Abstract

A fixing member in the form of a clamping disc having a radial opening, and being adapted to be clamped onto a shaft with the aid of a counter member having a coaxial opening is disclosed. Fastening means connect the disc and the counter member to one another so as to embrace the shaft when the shaft is passed through the openings. The clamping disc has a truncated and normally generally conical portion converging in a direction towards the opening, an outer rim, and an inner accordian-like annular portion integral with the outer portion. The inner portion has an inner rim and radially outwardly extending folds defining substantially flat portions between adjoining folds. The inner rim has a wave-shaped contour as viewed radially outwards. The disc is adapted to support the counter member near the outer rim thereof in an axial direction. When the counter member and the disc are tightened to one another by the fastening means, the disc is at least partially flattened and distorted so as to frictionally engage the shaft.

Dependent claims

A fixing member having an axial opening and being adapted to be clamped onto a shaft-like element passing through said opening by deforming said fixing member upon application of axially acting clamping means, comprising

an outer truncated and normally generally conical portion converging in a direction towards said opening, said outer truncated portion including an outer rim having a surface adapted to contact and axially to be supported by a counter member,
an inner accordion-like portion integral with said outer portion, said inner portion terminating in an inner rim at said axial opening,
said inner portion including radially outward extending folds, and substantially flat portions between said folds, at least some of said flat portions being adapted to be influenced by said clamping means for being axially urged in the direction of said counter member,
said inner rim having a wave-shaped countour as viewed radially outwardly and being adapted to receive said shaft-like element,
whereby upon appliction of axial pressure to said fixing member by means of said clamping means, said fixing means is in some degree flattened and said folds in some degree compressed and thereby said fixing member deformed so that said inner rim frictionally engages said shaft-like element.
