthermore, a plurality of oil inlet assemblies 4 are respectively arranged in a plurality of installation holes 14.

[0045] Further, as Figure 3As shown in the figure, the thrust bearing block assembly 2 in the preferred embodiment of the present utility model includes a thrust bearing block body 21, which is arranged inside the installation groove 11, and the thrust disc 5 can be placed on the front surface of the thrust bearing block body 21; a first limiting block 22, which is arranged on the side of the thrust bearing block body 21 away from the installation hole 14, and the first limiting block 22 is located inside the first sliding groove 12; a second limiting block 23, which is arranged on the side of the thrust bearing block body 21 close to the installation hole 14, and the second limiting block 23 is located inside the second sliding groove 13.

[0046] Furthermore, the first limiting block 22 and the second limiting block 23 are respectively in clearance fit with the first sliding groove 12 and the second sliding groove 13.

[0047] In this embodiment, multiple preferred embodiments of the thrust bearing block assembly 2 are given. Through the first limiting block 22 and the second limiting block 23 arranged on the outer side of the thrust bearing block body 21, since the first limiting block 22 and the second limiting block 23 are respectively in clearance fit with the first sliding groove 12 and the second sliding groove 13, when the thrust bearing block body 21 is subjected to an axial thrust, the first limiting block 22 and the second limiting block 23 can respectively be located in the first sliding groove 12 and the second sliding groove 13 for yielding, so that the thrust bearing block body 21 can bear a greater axial thrust.

[0048] Further, as Figure 4 shown, the fixing assembly 3 in the preferred embodiment of the present utility model includes a fixing ring 31, which is detachably arranged inside the second sliding groove 13, and the rear surface of the fixing ring 31 is in contact with the front surface of the second limiting block 23; two connecting blocks 32, which are symmetrically arranged on the outer side of the fixing ring 31, and the two connecting blocks 32 are respectively located in the two placing grooves 15; two fixing bolts 33, which are respectively rotatably arranged inside the connecting blocks 32.

[0049] Furthermore, the two fixing bolts 33 are respectively located inside the two threaded grooves 16, and the outer side of the fixing bolt 33 is threadedly connected with the inner side of the threaded groove 16.

[0050] In this embodiment, multiple preferred embodiments of the fixing assembly 3 are given. After the fixing bolts 33 are screwed out from the threaded grooves 16, the fixing ring 31 arranged between the two connecting blocks 32 can be taken out from the second sliding groove 13, and then a plurality of thrust bearing block bodies 21 can be taken out from the installation groove 11, so that when maintaining or replacing the thrust bearing block body 21, it is more convenient.

The lubricating oil will enter the mounting groove 11 through the oil inlet pipe 41. And under the action of the one-way valve 42, it can prevent the lubricating oil entering the mounting groove 11 from flowing out through other oil inlet pipes 41. Then when the thrust bearing is in use, the thrust pad body 21 will rotate, so that the lubricating oil in the mounting groove 11 will form an oil film on the outside of each thrust pad body 21, thereby improving the service life of the thrust pad body 21.
