The rope pulley has a rolling bearing between its inner hub enclosing a concentric ring. The contacting circumferential faces of the hub (2) and the inner ring (4, 5) have grooves (3, 7). Into each groove are placed two race wires (8, 9) of semicircular cross section. Cylindrical rolling elements (10) roll on these wires. The axes of these cylindrical rollers are placed alternately at right angles to each other. The inner ring in the region of the groove (7) is split in the plane normal to the axis. Both ring halves (4, 5) are connected by bolts (6) arranged on the circumference. |
