An elastic stress bushing comprising profiled prominences disposed at isolated locations, said profiled prominences having outer stressing surfaces, whereby the presence of the profiled prominences does not detract from the elastic properties of the overall stress bushing. This is achieved by providing for outwardly open grooves and at least one inwardly open groove on each bushing, which grooves are delimited by annular web segments and cylindrical stress covers. When the elastic bushing is compressed axially, it expands outward radially. In this way, the elastic bushing may support a workpiece, tool, hollow flywheel or sprocket, etc. from within the interior surface(s) of these structures. |
