摘要： A hammer drill has a chuck forming a tool receptacle defining a chuck axis and provided with a tool-holding element radially displaceable into a position protruding into the tool receptacle. The tool has a shank defining a tool axis receivable axially in the receptacle. This shank is formed with a radially outwardly open recess closed at both of its axial ends and shaped to receive the tool-holding element, and with an axially extending groove separate from the recess and open axially at a free end of the shank. At least a section of the shank has a conical shape decreasing in a direction towards the free end of the shank. The shank may be provided with at least one cylindrical guiding section located adjacent to the above conical section.

摘要： A torque-transmitting system, particularly a hammer drill, has a housing provided with a tool holder section, and a driven output shaft which is journalled in the housing and has a free end portion at the tool holder section. A tool has a shaft provided with an end portion of profiled cross-section, the profiling of the cross-section being inclined circumferentially of the end portion. A receiver for the end portion is formed in the tool holder and configurated for matingly receiving the profiled end portion, so that the tool is held in the tool holder section in motion-transmitting relationship with the free end portion of the shaft.

摘要： A device on hand machine tools is suggested for the transmission of torque to percussion drilling tools in which at least two rotary driving grooves open out at the end of the tool shaft and strip-shaped rotary drivers of the tool shaft engage in these rotary driving grooves and include assigned flanks, which are at least approximately planar, and in which locking members are arranged in the tool receptacle and cooperate with two recesses in the tool shaft which are closed on both sides and lie diametrically opposite one another. In order to avoid incorrectly reversed insertion of tools with driving grooves which are worn out due to intensive wear, the latter are distributed along the circumference of the tool shaft in such a way that two rotary driving grooves can in no case lie diametrically opposite one another.

摘要： In a drive-in apparatus for driving fasteners such as clips, nails, tacks, staples and the like in a workpiece, a solenoid for actuating impact blade which ejects the fastener is movably arranged in the apparatus housing. The solenoid includes an exciter coil formed with a central opening in which a cylindrical armature connected to the impact blade is magnetically accelerated in forward direction and returns to the starting position by a resetting spring. The exciter coil is also movably guided within the housing and spring biased in the forward direction by another biasing spring having a progressive elasticity characteristic. Depending on the steepness of the characteristic line of the second biasing spring, the backstrokes of the apparatus and the force necessary for tacking operation can be adjusted in broad range.

摘要： A hand-held power tool, particularly a chipping tool has an impact-damping arrangement for damping axial impacts of a striking member against a working tool. The arrangement includes a shaped member which is firmly and axially movably held on an outwardly extending portion of the tool and constituted by an elastic material. The shaped member has a substantially radial abutment face which abuts against a face of a tool holder in striking and noise-damping manner and radially overlaps an opening of a receiving recess of the tool holder so as to serve simultaneously for protection from dust.

摘要： A hand-held power tool has a tool holder for holding a tool, a striking mechanism including a cylindrical sleeve, a drive piston reciprocable in the sleeve, and a striker actuated by the latter, and a drive motor located axially parallel with and laterally adjacent to the cylindrical sleeve. The drive motor transmits the movement to the striking mechanism through a crank drive which is a one-stage crank drive and has a drive train extending transversely to a longitudinal axis of the cylindrical sleeve. The crank drive includes a rotatable shaft, a bevel gear fixedly mounted on one end portion of the drive shaft and meshing with a drive pinion of the motor, and a crank lever mounted on the other end portion of the drive shaft and connected with the drive piston of the striking mechanism. A fan is mounted on the motor shaft and operative for aspirating air, so that air flows through the motor, then flows around the cylindrical sleeve of the striking mechanism and then discharges toward the tool holder.
