A support nut in machine elements of the screw-spindle/nut comprising a supporting device which extends along the machine element for the purpose of preventing the occurrence of natural vibrations therein. The support nut (6) includes a ball race (7) which is arranged coaxially with the spindle. The ball race is provided with mutually parallel grooves (8), which extend transversely to the axis (9) of the ball race and the spindle, and balls (10) which run in the grooves (8) and in the screw threads of the spindle. A ball-retainer (11) is arranged coaxially between the ball race and the spindle and is freely rotatable in relation to the ball race (7), and a nut-section (12) is arranged coaxially around the ball race (7). A locking element (22, 22 min ) is arranged between the nut-section (12) and the ball race (7), such as to enable the ball race to rotate relative to the nut-section (12) subsequent to exceeding a predetermined torque between the ball race (7) and the nut-section (12). |
