    This invention relates to hydrodynamic angular contact bearings with automatic pumping of lubricating oil. The purpose of the invention is to expand the functionality. The autodynamic hydrodynamic bearing 4 has between the two segments of the pumping unit 11. On its concave cylindrical surface facing the shaft 1 the pumping pockets in the form of flat recesses, into which, due to the hydrodynamic effect, lubricating oil is sucked through the channels of the sump the backpressure count on the transverse bridges at the end of the inflation pockets is squeezed into the circulation circuit. 2 hp f-ly, 5 ill.

    Claims (3)
    [1]
    The claims are two support points in which the support plates 34 enter into the cobble pads 36. The support rod 35 passes through the hole 37 down into the hydraulic reinforcing element 33, in the upper part of which it is screwed in. threads 39. The reinforcing element has an upper 40 and a lower 41 plate, flexibly connected to each other by means of a corrugated tube 42 and thus forming a closed chamber 5, which through the oil pressure pipe 43 is in a conductive connection with. circulation circuit of lubricating oil. . P
    The pin 44 connected to the lower plate 41, its upper end enters the sleeve 45 connected to the upper plate 40 and thereby centers both plates 40 and 41 one 45 relative to the other. The lower end of the pin 44 has a longitudinal opening into which a centering pin 46 enters, guiding the lower plate 41 and at the same time serving as a stop gg for this plate. It is screwed into the base plate 47 and secured with a nut 48. The base plate 47 is fastened with spacer bolts 49 to the carrier ring 12 and receives a coil spring 50 located between the base plate 47 and the bottom plate 41 in its center. Two round cord rings 51 on
