Alternator structure for assembly with a mobile internal combustion engine, particularly for automotive use

摘要

To permit random selected positioning of an attachment arm (32) formed on the shell of an alternator with respect to a locating arm (33) thereon to tighten a drive belt driving the alternator from the engine, the locating arm (33) is integral with an end cover shield (12) attached to the shell (11). Preferably, the shell (11) is of hexagonal cross section, the shield (12) is likewise a hexagonal cross section, with attachment screws and screw openings in the corners of the hexagon to permit selected angular positioning of the locating arm and the attachment arm with respect to each other and match the configuration of the arms to different types of engines with which the alternator is to be used.
