Chuck with slip protection
A chuck is provided for use with a powered driver having a rotatable drive shaft. The chuck includes a plurality of jaws movably disposed in passageways of a cylindrical body, a nut rotatably mounted about the body and in communication with the jaws such that rotation of the nut in a closing direction moves the jaws toward each other and rotation of the nut in an opening direction moves the jaws away from each other, and a sleeve rotatably mounted about the body. The sleeve is in communication with the nut such that rotation of the sleeve rotationally drives the nut. The chuck also including a biasing element disposed between the nut an at least a portion of the sleeve configured to bias the sleeve toward a neutral position. The biasing element limits an inertial force of the sleeve applied to the nut during operation of the powered driver.
