Description

(54) ШАРИКОВИНТОВАЯ ПЕРЕДАЧА(54) BALL TRANSMISSION

Изобретение относитс  к машиностроению и может бьугь использовано в механиз мах, преобразующих вращательное овиженне в поступательное. Известна шариковинтова  переиача, соцержаща  винт, гайку, шарики, { асположениые в канавках винта и гайки, устройство дл  возврата шариков, вьтолнеиное в вт. де вклацьпиа, размешенного в теле гайки 1|, Из известных шариков интовых переаач наиболее близкой к изобретению  вл етс  шариковинтова  передача, содержаща  винт гайку, шарики, расположенные в канавках винта и гайкн, устройство дл  возврата ша риков, выполненное в виде V -образной трубки, концы которой размещены в теле гайки . Недостатком этих передач  вл етс  невозможность обеспечени  возврата шариков при изменении шага винта. Дл  обеспечени  возврата шариков при изменении шага винта трубка выполнена упругой, один из концов которой установлен в теле гайкн с возможностью перемешени  вдоль оси винта. На чертеже изображена шариковинтова  передача в разрезе, общий вид. Она имеет винт 1, гайку 2, шарики 3, расположенные в канавках винта и гайки, устройство дл  возврата шариков, выполненное в виде упругой трубки 4, один из концов 5 которой установлен в теле гайки с возмож«остью перемещени  вдоль оси винта . К гайке присоединена линейка 6 и поршень 7, поппружиненный пружиной 8, к которой присоединен указатель 9. Концы трубки 4 расположены на одной образующей .цилиндрической поверхности винта 1 и соедин ют окружные каналы дл  шариков на двух смежных витках 10 и 11. Работает шариковинтова  передача следующим образом. При вращении винта 1 относительно гайки 2 при нзменении шага винта конец 5 трубки 4 расходитс  или сходитс  в зависимости от того, увеличиваетс  шаг навивки или уменьшаетс , наход сь посто нно против окружных каналов на витках винта, и шарики 3, проходи через упругую трубкуThe invention relates to mechanical engineering and can be used in mechanisms that transform a rotational assembly into a translational one. Known ball screw, associating the screw, nut, balls {fit in the grooves of the screw and nut, a device for returning the balls, which is linear in watts. de vklatspia, placed in the body of the nut 1 |, Of the known balls of international vehicles, the closest to the invention is a ball screw drive containing a screw nut, balls located in the grooves of the screw and a nut, a device for returning the balls, made in the form of a V-shaped tube whose ends are placed in the body of the nut. The disadvantage of these gears is the impossibility of ensuring the balls return when the pitch of the screw changes. To ensure the balls return when the pitch of the screw is changed, the tube is made elastic, one of the ends of which is installed in the body of the nut with the possibility of mixing along the axis of the screw. The drawing shows a ball screw drive in section, a general view. It has a screw 1, a nut 2, balls 3 located in the grooves of the screw and nut, a device for returning the balls, made in the form of an elastic tube 4, one of the ends 5 of which is installed in the body of the nut with the possibility of movement along the axis of the screw. A ruler 6 is attached to the nut and the piston 7 is spring-loaded by a spring 8, to which the pointer 9 is attached. The ends of the tube 4 are located on one forming cylindrical surface of the screw 1 and connect the circumferential channels for the balls on two adjacent turns 10 and 11. The ball screw gear works as follows in a way. When screw 1 is rotated relative to nut 2, when the pitch of the screw is changed, the end 5 of the tube 4 diverges or converges depending on whether the winding pitch increases or decreases, being constantly against the circumferential channels on the turns of the screw, and the balls 3, pass through the elastic tube

4, поступают из окружного канала витка 1О в окружной канал витка 11. При этом указатель 9 измен ет свое положение относительно линейки 6, указыва  величину шага винта.4, come from the circumferential channel of coil 1O to the circumferential channel of coil 11. In this case, the pointer 9 changes its position relative to the ruler 6, indicating the size of the pitch of the screw.
