SET OF COMPOSITE METAL-CERAMIC PARTS FOR INSTALLATION IN SWITCH ELECTRIC DRIVE OF CP TYPE Russian patent published in 2019 - IPC B61L5/06 

FIELD: physics.

SUBSTANCE: invention relates to switchgear electric drives of railway automation and telemechanics. Set of composite metal-ceramic parts for installation in switch-type electric drive of SP type includes disks of reduction gear box with inserts made of wear-proof self-lubricating friction material, bushing of reduction gear wheel, reduction bearings of reduction gearbox, blades of knife and switching levers of main shaft unit made of wear-resistant composite antifriction material, automatic switch knives made from composite material of increased arc resistance. Set additionally contains guide vanes and control lines, a cam insert.

EFFECT: result is period of resistance of parts installed in switch electric drive, made from composite materials, not less than 1,5 × 10⁶ actuation cycles, simplified maintenance of electric drives.
