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 for use with a power driver having a rotatable drive spindle is provided. The chuck may include a clamping assembly comprising a clamping member that operably couples the sleeve to a nut. The clamping assembly may be configured to transition the chuck between a rapid jaw adjustment mode and a clamping mode. In the rapid jaw adjustment mode, a sleeve may be configured to rotate the clamping member with the nut to cause rotational movement of the nut relative to jaws and a chuck body, which may cause translational movement of the jaws relative to the chuck body. In the clamping mode, the nut may be rotationally fixed with the jaws and the clamping member may rotate relative to the nut to cause the nut to move axially relative to a center axis of the chuck which causes the jaws to translate relative to the body and clamp onto a working bit.

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。

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.
