    • A keyless chuck is provided, comprising a generally cylindrical body having a forward and rearward portion with respect to an axis, the forward portion including a radially outwardly projecting portion of the body. The body further includes a plurality of guides extending obliquely to the axis and converging toward the forward section, and a groove extending around the body. Each of a plurality of jaws is slidably disposed within a respective guide and includes a thread section along an outer surface thereof. A jaw-engaging mechanism is configured to operably engage the groove so as to be rotatable around the body, and includes a thread section configured to complementarily engage the thread sections of the jaws. A sleeve extends over the jaw-engaging mechanism. A retaining member is disposed substantially within the sleeve, and is operably engaged with and extends between the body and the sleeve, rearwardly of the radially outwardly projecting portion of the body. The retaining member thereby axially constrains the sleeve with respect to movement toward the forward portion of the body. An associated method is also provided.
    • 提供了一种无钥匙卡盘,其包括相对于轴线具有前部和后部的大致圆柱体,前部包括主体的径向向外突出的部分。 主体还包括多个沿轴线倾斜延伸并朝向前部收敛的导向件和围绕主体延伸的凹槽。 多个钳口中的每一个可滑动地设置在相应的引导件内,并且包括沿其外表面的螺纹部分。 夹爪接合机构构造成可操作地接合凹槽以便围绕主体旋转,并且包括构造成互补地接合夹爪的螺纹部分的螺纹部分。 套筒延伸到钳口接合机构上方。 保持构件基本上设置在套筒内,并且与本体和套筒之间的可径向向外突出的部分的后部可操作地接合并在主体和套筒之间延伸。 因此,保持构件相对于朝向身体的前部的移动而轴向地限制套筒。 还提供了相关联的方法。
