    • A well drilling head comprises a housing and a bearing assembly. The housing has a sidewall structure defining a central bore. The bearing assembly includes an outer barrel, an inner barrel, bearing units and a preload force exerting member. The outer barrel has a central bore and the inner barrel is removably seated within the housing central bore. The bearing units are coupled between the barrels for providing concentric alignment of the barrels and allowing rotation therebetween. A first one of the bearing units is configured for carrying loads exerted radially between the barrels and a second one of the bearing units is configured for carrying loads exerted longitudinally between the barrels. The preload force exerting member maintains force on the longitudinal load carrying bearing unit and said barrels thereby preloading the longitudinal load carrying bearing unit.
    • 钻井头包括壳体和轴承组件。 壳体具有限定中心孔的侧壁结构。 轴承组件包括外筒,内筒,轴承单元和预加载力施加构件。 外筒具有中心孔,并且内筒可移除地安置在壳体中心孔内。 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。 轴承单元中的第一个构造成用于承载径向施加在所述滚筒之间的载荷,并且所述轴承单元中的第二轴承单元构造为承载纵向施加在所述滚筒之间的载荷。 预紧力施加构件在纵向负载承载单元和所述套筒上保持力,由此预先加载纵向负载承载单元。

    • A well drilling head comprises a housing and a bearing assembly. The housing has a sidewall structure defining a central bore. A tapered bearing assembly seating surface is provided within the central bore of the housing. The bearing assembly includes an outer barrel having a central bore, an inner barrel at least partially disposed within the central bore of the outer barrel and bearing units coupled between the barrels for providing concentric alignment of the barrels and allowing rotation therebetween. The outer barrel is removably seated within the central bore of the housing. A tapered exterior surface of the outer barrel is engaged with the tapered bearing assembly seating surface of the housing whereby engagement of the tapered surfaces align the outer barrel with respect to the central bore of the housing.
    • 钻井头包括壳体和轴承组件。 壳体具有限定中心孔的侧壁结构。 在壳体的中心孔内设置锥形轴承组件座面。 所述轴承组件包括具有中心孔的外筒,至少部分地设置在所述外筒的中心孔内的内筒和联接在所述筒之间的轴承单元,用于提供所述筒的同心对准并允许所述滚筒之间的旋转。 外筒可移除地位于壳体的中心孔内。 外筒的锥形外表面与壳体的锥形轴承组件就座表面接合,从而锥形表面的接合使外筒相对于壳体的中心孔对准。

    • A well drilling head housing comprises a sidewall structure, a ram and selective displacement means. The sidewall structure defines a central bore configured for having a bearing assembly removably seated therein. The ram is slideably mounted on the side wall structure and is disposed within a passage extending through the sidewall structure. The selective displacement means is coupled between the ram and the sidewall structure. The selective displacement means is configured for moving the ram to an engaged position in which the ram is engaged with the bearing assembly for securing the bearing assembly in a seated position within the central bore and a disengaged position in which the ram is disengaged from the bearing assembly thereby allowing the bearing assembly to be removed from within the central bore.
    • 钻井头壳体包括侧壁结构,柱塞和选择性移位装置。 侧壁结构限定了中心孔,该中心孔被构造成具有可移除地安置在其中的轴承组件。 压头可滑动地安装在侧壁结构上并且设置在延伸穿过侧壁结构的通道内。 选择性位移装置联接在压头和侧壁结构之间。 选择性移动装置构造成用于将冲头移动到接合位置,在该位置中,冲头与轴承组件接合,用于将轴承组件固定在中心孔内的就座位置和脱离位置,在该位置中,压头与轴承脱离 从而允许轴承组件从中心孔内移除。
