Description

Изобретение касается гидропневмонасосов и моторов и может быть использовано в машиностроении в узлах различного назначения.The invention relates to hydropneumatic pumps and motors and can be used in mechanical engineering in units for various purposes.

Известны роторные пластинчатые машины [1], [2], содержащие одну пластину в сквозном пазу ротора, размещенного эксцентричного в некруглой полости корпуса.Known rotary plate machines [1], [2], containing one plate in the through groove of the rotor, placed eccentric in the non-circular cavity of the body.

Недостатками известных устройств как прототипа [2], так и аналога [1] являются трение скольжения пластины по пазу ротора и утечки перекачиваемой среды в зазор между пластиной и пазом ротора из зоны сжатия в зону всасывания. Без изменения конструкции эти недостатки не устранимы. В результате эффективность работы роторной пластинчатой машины существенно снижается.The disadvantages of the known devices as the prototype [2] and the analogue [1] are the sliding friction of the plate along the rotor groove and leakage of the pumped medium into the gap between the plate and the rotor groove from the compression zone to the suction zone. These disadvantages cannot be eliminated without changing the design. As a result, the efficiency of the rotary vane machine is significantly reduced.

Предлагаемое изобретение направлено на устранение этих недостатков, обеспечивая уменьшение трения, снижение утечек и, как следствие, повышение эффективности работы роторной пластинчатой машины.The proposed invention is aimed at eliminating these disadvantages, providing a decrease in friction, a decrease in leakage and, as a consequence, an increase in the efficiency of the rotary vane machine.

Указанный технический результат достигается тем, что в роторной пластинчатой машине, содержащей одну радиально подвижную пластину в сквозном пазу ротора, размещенного эксцентрично в некруглой полости корпуса, в пазу ротора выполнены полости с установленными в них телами качения, зафиксированными в сепараторах и канавки с размещенными в них упруго поджатыми уплотнениями, причем тела качения контактируют с поверхностью качения в роторе и с пластиной.The specified technical result is achieved by the fact that in a rotary lamellar machine containing one radially movable plate in the through groove of the rotor, located eccentrically in the non-circular cavity of the housing, cavities are made in the rotor groove with rolling bodies installed in them, fixed in separators and grooves with elastically compressed seals, and the rolling bodies are in contact with the rolling surface in the rotor and with the plate.

Положительный результат достигается тем, что при работе машины давление перекачиваемой среды и упруго поджатые уплотнения прижимают пластину к телам качения и при перемещении пластины они катятся по пластине и по поверхности качения в роторе, создавая легкое перемещение пластины в условиях трения качения. При этом сепараторы, размещенные в полостях ротора, фиксируют тела качения в правильном рабочем положении, совершая вместе с ними возвратно-поступательные движения, а установленные в канавках уплотнения, поджатые к пластине, препятствуют утечкам перекачиваемой среды в зону всасывания.A positive result is achieved by the fact that when the machine is operating, the pressure of the pumped medium and elastically compressed seals press the plate against the rolling elements, and when the plate moves, they roll along the plate and along the rolling surface in the rotor, creating an easy movement of the plate under rolling friction. At the same time, separators located in the rotor cavities fix the rolling elements in the correct working position, performing reciprocating movements with them, and the seals installed in the grooves, pressed against the plate, prevent the pumped medium from leaking into the suction zone.

Изобретение поясняется чертежом, где на фиг.1 изображен поперечный разрез роторной пластинчатой машины. The invention is illustrated by a drawing, where figure 1 shows a cross-section of a rotary plate machine.

Роторная пластинчатая машина содержит корпус 1, эксцентрично расположенный в нем ротор 2, в сквозном диаметральном пазу 3 которого выполнены полости 4 с размещенными в них сепараторами 5 с телами качения 6, контактирующими как с пластиной 7, так и с поверхностью качения 8. Канавки 9 с уплотнениями 10 выполнены во вставках 11, зафиксированных в роторе 2, например точками сварки 12.The rotary plate machine contains a housing 1, a rotor 2 eccentrically located in it, in the through diametrical groove 3 of which cavities 4 are made with separators 5 placed in them with rolling elements 6 in contact with both the plate 7 and the rolling surface 8. Grooves 9 with seals 10 are made in inserts 11 fixed in the rotor 2, for example by welding points 12.

На корпусе 1 расположен канал 13 впуска перекачиваемой среды и канал нагнетания 14 с клапаном 15.On the housing 1 there is a channel 13 for the inlet of the pumped medium and a discharge channel 14 with a valve 15.

Роторная пластинчатая машина работает следующим образом. При вращении ротора 2 в указанном стрелкой направлении пластина 7 в пазу 3 совершает возвратно-поступательные перемещения постоянно касаясь своими концами некруглой полости корпуса 1, а перекачиваемая среда засасывается через впускной канал 13, отсекается пластиной 7 и, при ее перемещении, сжимается и вытесняется в канал 14 через клапан 15. При этом давление перекачиваемой среды постоянно прижимает пластину 7 к телам качения 6, а тела качения, преимущественно ролики, к поверхностям качения 8, расположенным в полостях 4 ротора 2.Rotary plate machine works as follows. When the rotor 2 rotates in the direction indicated by the arrow, the plate 7 in the groove 3 makes reciprocating movements constantly touching with its ends the non-circular cavity of the housing 1, and the pumped medium is sucked in through the inlet channel 13, cut off by the plate 7 and, when it moves, is compressed and displaced into the channel 14 through the valve 15. In this case, the pressure of the pumped medium constantly presses the plate 7 against the rolling elements 6, and the rolling elements, mainly rollers, against the rolling surfaces 8 located in the cavities 4 of the rotor 2.

От перекосов и иных нежелательных смещений тела качения удерживаются сепараторами 5, перемещающимися по направляющему каналу полости 4. Поверхности качения 8 выполнены как отдельный элемент в виде термообработанной твердой пластины, закрепленной в вставках 11.The rolling bodies are kept from distortions and other undesirable displacements by separators 5 moving along the guide channel of the cavity 4. The rolling surfaces 8 are made as a separate element in the form of a heat-treated solid plate fixed in the inserts 11.

Упруго поджатые к пластине 7 уплотнения 10, размещенные в канавках 9, вставки 11, препятствуют утечке перекачиваемой среды в зазор между пластиной 7 и пазом 3 ротора 2.Seals 10 elastically pressed against the plate 7, placed in the grooves 9, the insert 11, prevent the pumped medium from leaking into the gap between the plate 7 and the groove 3 of the rotor 2.

Таким образом, предложенное устройство устраняет недостатки прототипа, обеспечивая трение качения при перемещении пластины и уплотнение зазоров между пазом ротора и пластиной, что снижает потери на трение и утечки перекачиваемой среды, повышая эффективность работы роторной пластинчатой машины.Thus, the proposed device eliminates the disadvantages of the prototype, providing rolling friction when the plate moves and sealing the gaps between the rotor groove and the plate, which reduces friction losses and leaks of the pumped medium, increasing the efficiency of the rotary plate machine.
