摘要：A drill chuck (50) includes a chuck actuating shaft (64) and a chuck actuating screw (55) which are rotated about a chuck axis (178). The chuck actuating shaft has a threaded aperture for receiving a threaded portion (180) of the chuck actuating screw. Rotation of the chuck actuating shaft relative to the chuck actuating screw translates jaws (J) so that the jaws converge or diverge from the chuck axis. The chuck further includes a device (170, 172, 174) coupled to at least one of the chuck actuating screw, the chuck actuating shaft, and an input shaft (not shown, see figure 4) for limiting elastic elongation of the chuck actuating screw in an axial direction when the jaws are fully opened.
