    • A compressor impeller for use with a boreless turbocharger is provided in accordance with this invention. The compressor impeller comprises an integral hub projecting axially therefrom that includes a partial bore therein that extends from an open to a close bore end. The bore includes a threaded portion that is configured to accommodate threaded engagement with an end of a common shaft disposed through a turbocharger housing and attached at an opposite end to a turbine wheel. The hub is specially configured so that the threaded portion has a relatively increased wall thickness when compared to a remaining portion of the bore disposed between the threaded portion and the end of the bore. The bore is configured providing a section having a reduced wall thickness, between the threaded portion and the bore closed end, for purposes of providing a preferential stress relief mechanism. Configured in this manner, the compressor impeller operates to ensure that, in the event of a stress-related compressor impeller failure, the shaft will be contained in its proper placement within the turbocharger.
    • 根据本发明提供了一种与无孔涡轮增压器一起使用的压缩机叶轮。 压缩机叶轮包括从其轴向突出的整体式轮毂,其包括其中从一开放到一孔径端延伸的部分孔。 所述孔包括螺纹部分,所述螺纹部分被配置为容纳与通过涡轮增压器壳体设置的公共轴的端部的螺纹接合,并且在相对端附接到涡轮机叶轮。 轮毂是特别构造的,使得与设置在螺纹部分和孔的端部之间的孔的剩余部分相比,螺纹部分具有相对增加的壁厚。 为了提供优先的应力消除机构,孔被配置成在螺纹部分和孔封闭端之间提供具有减小的壁厚的部分。 以这种方式配置,压缩机叶轮操作以确保在压力相关的压缩机叶轮故障的情况下,轴将被包含在其在涡轮增压器内的适当位置。

    • A hydraulic winch which is capable of generating significant amounts of torque and providing very high line pull even after a significant amount of cable is wrapped onto its spool. The winch spool is also capable of carrying a large amount of thick cable. It is useful in applications such as assisting maintenance of dredge disposal areas in which a ditching machine must be assisted by a tether across the pit of the disposal area. In the described embodiment, the novel winch includes a transportable base or skid which is affixable to a prime mover vehicle, a heavy duty spool, a chain drive and a power train. The power train for the winch is powered by a hydraulic motor. Through significant gear reduction via the chain drive and a hydraulic gear box, the winch is capable of generating sustained significant torque regardless of the amount of cable on the spool. A selectively engageable clog or dog assembly permits the spool to be unengaged so that "free spooling" can occur to permit the cable to be unrolled freely despite operation of the hydraulic motor. Additionally, the winch includes a manual brake assembly which selectively stops the spool from unrolling the cable. The winch also includes a backlash preventor in which a Teflon.RTM. drag member is maintained in frictional engagement against portions of the spool to govern the speed at which the spool will rotate.
    • 液压绞盘能够产生大量的扭矩,并且即使在将大量电缆缠绕到其卷轴上之后也能提供非常高的线拉力。 绞车卷轴还能承载大量粗电缆。 在诸如帮助维护疏浚处理区域的应用中是有用的,其中挖沟机必须通过处理区域的坑的系绳来辅助。 在所描述的实施例中,新型绞盘包括可移动的基座或滑行件,其可固定到原动机,重型卷轴,链传动和动力传动系。 绞车的动力传动系由液压马达驱动。 通过链传动和液压齿轮箱的大幅齿轮减速,无论卷轴上的电缆数量如何,绞盘都能产生持续的显着转矩。 可选择性地接合的堵塞或组件允许卷轴未被接合,使得可以发生“自由卷绕”,以允许电缆自由地展开,尽管操作液压马达。 此外,绞盘包括手动制动组件,其选择性地阻止线轴展开电缆。 该绞盘还包括一个齿隙防止器,其中特氟隆TM牵引构件与阀芯的部分保持摩擦接合,以控制阀芯将旋转的速度。
