摘要： An impact mechanism includes a shaft, a hammer and an anvil coupled to the hammer. The shaft has a first helical groove and the hammer has a second helical groove. A ball is received in the first and second helical grooves to rotationally couple the hammer to the shaft and permit axial travel of the hammer relative to the shaft. An axial stop inhibits axial travel of the hammer along a first travel path and permits axial travel of the hammer along a second travel path. The axial stop includes first and second stop members, the first and second stop members having a first relative position to inhibit axial travel of the hammer and a second relative position to permit axial travel of the hammer.

摘要： An overload clutch assembly for a power tool having two torque settings through which rotary drive is transmitted to a spindle. The overload clutch assembly is capable of being between switched between the two torque settings by at least one actuator. The clutch assembly comprises a carrier rotationally mounted on a output clutch spindle; a first clutch plate operational for transmitting torque below a first level; and a second clutch plate operational for transmitting torque below a second level higher than the first; and characterised in that, when the overload clutch is in the higher torque setting, the torque is transferred from the carrier to the output clutch spindle via the second clutch plate only.

摘要： A miniature impact tool in which a cam and cam follower assembly is utilized for moving a striker backward by converting rotary motion of a drive shaft to a linear motion. The striker is in contact with a spring/guide pin (plunger) assembly and is moved away from a surface to be struck during a portion of the rotation cycle of the cam. On further rotation the cam surface is cut away and spring action drives the striker forward, causing impact of a cutting tool (chisel) against a workpiece. A plurality of cam lobe surfaces provides predetermined and reproducible impact forces of the cutting tool on the workpiece, even during vibration of the tool. To minimize damage to the cam and cam follower when the tool is over speeded, an elastomeric cam or a cushioning coating or sleeve prevents adverse contact (such as metal-to-metal contact) between the cam and cam follower.
摘要翻译： 一种微型冲击工具，其中通过将驱动轴的旋转运动转换为直线运动，凸轮和凸轮从动件组件用于向后移动撞针。 撞针与弹簧/导销（柱塞）组件接触，并且在凸轮的旋转周期的一部分期间被移动远离被撞击的表面。 在进一步旋转时，凸轮表面被切除并且弹簧作用将前进杆向前驱动，引起切削工具（凿子）对工件的冲击。 多个凸轮凸角表面即使在工具的振动期间也提供了切削工具在工件上的预定和可再现的冲击力。 为了最大限度地减少当工具超速时对凸轮和凸轮从动件的损坏，弹性凸轮或缓冲涂层或套筒可防止凸轮和凸轮从动件之间的不良接触（例如金属与金属的接触）。

摘要： An air cylinder apparatus for a pneumatically driven power tool includes a unitary outer cylinder member, which has a bearing plate and a hollow cylindrical wall. A cylindrical chamber is formed eccentrically in the cylindrical wall. A bearing member is mounted removably on an end of the cylindrical wall. A cylindrical inner wall member is press fitted within the cylindrical wall of the outer cylinder member, and has two spaced adjacent axial sides that define an open-ended axial slot therebetween. The inner wall member can be compressed in a radial direction for removal from the outer cylinder member. Because the outer cylinder member is molded, the power tool can be manufactured easily and conveniently.

摘要： The present invention relates an impact tool with a twin lobed anvil, and the separate anvil, timing shaft and mating dog hammer. The impact transmission is configured in such a way so as to maintain contact between the anvil and dog hammer. As a result, the components of the present invention provide a harder blow to the anvil of an impact tool due to a larger strike surface area, provide greater torque due to increased mass at engagement, and increase the durability of the impact tool.
