ABSTRACT:
A spindle and a spindle nut having external and internal threads, respectively, formed thereon and circulating balls operatively engaged between said threads operating to effect transmission of forces axially thereof when the spindle and spindle nut are rotated relative to each other. The balls are circulated through ball ducts formed by the threads and by the circulating means which return the balls from ball duct outlets of the threads to ball duct inlets thereof. Compensating means for enabling adjustment of the operating pressure between the spindle and the spindle nut by adjusting the diameter of the spindle nut enable compensation of the degree of play which is developed between the balls and the ball ducts through which the balls are circulated. In one aspect of the invention, the spindle nut is formed with a longitudinal slit thereby enabling adjustment of the diameter of the spindle nut and of the pressure by which it is engaged about the spindle.
