UNDER-RAIL LATHE FOR PROCESSING WHEEL PAIRS WITH ADJUSTABLE TRACK WIDTH Russian patent published in 2020 - IPC B23B5/32 

FIELD: transportation; technological processes.

SUBSTANCE: under-rail machine is designed for wheel pairs processing and is made with possibility of recovery of wheel wheels and braking disks of wheel pairs (20) of rail vehicles. Machine includes bed (3), transverse beam (2) for overlapping rail track (4) of workshop with at least two rails (4A, 4B, 4C) in transverse direction, two roller carriers (7A, 7B), at least four friction rollers (8), at least one drive (9) for driving friction rollers (8) and at least one axial guiding roller (19) for guiding axis of wheel pair (20). Bed (3) has first (3A) and second (3B) parts, transverse beam (2) is supported by both parts (3A, 3B) of foundation, roller carriers (7A, 7B) are movably connected to bed (3), and friction rollers (8) are installed with possibility of rotation on corresponding roller bearing device (7A, 7B). First (3A) and second (3B) parts of bed (3) are configured to move relative to each other in transverse direction to allow adjustment to wheel pairs (20) with different track width.

EFFECT: enabling expansion of technological capabilities due to machining of wheel pairs with different track width.
