FIELD: machine building.
SUBSTANCE: invention relates to a rotation-to-longitudinal motion converter. The converter comprises a threaded rod on which a nut (2) is mounted with the possibility of movement along the threaded rod axis, and at least one lock member. The lock member stops the rotation of a nut (2) at its movement along the threaded rod (3) which is fitted by at least end stop (10a, 10b) limiting the movement of the nut (2) along the threaded rod (3). A pair of bevel washers (1a, 1b) is installed between the nut (2) able of longitudinal motion and the end stop (10a, 10b). The pair of bevel washers (1a, 1b) is made so that the bevel washers (1.1, 1.2) are engaged with each other by pressing the nut (2) to the end stop (10a, 10b) and provide for a preload torque. The torque for disengagement of the nut (2) and the end stop (10a, 10b) is less than the torque for pressing the nut (2) to the end stop (10a, 10b) at the moment of preloading the pair of bevel washers (1a, 1b).
EFFECT: it is provided for the decrease of disengagement torque in respect to the tightening torque at the contact of the nut and the end stop.
