RING MIT SCHICHT AUS REIBWERKSTOFF AUF KEGELFLAECHE

摘要

A ring (1) with a layer (6) of friction material on its tapered surface (2) with axial grooves (3) and teeth (5). The ratio of the groove width (N) to the tooth width (S) is between 0.5 and 3.0. The ratio of the groove depth (T) to the tooth depth is between 0.2 and 1.5. The ratio of the tooth width (S) to the periphery (U) of the friction surface (2) is a maximum of 0.001. The groove width (N) is at least 0.8 mm. The tooth width (S) is between 0.5 and 3.0 mm. The thickness (H) of a layer (6) of molybdenum is between 0.006 and 0.10 mm. The thickness (H) of a layer (6) of nickel is between 0.02 and 0.03 mm.
