Abstract: 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.

Abstract: 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.
Abstract translation: 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。

Abstract: 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.

Abstract: 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.

Abstract: An anvil for use with a power tool may include a shank and a ram lug. The shank may have a first end and a second end. The ram lug may extend radially from the second end of the shank. The ram lug may include an impact surface configured to receive an impact force from a hammer of the power tool and an impact layer comprising the impact surface. The impact layer may have been formed via a treatment process to have an impact layer depth to an impact layer transitional material interface with an interior region of the ram lug. The impact layer may have a first hardness and the interior region of the ram lug may have a second hardness. The first hardness may be greater than the second hardness.

Abstract: 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).
