(54) ДВУСТОРОННЯЯ ОСЕВАЯ ОПОРА(54) BILATERAL AXIAL SUPPORT

Изобретение относитс к мапганрстроению и может быть применено- в насосах, турбинах, компрессорах, при работе которых возникают значительные по величине осевые силы.The invention relates to a machine construction and can be applied in pumps, turbines, compressors, during the operation of which considerable axial forces arise.

.. Известна двусторонн осева опора , содержаща корпус, смонтированную на вёшу п ту в виде, ступенчатого диска, несущие камеры, расположенные по обе стороны диска, кгшал отвода рабочей жидкости, соединенный с несущими камерами через выходные щелевые дроссели, образованные торцовыми повэрхност ми.. периферийной части п ты и корпуса, а также канал и камеру подвода рабочей жидкости « входные щелевые дроссели СI... A two-sided axial support is known, comprising a body mounted on a pile in a form, a stepped disk, carrier chambers located on both sides of the disk, the discharge of working fluid connected to the load-bearing chambers through end slits formed by face surfaces. the peripheral part of the ny and the body, as well as the channel and the chamber for supplying the working fluid “input slit throttles CI.

Недостатком известной конструкции вл етс то, что ав орегулирование за счет наружных торцовых дросселей предполагает достаточно большой расход жидкости, а кавитаци приводит к разрушению элементов конструкции.A disadvantage of the known construction is that the regulation by means of external end chokes implies a sufficiently large flow rate, and cavitation leads to the destruction of the structural elements.

Цель изобретени - повышение несущей способности, уменьшение расхода жидкости через п ту, а также упрощение конструкции.Поставленна цель достигаетс тем, что в двусторонней .осевой опоре, содержащей корпус, смонтированнуюThe purpose of the invention is to increase the carrying capacity, reduce the flow of fluid through the heel, as well as simplify the design. The goal is achieved by the fact that in a double-sided axle support comprising a housing mounted

Claims

In the drawing, a double-sided 30th axial bearing is shown. The double-sided axle support contained a housing 1 mounted on a ptu 2 shaft in the form of a stepped disc. In the body of pt 2, a chamber –3 is made under the working fluid. On both sides of the disk there are carrier chambers 4 connected to the channel 5 for discharging the working fluid through the output slit throttles 6, formed by the end surfaces of the peripheral part of the terminal 2 and the housing 1, as well as with the channel 7 for supplying the working fluid and the camera 3 for supplying through the slit inlets throttles 8. In channel 7 and supply chamber 3, valve 9 is installed in the form of a sleeve having radial holes. 10 dl. the passage of the working fluid, on the outer surface of which is mounted the end face 11, forming with their ends qo the walls of the supply chamber 3 input throttles 8. The valve 9 can be mounted in the housing 1 with the possibility of axial movement. The support works as follows. the hole in the sleeve 9 in the camera 3 supply, where, depending on the size of the input slit throttles 8 enters. into the supporting chambers 4 and further through the output slit throttles between the sealing rings 12 and the fifth 2 - into the channel 5 of the outlet. The throttles 8 regulate the pressure in the chambers 4, causing a force opposing the bias of the heel. In the drawing, one of the rings 11 is shown fixed on the sleeve 9, and the entire valve is movable in the axial direction and pressed by the fluid pressure to the end surface of the housing 1.. In another embodiment, the valve 9 can be fixed in the chamber motionless, and the ring 11 is seated on the barrel with the possibility of axial movement. The invention makes it possible to reduce the flow rate and simplify the design by introducing auto-adjustment on as small diameters as possible. This increases the reliability following small linear speeds and increases the bearing capacity of the support. Claim 1. Bilateral axial support, comprising a housing mounted on a shaft in the form of a stepped disk, carrier chambers located on both sides of the disk, a channel for discharging working fluid connected to the carrier chambers through the output slotted throttles formed by the end surfaces of the peripheral parts of the pen and housing, as well as the channel and the chamber for supplying the working fluid and the inlet slit throttles, characterized in that, in order to increase the carrying capacity, reduce the consumption of the working fluid and simplify the design The chamber for supplying the working fluid is made in the body of the rod, and the support is provided with a valve mounted in the housing and installed in the channel and a valve for supplying the working fluid in the form of a sleeve having radial holes for the passage of the working fluid and mounted on its outer surface of the rings forming their ends from the wallMy cameras supplying input slit throttles.

2. A support according to Clause 1, .o tl and h and y and a sh with the fact that the valve is mounted in the housing with the possibility of axial movement, 3. The support according to Clause 1, characterized in that the valve rings are mounted on the sleeve with the possibility of axial movement. . .
