摘要： A chuck includes a generally cylindrical body, a plurality of jaws and a driving disk. A bearing includes a first race, a second race and a plurality of bearing elements disposed between the first race and the second race. The first race defines a plurality of recesses therein. One of the second race and the bearing elements is disposed in communication with the first race so that, when the jaws close onto a tool and the first race and the second race rotate relative to each other, the one of the second race and the bearing elements engages successive recesses.

摘要： A chuck includes a generally elongated body having a tail section configured to rotate with the drive shaft and a nose section having an axial bore formed therein. A plurality of jaws are movably disposed with respect to the body to and away from the axial bore. A collar in axially driving engagement with the jaws is axially movably disposed with respect to the body so that movement in a first axial direction drives the jaws toward the axis and movement in the opposite direction moves the jaws away from the axis. The collar is configured to receive at least one of the body and a shaft and defines a first surface that faces a second surface defined by the body or the shaft when the same is received by the collar. The first surface is tapered in the axial direction from a first end to a second end of the fist surface so that a first radial distance between the second surface and the first end is less than a second radial distance between the second surface and the second end. A rolling element is disposed between the first and second surfaces and defines a diameter greater than the first radial distance and less than the second radial distance. When an axial force is applied to the collar in the second axial direction, the rolling element wedges between the first and second surfaces.
摘要翻译：卡盘包括大致细长的主体，其具有构造成与驱动轴一起旋转的尾部和具有形成在其中的轴向孔的鼻部。多个钳口相对于主体可移动地设置在轴向孔上并远离轴向孔。与夹爪轴向驱动接合的套环相对于主体轴向移动地设置，使得沿第一轴向方向的运动驱动钳口朝向轴线，并且沿相反方向的运动使夹爪远离轴线移动。套环被配置为接收主体和轴中的至少一个，并且当轴套接收到该轴时，限定面向由主体或轴限定的第二表面的第一表面。第一表面在轴向方向上从第一表面的第一端向第二端渐缩，使得第二表面与第一端之间的第一径向距离小于第二表面与第二端之间的第二径向距离。滚动元件设置在第一和第二表面之间并且限定大于第一径向距离并小于第二径向距离的直径。当在第二轴向方向上向轴环施加轴向力时，滚动元件在第一和第二表面之间楔入。

摘要： A rotary power tool, such as a router, includes an actuating device engaged with a chuck device to move the chuck device between its gripping and release positions. The actuating device includes a lever member that extends axially relative to a casing of the power tool within an inner circumference of a base member. This lever member is movable relative to the casing and is engaged with the chuck so that movement of the lever is imparted to the chuck device causing the chuck device to move axially between its gripping and release positions.

摘要： A quick release chuck device has a body member defining an axially extending bore for receipt of a tool shank. At least a portion of the bore is defined by a plurality of radially compressible and axially extending gripping segments. The gripping segments are equally spaced and defined by axial slots extending from a front face of the body member. At least two axially extending and aligned recesses are defined on each of the gripping segments. An operating member is coaxial with and surrounds at least the gripping segments of the body member. The operating member defines a varying radial width channel with the recesses formed on the outside of the gripping segments. The operating member is axially movable relative to the body member. Actuating elements, such as balls, are disposed within the varying radial width channels. The actuating elements are movable within the channels by axial movement of the sleeve member from a gripping position wherein the balls are in a reduced radial width section of the channels causing the gripping segments to compress radially inward, and a release position wherein the balls move into a greater radial width section of the channels allowing radial expansion of the gripping segments.
摘要翻译：快速释放卡盘装置具有限定用于接收工具柄的轴向延伸的孔的主体构件。孔的至少一部分由多个可径向压缩且轴向延伸的夹持段限定。抓握段由从主体构件的前表面延伸的轴向狭槽间隔开并限定。至少两个轴向延伸和对准的凹部限定在每个夹持段上。操作构件与主体构件的至少夹持段同轴并且至少围绕该构件。操作构件限定了形成在抓握段的外侧上的凹部的变化的径向宽度通道。操作构件相对于主体构件可轴向移动。诸如球的致动元件设置在变化的径向宽度通道内。致动元件可以在通道内通过套筒构件从夹持位置的轴向移动而移动，其中球处于通道的减小的径向宽度部分中，使得抓握段径向向内压缩，并且释放位置，其中球移动到通道的较大的径向宽度部分允许夹持段的径向膨胀。
