Изобретение относитс  к области гидромашиностроени . Известна шестеренна  гидромашина, содержаща  размещенные в корпусе шестерни, установленные в подцшпника скольжени , и шайбы, причем между шайбами и подшипниками размещено устройство дл  компенсации торцовых зазоров, соединенное с полостью высо кого давлени  и выполненное в виде эластичной манжеты 11. Недостатком этой шестеренной гидр машины  вл етс  увеличенна  зона высокого давлени  и мала  .величина регулировани  компенсёщии торцовых зазоров . Целью изобретени   вл етс  повышение наде жности в работе и КПД шестеренной гидромашины. Это достигаетс  тем, что в предложеннс гидромашине полые эластичные манжеты выполнены составными из двух частей Г- и П-образного сечени  На фиг. схематически изображена предложенна  гидромашина, продольный разрез; на фиг.2 - то же, поперечный разрез; на.фцг.З - узел I на фиг. The invention relates to the field of hydraulic engineering. A known gear hydromachine, containing gears placed in the housing, installed in the slip spline, and washers, and between the washers and bearings there is a device for compensation of end gaps, connected to the high pressure cavity and made in the form of an elastic cuff 11. The disadvantage of this gear hydr machine is There is an increased high pressure zone and a small amount of adjustment of the compensating end gaps. The aim of the invention is to increase the operational reliability and efficiency of the gear hydraulic machine. This is achieved by the fact that, in the hydromachine's proposed hollow elastic cuffs, are made up of two-part G and U-shaped sections. In FIG. schematically shows the proposed hydraulic machine, a longitudinal section; figure 2 is the same cross section; Fig. 3 — node I in FIG. 2. Шестеренный насос имеет корпус 1, в котором размещены шестерни 2, уста новлениые в подшипниках скольжени  3 По торцам шестерен 2 установлены компенсационные пластины 4, а в выемках подшипников сксхльжени  3 установлены эластичные манжеты Б и 6 Пи Г-образного сечени , в углах которых вмонтированы вставки 7 из материала с более высокими механическими свойствами, чем эластичные манжеты 5 и 6. Пластина 8 уплотнена резиновым кольцом 9 и прижата к подшипнику скольжени  3 крышкой 10., Жидкость под давлением подаетс  в полость а из области высокого давлени  через отверстие 11 и разжимает эластичные манжеты 5 и 6, которые воздействуют на компенсационные пластины 4, поджима  их к тсфцам шестерен 2, выбира  торцовые заэсчры. Эластична  манжета 5 прижимаетс  к корпусу 1 насоса, ограничива  зону распространени  высокого давлени . При износе компенсащионные пластины 4 поджимаютс  к торцам шестерен 2 за счет деформации эластичных манжет 5 и 6. Благодар  наличию раздвижных эластичных манжет повышаетс  надежность в работе и КПД гидромашины. Формула изобретени  Шестеренна  гидромашима, содержаща  размещенные в корпусе шестерни. установленные в полшипниках скольжени , и шайбы, причем между шайбами и подимпниками размещены полые эластичные .манжеты, соединенные с полостью высокого давлени , отличающа  с   тем, что, с целью повы11 ени  надежности в работе и КПД, манжеты б выполнены составными, например, из двух частей Г- и П-образного сечени . Источники информации, прин тые во внимание при экспертизе 1, Авторское свидетельство № 383880,кл. F 04 С 1/04, 1971.2. The gear pump has a housing 1, in which gears 2 are placed, installed in sliding bearings 3 The compensation plates 4 are installed at the ends of gears 2, and elastic cuffs B and 6 of PI of the L-shaped section are installed in the recesses of the slip bearings 3, in the corners of which the inserts 7 are made of a material with higher mechanical properties than elastic cuffs 5 and 6. The plate 8 is sealed with a rubber ring 9 and pressed against the sliding bearing 3 by a cover 10. Pressure fluid is fed into the cavity from a high area and yes through the hole 11 and expands the elastic cuffs 5 and 6, which act on the compensation plates 4, pressing them against the pinions of the gears 2, choosing the end faces of the gears. The elastic cuff 5 presses against the pump body 1, limiting the high pressure distribution area. When worn, the compensating plates 4 are pressed against the ends of the gears 2 due to the deformation of the elastic cuffs 5 and 6. Due to the sliding elastic cuffs, the reliability and the efficiency of the hydraulic machine are improved. Claims of Gear Gear Hydromachine, comprising gear mounted in housing. installed in sliding bearings, and washers, with hollow elastic cuffs placed between the washers and sub-supports, connected to the high-pressure cavity, characterized in that, to improve reliability in operation and efficiency, the cuffs B are made of composite, for example, two parts of G- and U-shaped section.
