摘要：
A bearing assembly for a well drilling head has an outer barrel, an inner barrel, bearing units and a cover plate. The outer barrel has an upper end portion, a lower end portion and a central bore extending therebetween. The inner barrel is at least partially disposed within the central bore of the outer barrel. The bearing units are coupled between the barrels for providing concentric alignment of the barrels and allowing rotation therebetween. The cover plate is non-rotatably attached to the upper end portion of the outer barrel. An upper end portion of the inner barrel is exposed within a central opening of the cover plate. An outside edge portion of an upper surface of the cover plate encompassing the central opening is downwardly angled with respect to a central axis of the cover plate.
摘要（中）：
用于钻井头的轴承组件具有外筒，内筒，轴承单元和盖板。 外筒具有在其间延伸的上端部，下端部和中心孔。 内筒至少部分地设置在外筒的中心孔内。 轴承单元联接在桶之间，以提供筒的同心对准并允许其之间的旋转。 盖板不可旋转地附接到外筒的上端部。 内筒的上端部暴露在盖板的中心开口内。 覆盖中心开口的盖板的上表面的外边缘部分相对于盖板的中心轴线向下成角度。
