Изобретение относитс  к машиностроению и может быть использовано в механизмах дл  преобразовани  вращательного движени  в поступательное.The invention relates to mechanical engineering and can be used in mechanisms for converting rotational motion into translational.

Цель изобретени  - повышение кинематической точности при любом направлении приложени  нагрузки.The purpose of the invention is to increase the kinematic accuracy in any direction of application of the load.

На фиг.1 изображен ролик передачи винт-гайка, разрез; на фиг.2 - часть планетарной передачи винт-гайка на фиг.З - то же, непланетарной передачи.Figure 1 shows the transfer roller screw-nut section; figure 2 - part of the planetary gear screw-nut fig.Z - the same non-planetary gear.

Ролик 1 включает ось 2 с нарезкой 3 в средней части,диаметр которой равен диаметру частей 4, установленных по обе стороны от нарезки 3 соосно друг другу, упругие элементы 5, установленные по наружным торцам частей 4, дополнительные упруThe roller 1 includes an axis 2 with cutting 3 in the middle part, the diameter of which is equal to the diameter of the parts 4 installed on both sides of the cutting 3 coaxially with each other, elastic elements 5 installed along the outer ends of the parts 4, additional elastic

гие элементы 6, взаимодействующие с торцами нарезки 3 и частей 4. Все элементы ролика 1 ст нуты гайками 7, расположенными по концам оси 2.All these elements of roller 1 are fastened with nuts 7 located at the ends of axis 2.

В планетарной роликовинтовой пере даче ролики 1 установлены в.сепараторе 8 и наход тс  в зацеплении с резьбой винта 9 и гайкой 10.In the planetary roller screw transmission, the rollers 1 are mounted in the separator 8 and are engaged with the screw thread 9 and the nut 10.

В непланетарной роликовинтовойIn non-planetary roller screw

передаче гайка выполнена в виде кор- пуса 11 с установленными в нем роликами 1 в опорах 12.the transfer nut is made in the form of a housing 11 with rollers 1 installed in it in supports 12.

Работа передачи винт-гайка происходит следующим образом.Work transfer screw-nut is as follows.

Ролики I ст гиваютс  гайками 7 таким образом, чтобы упругие элементы 5 и 6 были сжаты и нарезка 3 и на част х 4 ролика 1 входила в соответствующие пазы на резьбовой нарезке винта 9 и гайки 10 дл  выбора зазоров в винтовом зацеплении.The rollers I are fastened with nuts 7 so that the elastic elements 5 and 6 are compressed and cutting 3 and on parts 4 of roller 1 fit into the corresponding grooves on the threaded cutting of screw 9 and nut 10 to select the gaps in the screw engagement.

При этом сжатые упругие элементы 5 и 6 обеспечивают компенсацию погрешности шага резьбы винта и гайки .In this case, the compressed elastic elements 5 and 6 provide compensation for the error of the thread pitch of the screw and the nut.
