摘要： A chuck includes a driver disposed on a chuck body and in engagement with the jaws so that at least one of rotation and axial movement of the driver with respect to the body opens or closes the jaws. A first detent is disposed in the body in communication with the jaws. At least one of the jaws defines a catch at a predetermined position so that the catch engages the first detent when the jaws are at a predetermined position on the body with respect to a chuck bore.

摘要： In construction of a keyless tool chuck in which clamping torque is transmitted from a manually rotatable operation sleeve on a chuck body to tool clamping jaws in the chuck body via a power transmission unit including a cycloidal gear arrangement, an elastic impulsion sleeve is inserted between the operation sleeve and the chuck body so that elastic compressive deformation of the impulsion sleeve at forced rotation of the operation sleeve causes impulsive meshing engagement in the cycloidal gear arrangement to provide impulsive clamping force on a tool clamped by the jaws. Resultant clamping force is at least twice as large as that provided by a conventional cycloidal gear arrangement only.

摘要： The present invention has an object of providing a rotation output device, including a lock mechanism employing a movable lock member so as to define the lock position, which is capable of, when the operator operates an output shaft to pivot, preventing the movable lock member from being concomitantly rotated with the output shaft and thus providing a locking function with certainty. The rotation output device according to the present invention includes, between the lock gears 35 and the lock ring 33, a carry plate 37 for retaining the positions of the lock gears 35 in the rotation direction when receiving a rotation force from the center ring 32. Thus, the lock ring 33 which is rotational-fixed is used as a member for preventing the concomitant rotation of the lock gears 35.

摘要： A lock device of output shaft capable of stopping the output shaft quickly when the output shaft is controlled to stop, and locking to prevent the output shaft from rotating when the output shaft side is stopped against the drive side. The output shaft is formed by connection of drive shaft and driven shaft. Play for a specific angle is formed in mutual rotating direction, at a junction of connection of the drive shaft and driven shaft. A holding plate is fixed to the driven shaft side confronting the drive shaft in the axial center direction. An annular lock ring forming a lock pawl on the outer circumference is held movably to concentric position and eccentric position, at the holding plate side. A lock operation member is provided in the drive shaft confronting the lock ring, for allowing the lock ring to move to the concentric position when the play at the junction of the drive shaft and driven shaft is eliminated by initial rotation of rotation of drive shaft, and allowing to move to the eccentric position when rotation of the drive shaft is stopped to return a play at the junction by reaction. A internal ring forming a pawl for locking mutual rotation by mutually engaging with the lock pawl on the outer circumference of the lock ring when the lock ring is moved to the eccentric position is formed oppositely on the outer circumference of the lock ring.
