Problems solved by technology
[0002] When the engine is assembled, it involves the docking of multi-stage stator casings. Due to the tolerances in the machining process of the stator casings at each stage, in order to reduce the influence of the cumulative tolerance of the stator casings at all levels, it is mostly between the stator casings that are docked at two adjacent stages. Annular gaskets of corresponding thickness are set to balance the tolerances in the processing of the two-stage stator casing, but the tolerances between the stator casings at all levels and the tolerances of the stator casings at each level are not completely consistent. The thickness of the gasket needs to be calculated, selected, and manufactured according to the actual situation. The process is cumbersome and inefficient, which makes the engine assembly cycle longer
