摘要：This invention pertains to a gmented expanding sleeve for an expanding mandrel or chuck in which air or hydraulic fluid is fed to and into a resilient tube or tubes arranged in a longitudinal or in a helical manner. This tube or the tubes are carried by and in grooves formed in the body and when pressurized air or fluid is fed into the tube means the tube or tubes are expanded in a controlled manner to outwardly move a plurality of like-linked leaf members or gments. Each leaf member has one longitudinal edge formed with a keyhole-type groove and the other edge of each leaf is formed with a tongue member having an enlarged outer portion. In an asmbled condition the tongue member of one leaf is mounted in the keyhole groove of the next adjacent leaf and the tongue and groove arrangements provide an outer limit to the expansion. Resilient inner tying members extend between leaf members and retain and draw the leaf members into an inner limit against the body of the chuck. Usually one or more of the leaf members are mounted on pins carried in the body. The pins transmit the torque from the outer leaf members to the core member and vice versa.最长的英文单词
