APPARATUS FOR PRESSING BEARINGS ONTO WHEEL PAIRS Russian patent published in 2002 - IPC

FIELD: mechanical assembling production systems. SUBSTANCE: two pedestals are mounted on foundation. Pressing-in apparatuses are mounted on said pedestals. Each pressing-in apparatus includes hydraulic cylinder with spring-loaded center; device for retaining bearing assembly and unit for moving it in the form of rod of hydraulic cylinder. Rods of hydraulic cylinders are oriented one towards another. Unit for mounting wheel pair is arranged between pedestals; said unit is in the form of rails with stopper controlled by means of pedal. Between rails there are telescopic hydraulic cylinders of lifter of wheel pair. Hydraulic cylinder of each pressing-in apparatus also is telescopic one and it has additional rod whose one end supports device for retaining bearing assembly and whose other end carries rigid stop for limiting motion of rod. Each telescopic hydraulic cylinder of lifter has inner plunger provided with piston whose surface area is less than that of piston of outer rod by 2.5 times. EFFECT: simplified design, reduced size of apparatus, enhanced efficiency of assembling process, improved quality and accuracy of assembled articles. 2 cl, 5 dwg
