COLLECTOR DEVICE Russian patent published in 1999 - IPC

FIELD: instrumentation. SUBSTANCE: collector device includes mobile contact plates which contact brushes. Brushes are manufactured in the form of rollers rotating around axles fixed in mobile spring-loaded rods. Rollers are installed along tangent line to radius of plates. Plates, axles and rollers are made from wear-resistant alloy, for example, German silver. Rods in section present polygon, for instance, square. Such design of collector device enables rolling friction in point of contact to be used and wear-out of parts to be reduced which enhances reliability of contact and prolongs service life of collector device. EFFECT: enhanced reliability of contact and prolonged service life of collector device. 1 cl, 2 dwg
