摘要： A chuck (10) is provided that includes a plurality of jaws (20) and a body (30) configured to rotate with a drive spindle of a power driver. The chuck (10) may also include a nut (80) comprising nut teeth (82). The nut (80) may be operably coupled to the jaws (20) and configured to move the jaws (20) relative to the body (30) in the opening or closing direction. The chuck (10) may also include a clutch (100) comprising clutch teeth (102). The clutch (100) may be configured to move between a working position and a jaw actuating position. In the working position, the clutch teeth (102) may be engaged with the nut teeth (82) to prevent movement of the nut (80) relative to the body (30), and, in the jaw actuating position, the clutch teeth (102) need not be engaged with the nut teeth (82) and the nut (80) may be free to move relative to the body (30).

摘要： A drill chuck assembly. The drill chuck assembly includes a rapid change mechanism configured to retain a drill bit shank inserted therein. The drill chuck assembly includes a body having a bore with a trilobe cross-section that is configured to receive a triangular and hexagonally shaped drill bit shank, interchangeably. The bore includes a slot positioned in each lobe that slidably contains a detent ball therein. A collar is affixed annularly around the body and defines a channel extending around the body. A sleeve is slidably mounted around the body. The sleeve includes a tapered end that is slidably disposed within the channel and has circular apertures that are in communication with the slots of the bore for reception of the detent balls. The sleeve is spring biased towards the collar, which forces the detent balls against an angular wall within the channel. The angular wall in turn forces the detent balls laterally towards a center of the bore, thereby exerting a force on a drill bit shank inserted into the bore and preventing the withdrawal of the shank from the bore. When the bias force of the sleeve is counteracted by sliding the sleeve about its longitudinal axis, the detent balls move outwardly along the angular wall, thereby relieving the force exerted onto the shank by the wall and allowing the shank to be withdrawn.

摘要： A self-locking drill chuck is disclosed herein. Among the rotating sleeve, the spring leaf and the nut, the nut is rotated by the rotating sleeve without being driven by the spring leaf, the spring leaf is loaded on the nut to rotate with the nut synchronously, under normal state, the locking end of the spring leaf is in a closed state against the teeth, and the self-locking drill chuck is also provided with a state switching part which is connected with the rotating sleeve and rotates with the rotating sleeve synchronously; the spring leaf is provided with a state switching matching structure. The nut is directly driven by a rotating sleeve without the spring leaf during the rotating process in the clamping direction or the releasing direction, which can enhance the hand feeling and efficiency in the clamping operation; the spring leaf has self-locking functions which can be in normally closed and the elastic force is opposite to the centrifugal force, greatly enhancing the reliability of the drill chuck self-locking structure.

摘要： A chuck including a body with a nose section defining an axial bore formed therein, a plurality of jaws movably disposed with respect to the body, and a sleeve rotatably mounted about the body so that rotation of the sleeve moves the jaws relative to the axial bore. A bearing has a first race, a second race, and at least one bearing element disposed therebetween, one of the first race and the second race defining a ratchet and the other defining a pawl biased toward the ratchet. A biasing element is disposed between the pawl and the sleeve. The biasing element exerts a biasing force on the pawl toward the ratchet and the ratchet and the pawl prevent the second race from rotating in the opening direction with respect to the first race when engaged.

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.
