摘要： A drill chuck and a drill apparatus is provided that includes a drilling machine, which has a motor and a machine spindle that is supported in rotary fashion in a machine housing. The a drill chuck is connected to the machine spindle and can be moved between a clamping configuration and a drilling configuration and has a clamping sleeve and a chuck body in which clamping jaws are movably guided by a threaded connection. When a sliding sleeve is moved relative to the chuck body between a first position that corresponds to the clamping configuration and a second position that corresponds to the drilling configuration, a flow of force traveling from the motor via the machine spindle to the threaded connection is shifted to a flow of force traveling from the motor via the machine spindle to the chuck body and vice versa.

摘要： A chuck including a body having a nose section, a tail section and a center axis, the nose section defining an axial bore and a plurality of passageways. A plurality of jaws is disposed in the passageways, a nut is rotatably mounted about the body so that rotation of the nut either moves the jaws toward or away from the center axis, and a sleeve that is rotatably mounted about the body, the sleeve being rotatable with respect to the nut between a first rotational position and a second rotational position. An annular array of locking teeth is non-rotatable with respect to one of the body and the nut. A lock ring includes at least three projections and is axially movable so that, when engaged, the projections and the locking teeth resist the lock ring from rotating in the opening direction with respect to the body.

摘要： A power tool having a tool portion, a chuck and a lock. The tool portion has a housing, a motor, and a spindle driven by the motor. The chuck has a body coupled to the spindle for rotation therewith, and a sleeve rotatably disposed about the body. The lock has a first lock structure pivotally coupled to the housing about a pivot axis, and a second lock structure. The first lock structure has a first locking feature. The second lock structure has a second locking feature and is coupled to the sleeve for rotation therewith. Pivoting the first lock structure into a first pivot position positions the first locking feature in a rotational path of the second locking feature. Engagement of the first and second locking features inhibits rotation of the sleeve so that rotation of the spindle will cause corresponding rotation of the body relative to the sleeve.

摘要： A power drill has a housing holding a motor and a drive member rotatable about an axis. An arbor extending along the axis outside the housing is rotationally coupled by complementary formations with the drive member. A tube shaft on which is fixed a chuck body holding a plurality of axially displaceable jaws. A sleeve in the tube shaft is rotationally coupled to the arbor. A pusher element braced axially forward against the jaws extends axially rearward into the sleeve, and interengaging screwthreads on the sleeve and pusher element axially displace the pusher element and the jaws on relative rotation of the sleeve and pusher element. A setting sleeve rotationally coupled to the rear end of the tube shaft is axially displaceable between a tightening position engaging a slip coupling on the housing and a drilling position disengaged from the slip coupling and rotationally coupled to the arbor.
