Изобретение относитс к области машиностроени и может быть использовано дл перемещени различных жидкостейThe invention relates to the field of engineering and can be used to move various liquids.

Известна шестеренна гидромашина, содержаиш статор в виде шестерни внутреннего зацепле1щ , св занной через сателлиты с наружными зубь ми ротора, установленного на врагцаклцемс эксцентрике l.A known gear hydromachine containing a stator in the form of an internal gear gear that is connected via the satellites to the outer teeth of the rotor mounted on the eccentric eccentric l.

Однако дл обеспечени работы машины при прохождении нейтральных положений ротора требуетс дополнительный статор с системой гидравлического управлени , что в целом делает устройство ненадежным.However, an additional stator with a hydraulic control system is required to ensure the operation of the machine during the passage of neutral rotor positions, which generally makes the device unreliable.

Целью изобретени вл етс повьпие- ние надежности гидромашины.The aim of the invention is to improve the reliability of the hydraulic machine.

Это достигаетс тем, что в известной шестеренной гидромашине ротор вы- подмен полым и на его внутренней поверхности выполнены зубь , а на эксцен трике допошитегьно установлена жестко св занна со статором шестерн наружного зацеплени , взаимодействующа сThis is achieved by the fact that, in a known gear hydromachine, the rotor is replaced by a hollow one and teeth are made on its inner surface, and an eccentric gear of external gearing is connected to the eccentric

зубь ми на внутренней поверхности ротора через паразитную шестеррпо.teeth on the inner surface of the rotor through the parasitic gear.

На фиг. 1 представлена шестеренна гидромашина, поперечный разрез; на фиг. 2 - то же, продольный разрез.FIG. 1 shows a gear hydromachine, a transverse section; in fig. 2 - the same, longitudinal section.

Шестеренна гидромашина состоит из статора 1, выполненного в виде шестерни внутреннего зацеплени с отверсти ми 2 и 3 подвода-отвода рабочей жидкости . Ротор 4 установлен на вращающемс эксцентрике 5, снабжен наружными зубь ми, которыми он через сателлиты 6 взаимодействует со статором 1, и зубь ми 7 на внутренней поверхности. Шестерн наружного зацеплени 8, установленна на эксцентрике и жестко св занна со статором, взаимодействует с аубь ми 7 ротора 4 через паразитную шестерню 9. A gear hydromachine consists of a stator 1 made in the form of an internal gear with holes 2 and 3 of the supply and discharge of the working fluid. The rotor 4 is mounted on a rotating eccentric 5, provided with external teeth, with which it interacts with stator 1 through satellites 6, and teeth 7 on the inner surface. The external gear 8, mounted on the eccentric and rigidly connected with the stator, interacts with the shaft 7 of the rotor 4 through the parasitic gear 9.

Claims

The device works as follows. When the eccentric 5 rotates, the rotor 4 with its teeth locks the satellites 6, which roll in such a way that) ". The centers describe a circle with an angular velocity equal to half the angular velocity of the eccentric, and they are on the line passing through the axis of rotation of the eccentric 5. The angular velocity of the rotor 4 required for this is provided by the interaction of the teeth on its inner surface with the external gear 8 through the parasitic gear 9, the cavity of the stator 1, due to the rotor and the satellite, is divided into two working chambers of variable volume. The chamber, whose volume is now increasing, communicates with the work lead hole flow, and the other, the volume of which is reduced, communicated with, by injection. Such a device gear hydraulic machines increases its reliability. 9 Claims of the invention A gear wheel hydraulic machine comprising a stator in the form of an internal gearing gear connected through the satellites to the outer teeth of the rotor mounted on a rotating eccentric, is so tied to the fact that in order to increase the reliability of the hydraulic machine An internal surface is made of a tooth, and on the eccentric there is an additional external gear wheel rigidly connected to the stator, which interacts with the teeth on the internal surface of the rotor via a parasitic gear.
