摘要：An expansion connection structure and connection method, and an expansion connection asmbly. The expansion connection structure compris an expansion
connection asmbly, a parent component (1), and an attachment component (2). The expansion connection asmbly compris a driving core piece, and an expansion sleeve (9) consisting of expansion pieces (8). A tapered surface (31) for expansion or a curved surface for expansion is provided on each expansion piece (8). A driving tapered surface (101) or a driving curved surface is provided on the driving core piece. First holding recesd portions (4) are provided on the parent component (1). First holding protruding portions (13) matching the first holding recesd portions (4), and cond holding protruding portions (14) are provided on the expansion pieces (8). When the expansion sleeve (9) is in a fully expanded state, the first holding protruding portions (13) extend into the corresponding first holding recesd portions (4), the first holding protruding portions (13) and the first holding recesd portions (4) are mutually held to form an engagement, the cond holding
protruding portions (14) are held in the axial direction by the attachment component (2), and the expansion sleeve (9) connects and fixes the attachment component (2) together with the parent component (1). A connection will thus not fail even in adver situations such as tho having an especially large load, especially heavy vibrations, a high temperature, or alternating variations between high and low temperatures, and the connection is highly reliable.
