    摘要： A rolling bearing of the present invention includes an outer spacer arranged adjacent to an outer ring. On the outer spacer, a guide surface opposing a guided surface of a cage is formed such that the guide surface can slidably contact the guided surface. On the guided surface, an annular groove is provided. In the outer spacer, a flow path for oil air is provided. A discharge opening of the flow path in the guide surface opposes the annular groove within an opening width of the annular groove in the radial direction. The annular groove includes a pair of side wall surfaces inclined in opposite directions to each other so that a distance between the side wall surfaces is gradually decreased from an opening side toward a groove bottom side. The annular groove is formed such that the distance between the pair of opposing side wall surfaces is larger than a diameter of the discharge opening at a part closest to the opening side and is smaller than the diameter of the discharge opening at a part closest to the groove bottom side.

    摘要： A circumferential lubricant scoop (200) for providing lubricant to a bearing assembly. The scoop (200) is disposed circumferentially about and rotates with a rotor shaft (214). The scoop (200) comprises a plurality of lubricant capturing vanes (202) shaped to capture and retain lubricant supplied by a stationary oil jet (122) in a cavity behind a lower lip (212) of the vane (202). This cavity is in fluid communication with channels (208, 216, 218, 224, 226) leading to fluid pathways (108, 116, 118) of an inner race (106) of the bearing assembly. Fluid is moved through the channels (208, 216, 218, 224, 226) and fluid pathways (108, 116, 118) due to the rotational force imparted by the rotating rotor shaft (214).

    摘要： The invention relates to a bearing arrangement (1) for a drilling head, through which flushing liquid flows, of a deep drilling device, having multiple radially outer and radially inner bearing rings (6, 7), wherein the radially outer bearing rings (6) are arranged coaxially over the radially inner bearing rings (7), wherein, radially between the bearing rings (6), there are arranged balls (8, 9) which roll in raceways (6a, 7a) of the bearing rings (6, 7), and wherein the raceways (6a, 7a) are delimited axially on both sides by shoulders (6b, 7b) with mutually opposite shoulder surfaces (6c, 7c) which run parallel to a bearing longitudinal axis (11). In order for a bearing arrangement (1) of said type, which, as per the prior art, is adjoined in an axial direction by at least one plain bearing, to be designed to be of short axial extent and in order to simplify the construction, the internal diameter (Di) of the shoulder surfaces (6c, 7c) of the radially outer bearing rings (6) and the external diameter (Da) of the shoulder surfaces (7c) of the radially inner bearing rings (7) are dimensioned such that said shoulder surfaces (6c, 7c) perform the function of parallel radial plain bearings with a radial clearance (S).
