Abstract

Изобретение относитс  к машиностроению и используетс  в устройствах дл  преобразовани  движени . Целью изобретени   вл етс  повышение надежности путем улучшени  установки шариков в гнезда гибкого сепаратора. Положительный эффект обеспечиваетс  выполнением сепаратора 3 в виде тонкостенной трубки, наружный диаметр которой не превышает диаметр шариков 4, а гнезда образованы прорез ми вдоль оси трубки. При передаче нагрузки шарики 4, установленные в гнездах, наход тс  в контакте с винтовыми нарезками винта 1 и гайки 2. В рабочей зоне шарики 4 вращаютс  между винтом 1 и гайкой 2, захватыва  консистентную смазку из полости сепаратора 3. 4 ил.The invention relates to mechanical engineering and is used in devices for converting motion. The aim of the invention is to increase reliability by improving the installation of balls in the sockets of the flexible separator. A positive effect is provided by making the separator 3 in the form of a thin-walled tube, the outer diameter of which does not exceed the diameter of the balls 4, and the slots are formed by slots along the axis of the tube. When transferring the load, the balls 4 installed in the sockets are in contact with the screw threads of the screw 1 and the nut 2. In the working area the balls 4 rotate between the screw 1 and the nut 2, grabbing grease from the cavity of the separator 3. 4 Il.
