Abstract
A roller for belt tensioning systems or wrap drives having a hollow hub and a cylindrical running ring. The hollow hub and the running ring are connected to one another by an annular web and wherein, on both sides of the annular web, the hollow hub and the running ring are supported relative to one another by circumferentially distributed radially arranged ribs. The number of ribs on both sides of the annular web can be a prime number. In addition, or in the alternative, the ribs on both sides of the annular web can be arranged so as to be non-centrically circumferentially offset. In addition, or in the alternative, the number of ribs on both sides of the annular web can deviate from one another. In addition, or in the alternative, the rib assembly can be provided with variable pitch angles around the circumference.
