摘要： A rotary hammer includes a spindle that rotates, a reciprocation mechanism including a piston within the spindle and operable to create a variable pressure air spring within the spindle, an anvil within the spindle for reciprocation in response to the pressure of the air spring, the anvil imparting axial impacts to a tool bit, a port in one of the spindle or the piston, and a closure movable relative to the port between a first position, in which the closure member seals the port and an interior volume of the spindle between the piston the anvil is sealed to develop the variable pressure air spring, and a second position, in which the closure member is spaced apart from the port and the interior volume of the spindle between the piston and the anvil is unsealed and unable to develop the variable pressure air spring.

摘要： Disclosed is a striking tool technology that contributes to reducing clutch sizes. The striking tool causes a tool bit to perform a striking operation in the long axis direction and to perform a rotational operation about the long axis, thereby causing the tool bit to carry out a predetermined machining operation. The striking tool comprises a tool body; a motor which is housed in the tool body and drives the tool bit; and a clutch which, on a route where the torque of the motor is transmitted to the tool bit, is disposed in a high rotational speed and low torque region that is a stage prior to where the rotational speed of the motor is reduced, which transmits the torque of the motor to the tool bit in a normal state, and which cuts off the transmission of torque generated about the tool bit long axis in the tool body if the torque exceeds a predetermined torque level.

摘要： A machine tool with a tool holder which is equipped to mount a tool, such as a chiseling tool, moveably along a movement axis. A striking mechanism contains a primary drive, arranged around the movement axis, containing at least one magnetic coil. The striking mechanism has a striker and an anvil arranged within the magnetic coil on the movement axis in sequence in the impact direction. The anvil protrudes at least partially into the magnetic coil. In addition, the striking mechanism can have an air spring affecting the striker in the impact direction. A controlled power source forms an electrical circuit in which a current flows, controlled at a target value, from the power source and into at the at least one magnetic coil during an acceleration phase. A controller ends the acceleration phase when a change, typical for an impact, is detected in the current flowing in the magnetic coil or a change, typical for an impact, is detected in a control variable of a control circuit of the power source.

摘要： A hand-held power tool, in particular a rotary hammer, is indicated that includes a machine housing (10) with a tool fitting (12) integrated therein, the tool fitting (12) being rotatably drivable in a first mode and being non-rotatably fixable on the machine housing (10) in a second mode, and that includes a duty-type switch (20) with a coupling element (21) capable of being displaced to activate the modes, and an actuating element (22) that induces its displacement. To prevent maloperation and resultant damage to the machine when the operator switches between modes, the actuating element is designed as an electrical actuator (23), preferably as an electromagnet (25) controlled by an electronic control unit (24).
