Title:
A CHUCK DRIVED BY FLEXIBLE WHEEL
Document Type and Number:
WIPO Patent Application WO/2008/040165
Kind Code:
A1
Abstract:
A chuck drived by flexible wheel includes a drill body (1), several jaws (2), a transmitting
nut (3), a controlling outer sleeve (7) and a harmonic drive device with flexible
wheel positioned between the transmitting nut and the controlling outer sleeve.
Due to the harmonic drive device, the chuck could transmit the turning moment
to the nut through the incremental force of the gear transmitting with the help
of the formation of the harmonic waves rule about the flexible wheel. So the clamping
force of said chuck is distinctly greater than the common chuck.
