ROLLING BEARING Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: sealing washer are mounted on both sides of rolling bodies and positioned on the inner race at its end faces and L-shaped protecting washers from the outer side of the sealing washers. One of the sealing washers has an opening. The vertical part of one of the L-shaped protecting washers is provided with a projection. The top of the projection points to the washer that faces its and positioned in the opening in the sealing washer. Each L-shaped protecting washer has two diametrically opposite hollows arranged at a distance from the axis of the rolling bearing and mounted with two guaranteed spaced relations with respect to the surfaces of the inner race and for abutting sealing washer to permit mutual movement in the tangent direction. Each L-shaped protecting washer is provided with one arrester of its axial movement arranged on its shelf. The arrester encloses the sealing washer from the side of the inner race of the bearing. The surfaces of the sealing washer and L-shaped protecting washer fully overlap the spaces of the hollows on the L-shaped protecting washer and opening in the sealing washer. EFFECT: enhanced reliability and longevity. 2 dwg
