Abstract: A recirculating ball screw and nut drive including a spindle, a spindle nut guided on the spindle, balls guided between the spindle and the spindle nut, in a working passage defined by grooves of the spindle and spindle nut, and deflection pieces arranged on both ends of the spindle nut to divert the balls out of the working passage into a return passage accommodated in the spindle nut, and to divert the balls out of the return passage into the working passage accommodated in the spindle nut, where the ball deflection pieces are annular and composed of at least two circular-ring sectors.

Abstract: Apparatus for screw transmission on a spindle comprising a nut having at least a first and second part with internal threads, at least one bore in the first and second parts, and at least one spring located within the at least one bore of the first and second parts and arranged with a bending load acting crosswise to a longitudinal direction of the bore. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Ball screw drive including threaded spindle and threaded nut body. Nut body is axially displaceable on spindle, and threaded grooves of the spindle and the nut body are arranged to form load-bearing ball channel. Return channel is provided, as is plurality of balls for movement through load-bearing ball channel and return channel. Return channel is structured so that balls moving through return channel are not under stress. At least one of spindle and nut body have at least one additional groove parallel to load-bearing channel, and return channel includes the additional groove. End caps arranged at opposite ends of nut body are structured and arranged to transfer balls from load-bearing ball channel to return channel and from return channel to load-bearing ball channel. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
