Drive belt disc for IC engine crankshaft has disc bearing fitted in radial gap between projection of visco-oscillation damper housing and drive belt disc

摘要

The drive belt disc (1) has an integrated visco-oscillation damper (2) having an oscillation ring contained in a damper housing (5) filled with a viscous medium. The damper housing has an axial projection (8) enclosed by the drive belt running surface (9) of the drive belt disc at a relative radial spacing, providing a gap (10) for the bearing (6) for the drive belt disc.
