Abstract

A tensioning mechanism for drive belts which consists of a support arm, a rotating tensioning roll mounted on the arm, and a pivot bearing on the support arm a certain distance away from the tensioning roll. The tensioning mechanism is attached together with a mounting plate by a fastener to a machine block. A spring urges the tensioning roll away from the mounting plate and toward the drive belt. In the area of the pivot bearing, the mounting plate has, in the axial direction of the bearing, a fork-shaped cross section with shank sections which support the pivot bearing on both sides, radially and axially, by way of the fastener.
