Abstract
A belt tensioner for attaching to a generator of an auxiliary unit drive of an internal combustion engine, including a tensioner housing mounted on the generator having a cavity, two tensioning rollers which act with a pretensioning force on the belt in a direction of revolution upstream and downstream of the pulley of the generator, a bow spring which produces the pretensioning force accommodated in the cavity, a circular-arc-shaped tensioning lever mounted in the cavity movable in a plane of the circular arc and which is acted on by the force of the bow springs and supports one of the tensioning rollers, and a sliding bearing for the tensioning lever, which sliding bearing extends at the inlet of the cavity. The tensioning lever has a steel core with an aluminum sheath which completely encloses the part of the steel core which extends outside the cavity and inside the sliding bearing.
