摘要： A rotary impact tool having a twin hammer mechanism that generally includes a housing having a hollow cage or carrier member positioned therein. A pair of hollow hammer members are pivotally positioned relative to the hollow cage or carrier member so the hollow hammer members rotate with the hollow cage or carrier member under drive from an air motor output shaft. An anvil is positioned inside the hollow hammer members and the anvil rotates relative to the hollow hammer members. The anvil preferably includes a forward anvil lug, a rearward anvil lug and an annular ring positioned intermediate the forward anvil lug, and the rearward anvil lug. To facilitate assembly of the anvil through the hollow hammer members, the annular ring could be a reduced diameter annular ring or the sides of a full diameter annular ring could be reduced or narrowed. Positive spacing of the hollow hammer members can be achieved by placing a spacer between the hollow hammer members. Alternatively, positive spacing of the hollow hammer members can be achieved by extending the hollow hammer members over the annular ring on the anvil with a step provided on the hollow hammer members to provide clearance for the annular ring on the anvil.
摘要翻译： 一种具有双锤机构的旋转冲击工具，其通常包括具有定位在其中的中空笼或承载构件的壳体。 一对空心锤构件相对于中空笼或承载构件枢转地定位，使得空心锤构件随空心笼或承载构件在空气马达输出轴的驱动下旋转。 砧座位于中空锤构件内部并且砧座相对于中空锤构件旋转。 砧座优选地包括前砧座，后砧座和位于前砧座之间的环形圈和后砧座。 为了方便砧座通过中空锤构件的组装，环形环可以是直径减小的环形圈，或者可以减小或缩小全直径环形圈的侧面。 中空锤构件的正间隔可以通过在中空锤构件之间放置间隔件来实现。 或者，中空锤构件的正间距可以通过将中空锤构件在砧座上的环形环上延伸而设置在中空锤构件上的台阶上来实现，以为砧座上的环形环提供间隙。

摘要： A device containing fragments of a failed high torque device such as hydraulic torque device, geared air driven torque machine or impact wrench. The device is a sleeve formed of a woven or web-like material that is positioned around at least a driving or socket end of the high torque device. The sleeve absorbs the impact of fragments upon failure of the high torque device, preventing the fragments from becoming airborne. The sleeve may be assembled with the high torque device during construction of the high torque device, or may be added to the high torque device at a later time. The sleeve may be retro-fit onto the high torque device. The sleeve may be pre-molded, shrink-fit, hot-dipped, slid, rolled or woven onto the high torque device.

摘要： A pneumatic motor having a motor chamber having an inner surface with an eccentric longitudinal axis, a motive gas fluid inlet, and at least one end wall located transversely to the longitudinal axis with an exhaust aperture located therethrough. A rotor is rotatably disposed in the motor chamber on the eccentric longitudinal axis and having a plurality of radial slots, the rotor defining a first rotational position with respect to the longitudinal axis at which the distance between the rotor and the motor chamber is a minimum. A plurality of vanes is slidably carried within the plurality of radial slots and rotationally moving between the fluid inlet and the exhaust aperture during rotation of the rotor. The exhaust aperture is located at a second rotational position with respect to the longitudinal axis such that during rotation of the rotor, the angular distance traveled by each of the plurality of vanes between the first rotational position and the second rotational position in a first rotational direction is greater than 180 degrees.
