Tapered roller thrust bearing with taper hole window isolation block structure

The invention belongs to the technical field of bearing assembling and manufacturing, and particularly relates to a thrust tapered roller bearing with an isolation block structure, the thrust tapered roller bearing comprises a seat ring, a shaft ring and a plurality of isolation blocks, the plurality of isolation blocks are sleeved to form a circumferential structure to be assembled between the seat ring and the shaft ring, the isolation blocks and rollers are arranged in a one-to-one correspondence mode, and tapered pockets are formed in the isolation blocks. And the rollers are assembled in the conical pockets. A large retainer is divided into independent isolation block structures, each independent isolation block structure is machined into a standard part, the size consistency is good, a retainer circumferential structure is formed after sleeving, the total gap is within a reasonable range, the use performance of a bearing can be met, and meanwhile the manufacturing difficulty and cost of the bearing reta
