    摘要： A rotating inner member is used to drive a downhole tool housed within the hollow outer member of a dual-member drill string. The downhole tool preferably will be adapted to receive rotational energy from the inner member. In a preferred embodiment, the downhole tool is an electric generator connected to a downhole electric device. In another preferred embodiment the downhole tool is a mechanical transmission that uses the rotational energy from the inner member to drive a non-electric tool, such as a downhole hammer. This invention will increase the consistency and efficiency of downhole energy production.

    摘要： A downhole tool for generating a longitudinal mechanical load. In one embodiment, a downhole hammer is disclosed which is activated by applying a load on the hammer and supplying pressurizing fluid to the hammer. The hammer includes a shuttle valve and piston that are moveable between first and further position, seal faces of the shuttle valve and piston being released when the valve and the piston are in their respective further positions, to allow fluid flow through the tool. When the seal is releasing, the piston impacts a remainder of the tool to generate mechanical load. The mechanical load is cyclical by repeated movements of the shuttle valve and piston.

    摘要： A fluid-activated, percussive impact tool has a piston therein that reciprocates longitudinally but not rotationally. The piston activates a wrap spring clutch to rotate the drill steel. A removable splined nut in combination with the tool's housing restrains rotation of the piston, while permitting longitudinal reciprocation of the piston.

    摘要： A clutch assembly transmits rotary motion in a percussive apparatus to a drill steel. The clutch assembly includes a first hub having a first cylindrical surface formed thereon. A second hub which is substantially rotationally coupled to the drill steel has a second cylindrical surface formed thereon. The second cylindrical surface is coaxial with the first cylindrical surface. A wrap spring engages a portion of both the first cylindrical surface and the second cylindrical surface, wherein relative rotary motion between the first hub and the second hub is permitted in a first direction and restricted in a second direction. The wrap spring clutch transmits motion supplied from a rifle bar assembly as well as a plunger bar arrangement.

    摘要： The invention is a rotary drive system for a jack hammer which incorporates a plurality of annular sleeves to transfer the motion generated by the piston to the tool holder and thereby allows the piston to strike the tool when the piston moves in the forward direction. Upon the return stroke of the piston, the annular sleeves are provided with mutually engaging helical splined teeth which causes a partial rotation of the tool holder and thereby provides rotation of the tool holder prior to the piston's next impact with the tool. All of the components are annular and, therefore, easily assembled into the bore of the jack hammer housing. Also, the use of helical splines significantly reduces the frictional resistance of the complete system.

    摘要翻译： 本发明是一种用于千斤顶锤的旋转驱动系统，其包括多个环形套筒，以将活塞产生的运动传递到工具夹具，从而当活塞沿向前方向移动时允许活塞撞击工具。 在活塞的返回行程时，环形套筒设置有相互接合的螺旋花键齿，其引起工具保持器的部分旋转，从而在活塞与工具的下一次冲击之前提供工具夹具的旋转。 所有部件都是环形的，因此易于组装到千斤顶锤壳体的孔中。 此外，螺旋花键的使用显着降低了整个系统的摩擦阻力。
