The well-known double-row self-aligning spherical roller bearing in all their design variations is characterized by common essential components, each of which has the characteristic shape of the main raceway for mating with the rolling elements. The outer ring has concave-shaped raceways, the inner ring has two concave-radial raceways and the rolling elements have curvilinear generators. The well-known two-row self-aligning spherical roller bearings can be classified into groups according to their structural features as roller bearingless and caged roller bearings. The two-row valid cageless barrel bearing consists of an outer ring, a barrel and an inner ring which may be flanged with a fixed barrel flange or without a flange, the latter having between the rows of the rolling elements guiding rings acting as a rolling flange. on the tread of the outer ring or most often on the central cylindrical part of the inner ring. Double-row self-aligning cageless spherical roller bearings are used exclusively as special bearings. A design disadvantage of the known cageless two-row self-aligning spherical roller bearings is the lack of protection of the bearing against breakage. The bearing thus constructed has no practical application, as it is not a compact body that can be easily assembled and disassembled in machines and devices, and each large mutual deflection of the rings causes the distribution of the bearing network as a whole. these disadvantages in double-row, self-aligning cageless spherical roller bearings by the use of such a structure that will prevent the bearings from crumbling during assembly by users, while not limiting its ability to self-adjust as a swinging assembly and will not reduce its load capacity. was achieved by the use of a securing ring located in the plane perpendicular to the axis of rotation of the bearing, in the central non-working part of the outer ring raceway, between the rows of barrels guided on the inner ring by at least one flange. basketless bearings the spherical roller skeleton allows the use of a self-aligning roller bearing, because only such a structure is compact and can be easily assembled and disassembled in machines and devices. The use of a securing ring in the non-working part of the outer raceway ring makes it impossible during these operations. 3 misalignment of the rings, which would cause the bearing to disintegrate and be reassembled by the user. This prevents the possibility of damage to the elements and their mixing up, which, due to the precise selection of dimensions, is a decisive factor for the qualities of the bearing in terms of its usefulness, rotation accuracy, bearing capacity and durability. The subject of the invention is shown in an example of implementation in the drawing in which fig. 1 shows a longitudinal cross-section of a two-row cageless barrel bearing, FIG. 2 shows a part of the bearing according to FIG. 1 in a front view, FIG. 3 - a side view of a securing ring, Fig. 4 - a cross-section of a plane securing ring. AA according to Fig. 3 The cageless barrel bearing according to the invention is shown in Figs. 1 and 2. This bearing consists of an outer ring 1, on the treadmill of which, in its central part, there is a circumferential groove 2, with a securing ring 3, located in the groove 2, from the known inner ring 4-and from the known barrels 5. Securing ring 3 made of wire the spring has an outer diameter greater than the diameter of the spherical race of the outer ring 1. In order to facilitate the dismounting of the bearing, ring 3 has sloping sides 6 and 7 (Fig. 3 and 4). The securing ring 3 placed in the groove 2 prevents such an angle of mutual deflection of the rings at which the barrels lose contact with the outer ring raceway, which prevents the bearing from falling apart.
