Problems solved by technology
[0004] The existing bearing outer ring installation often adopts the method of human judgment to align the relative positions of the anti-rotation teeth 92 and the anti-rotation groove 93. However, the inventors found that the position deviation is prone to occur through the method of human judgment, resulting in the failure of the bearing outer ring 91. It is smoothly installed into the bearing mounting seat 90. In addition, the pushing process of the bearing outer ring 91 is also difficult to ensure vertical smoothness, and repeated installation is required, which is inefficient
Sometimes even during multiple installations, due to the long assembly time, the bearing mounting seat 90 cools and shrinks, causing the bearing outer ring 91 to be stuck on the bearing mounting seat 90, and the bearing mounting seat 90 needs to be reheated
Such repetition leads to low installation efficiency, and the installation process is time-consuming and laborious

The purpose of the present invention is to provide a bearing outer ring assembly tool, which can improve the assembly efficiency of the bearing outer ring. The bearing outer ring assembly tooling for achieving the aforementioned purpose includes a positioning and guiding device for assembling the bearing outer ring and a force application component. The positioning and guiding device for assembling the bearing outer ring includes a fixing seat and a guiding rod. Through the fixed seat, and supported on the fixed seat by the elastic member. The guide rod and the fixed seat jointly clamp the outer ring of the bearing to form an assembly. The guide portion of the guide rod can be aligned with the anti-rotation groove, and has a shape corresponding to the anti-rotation groove, so as to allow the guide portion to be inserted downward into the anti-rotation groove to cooperate with it, so as to guide the axial movement of the assembly.
Description
technical field [0001] The invention relates to a bearing outer ring assembly tool. Background technique [0002] The stator and the rotor in the aeroengine turbine are connected by bearings, wherein the five-point bearing outer ring of the bearing is installed on the turbine rear casing in the turbine stator. [0003] Such as figure 1 A schematic cross-sectional view of the turbine rear casing is shown, figure 2 It is a three-dimensional schematic diagram of the turbine rear case. A bearing mounting seat 90 is arranged on the turbine rear case 9, and the bearing outer ring 91 is mounted on the bearing mounting seat 90 by interference fit. In order to prevent relative rotation between the bearing outer ring 91 and the bearing mounting seat 90 during the working process, anti-rotation teeth 92 are provided at the end of the five-point bearing outer ring 91, and anti-rotation grooves 93 are correspondingly provided on the bearing mounting seat 90 . During installation, i...
