Abstract: The present invention deals with a new system for transmitting energy through a cable (2) and interconnected pulleys (1, 3, 5). The traditional power transmission through pulleys sizes the system of belts and friction surfaces depending on energy to be transmitted and is obtained through systems composed of a rotary element for every point of application and of a flexible element for the connection. In the proposed system, the flexible element is a high-resistance cable (2) and friction on the rotary element is increased by using interconnected pulleys, which increase the cable friction surface allowing power transmissions without any sliding till the cable breaking point. The lightness of such system allows it to find optimum application in transmitting to ground all wind energy produced at an upper level. The system of interconnected pulleys (1, 3, 5) is further applied to discontinuous tractions in the sailing field, replacing the traditionally used winches.

Abstract: A bearing housing (23) for a drive device (27) integrated in a creel (18) of a cheese-producing textile machine, which brakes the cheese (11) via a braking current directed opposite the nominal rated current of the drive device. The bearing housing (23) has a plurality of cooling ribs (33), whose exterior is covered with a material having a low heat conductivity (8).
