DECOUPLING DESIGN METHOD FOR SEALING AND BEARING STRUCTURE, AND SUPPORT STRUCTURE

WIPO Patent Application WO/2024/050987

A1

Disclosed is a decoupling design method for a sealing and bearing structure, at least comprising the following steps: S01, performing decoupling of bearing and sealing requirements on a composite position requiring sealing and bearing; S02, designing a bearing structure: separately designing a bearing structure form at the composite position, and implementing effective bearing by means of an independent mechanical connecting structure; and S03, designing a sealing structure: after step S02 is completed, separately designing a sealing structure form at the composite position, designing, by using a thin-wall joint, the sealing structure wrapping the bearing structure, and implementing sealing at the composite position by means of welding. According to the present invention, decoupling design is performed on the composite position that need to satisfy both bearing and sealing requirements, the mechanical connecting structure is firstly designed to satisfy the bearing requirement at the composite position, and then the composite position and the mechanical connecting structure are sealed by means of the sealing structure, thereby guaranteeing that a designed low-temperature device has good bearing and sealing functions at the composite position. Also disclosed is a support structure.
