    The invention relates to mechanical engineering, in particular to bearings for high speeds.
    A bearing for high rotation speeds is known, comprising an inner rotating and fixed outer race with rolling elements in the cage between them, ring plates, covers at its ends and porous rings impregnated with grease, placed between the covers and ring plates £ 1J .
    A disadvantage of the known bearing is its low durability, 15 since the porous ring is in direct contact with a high-speed bearing race.
    The purpose of the invention is to increase the durability of the bearing. 2 o
    This goal is achieved by the fact that, in the bearing for high speeds of rotation, containing internal rotating and external stationary cages with rolling bodies · in sep, 2 ratios between them, ring plates, covers on its ends and porous 1 rings, impregnated with grease, placed between the covers and the annular plates, each porous ring is made with an annular pointed protrusion directed to the side of the rolling elements and located with a gap relative to the inner rotating cage.
    An annular recess is made on the outer surface of the porous ring from the end face adjacent to the outer race of the bearing, and the bearing is provided with a grease source located in the annular recess in the form of an absorbent ring impregnated with grease.
    The annular plate is placed on the inner surface of the annular protrusion with a gap relative to the outer race of the bearing.
    The inner surface of the annular protrusion is covered with a sealing layer.
    The outer cylindrical and end surfaces of the porous ring are coated with a sealing layer.
    The drawing shows the proposed bearing. . S
    The bearing for high rotational speeds consists of a fixed outer race 1 and an inner race 2, rotating with the shaft. 3. Between the clips are placed bodies ·. 4 rolling elements 10 in the separator 5, and the porous rings 6 impregnated with grease adjoin the ends of the outer casing with covers 7 and ring plates 8. Each is porous. the ring, for example, of cermet material 15, is made with an annular pointed protrusion 9 located with a gap relative to the conical surface 10 of the inner cage. An annular recess 11 may be provided on the outer surface of the porous ring to accommodate a lubricant source in the form of an absorbent ring 12 made, for example, of felt. The functions of the covers 7 and the annular plates 8 can be performed by a sealing layer placed on the porous rings in place of the covers and annular plates.
    The bearing operates as follows.
    During rotation, centrifugal forces create a vacuum at the inner race of the bearing, pulling the grease from the porous ring, the grease from the pointed part of the annular protrusion enters the bodies and raceways, and then returns to the porous ring through the gap between the outer race and the ring plate, while being filtered in a porous ring, 40
    Lubricants can also be installed from only one end of the bearing, then a seal must be provided from its other merchant. 45
    The implementation of the bearing for high rotational speeds with a porous ring placed with a clearance relative to the inner race of the sleeve increases the durability of the bearing.

    The invention relates to mechanical engineering, in particular, to bearings for high rotational speeds. A bearing for high rotational speeds is known, comprising a rotating and fixed outer outer ring with rolling elements in a separator between them, annular plates, caps on its ends and porous rings impregnated with grease, once placed between caps and ring plates. one . A disadvantage of the known bearing is its low durability since the porous ring is in direct contact with the high-speed bearing race. The purpose of the invention is to increase the durability of the bearing. The goal is achieved by the fact that in a bearing for high rotational speeds, containing an inner rotating and outer fixed cage with rolling elements in sepa, 2 between them, ring plates, caps on its ends and porous rings impregnated with grease, placed between the lids and annular plates, each porous ring is provided with an annular pointed protrusion directed toward the side of the rolling bodies and located with a gap relative to the internal rotating cage. An annular recess is made on the outer surface of the porous ring from the end face adjacent to the outer bearing race, and the bearing is provided with a source of lubricant placed in the annular recess impregnated with lubricant. The annular plate is placed i on the inner surface of the annular ledge with a gap relative to outer bearing race. The inner surface of the annular protrusion is covered with a sealing layer. The outer cylindrical and end surfaces of the porous ring are covered with a sealing layer. The drawing shows the proposed bearing. . The bearing for high rotational speeds consists of a fixed outer cage 1 and an inner cage 2 rotating with the shaft. Bridges are accommodated bodies. The rolling rollers in the separator 5.3 adjoin the ends of the outer cage with lubricated porous rings 6 with covers 7 and ring plates 8. Each porous ring, for example, of a cermet material, is made with an annular pointed protrusion 9 located with a gap relative to the conical surface 10 of the inner On the outer surface of the porous ring, an annular recess 11 can be made to accommodate a source of lubricant in the form of an absorbent ring 12 made, for example, of felt. The functions of the covers 7 and ring plates 8 can be performed by a sealing layer placed on porous rings in place of the covers and ring plates. The bearing works as follows. When rotating, centrifugal forces create a discharge at the inner bearing of the bearing, draw grease from the porous ring, grease from the pointed part of the annular protrusion gets onto the bodies and the raceways, and then returns to the porous ring through the gap between the outer cage and the annular plate, while filtering sit in a porous ring. Lubricants can also be installed only from one end of the bearing, then from the other of its trade it is necessary to provide a seal; Making the bearing for high rotational speeds placed with a gap relative to the internal rotation (a porous ring cage increases the durability of the bearing. Claim 1. Bearing for high rotation speeds containing an internal rotating and fixed outer cage, with rolling elements in the separator between them, annular plates, lids on its ends and porous rings impregnated with a lubricant placed between the lids and annular plates, characterized in that, in order to increase the long echnosti bearing operation, each porous ring is formed with an annular tapered projection directed towards the rolling bodies and disposed with a gap relative to the inner rotary cage.

    3. Bearing in PP, 1 and 2, characterized in that the annular plate is placed on the inner surface of the annular protrusion with a gap relative to the outer race of the bearing. j. A bearing according to claim 1, characterized in that the inner surface of the annular protrusion is covered with a sealing layer. 5. Bearing in ppt 1 and 2, which is similar to the fact that the outer cylindrical and end surfaces of the porous ring are covered with a sealing layer.
