Abstract

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.
