ABSTRACT:
The rolling nut for transforming a rotary movement of a smooth shaft into a thrust movement of the nut comprises a tubular housing in which a number of roller cages defining a center passage for the shaft and engaging an arcuate surface portion of the shaft are arranged. The roller cages are inclined to the axis of the shaft and to each other. Wedge-shaped distance rings are arranged between the neighboring roller cages and laterally of the end roller cages. The roller cages and the distance rings are interchangeable within the housing so that the direction of the angle of inclination of each roller cage within the housing can be varied.
