Technical Field

[0001] The utility model relates to the technical field of thrust roller bearing assembly, in particular to an installation tool for a raceway of a thrust roller bearing. Background Art

[0002] A thrust roller bearing is an important mechanical component, mainly used to bear the combined axial and radial loads of a shaft mainly subjected to axial loads. Thrust roller bearings are widely used in various mechanical equipment that need to bear axial loads, such as heavy machine tools, high-power marine gearboxes, oil drilling rigs, vertical motors, etc. In these applications, thrust roller bearings can effectively support the rotating shaft, reduce friction, and improve mechanical efficiency and reliability. During the production of some large thrust roller bearings, when assembling the raceway into the bearing housing, since there is no lifting point on the raceway, it is very difficult to position the raceway into the bearing housing during the assembly process. The assembly process is relatively cumbersome, with high labor intensity and low assembly efficiency.

[0003] Therefore, it is necessary to design an installation tool for a thrust roller bearing raceway to solve the above problems. Summary of the Utility Model
