摘要： A belt tensioner, comprising a first and second tensioning arm supported on a generator housing, a first and second tensioning roller attached to the first and second tensioning arms and configured to apply a pre-tensioning force to an auxiliary unit belt drive, and a bow spring clamped between the first and second tensioning arms in axial overlap with the tensioning rollers and configured to produce the pre-tensioning force.

摘要： A bearing ring comprises a raceway for a rolling member as well as at least one lateral rim for axially guiding the rolling member. To produce the bearing ring a notch is introduced into a running surface of the bearing ring which faces the rolling member. A final contour of the bearing ring is created by means of a hard turning process.
