    • In a rotor bearing housing comprised of split half sections (10) and adapted to be joined at horizontal joining surfaces (12) of the half sections, and wherein each half section includes a beating recess flanked on either side thereof by a seal recess (16, 18); and a pair of annular bearing seals (24), each comprising a pair of half segments (26, 28), each segment adapted to be received in a respective seal recess in a split half sections of the housing, each segment having a pair of substantially horizontal interface surfaces (30, 32) at diametrically opposite sides thereof, the improvement comprising a groove (46) formed in each interface surface (30, 32), extending across a radial thickness dimension of the segment, such that opposing grooves in opposing interface surfaces combine to form a pair of oil channels in each annular bearing seal.
    • 一种转子轴承壳体,包括分开的半部分(10)并且适于在半部分的水平接合表面(12)处接合,并且其中每个半部分包括通过密封凹部(16)在其两侧侧面的打浆凹槽 ,18); 以及一对环形轴承密封件(24),每个环形轴承密封件(24)包括一对半部分(26,28),每个部分适于容纳在壳体的分开的半部分中的相应的密封凹部中,每个部分具有一对 基本水平的接口表面(30,32)在其直径相对的两侧,其改进包括形成在每个界面(30,32)中的槽(46),其延伸穿过该段的径向厚度尺寸,使得相对的槽 接口表面组合在每个环形轴承密封件中形成一对油通道。
