摘要

Wedge ribs disk for a wedge ribs belt drive, wherein the wedge ribs disk (10) on a basic body (14) are spaced apart from one another which are arranged largely wedge-shaped first ribs (11) has, in the first intermediate space (13) second spaced ribs (3) of a wedge-ribbed belt (2) engage, and between the second ribs (3) a second intermediate space (12) is formed, into which the first ribs (11) engage in such a manner that in the first intermediate space (13) between a base (15) of the first ribs (11) and a rib head (16) of the second ribs (3) remains a free space, characterized in that a ratio of the a longitudinal center axis of the disks base body which encloses the cross-sectional areas of the free spacer surface (a1) of the first intermediate space (13) between the base (15) and the rib head (16) and the of the second ribs (3) enclosed surface (v) of the second intermediate space (12) is at least 0.5.
