ROLLER BEARING Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has rollers, which are made in two-step form. Diameter of greater roller step is run in only along rolling track of outer bearing racer. Diameters of lesser step are run in only along rolling tracks of inner racer with equal constant rotation speed. Assemblage condition should apply to the bearing, said condition being: d1m/Dwm1=D1m/Dwm2, where: d1m - rolling track diameter for inner racer; Dwm1 - lesser roller step diameter; D1m - rolling tracks diameter of outer racer; Dwm2 - greater roller step diameter. Rolling track of inner racer is made with through recesses for forming a gap with greater diameter of roller steps. Such construction allows rollers to roll along bearing roller tracks without slippage. EFFECT: assured proper rolling of rollers during their running in rolling tracks, increased limiting rotation frequency, lowered noise during operation. 2 dwg
