DEVICE FOR RADIAL ADJUSTMENT OF TOOLS IN A ROTATING TOOL CARRIER

摘要

A shaving machine for rolled wire or the like wherein the tubular shaving head carries one or moreshaving tools which are caused to move radially in response to axial movement of an adjusting sleeve which is connected to the inner race of an axially movable antifriction bearing spacedly surrounding the shaving head. The outer race of the bearing is provided with annuli of equidistant plenum chambers which are sealed by a stationary ring-shaped guide surrounding the bearing and having conduits for admission of pressurized fluid into the plenum chambers. The plenum chambers serve as a stabilizing or cushioning means for holding the bearing against radial movements with reference to the frame. The adjusting sleeve is loosely coupled to the shaving head so that it rotates with but need not share vibratory or other stray movements of the shaving head. This insures that such stray movements need not be shared by the tools whose supports are biased against a conical internal surface of the adjusting sleeve.
