摘要： In a drilling device, a tool mounted in the device can be selectively switched from right-hand rotation to left-hand rotation. The tool can be connected to an output shaft on which two conical gear wheels are mounted in spaced relation so that they can be rotated in opposite directions around the output shaft. The teeth on the conical gear wheels face one another and are in meshed engagement with gear teeth on a drive shaft. A coupling part is slidably displaceably mounted on the output shaft and can be engaged with one or the other of the conical gear wheels. The coupling part is secured on the output shaft so that as it is rotated by one or the other conical gear wheels, in turn, it rotates the output shaft in the desired direction.

摘要： A hammer drill includes a unit for supplying impact force to a tool inserted into the hammer drill and a unit for supplying rotational forces to the tool. A first drive motor drives the impact force unit and a second drive motor drives the rotational force unit. The motors can be operated independently of one another. A first drive train interconnects the first drive motor to the impact force unit and a second drive train interconnects the second drive motor and the rotational force unit. A coupling device interconnects the first and second drive trains so that at least one of the impact force unit the rotational force unit can be selectively driven by both the first and second motors.

摘要： A tool holder for securing a drilling or chiseling tool in a device includes a guide tube for receiving the cylindrically shaped shank of the tool. An adjusting sleeve laterally encloses the guide tube and the sleeve is axially and rotatably displaceable relative to the guide tube. When the adjusting sleeve is axially displaced a cam projecting from one of the adjusting sleeves and the guide tube contacts a cam surface on the other for effecting the rotational displacement. The cam surface is inclined relative to the axial direction of the guide tube. Openings extend through the guide tube between its inner and outer surfaces and recesses in the inside surface of the sleeve register with the openings when the sleeve is rotatably displaced. Locking elements are radially displaceably mounted in the openings in the guide tube and secure the tool shank in the holder. These locking elements can move radially outwardly into the recesses in the adjusting sleeve when the sleeve is rotatably displaced for releasing the tool shank from the holder.

摘要： In a hand-held tool having a tool holder for receiving a variety of tool bits, a probing device is provided for checking the surface configuration of the shank of a tool bit inserted into the tool holder. The probing device includes at least one control element arranged to move radially inwardly through an opening in the tool holder. If the control element moves radially inwardly into an axially elongated recess in the tool bit shank, it moves out of stopping engagement with a slide permitting the slide to move relative to the control element and initiating a switching operation for changing the driving action of the hand-held tool.

摘要： In a hammer drill, a striking mechanism supplied percussive force to a tool. The striking mechanism includes a free piston slidably displaceable in a reciprocating manner within a guide cylinder. Balls mounted in the guide cylinder are spring biased into a recess in the free piston for securing the piston in a locked position so that it cannot deliver percussive force to the tool. The balls are spring biased by a ring encircling the cylinder with a spring pressing the ring in the axial direction of the cylinder against the balls.

摘要： A hammer drill can be switched between combined rotary and impact operation and impact operation. An electropneumatic mechanism provides the impact force and includes a guide cylinder with a beveled gear wheel extending around the outside surface of the cylinder. The gear wheel is driven by a drive wheel. A coupling sleeve is mounted on the guide cylinder for rotation with it and is axially displaceable relative to the cylinder between a first position in meshed engagement with the gear wheel and a second position displaced out of meshed engagement. A switching device moves the coupling sleeve between the two positions. In the first position, the coupling sleeve rotates the guide cylinder, while in the second position the guide cylinder is locked against rotation. The switching device includes a control cam engaged within a groove extending in the circumferential direction of the outside surface of the guide cylinder. In the second position of the coupling sleeve, the control cam is moved inwardly relative to the cylinder into one of a plurality of detent openings formed in the base of the groove for locking the guide cylinder so that it does not perform any rotary movement.

摘要： A tool chuck for securing a tool bit in a drilling and cutting device includes a guide tube into which the tool bit is inserted and an adjusting sleeve displaceable relative to the guide tube. The guide tube has spaced first and second apertures with the first apertures holding locking members and the second apertures holding entrainment strips. The adjusting sleeve has alternating first and second pockets in its inside surface for receiving the locking members and the entrainment strips. With a tool bit having slots for both the locking members and the entrainment strip, both the locking members and entrainment strips can be displaced radially inwardly by the adjusting sleeve. If the tool bit has only slots for the locking members, the locking action can be effected with the entrainment strips maintained radially outwardly from the tool bit.

摘要： A drill chuck for a hand-held drilling device, such as a hammer drill, percussion drill or the like, includes a chuck body mounting a plurality of clamping jaws. An adjusting sleeve is rotatably mounted on the chuck body for positioning a partly frusto-conically shaped bracing sleeve for radially positioning the clamping jaws to secure or release a tool shank. The adjusting sleeve includes gear teeth which can be engaged by a ring gear key for rotating the adjusting sleeve relative to the chuck body. A locking sleeve is axially displaceably mounted on the adjusting sleeve. In a first position, the locking sleeve blocks engagement of the key with the ring gear teeth. In a second position, the locking sleeve is moved affording access by the key to the ring gear teeth so that the adjusting sleeve can be rotated and the clamping jaws radially positioned by the bracing sleeve.
