A ball screw is provided having a ball roller screw () and a screw nut () arranged thereon, whereby the balls () are arranged to endlessly circulate in a ball channel () defined by ball tracks () on the ball roller screw () and the screw nut (). The ball channel () includes a load section () wound about the ball roller screw (), the beginning and end of which are endlessly connected by a load-free return section (). A minimum of two and a maximum of four balls () are housed in a common ball cage (), the cage pockets () of which each house one of the balls (), whereby the ball cage () includes discs () at the axial ends thereof and between adjacent balls (), that engage the ball channels (), and provided on the sides thereof facing the balls () with a concave receptacle () for the balls ().

Ball screw

A ball screw drive comprising a spindle nut () that can be disposed on a spindle (), said spindle nut () comprising on an inner periphery, a ball groove () that is arranged along a helix and defines a load-bearing channel () for balls (), an external deflector () arranged outside of the spindle nut () connecting the two ends of the load-bearing channel () endlessly to each other for deflecting the balls () from one of the two ends of the load-bearing channel () to the other of the two ends of the load-bearing channel (), a drive pinion for driving the spindle nut () being arranged on the spindle nut (), wherein the external deflector () is arranged at least substantially within an axial length of the drive pinion.

Ball screw drive

In a spherical plain bearing comprising an inner ring () configured as a spherical body comprising a through-bore, which inner ring () is mounted in an outer ring () through a slide bushing () that surrounds the inner ring (), the outer ring () comprising a spherical inner surface and two diametrically opposite insertion grooves () that start from an end face of the outer ring () and enable the insertion of the inner ring (), the slide bushing () is slipped onto the inner ring () prior to insertion of the inner ring () into the outer ring () and then shaped without chip removal, so that the slide bushing () comes to bear against the spherical outer surface of the inner ring.
