Title: Rope drive element for driving synthetic fiber ropes
Inventor: DE ANGELIS CLAUDIO
IPC: F16H55/38
Filed: 2000-10-26
Abstract: This rope drive element for driving synthetic fiber ropes, preferably for a rope drive (1) of an elevator installation, ensures a consistently good selected tractive capacity which is largely independent of external influences which reduce friction. According to the invention, at least part of the rope running surface (7,17,27) is given a surface (14,37) with roughness grade N7 to N12. The surface is formed either by mechanical machining or by use of a suitable coating, preferably a plasma coating of corundum. In preferred embodiments the synthetic fiber rope or ropes run in rope grooves (7,17,27) in which the surface is formed, for example, only in the bed of the rope groove (7), in the area of the flanks (17), or over a wide area of the surface of the rope groove (27). By correspondingly suitable arrangement of these differently formed rope grooves (7,17,27) on a drive element (2), a desired tractive behavior can be systematically effected.
