Two=part spacer fabricated from permanently magnetised materials

摘要

Two components (1,2) separated by a spacer (3,4) are held together by a nut (6) and bolt (5) passing through the components (1,2,3,4). Each part of the two-part spacer has a helical interface with mirror-image opposed drive-interfaces (7,14). The two-part spacer is made of a magnetised permanently magnetic material. The spacer element may have a rear side (3') with one or more pin elements eccentrically arranged as extensions. The supporting surfaces (7,8) may have corrugations (15) on it.
