[0002] Thrust bearings include thrust ball bearings and thrust roller bearings. Thrust ball bearings are further divided into thrust ball bearings and thrust angular contact ball bearings. They are composed of washers with raceways, balls and retainer assemblies. The raceway ring that matches the shaft is called the shaft ring, and the raceway ring that matches the outer shell is called the seat ring. For bidirectional bearings, the middle ring matches the shaft. Some thrust bearings may be misaligned during rotation.

[0003] At the same time, the application number is CN202320570111.0, which is a plane thrust bearing that is easy to install. "It includes two seat rings, a shaft ring and four plug rods.

The shaft ring is provided with four second mounting grooves inside, and nuts are fixedly mounted on the opposite sides of the two groups of mounting grooves."

[0004] During use, the thrust tilting pad on the existing thrust bearing has poor stability, and the above-mentioned structure further reduces the stability of the thrust bearing due to the addition of the telescopic spring structure. During long-term use and operation, the thrust bearing will be subjected to excessive pressure, the thrust pad position will gradually shift, and the operating stability will decrease.

[0005] Therefore, a new thrust bearing installation structure is proposed to solve the above problems. Utility Model Content

[0013] Preferably, the side walls of the thrust washer and the bearing gear ring are grooved, and the connecting ring is embedded in the grooves of the thrust washer and the bearing gear ring.

[0014] Preferably, the spherical pad is located between the thrust washer and the upper balancing block.

[0015] Preferably, there are two connecting rings and a positioning piece is detachably connected between the two connecting rings.

[0016] Preferably, the thrust washer is placed between two adjacent limit blocks.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The utility model places an upper balancing block and a lower balancing block in a gear ring, and a thrust tilting pad is placed on the end face of the gear ring.
