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 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 () comprising a return channel () for the balls () being arranged on an outer periphery of the spindle nut (), said external deflector () comprising two ball openings (E, E), each of which is connected to an end of the load-bearing channel () to deflect the balls () from one end of the load-bearing channel () to the other end of the load-bearing channel (), the external deflector () extends from one of the two ball openings (E) to the other of the two ball openings (E) at least approximately over one full winding about an axis of rotation of the spindle nut ().
