摘要： The conventional rapper design is improved to provide longer service without maintenance and easier access at less cost when service is required by, among other things, redesign of the hammer assembly, hammer shaft and lever assemblies, and the hammer assembly housings. Design improvements include the provision of access panels on the housings, a guide and lock mechanism for removing and inserting the hammer assembly out of and into the hammer assembly housing, providing the hammer with a removal, and keyed engagements of hammer shaft assembly components.

摘要： The invention relates to a pneumatic percussive mechanism for a percussion drill and/or a drill hammer. The inventive mechanism comprises, housed in the housing of the percussive mechanism, an axially reciprocating percussion piston. A drive piston is axially reciprocated in a guide cylinder of said percussion piston. The guide cylinder is provided on its inner face with one or more air compensation pockets. At least one idle opening extends through the guide cylinder. In the percussive action, the idle opening does not communicate with the ambience while in the idle mode the idle opening can be displaced via an idle channel that leads to the ambience and thus connects a cavity that receives a pneumatic piston with the ambience by way of the idle opening. The air compensation pockets and the idle openings allow and optimization of the piston return behavior and of the idle operation of the percussive mechanism.

摘要： A rotary hammer includes a spindle 18 which can be rotatably driven by an intermediate shaft 24 by way of a drive device. A tool holder 16 is arranged for rotation with the spindle 18, and for releasably holding a bit or tool for selective rotation and/or reciprocation. A pneumatic hammering arrangement facilitates repeated impacting of the bit or tool for reciprocation within the tool holder (16). A mode change mechanism includes a knob 18 for selectively operating the rotary hammer in any of three modes, identified as a rotary drive only mode, a hammer only mode and a rotary hammer mode.

摘要： A vibratory impact tool for loosening downhole stuck objects in oil or gas wells, utilizing an internal piston spring which is repeatedly compressed by hydraulic pressure, and repeatedly released by lifting a dart valve from a valve seat on a flow-through piston. When the dart valve is lifted from the valve seat by a tripping spring, flow resumes through the piston, quickly lowering hydraulic pressure above the piston, allowing the piston spring to sharply drive the piston against the housing. The dart valve is then reseated on the valve seat, causing the piston to again be driven against the piston spring, rapidly repeating the process.

摘要： A structure for enhancing torque output of an electric drill includes a torque output unit mounted in an inner housing of a torque control unit. The torque output unit includes an intermediate washer located between an internal gear and a locating gear ring to isolate other components behind it from any backward transmitted reaction force that is generated when the electric drill operates, making it possible to use economical plastic instead of expensive powder metallurgic locating gear ring and pinions, and to snap-fit instead of screwing a motor bedplate to a rear end of the inner housing. The locating gear ring is provided with stop lugs to engage with open recesses provided on the inner housing and the internal gear, preventing slippage of the torque output unit in the inner housing even at a large torque output.
