Embodiment approach

[0022] refer to figure 1 , the jaw 2 may include a jaw surface 10 and a back surface 4 opposite to the jaw surface 10 . The side surface 6 can extend between the back surface 4 and the jaw surface 10 . By way of example only, two side surfaces 6 may define an angle of 120°, each side surface 6 may be parallel to the side surface of the adjacent jaw. Thus, the side surfaces 6 of adjacent jaws 2 may abut each other when the tool chuck is fully closed. The side surfaces 6 may include chamfers at the jaw faces 10 and / or at the back surface 4 .

[0023] As shown, the jaw face 10 may include a pair of flat portions 12,14. The flat portions 12, 14 may be provided on either side of a jaw axis 90 extending in a radially outward direction from a tool chuck axis 92 extending into the page. The flat portions 12 , 14 may be perpendicular to the jaw axis 90 and parallel to the tool chuck axis 92 . By way of example only, the flat portions 12, 14 may be of the same size.

Abstract

A chuck is described. The chuck may include a plurality of chuck jaws. Each chuck jaw is radially movable toward and away from a chuck axis, and each chuck jaw including: two substantially coplanar surfaces perpendicular to a chuck jaw axis and substantially parallel to the chuck axis; a ridge located between the two substantially coplanar surfaces; and two troughs, one trough located between the ridge and one of the substantially coplanar surface and the other trough located between the ridge and the other coplanar surface. A chuck jaw and a method of configuring a chuck are also described.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Provisional U.S. Patent Application Serial No. 60 / 941,094, "Chuck Jaw Plane Profile," filed May 31, 2007, the disclosure of which is hereby incorporated by reference in its entirety. into this article. technical field [0003] The present invention relates generally to tool chucks for attaching parts to power drivers, and more particularly to jaws of tool chucks for clamping parts. Background technique [0004] Conventional tool chucks may have a body that movably supports the jaws. The tool chuck can be actuated (via a variety of mechanisms) to move the jaws used to grip the part. The jaws can grip a variety of parts including, for example, parts with smooth (or round) shanks, parts with hexagonal shanks (hex shank parts), and parts with round shanks with flats . The surface of the jaw that contacts and grips the part will be referred to as the "jaw face". [0005] The jaw face...
