Shaft with tensioning device

摘要

The shaft has a hub pushed onto it, with a tensioning device of elastic material in which there are apertures linking recesses with the surface of the tensioning device. Tensioning screws deform the tensioning device, creating a radial pressing force. The tensioning device is a bush or a component part of the shaft or hub. The hub recesses (10, 11) run in the azimuth direction from the inside or from the endface. The recesses (e.g. 5) define projections (e.g. 6, 7) running round the hub in azimuth direction.
