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 tail section defining an annular shoulder and a nose section having an axial bore and angularly disposed passageways intersecting the axial bore. An O-ring is disposed in the annular shoulder and a plurality of jaws is slidably positioned in the passageways. A nut is rotatably mounted on the body in engagement with threads on the jaws. A first sleeve and a second sleeve each define a gripping surface thereon and one of the first and second sleeves is axially reciprocal on the body. The one of the first and second sleeves defines an annular groove on an inner surface thereof having a first shoulder and a second shoulder. The O-ring is received in the groove such that axial motion of the one of the first and the second sleeve is limited by abutment of the O-ring with said first and second shoulders.

摘要： A chuck for use with a manual or powered driver having a housing and a rotatable drive shaft extending therefrom is provided. The chuck includes a generally cylindrical body member having a nose section and a tail section. Each of a plurality of jaws is slidably positioned in one of a plurality of angularly disposed passageways in the body. Each jaw has a jaw face formed on one side thereof and threads formed on the opposite side thereof. A nut is rotatably mounted on the body in engagement with the jaw threads so that rotation of the nut moves the jaws axially within the passageways. A locking member, in a first axial position, is rotatable with respect to the driver housing. In a second axial position, it operatively engages the housing and the nut so that the locking member is rotationally held to the housing and the nut so that the nut is rotationally held to the housing. The locking member is axially reciprocal between the first axial position and the second axial position.

摘要： A drill has a housing, a drivable drill spindle rotatably mounted in the housing, a chuck body coaxially connected and rotationally fixed to the drill spindle, a tightening sleeve rotatable on and relative to the chuck body, and jaws moveable relative to the chuck body by the tightening sleeve. A coupling between the housing and the tightening sleeve has a sleeve held on the housing so as not to rotate with the chuck body and movable relative to the chuck body chuck between a coupling position in which it connects the tightening sleeve to the spindle housing angularly in a friction-fit manner and a decoupling position into which it is urged by a decoupling spring when torque between the tightening sleeve and the coupling sleeve in the coupling position exceeds a predetermined value.
