AGGREGATE FOR COLD PRESSING BEARINGS UNITS ONTO WHEEL PAIRS OF RAILWAY ROAD CARS

摘要

FIELD: machine engineering, namely equipment for simplifying process of assembling metallic units, for example pressing sleeves or bearing races onto axle of wheel pair of railway road cars.;SUBSTANCE: aggregate has apparatus for mounting wheel pair in the form of grab type clamp having fork like levers and provided with mechanism for turning it by 180 degrees. Said mechanism is mounted on upper beams of housing. Vertically arranged shaft of said mechanism is normal relative to axis of wheel pair. Said shaft is in the form of shaft-pinion rigidly joined with housing of grab type clamp and it is mounted with possibility of engagement with toothed rack. The last is made as one piece with pistons of hydraulic cylinders of said mechanism for turning by 180 degrees.;EFFECT: enhanced operating efficiency, lowered cost price of operations.;3 dwg
