Articles including at least two members joined together

摘要

An article has a first member (10) with a cylindrical end portion (15) in which there is at least one circumferentially extending groove (17) and a second member (18) to which an annular collar (20) is secured. The first and second members are secured together by an annular layer (19) of material, preferably elastomeric, pressed between the cylindrical end portion (15) and the annular collar (20) such that the material is forced into the groove (17). A typical article is a propeller blade attached to a base plate.
