Abstract: Illustrative embodiments of impact tools with speed controllers and methods of controlling such impact tools are disclosed. In at least one illustrative embodiment, an impact tool may comprise a ball-and-cam impact mechanism including a hammer and an anvil. The hammer may be configured to rotate about a first axis and to translate along the first axis to impact the anvil to cause rotation of the anvil about the first axis. The impact tool may further comprise a motor and a speed controller. The motor may include a rotor configured to rotate when a flow of compressed fluid is supplied to the rotor to drive rotation of the hammer of the ball-and-cam impact mechanism. The speed controller may be coupled to the rotor and may be configured to throttle the flow of compressed fluid supplied to the rotor based on a rotational speed of the rotor.

Abstract: The pneumatic hammer includes a hollow housing with handles for the user. A pneumatic driver is mounted inside the housing with an air tank for pressurized air. A reciprocating hammer assembly is slidably mounted inside the pneumatic driver and includes a hammer with a sharp hammer tip. The hammer is substantially hollow to efficiently capture released air from the air tank and drive the same. An alignment collar extends out of the housing and couples to the hammer assembly to set alignment of the hammer against an object to be impacted. The collar is normally locked in place. A control assembly is coupled to the housing, the pneumatic driver, and the collar to selectively release air driving the hammer out of the housing and unlock the collar for slidable movement into the housing.

Abstract: The optimized pneumatic hammer is characterized by maximum performance efficiency that is achieved due to author's analytical investigations which revealed the existence of the optimal value of the striker's length with respect to maximum kinetic energy of the tool. On the contrary to the existing hammers, in the optimized hammers the length of the strikers is shorter than their strokes. Calculations based on the mentioned investigation show that the kinetic energy of optimized hammers could be about 2.5 times higher than of their existing counterparts. The optimized pneumatic hammer has two modes of operation—the regular mode of operation during which the tool interacts with the target media and the retracting mode of operation for releasing the severely jammed tool from the media. Optimized pneumatic hammers allow for a considerable decrease of their weight and diameters without compromising their performance while making easier the work of the operators.

Abstract translation: 优化的气锤的特点是最大的性能效率是由于作者的分析研究而实现的，这显示了相对于工具的最大动能的撞击器长度的最佳值的存在。 与现有的锤子相反，在优化的锤子中，罢工者的长度比他们的中风短。 基于上述调查的计算表明，优化锤的动能可能比现有的锤子高出约2.5倍。 优化的气锤具有两种操作模式 - 工具与目标介质相互作用的常规操作模式以及用于将严重卡住的工具从介质释放的缩回操作模式。 优化的气锤可以显着降低其重量和直径，同时不会影响其性能，同时更容易操作操作人员的工作。

Abstract: A power tool and control method is disclosed. The power tool has a striker, which is guided along an axis parallel to an impact direction. A pneumatic chamber has a volume which varies with a movement of the striker along the axis. A valve device that is actuatable depending upon the movement direction of the striker connects the pneumatic chamber with an air reservoir. The valve device is actuated to open in the case of a movement of the striker in the impact direction and in the case of a movement of the striker against the impact direction is actuated to throttle or close. The throttled or closed valve device restricts an air flow flowing through it to a maximum of one tenth of the value as compared to the air flow in an opened position.

Abstract: An impactor for use with a directional boring machine for replacement of underground pipes includes a bursting head having a rearwardly opening recess and a front end opening that communicates with the recess. An inlet pipe is connected at its front end to a distal end of the drill string and extends into the recess of the bursting head through the front end opening. A striker is mounted for sliding movement along the inlet pipe, and a distributing mechanism responsive to pressure fluid supplied through the drill string and inlet pipe causes the striker to reciprocate in the rearwardly opening recess of the head to deliver forward impacts against the bursting head. The striker and distributing mechanism are mounted in a tubular housing, and a pulling connection is provided by which the impactor can be pulled by the drill string while the striker is delivering impacts against the head in the same direction as a pulling force exerted by the drill string. The bursting head is preferably slidably mounted on the inlet pipe and moves forward relative to the inlet pipe and drill string in response to an impact of the striker against the bursting head. The impactor can be readily used with existing directional boring machines.

Abstract: A hammer holder, provided between a retainer sleeve and a cylinder, slidably holds an intermediate member in an axial direction. A predetermined clearance is maintained between the hammer holder and the retainer sleeve. The hammer holder has a recessed portion which is engageable with a flange of the intermediate member so as to restrict the slide movement of the intermediate member. A cushioning member receives a percussion force when the flange is stopped by the recessed portion. The clearance restricts a compression amount of the cushioning member so that a predetermined life of the cushioning member is assured.
