摘要： A chuck for fixing a rotary tool such a drill and an end mill to a machine tool is disclosed. This chuck comprises a main body comprising a taper shank for fixing the chuck to the machine tool and a tool support for clamping the rotary tool, a fastening ring for regulating fastening force by the tool support, a needle roller bearing interposed between the fastening ring and the tool support under an inclined state, and a gear mechanism for rotating the fastening ring. This gear mechanism comprises, for example, a worm wheel formed integrally with the fastening ring and a worm engaging with the worm wheel. When this structure is employed, the rotary tool can be fitted to and removed from the chuck without fixing a spindle of the machine tool, and the fastening ring can be turned without a great force.

摘要： In a chuck comprising a holding cylinder having a tapered outer circumferential surface and an objective tool or an adapter for holding such a tool inserted therein, and a clamping cylinder rotatably mounted at a predetermined distance from the outer circumferential surface of the holding cylinder, a number of needle rollers being arranged in a plurality of stages along the entire circumference of a gap between the two cylinders to extend along a direction at a predetermined inclined angle .alpha. with respect to the common axis of the cylinders, and the needle rollers rotating and revolving upon rotation of the clamping cylinder, thereby contracting and recoverying the holding cylinder, slits are formed in the holding cylinder to allow elasticity of the holding cylinder and to improve oil throwing performance and clamping force of the holding cylinder. The slits will not interfere with smooth rotation of the needle rollers.In another invention, communication between the inner and outer circumferential surfaces of the holding cylinder through the slits is blocked by seal members so as to prevent egress of dust or cutting chips onto the outer circumferential surface of the holding cylinder through the slits, and to allow smooth rotation of the needle rollers.

摘要： A keyless chuck adapted to grip an object, such as a drill bit, is disclosed. The keyless chuck includes a cylindrical body provided with an axially extending tapered bore. The surface of the tapered bore includes first and second cam surfaces. A control sleeve is provided surrounding at least a portion of the cylindrical body and is adapted for controlled axial movement relative to the cylindrical body. A retaining element is attached to the control sleeve and partially closes one end of the cylindrical body. A thrust bearing is provided in the retaining element. Gripping elements are positioned within the tapered bore and are adapted to engage and grip the tool when the tool is inserted between the gripping elements. A thrust bearing is positioned in the retaining element which operatively engages the gripping elements. A spring retains the gripping elements in contact with the tapered bore and also with the thrust bearing wherein, upon axial movement of the control sleeve relative to the cylindrical body, the gripping elements move axially within the tapered bore in contact with the first cam means, thereby causing radial movement of the gripping elements and wherein, upon rotation of the cylindrical body relative to the gripping elements, the gripping elements shift along the surface of the second cam and thereby also cause radial movement of the gripping elements.

摘要： A chuck includes a holder body, a clamp sleeve, and a large number of needle rollers. The holder body has a shank portion, a flange, and a chuck sleeve. The clamp sleeve is fitted onto the outer circumference of the chuck sleeve such that the clamp sleeve is rotatable and axially movable relative to the chuck sleeve. The needle rollers are disposed between the chuck sleeve and the clamp sleeve over the entire circumference. The clamp sleeve is rotated to cause the needle rollers to revolve spirally along the outer circumferential surface of the chuck sleeve while rotating about their own axes in order to decrease and restore the diameter of the chuck sleeve. A thrust member is disposed between the end surface of the flange opposite the shank portion and a corresponding end surface of the clamp sleeve.

摘要： In a support device to hold a tool or a workpiece, a tightening cylinder is provided at inside with an insertion hole for a substance to be held and on an outer circumference with a taper surface, a rotary cylinder is rotatably and externally fitted to outside of the tightening cylinder through a number of rollers, the rotary cylinder is rotated thereby the rotary cylinder is moved towards diameter side of the tightening cylinder and the tightening cylinder is contracted so as to tighten the substance to be held. Since a number of strain absorbing holes are provided on the inner circumferential surface of the tightening cylinder and scattered uniformly in the axial direction and in the circumferential direction, the deflection adaptability of the tightening cylinder is high and the tightening cylinder can be contracted by a relatively small force.
