#CMT# #/CMT# Drill chuck comprises a wedge-like tensioning ring (9) rotating about the chuck body (1) to drive a threaded ring (3). A wedge piece (10) is hinged on the inner side of the tensioning ring using a spring element (12) which pre-tensions the wedge piece. The wedge piece has an inclined wedge surface for blocking the tensioning surface of the chuck body by friction. A control sleeve is connected to an outer sleeve (5) and drives the tensioning ring. #CMT# : #/CMT# Preferred Features: An adjusting jaw (83) and a drive jaw (81) are arranged on the control sleeve. A drive channel is arranged on the tensioning ring for interacting with the drive jaw so that the tensioning ring is rotated. #CMT#USE : #/CMT# Drill chuck for drilling tools. #CMT#ADVANTAGE : #/CMT# The threaded ring remains relative to the chuck body when stationary so that the jaws hold the shaft of a tool using the remaining force. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show front and cross-sections through the drill chuck. 1 : Chuck body 3 : Threaded ring 5 : Outer sleeve 9 : Tensioning ring 10 : Wedge piece 12 : Spring element 81 : Drive jaw 83 : Adjusting jaw. |
