Description

Изобретение относитс  к области машиностроени  и может использоватьс  в высокоточных илшндельных узлах станков.The invention relates to the field of mechanical engineering and can be used in high-precision and single-machine tool assemblies.

Известна гидростатическа  опора, содержаща  йал с расположенными на нем несуидими карманами , приемные камеры, сообидающиес  с последними посредством соеди1штельных каналов и винтовых канавок, вьшолненных на наружной поверхности втулки, размещенной в нендральном отверстии вала, а также камеру нодвода рабочей жидкости.A hydrostatic support is known, containing a yal with nonsuid pockets located on it, receiving chambers communicating with the latter by means of connecting ducts and helical grooves mounted on the outer surface of a sleeve placed in the nondral shaft opening, as well as the chamber of the working fluid supply.

Целью изобретени   вл етс  снижение тепловьщелений и осевых габаритов опоры нри одновременном увеличеш1и ее жесткости и улучшежде технологачности.The aim of the invention is to reduce the thermal fission and axial dimensions of the support while simultaneously increasing its rigidity and improving the processability.

Это достигаетс  тем, что в предлагаемой опоре приемные камеры размещены во втулке непосредственно у каждой из винтовых канавок, а камера подвода размещена в теле вала, при этом втулка установлена с возможностью радиального перемещени , зафиксирована от проворота и снабжена обоймой с отверсти ми в месте подхода к ней соединительных каналов.This is achieved by the fact that in the proposed support, the receiving chambers are located in the sleeve directly at each of the helical grooves, and the supply chamber is located in the shaft body, while the sleeve is installed with the possibility of radial movement, fixed from rotation and equipped with a clip with holes in place her connecting channels.

На фиг. 1 показана предлагаема  опора Б осевом разрезе; на фиг. 2 - развертка по наружному диаметру втулки; на фиг. 3 - разрез по А-А на фиг. 1.FIG. 1 shows the proposed support B axial section; in fig. 2 - sweep over the outer diameter of the sleeve; in fig. 3 is a section along A-A in FIG. one.

Опора содержит корпус 1, внутри которого помещен вал 2 с расположенными на нем несущими карманами 3.The support includes a housing 1 inside of which a shaft 2 is placed with bearing pockets 3 arranged on it.

В центрштьном отверстии вала 2 установлена втулка 4 с возможностью радиального перемеще1ШЯ , на наружной поверхности которой вьшолнены нриелппэЮ камеры 5 и  ннтовые канавки 6.In the center hole of the shaft 2, there is installed a sleeve 4 with the possibility of radial displacement, on the outer surface of which cameras 5 and the new grooves 6 are made.

Винтовые канавки 6 закрыты обоймой 7 с отверсти лш 8 в месте подхода ко втулке 4 соедннительньк каналов 9, выход щих в несущие карманы 3.The helical grooves 6 are closed by the yoke 7 with the aperture 8 8 in place of the approach to the hub 4 of the connecting ducts 9 which extend into the carrying pockets 3.

Втулка 4 снабжена на торцовой поверхности щтифтами Ш, вход щикш в соответствующие пазы вала 2 и фиксирующими втулку от проворота.The sleeve 4 is provided on the end surface of the studs W, the entrance slitsh in the corresponding grooves of the shaft 2 and the locking sleeve from rotation.

Втулка может быть также соединена с телом вала через габкие мембранные элементы.The sleeve can also be connected to the shaft body through gabkie membrane elements.

Камера 11 подвода рабочей жидкости размещена в теле вала 2 и отделена от приемных камер кольцевой щелью 12,  вл ющейс  входным дрос оелем опоры.The chamber 11 for supplying the working fluid is placed in the body of the shaft 2 and is separated from the receiving chambers by an annular gap 12, which is the inlet throttle of the support.
