    • A process for manufacturing a bearing. The bearing may be used in a tool disposed within a bore hole. The process comprises providing a tubular sleeve and applying a hard facing material on the outer diameter of the tubular sleeve so that the hard facing material is fused onto the outer diameter, and thereafter applying a material layer on the outer diameter so that the material layer is fused onto the outer diameter. The method further includes machining the outer diameter so that a portion of the material layer is removed, and then machining the inner diameter so that only the hard facing material is left as an inner diameter. The method further includes machining the outer diameter and the inner diameter in order to form the bearing. In the most preferred embodiment, the method further includes placing the bearing into a housing, and inserting a mandrel into the bearing, and wherein a hard coating of the mandrel abuts the bearing. A mud motor for rotating a bit in a well bore is also disclosed.
    • 一种制造轴承的工艺。 轴承可以用在布置在钻孔内的工具中。 该方法包括提供管状套筒并在管状套筒的外径上施加硬面材料,使得硬面层材料熔合到外径上,然后在外径上施加材料层,使得材料层为 融合到外径上。 该方法进一步包括加工外径,使得材料层的一部分被去除,然后加工内径,使得仅硬面材料留下作为内径。 该方法还包括加工外径和内径以形成轴承。 在最优选的实施例中,该方法还包括将轴承放置在壳体中,并且将心轴插入轴承中,并且其中心轴的硬涂层邻接轴承。 还公开了用于在钻井中旋转钻头的泥浆马达。
