CARRIER DEVICE Russian patent published in 2007 - IPC B23B33/00 

FIELD: manufacturing processes in machine engineering, working shafts in lathes, circular grinders and gear milling machine tools.

SUBSTANCE: carrier device includes body in which stationary center is arranged and pins of spring-loaded carrier members are mounted. In order to improve accuracy of working, to increase rigidity of carrier device and to increase torque, carrier members are self-aligned ones and they have floating hemispheres designed for transmitting torque to worked blank along carrier surfaces preliminarily formed in its end.

EFFECT: improved accuracy of working, enhanced rigidity of device, high torque transmitted to blank.
