Description

Изобретение относитс  к машино строению и может быть использовано в устройствах дл  преобразовани вращательного движени  в поступательное ,The invention relates to mechanical engineering and can be used in devices for converting rotary motion into translational,

Целью изобретени   вл етс  повыние надежности механизма путем устранени  возможности выпадени  тел качени  при износе сепаратора.The aim of the invention is to increase the reliability of the mechanism by eliminating the possibility of rolling bodies falling out when the separator is worn.

На фиг, 1 схематически изображен шариковый винтовой механизм; на фиг. 2 - сепаратор,.Fig, 1 schematically shows a ball screw mechanism; in fig. 2 - separator ,.

Шариковый винтовой механизм содержит винт 1, взаимодействуюпо ю с ним гайку 2, сепаратор, вьшолнен-- ньш в виде звеньев 3 из ан .-ифрик- ционного материала, имеюп;их каж-- дое дугообразные скозные пазы на кон1дах5И пружинных колец Аэраз- мещенных в пазах и предназначеппьгх дл  последовательного соедимени  звеньев. Кроме того, м(5ханизм содержит тела 5 качени  (например шарики), размещенные в канавках винтаэ гайки и в сепараторе.The ball screw mechanism contains a screw 1, a nut 2 interacting with it, a separator, which is completed as links 3 of an. -Frictional material, have each arcuate slotted grooves on the end of the 5-way spring rings in grooves and destinations for sequential connection of links. In addition, m (5th frame contains 5 rolling bodies (for example, balls), placed in the grooves of the screw nuts and in the separator.

Шариковый винтовой механизм работает следуюш им образом,The ball screw mechanism works in the following way,

При винта 1 гайка 2 совершает поступательное перемещение . Сепаратор удерживает шарикиWhen the screw 1, the nut 2 makes a translational movement. The separator holds the balls

, от выпадани . По мере износа звеньев 3 из антифрикционного материала они автоматически прижимаютс  к телам качени  5 пружинным кольцом 4,, предотвраща  их выпадание, что по1Q вьшает надежность механизма в целом .from falling out. As the anti-friction material links 3 wear out, they are automatically pressed against the rolling bodies 5 by a spring ring 4, preventing them from falling out, which means that the overall mechanism is more reliable.
