Изобретение относитс к машиностроению , а именно к устройствам дл передачи поступательного движени в вакуум.The invention relates to mechanical engineering, namely to devices for transmitting translational motion into a vacuum.

Известен бессальниковый привод дл осевого перемещени шпиндел в запорной и регулирующей трубопроводной аппаратуре , содержащий корпус, установленный в нем эксцетриковый вал, сильфов , наклонное кольцо с проточками (гайку ), св занное с одним концом сильфона , другой конец которого св зан с корпусом l1 ,A shaftless drive for axial movement of the spindle in the shut-off and regulating pipeline equipment is known, comprising a housing, an eccentric shaft mounted therein, bellows, an inclined ring with grooves (nut) connected to one end of the bellows, the other end of which is connected to the housing l1,

Однако сильфон привода посто нно находитс под воздействием скручивающих усилий, снижает надежность его конструкции .However, the drive bellows is constantly under the influence of twisting forces, reducing the reliability of its design.

Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс устройство дл передачи поступательного дв1гжени в вакуум , содержащее корпус с неправл ющими , установленные в нем эксцентриковыйThe closest in technical essence and the achieved result to the invention is a device for transmitting two-way transmission to vacuum, comprising a housing with non-correcting, eccentric

вал и взаимодействующий с ним ходовой винт, опоры качени , взаимодействующую с винтом гайку, соединенные ооними концами с корпусом сильфоны L2 .the shaft and the drive screw interacting with it, the rolling bearings, the nut interacting with the screw, connected by ends with the bellows L2.

Известное устройство характеризуетс невысокой точностью передаваемого движени вследствие малой стабильности перемещени ;Исполнительного звена.The known device is characterized by a low accuracy of the transmitted movement due to the low stability of the movement; Executive link.

Цель изобретени - повышение точности передаваемого движени .The purpose of the invention is to improve the accuracy of the transmitted movement.

Claims

The device for transmitting the forward motion into vacuum comprises a housing 1 with guides, an eccentric shaft 3 installed therein and a lead screw 4 interconnecting with it, bearings 5 and 6 of rolling, a nut 7 interacting with screw 4, connected at one end with the housing 1 sylphrons 8 and 9, the Eccentric Shaft 3 is installed in the running wheel 4 and interacts with it by means of the supports 5 and 6 of rolling. The bellows 8 and 9 are connected to the lead screw with the other ends. The nut 7 is made in the form of a housing 10 connected to it by bearings 11 and 12 of the sleeve 13 and a set of elastic rings 14, 15 and 16. Elastic ring 14 is connected case 10 nuts 7, and the rings 15 and 16 are installed in the sleeve 13, the Eccentric shaft 3 is installed in the housing 1 on the supports 1.7 and 18 rolling. The device works as follows. On the eccentric shaft 3, rotation is transmitted on the drive axis (not shown), which is converted into plane-parallel oscillations of the lead screw 4. Flat-plane oscillations; One screw 4 is converted into translational movement of the housing 10 of the nut 7, 1 which slides along the guides 2 of the case I. The proposed device has a high reliability of operation, high accuracy of the parameters of the transmitted engine (04) and can work in services () B1 (under significant loads. Apparatus of the invention One end connected to the body is a bellows, characterized in that, in order to ensure the accuracy of the transmitted movement, the eccentric shaft is installed in the lead screw and interacts with it through bearings, the syphals are connected with the other ends to the lead screw, and the nut is made in the form of a Kopnj ca associated with the bearings of the sleeve and the set of elastic rings, one of which is associated with the body of the nut and the others mounted in the sleeve.
