Abstract
An annular clamping member adapted, for example, to clamp a gear or a pulley to a plain shaft has a ring of alternately arranged primary and secondary sections (1 and 2) mutually interconnected by means of inclined ring portions (12) which, by a forced mutual displacement of the primary and secondary sections, are caused to change their inclination whereby an increase or decrease of the diameters of the clamping member is obtained. Such a clamping member may be used for clamping a transmission element exactly coaxially to a shaft or may be formed as a hub of such a transmission element.
Claims9
An annular clamping member adapted to surround a shaft or to extend against an inner annular surface, said clamping member having a variable circumferential length;
- and constituted by a plurality of parts evenly distributed and including two opposite radial faces lying in opposite directions away from their positions when said member is at rest;
- said member comprising a ring having two oppositely facing axial ends;
- and alternately arranged, axially displaceable primary and secondary sections at said ends;
- inclined ring portions mutually interconnecting said primary and secondary sections;
- said inclined ring portions being changeable in their inclination by the forced mutual displacement of said primary and secondary sections whereby the diameter of said clamping member can be increased or decreased.
