A rack 3 is movably inserted in the outer shell 1 at one side of the assembly hole 4, and the rack 3 is meshed with the bottom end of the gear shaft 2; the steering wheel is used for driving the gear shaft 2 to rotate and driving the rack 3 to rotate in the process of driving the gear shaft 2 to rotate, so that pull rods connected with the ends of the two ends of the rack 3 are respectively driven to move in the process of driving the rack 3 to move, and the wheels are pulled by the pull rods to deflect in the process of rotating, so that steering is completed. An internal thread 5 is arranged on the inner wall of the assembly hole 4; the gear shaft 2 is sleeved with a positioning bearing, the positioning bearing comprises an inner ring 6, rollers 7 and an outer ring 8, and the rollers 7 are arranged between the outer ring 8 and the inner ring 6 through a retainer 9; the inner ring 6 is connected with the gear shaft 2 in a sleeved mode, external threads 10 are arranged on the circumferential surface of the outer ring 8, and the outer ring 8 is in threaded connection with the assembly hole 4 through matching of the external threads 10 and the internal threads 5. Because the outer ring 8 of the positioning bearing is in threaded connection with the assembly hole 4 through the matching of the external thread 10 and the internal thread 5, the outer ring 8 can directly enter the assembly hole 4 through the threads, and then the outer ring 8 is screwed into the outer shell 1, so that the positioning bearing is arranged in the assembly hole 4, namely the positioning bearing is arranged on the outer shell 1. Since the positioning bearing is mounted by the screw thread, the outer ring 8 can be screwed out of the outer shell 1 by reversing the outer ring 8, and the positioning bearing can be taken out of the outer shell 1, so that the positioning bearing can be conveniently detached. The positioning bearing is directly arranged on the outer shell 1 through the threads of the outer ring 8, and the outer ring 8 is not required to be fixed by using the pressing screw plug skill, so that the use of one part can be effectively reduced, the production cost of the steering gear assembly can be reduced, the weight of the steering gear assembly can be effectively reduced, and the light-weight requirement of the steering gear assembly can be realized. Meanwhile, the space occupied by the compression screw plug can be reduced through the direct locking of the positioning bearing, the space occupation along the axial direction of the gear shaft can be effectively reduced, the position occupation of the gear shaft is further effectively reduced, and the arrangement of the steering gear assembly in an engine cabin is more facilitated.
The top of the outer ring 8 is provided with an outer ring nut 11 for screwing the outer ring 8, so that a tool (a spanner or a sleeve) can conveniently screw the outer ring nut 11 through taking the outer ring nut 11 as a stress point, and then the outer ring 8 is driven to rotate through the outer ring nut 11.
The outer ring 8 below the external thread 10 is connected with the assembly hole 4 in a sliding and inserting manner, and the purpose is to limit the bottom end head of the outer ring 8 through the inner wall of the assembly hole 4, so that the outer ring 8 is guided in the installation process, and the outer ring 8 is not easy to deviate in the installation process; on the other hand, the outer ring 8 is limited, so that the outer ring 8 is prevented from swinging, and the threads are prevented from loosening.
The assembly hole 4 is provided with a positioning shoulder 12, the positioning shoulder 12 is in abutting connection with the bottom end of the outer ring 8, so that the interaction force between the external thread 10 on the outer ring 8 and the internal thread 5 on the assembly hole 4 is increased through the reaction force of the positioning shoulder 12 on the outer ring 8 in the process of screwing the outer ring 8, and the friction force between the threads is further increased, so that the outer ring 8 is locked in the assembly hole 4, the outer ring 8 is not easy to loosen from the assembly hole 4, and the connection state of the positioning bearing and the outer shell 1 is maintained.

Because the outer ring 8 is inserted into the assembly hole 4 along the central axis direction of the assembly hole 4, the outer ring 8 is not easy to deviate, and therefore, the outer thread 10 is not easy to deviate when being meshed with the inner thread 5. After the external thread 10 is in contact with the internal thread 5, the outer ring nut 11 is screwed by a tool, so that the outer ring 8 is driven to rotate, the outer ring 8 is gradually screwed into the assembly hole 4 by the thread, and the positioning bearing is further installed in the outer shell 1. During the process of screwing the outer ring 8 into the assembly hole 4, after the outer ring 8 contacts with the positioning shoulder 12 of the assembly hole 4, the outer ring 8 is continuously forced, and the friction force between the external thread 10 and the internal thread 5 is increased through the interaction of the outer ring 8 and the positioning shoulder 12, so that the outer ring 8 is locked in the assembly hole 4, and the positioning bearing is locked on the outer shell 1.
An adjusting hole is formed in the outer shell 1 on one side of the rack 3, a supporting seat 13 is inserted into the adjusting hole, the inner side end face of the supporting seat 13 is in sliding connection with the rack 3, an adjusting plug screw 14 is arranged in the adjusting hole on the outer side of the supporting seat 13 in a threaded mode, and a compression spring 15 is arranged between the adjusting plug screw 14 and the supporting seat 13.
