FORBINDELSESELEMENT TIL OVERFORING AF ET DREJNINGSMOMENT

摘要

A tubular spacer ring for frictionally fastening a shaft in the oversized bore of a machine element is bent from a strip of embossed sheet metal having several circumferential rows of axially elongated projections on one face and corresponding recesses in the other face. The projections have a preferred axial length of 5-8 times their radial height, and must have a length of 3-10 times the height. The projections are identical and uniformly distributed in each row, but the rows are circumferentially offset by a fraction of the center-to-center spacing of the projections in each row.
