Abstract

FIELD: mechanical engineering. SUBSTANCE: rotor machine has housing with a cylindrical bore and passageways for supplying and discharging fluid, stop ring axially alined in the housing, rotor with diametrical profiled grooves that is mounted inside the housing eccentrically, and rods received in the grooves. The ends of the rods are provided with separating plates that can move in radial direction inside the rotor grooves and define working chamber in the stator ring. Both of the rod ends are rigidly secured to the adjacent plates. The inner surface of the stator ring is a polyhedron. The polyhedron is coaxial to the outer surface of the stator ring. The number of sides of the polyhedron is equal to the number of the plates. The length of the sides is defined by a relationship available in the invention description. The contact surface of the radial end of the plate is perpendicular to the rod axis. The width of the contact surface of the radial end of the plate is greater than the thickness of the plate. A longitudinal groove is made in the central part of each contact surface of the plate. The groove receives a flexible sealing member. The member is a plate bent in the cross-section, e.g., as an arc of a circumference. The rotor and stator ring are kinematically interconnected through a gear with 1:1 gear ration. EFFECT: enhanced longevity.

Изобретение относится к области машиностроения и может быть использовано в насосо- и двигателестроении. Цель изобретения - устранение шума при работе роторной машины, локальных износов статорного кольца, снижение утечек рабочей среды и уменьшение потерь на трение. Этот технический результат достигается в роторной машине, содержащей корпус с цилиндрической расточкой и каналами подвода и отвода рабочей среды, соосно установленное в корпусе статорное кольцо, эксцентрично установленный в корпусе ротор с диаметральными профилированными пазами и размещенными в них стержнями с разделительными пластинами на концах, имеющими возможность радиального перемещения в пазах ротора и образования в статарном кольце рабочих камер. Новым в роторной машине является то, что оба конца каждого стержня жестко соединены с прилегающими пластинами, а внутренняя поверхность статорного кольца выполнена в виде соосного с его внешней поверхностью многогранника с числом рабочих граней, равным количеству пластин, при этом длина граней выполнена с условием L > 2 Е + Т, где L - длина рабочей грани многогранника; Е - эксцентриситет установки ротора относительно статорного кольца: Т - ширина контактной поверхности радиального конца пластины. Контактная поверхность радиального конца пластины выполнена под прямым углом к оси стержня. Ширина контактной поверхности радиального конца пластины больше толщины пластины. В центральной части каждой контактной поверхности пластины выполнен продольный паз, в который установлен упругий уплотнительный элемент, имеющий форму пластины, изогнутой в поперечном сечении, например, по дуге окружности. Ротор и статорное кольцо кинематически соединены зубчатой передачей с передаточным отношением 1 : 1.The invention relates to the field of mechanical engineering and can be used in pump and engine building. The purpose of the invention is the elimination of noise during operation of the rotor machine, local wear of the stator ring, reducing leakage of the working environment and reducing friction losses. This technical result is achieved in a rotary machine, comprising a housing with a cylindrical bore and channels for supplying and discharging a working medium, a stator ring coaxially mounted in the housing, a rotor eccentrically mounted in the housing with diametrically profiled grooves and rods placed in them with dividing plates at the ends, which have the ability to radial movement in the grooves of the rotor and the formation in the stationary ring of the working chambers. What is new in the rotary machine is that both ends of each rod are rigidly connected to adjacent plates, and the inner surface of the stator ring is made in the form of a polyhedron coaxial with its outer surface with the number of working faces equal to the number of plates, while the length of the faces is fulfilled with the condition L> 2 E + T, where L is the length of the working face of the polyhedron; E is the eccentricity of the rotor installation relative to the stator ring: T is the width of the contact surface of the radial end of the plate. The contact surface of the radial end of the plate is made at right angles to the axis of the rod. The width of the contact surface of the radial end of the plate is greater than the thickness of the plate. A longitudinal groove is made in the central part of each contact surface of the plate, into which an elastic sealing element is installed, having the shape of a plate bent in cross section, for example, along a circular arc. The rotor and stator ring are kinematically connected by a gear transmission with a gear ratio of 1: 1.
