Abstract (en)
[origin: WO2012160149A1] The invention relates to a concept for a nut or a spindle for a roller screw drive, characterized in that the nut or the spindle comprises a thread turn (110) that is designed to guide rolling elements (120) along a thread in such a way that the rolling elements (120) are in engagement with the thread of the spindle or of the nut and force is transmitted between the nut and the spindle. The thread turn (110) is designed to return the rolling elements (120) to a return channel and to receive the rolling elements (120) from the return channel. The thread turn (110) is further designed to unburden the rolling elements (120) from the force transmission before being returned to the return channel and/or to load the rolling elements (120) with the force transmission only after being received from the return channel.
