ANTIFRICTION RADIAL ROLLER GAGELESS BEARING Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: bearing may be used in bearing assemblies characterized by higher requirements for its lifting capacity. Enhanced lifting capacity is obtained due to increasing the number of rollers in absence of cage. Function of cage in bearing is carried out by straight involute toothed wheels positioned in plane of race beads. Inner and outer races of bearing consist of rings themselves 1, 2 and pairs of gears 5, 6 and 7, 8 jointed to them by means of pins 4. Rollers include rollers themselves 3 and pair of gears 9, 10 which are set with interference fit on slotted tailpieces of rollers 3 with subsequent center-punching. Gears 5, 6, 7, 8 may be cut directly on bearing race beads, and gears 9, 10 on end sections of rollers specially extended for the purpose. In this case number of rollers in bearing is reduced. EFFECT: enhanced reliability. 6 cl, 6 dwg
