摘要： A tool with a transmission assembly having a reduction gearset and a speed selector. The speed selector has a member, an actuator and a shifter assembly. The member is movable between a first position, in which the member is non-rotatable, and a second position in which the member is coupled to a planet carrier of the reduction gearset for common rotation. The actuator includes a pivoting yoke and a follower that is coupled to the yoke. The follower engages the member so as to be axially movable with the follower. The shifter assembly has a selector switch, a switch fork, and a pair of springs. The selector switch is slid able between a first switch position and a second switch position. The switch fork is slidably coupled to the selector switch and receives the yoke. The springs cooperate to bias the switch fork relative to the selector switch into a neutral position.

摘要： A clamping unit for a chuck of a machine tool spindle contains a threaded shaft for adjusting the clamping jaws of the chuck. The threaded shaft is axially adjustable in the clamping unit by means of a threaded nut connected to a rotor of a servomotor actuator. An electrically actuable, releasable clutch has a first clutch element, which is connected in a rotationally secure and axially displaceable manner to the threaded shaft, and a second clutch element, which cooperates with the first clutch element and is connected in a rotationally secure manner to the rotor. When the clutch is activated, the threaded shaft and the threaded nut are mutually connected in a rotationally secure manner and prevent axial displacement of the threaded shaft.

摘要： A power drill has a rotatable spindle extending from a power-unit housing, a chuck body rotationally fixed to the spindle, a jaw guide carried on the chuck body and rotatable relative thereto about the axis, jaws carried in the chuck body, and a pusher element rotatable about the axis in the chuck body and fixed to and bearing axially on the jaws. Screwthreads between the pusher element and the spindle is effective to move the jaws radially on rotation of the spindle about the axis relative to the guide. A coupling sleeve rotationally fixed to the jaw guide is movable between a tightening position rotationally fixed to the housing for movement of the jaws by the pusher element on rotation of the spindle and a drilling position rotationally fixed to the spindle and rotatable relative to the guide for joint rotation of the guide, jaws, and spindle.

摘要： A collet for connecting a tool to a driver includes a shaft having an end. The collet includes a body including a first end that connects to the driver and a second end having an internal space partially defined by a frustoconical bore and a plurality of jaws disposed within the space. Each of the jaws includes a body having a frustoconical surface arranged to engage the frustoconical bore and an engagement member coupled to each body to move between an unlocked and a locked position. Rotation of the tool about the axis in a first direction biases the engagement member toward the unlocked position to allow movement of the tool with respect to the jaws, and rotation of the tool about the axis in a second direction opposite the first direction biases the engagement member toward the locked position wherein the tool is fixed with respect to the jaws.

摘要： The invention relates to a spindle, in particular a machine spindle, which is used to machine a work piece by means of a tool which is applied to the spindle, comprising an axially displaceable tension rod (30) which is used to secure the tool to the spindle, and a drive shaft (4) which is driven, in particular, by the motor of the spindle. The drive shaft of the spindle can be connected via a coupling device either to the tension rod (30) for axially displacing the tension rod (30) in order to change tools or to the tool in order to machine the work piece. The tension rod (30) can be axially displaced in a work shaft (1) which is embodied as a hollow shaft. The work shaft (1) can be arrested in relation to the housing (2) of the spindle in a first coupling position in order to axially displace the tension rod (30) within the work shaft (1) by the drive shaft (4). The angle position of the work shaft (1) and the drive shaft (4) can be freely selected in the first coupling position. A common drive of the work shaft (1) and the tension rod (30) can be produced by the drive shaft (4) in a second coupling position. The angle position of the work shaft (1) and the drive shaft (4) can be freely selected in the second coupling position.

摘要： In a clamping device for machine tools, the device is provided with a power-operated chuck and clamping jaws actuated by a draw rod, the clamping device having an electrical servomotor with a changeover function, a movement converter, and a force accumulator for maintaining clamping force, the movement converter and the force accumulator being integrated in a tube-shaped jacket piece inserted in a housing of the clamping device and divided into two parts connected together. A spindle nut of the movement converter is rotatably supported between the two parts by a projection, and spring packs of the force accumulator are clamped between stop rings and a cover on the jacket piece. The jacket piece is mounted within the housing as to be moved axially by the draw rod via the movement converter. It is possible to determine the clamping force prevailing in the power-operated chuck using only one measuring point.
