摘要

Viscosity - a torsional vibration damper or viscosity - the torsional vibration damper (1) for the reduction of torsional vibrations on the crankshaft (7) of a reciprocating engine, wherein for the cooling of the viscosity - torsional vibration damper or viscosity - torsional vibration damper (1) on the housing (2), which has a receiving chamber (4) for a rotating ring (5) and forms by means of a cover (3) is closed, on its outside, a surface structure (6) for enlarging the surface of the housing (2) and / or for producing a laminar and / or turbulent flow is mounted, wherein the surface structure (6) directly into the housing walls and / or the housing cover (3) is introduced and from wing-like projections (6a, 6c), characterized in that the surface structure (6) with their protuberances (6a, 6c) as a signal transmitter for a sensor (9) for determining the respective current angular position of the crankshaft (7) is designed.
