Description

(5Jft) ЕСТЕРЕННАЯ ГИДРОМАШИНА(5Jft) WATERPROOF HYDRAULIC MACHINE

Изобретение относитс к гидравлическим машинам и может быть применено в гидросистемах тракторов, экскаваторов , сельскохоз йственных и других машин.The invention relates to hydraulic machines and can be applied in the hydraulic systems of tractors, excavators, agricultural and other machines.

Известна шестеренна гидромашина внешнего зацеплени , содержаща корпус с радиальными уплотнительными элементами, установленными с зазором по стыкуемым поверхност м, в расточках которых размещены антифрикционные полувкладыши и цапфы рабочих шестерен 1.A known gear hydromachine of external engagement, comprising a housing with radial sealing elements installed with a gap on the abutting surfaces, in the bores of which anti-friction half-liners and trunnions of working gears 1 are placed.

Недостатком известной гидромашины вл етс то, что гидродинамические силы, действующие на радиальный уплотнительный элемент, передаютс на вкладыши и выбираютс зазоры в подшипниках . Это отрицательно вли ет .на их работоспособность, так как при неблагопри тном совпадении внешних факторов вкладыш работает как ленточный тормоз, что ведет к повышенным износам или аварийному выходу изA disadvantage of the known hydraulic machine is that the hydrodynamic forces acting on the radial sealing element are transmitted to the liners and the gaps in the bearings are selected. This has a negative effect on their performance, since with an unfavorable coincidence of external factors, the liner works as a tape brake, which leads to increased wear or emergency exit from

стро гидромашины. Часть вкладыша, котора деформируетс в процессе работы радиальным уплотнительным элементом , становитс излишней и увеличивает его стоимость.stro gidromashiny. The part of the liner that is deformed during operation by the radial sealing element becomes redundant and increases its cost.

Цель изобретени - повышение надежности и долговечности.The purpose of the invention is to increase reliability and durability.

Claims

This goal is achieved by the fact that in each bore of the radial sealing elements there is one anti-friction half-liner, installed with a cantilever extension, half-thick, forming a pin on the diametrically opposite side relative to the gear pole in the gap between the joined surfaces over the entire width of the semi-liner. sealing elements. . 20 In FIG. 1 shows a hydraulic machine, a cross-section; in fig. 2 is a schematic installation of a pin in the bore of a radial sealing element. 3931 In the housing 1 of the sealing element, radial sealing elements 2 are installed with a gap along the mating surfaces 3, in each bore of which one anti-friction half-liner 5 is placed, and the pin 6 of the working gear 7. Moreover, the half-liner 5 is installed with a cantilevered extension across its width Part 8, covering the pin 6 with the diametrically opposite side relative to the pole. The gears 7 are hooked up in the gap between the mating surfaces 3 of the sealing elements

The installation of the half-liner 5, as indicated in the drawing, makes it possible to increase the area of distribution of the oils of the legs agr; ™ c :: - Page 10 Page 10 of 193 pp. Theo the development of taking special constructive measures to combat the phenomenon of bending the edges of the half-liner inward, to create an oil chamber :: "---; e ° ГГз :: Г Г „...

Creating a cantilever part 8 of the half-liner 5, washed by the flow of the working fluid, provides heat removal directly from the loaded area of the bearing a. These advantages can significantly increase the bearing capacity of the bearing, thereby increasing the reliability and durability of the hydraulic machine.
