摘要： A chuck configured to be operably coupled to a power driver having a rotatable drive spindle is provided. The chuck (100) may include a body (130) having a center axis (50) and a plurality of clamping jaws (101) configured to clamp onto a working bit. The clamping jaws (101) may be configured to angularly translate relative to the center axis towards or away from a clamping jaw point of convergence (154) to close or open a working bit opening defined by the clamping jaws (101). The clamping jaw point of convergence (154) may be on the center axis. The chuck (100) may also include a plurality of bit alignment jaws (150). The bit alignment jaws (150) may be configured to maintain the working bit within the working bit opening by being configured translate towards or away from a bit alignment jaw point of convergence (153) that is on the center axis (50) and disposed rearward of the clamping jaw point of convergence (154).

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 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.
摘要翻译：卡盘（10）具有主体（14），多个夹爪（22）和可旋转螺母（16）。套筒（18）可相对于螺母在第一旋转位置和第二旋转位置之间旋转。第一齿（84）的环形阵列相对于主体不能旋转。一个或多个第二齿（63）相对于螺母不可旋转并且可相对于主体轴向移动。当齿接合时，它们抵抗螺母在打开方向上的旋转。当套筒从第二旋转位置移动到第一旋转位置时，套筒和一个或多个第二齿之间的接合使一个或多个第二齿与第一齿脱离接合，并且将一个或多个第二齿移动到接合中当套筒从第一旋转位置移动到第二旋转位置时具有第一齿。

摘要： A chuck (600) for use with a powered driver having a rotatable drive shaft is provided. The chuck may include a body, a plurality of movable jaws (610), a nut (625), a sleeve (640), and an anti-vibration assembly (620). The anti-vibration assembly may be operably disposed between the sleeve and the nut and configured to absorb vibration caused by operation of the power driver and maintain a position of the sleeve relative to the nut when the sleeve is in at least a locked position.

摘要： A chuck has a body (14). A plurality of first teeth (96) are rotationally fixed to the body. At least one second tooth (100) opposes the first teeth. The first teeth and the at least one second tooth are configured so that engagement of the first teeth and the at least one second tooth prevents relative rotation between a nut (16) and the body in an opening direction. A sleeve (18) defines a notch (90b) that engages a spring (29) so that in a relative rotational position between the sleeve and the nut, the notch receives the spring so that the notch resists relative rotational movement between the sleeve and the spring in the opening direction of the chuck.

摘要： A chuck (10) for use with a power driver having a rotatable drive spindle. The chuck may include a sleeve (60) comprising a sleeve tightening surface (62) that may be configured to engage with a nut tightening surface (502) to tighten a nut (50) when the sleeve is rotated into a tightening position. With the sleeve disposed in a sleeve locked position, a click pawl (732) may be engaged with a click stopping edge (771) of one of the plurality of click teeth (756) to inhibit rotation of the nut in a first rotational direction to loosen the nut. A lock pawl (722) may also be engaged with a lock stopping edge (761) of one of the plurality of lock teeth (755) to inhibit rotation of the sleeve in a second rotational direction due to the inertia in the sleeve that would tend to further tighten the nut.

摘要： 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 nu t(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.
摘要翻译：提供一种卡盘，用于与具有可旋转驱动轴的动力驱动器一起使用。卡盘包括可移动地设置在圆柱形主体（14）的通道（40）中的多个钳口（22），可旋转地安装在主体（14）周围并与钳口（22）连通的数字（16）螺母（16）在关闭方向上的旋转使钳夹（22）朝向彼此移动，并且螺母（16）沿打开方向的旋转使钳夹（22）彼此远离，并且套筒可旋转地绕着身体（14）。套筒与螺母（16）连通，使得套筒的旋转旋转地驱动螺母（16）。所述卡盘还包括设置在所述螺母（16）与所述套筒的至少一部分之间的偏置元件（208），所述偏置元件构造成将所述套筒朝向中性位置偏置。偏置元件（208）在动力驱动器的操作期间限制施加到螺母的套筒的惯性力。
