Embodiment approach

[0031] As a specific embodiment, it also includes a method for stabilizing the connection of the engine stator, first positioning the stop protrusion 6 on the first stator casing 1 and the stop groove 7 on the second stator casing 3 , the first bolt hole 4 on the first stator casing 1 and the bolt hole on the second stator casing 3 are coaxial, and then screw the screw 10 part of the precision bolt 2 into the first bolt hole 4 and the second bolt In the hole 5, finally screw in the nut 11 to fit closely with the second stator casing 3 to complete the installation.

[0032] By adopting the method of notch positioning first and then screw hole processing, high-precision machining and high coaxiality of the first bolt hole 4 and the second bolt hole 5 can be achieved, and the precision bolt 2 installed in this way can be aligned with the first stator machine. The stable cooperation between the casing 1 and the second stator casing 3 ensures the continuity and stable operation of ...

Abstract

The invention relates to the field of stator case assembly design, in particular to an engine stator stable connection structure which comprises a first stator case and a second stator case arranged correspondingly, a first bolt hole is formed in the first stator case, and a second bolt hole is formed in the second stator case. Accurate positioning of the first stator casing and the second stator casing is guaranteed by tightly attaching the lower surface of the spigot protrusion on the first stator casing and the bottom face of the spigot groove in the second stator casing during installation, and then high-precision and high-coaxiality machining of the machined first bolt hole and the machined second bolt hole can be achieved. Therefore, precise matching of the precise bolt, the first bolt hole and the second bolt hole is achieved, when an engine works, even if the spigot structure is disengaged, reliable work of the first stator casing and the second stator casing can be achieved through the precise bolt, and structural continuity and stable work of the connecting structure are achieved.

Description

technical field [0001] The application belongs to the field of stator casing assembly design, and in particular relates to a stable connection structure and method for an engine stator. Background technique [0002] The ability to maintain the concentricity of the fulcrum of the engine is an important factor affecting the dynamic characteristics of the whole machine structure. At the same time, the concentricity of the fulcrum is a direct reflection of the relative position of the rotor / stator of the engine, which affects the gap distribution of the engine in the state of the whole machine. related to engine performance. In the stator connection structure, it is necessary to design the coaxiality positioning structure according to the overall working environment of the engine to ensure that the coaxiality level of the whole machine after assembly meets the requirements for safe operation and performance maintenance of the engine. figure 1 Because of the existing short bolt-...
