A pulley, in particular a free-running pulley, comprises a pulley body having an throughgoing opening for mounting on a shaft end of a machine and provided with an inner thread cooperating with a counter-thread of the shaft end. The throughgoing opening has a portion which is arranged forwardly of the inner thread and being provided on its periphery with a contour repeating at regular distances from one another and adapted for a form-locking engagement of a tool for tightening or loosening the pulley body on the shaft.

Rectifier device for three-phase generators in vehicles

Rectifier arrangement

A three-phase current alternator is particularly suited for automotive vehicles having three-phase current coils and three diode pairs for the alternator load current. The diodes of each pair are connected with one another and with one each of the three-phase current coils by conductive tracks located in, or over, a connection plate. An interference-reducing capacitor which, together with connection tabs, forms a prefabricated unit, is molded into the connection plate, the tabs positioning the capacitor in the production mold.

Alternator with an interference-reducing capacitor

Bus strips of steel or brass, rivetted where necessary to the brush holder and to a flat plate member integral therewith serve to connect the terminals of the voltage regulator mounted on the flat plate to the brush holder and to terminals for positive and negative voltage, the exicitor winding of a generator and the D+ and D- terminals. The bus strips are soldered or welded to the terminals they connect so as to provide reliable connections for the life of the device. The negative terminal connection includes a bushing in a mounting eye of the flat plate and the positive terminal is provided as a pressure contact.
