  • Pulley for an elevator with a friction reducing coating and method for manufacturing same
    Patent number: 11174130
    Abstract: A pulley for an elevator includes a base body made e.g. from steel and having a rotation-symmetrical circumferential surface. Additionally, a friction reducing coating is applied to the circumferential surface of the base body. Due to the friction reducing coating and, optionally, due to additionally smoothing the base body's circumferential surface before depositing the coating, a very low friction between an outside surface of the pulley and a contacting surface of a suspension traction member may be obtained. Thereby, guiding characteristics of the pulley may be improved and/or alignment requirements upon installation of the pulley may be relaxed. Preferably, the coating may comprise diamond-like carbon (DLC) or chromium nitride (CrN) such that the coating provides for superior wear resistance, slickness, corrosion protection and electrical characteristics.
