FIELD: mechanical engineering and other industries. ^ SUBSTANCE: proposed anti-friction bearing is just radial-thrust single-row bearing with inner and detachable outer races and single-stage rollers located between them and mounted in cage. Larger diameter of larger stage of roller is engageable only with two raceways of detachable outer race at two points at angle alpha. Lesser diameter of cylindrical roller stage is engageable through intermediate member only with two raceways of inner race at two points at constant and similar speed of rotation. Raceway of inner race is provided with circular bore forming clearances under larger diameter of larger stage of roller. Intermediate member is made in form of rigid torus ring exceeding lesser diameter of roller stages. Raceways for rigid torus ring are made on outer side of inner race of bearing; grooves for torus ring are made on cylindrical surfaces of lesser diameters of roller. ^ EFFECT: enhanced durability of bearing due to avoidance of slippage of rollers; reduced elastic hysteresis in zone of engagement of lesser diameter of roller stages. ^ 1 dwg |
