A chuck (10) has a body (14), a plurality of jaws (22), and a rotatable nut (16). A sleeve (18) is rotatable between a first rotational position and a second rotational position with respect to the nut. An annular array of first teeth (84) are non-rotatable with respect to the body. One or more second teeth (63) are non-rotatable with respect to the nut and axially movable with respect to the body. When the teeth engage, they resist the nut's rotation in the opening direction. An engagement between the sleeve and the one or more second teeth moves the one or more second teeth out of engagement with the first teeth when the sleeve moves from the second rotational position to the first rotational position and moves the one or more second teeth into engagement with the first teeth when the sleeve moves from the first rotational position to the second rotational position.

A chuck including a chuck body that supports a plurality of jaws. An outer sleeve is axially fixed with respect to the chuck body. A nut is coupled to the outer sleeve, and the nut is movable axially and radially relative to the chuck body. The nut interacts with the jaws such that when the outer sleeve rotates, the nut moves axially and radially relative to the body.

A power tool chuck includes a body with a central bore extending along an axis and configured to receive a tool bit, a plurality of angled passageways, and a plurality of jaws received in the passageways and moveable between an axially forward and radially inward clamping position and an axially rearward and radially outward retracted position. At least one jaw has a rear end lying in a first plane transverse to the axis. A first key drive member coupled to a tail portion of the body is configured to be engaged by a second key drive member on a power tool output shaft to non-rotationally couple the body to the output shaft. The first key drive has a forward end lying in a second plane transverse to the axis. The second plane is axially forward of the first plane when the jaws are in the retracted position.

A drill chuck is disclosed in the present invention. A ring body that can be expanded and deformed outwardly and recovered inwardly is disposed between the ring of steel balls at the back of the nut and the rotary sleeve, the ring body has a portion abutted by steel balls and an outer portion engaged with the rotary sleeve or a part fixedly coupled to the rotary sleeve after the ring body is expanded and deformed outwardly, there is a gap between the outer portion and the rotary sleeve or the part fixedly coupled to the rotary sleeve when the drill chuck is not working, and the gap is within the deformation range of the ring body, a steel ball pushing structure that relies on the back thrust generated when the drill chuck is working is formed between the nut and the support structure, such that the steel balls can push outwardly to expand and deform the ring body outwardly. The present invention has a simple structure, and can resist inertia and prevent loosening of the rotary sleeve on the basis of the original structure of the drill chuck, such that the drill chuck can maintain the original working state during the drilling work.

A chuck includes a body having a nose section with an axial bore and a plurality of passageways formed therein, and a plurality of jaws disposed in the passageways. A nut for driving the jaws is rotatably mounted about the body and a sleeve defining a first recess and a second recess is rotatable with respect to the nut between a first rotational position and a second rotational position. An array of locking teeth is fixed to the body and a pawl member with an engagement portion is non-rotatably fixed to the nut. The engagement portion is received in the second recess and engages the locking teeth when the sleeve is in the second rotational position, the engagement portion being compressed so that an amount of force is exerted on the nut in the closing direction by the engagement portion.

A chuck is provided for use with a powered driver having a rotatable drive shaft. The chuck includes a plurality of jaws (22) movably disposed in passageways (40) of a cylindrical body (14), a nut (16) rotatably mounted about the body (14) and in communication with the jaws (22) such that rotation of the nut (16) in a closing direction moves the jaws (22) toward each other and rotation of the nut (16) in an opening direction moves the jaws (22) away from each other, and a sleeve rotatably mounted about the body (14). The sleeve is in communication with the nut (16) such that rotation of the sleeve rotationally drives the nut (16). The chuck also including a biasing element (208) disposed between the nut (16) an at least a portion of the sleeve configured to bias the sleeve toward a neutral position. The biasing element (208) limits an inertial force of the sleeve applied to the nut during operation of the powered driver.

A power tool chuck includes a body with a central bore extending along an axis and configured to receive a tool bit, a plurality of angled passageways, and a plurality of jaws received in the passageways and moveable between an axially forward and radially inward clamping position and an axially rearward and radially outward retracted position. At least one jaw has a rear end lying in a first plane transverse to the axis. A first key drive member coupled to a tail portion of the body is configured to be engaged by a second key drive member on a power tool output shaft to non-rotationally couple the body to the output shaft. The first key drive has a forward end lying in a second plane transverse to the axis. The second plane is axially forward of the first plane when the jaws are in the retracted position.

A chuck for a power tool includes a chuck body extending along a longitudinal axis. The chuck also includes a plurality of jaws, each with a jaw end, and each movable along a respective jaw axis between a closed position and an open position. Each respective jaw axis is oriented at an oblique angle relative to the longitudinal axis. A biasing member is coupled to the jaws and is operable to bias the jaws toward the closed position. The biasing member includes a spring. The chuck also includes a rotating assembly selectively engageable with the jaws such that, when engaged, the jaws are movable in response to rotation of the rotating assembly. The biasing member includes a guide sleeve coupled to each of the jaws and movable axially along the longitudinal axis in response to each of the jaws moving along its respective jaw axis.

A drilling chuck for operation on an impact drilling spindle, which can be subjected to tangential loading, with a chuck body, which is connected or connectable to the impact drilling spindle in which jaw guides are formed, which run inclined to the chuck axis in which jaw guides and clamping jaws are guided, which can be adjusted by a threaded ring, with a clamping sleeve, which can be coupled in a torque-transmitting manner to the threaded ring, and with a locking device, which is adjustable between a release configuration, which enables a relative rotation of the threaded ring with respect to the chuck body and a locking configuration, which obstructs or prevents this relative rotation. The locking device is formed from a locking sleeve, which is mounted essentially rotationally fixed but axially displaceable with respect to the chuck body, which comprises at least one locking member.
