Abstract

The invention relates to engine design and to the production of compressor equipment. The present method allows increased meshing reliability between non-circular wheels used in heavy-duty devices, for example in synchronisers of rotary-vane engines, which are produced with oval gears that can come unmeshed at moments when they are positioned at an acute angle to one another. For this purpose, circular wheels are provided with inwardly directed grooves, the base points of which are equidistant from wheel contact points, and these are used for the movement of wheel-connecting components preventing uncoupling.

Description

СПОСОБ ПОВЫШЕНИЯ НАДЕЖНОСТИ ЗАЦЕПЛЕНИЯ METHOD FOR INCREASING THE RELIABILITY OF THE COUPLING
НЕКРУГЛЫХ КОЛЕС NON-ROUND WHEELS
Использование: Двигателестроение, производство компрессорного оборудования. Сущность изобретения: сцепленные некруглые колеса дополняются деталями, обеспечивающими сопротивление разрыву зацепления колес в направлении, перпендикулярном касательной в точке соприкосновения колес, и не препятствующих их вращению. Usage: Engine building, production of compressor equipment. The essence of the invention: interlocking non-circular wheels are supplemented with parts that provide resistance to rupture of the engagement of the wheels in a direction perpendicular to the tangent at the point of contact of the wheels, and do not impede their rotation.
Изобретение относится к машиностроению: производство двигателей, компрессоров. The invention relates to mechanical engineering: the production of engines, compressors.
Известны роторно-лопастные или роторно-поршневые двигатели, в которых для синхронизации движения лопастей используются некруглые колеса. Например, роторно-поршневой двигатель внутреннего сгорания по патент РФ 2109966. Known rotary vane or rotary piston engines in which non-circular wheels are used to synchronize the movement of the blades. For example, a rotary piston internal combustion engine according to RF patent 2109966.
При движении некруглых колес в роторно-лопастных двигателях на них воздействуют разнонаправленные нагрузки. Например, в начале взрыва горючей смеси они имеют косое зацепление и стремятся отойти друг от друга, что допускает их не круглая форма. В результате надежность зацепления некруглых колес оказывается при больших нагрузках низкой. When non-circular wheels move in rotary vane engines, multidirectional loads act on them. For example, at the beginning of the explosion of a combustible mixture, they have an oblique engagement and tend to move away from each other, which allows their non-circular shape. As a result, the reliability of the engagement of non-circular wheels is low at high loads.
Повысить надежность зацепления некруглых колес предлагается за счет добавления элементов, обеспечивающих сопротивление разрыву зацепления колес в направлении, перпендикулярном касательной в точке соприкосновения колес, и не препятствующих их вращению. Это можно сделать различными способами. It is proposed to increase the reliability of the engagement of non-circular wheels by adding elements that provide resistance to rupture of the engagement of the wheels in the direction perpendicular to the tangent at the point of contact of the wheels, and do not impede their rotation. This can be done in a variety of ways.
Например: For example:
1. (FIG. 1А, FIG. 1В) Внешняя сторона колес дополняется неподвижно закрепленной окаймляющей деталью, по периметру которой создается канавка (D для колеса А, Е для колеса В). Геометрия центральной линии канавок (F и J) совпадает с формой внешней стороны колес. Для одного из колес (В) канавка создается с внешней стороны окаймляющей детали (Е), а для другого колеса (А) с внутренней стороны окаймляющей детали (D). 1. (FIG. 1A, FIG. 1B) The outer side of the wheels is complemented by a fixed bordering piece, along the perimeter of which a groove is created (D for wheel A, E for wheel B). The geometry of the centerline of the grooves (F and J) matches the shape of the outside of the wheels. For one of the wheels (B), the groove is created on the outside of the border piece (E), and for the other wheel (A), on the inside of the border piece (D).
За счет такой формы и расположения канавок точка пересечения их центральных линий при вращении колес находится на продолжении линии зацепления колес (L). Due to this shape and location of the grooves, the point of intersection of their center lines during the rotation of the wheels is on the continuation of the line of engagement of the wheels (L).
В канавки, в точке, совпадающей с линией контакта колес, вставляется деталь круглой формы в поперечном сечении (С), свободно скользящая вдоль канавок и не дающая им раздвинуться. In the grooves, at a point coinciding with the line of contact of the wheels, a round-shaped part in cross-section (C) is inserted, freely sliding along the grooves and preventing them from moving apart.
При вращении некруглых колес, деталь (С) сохраняет свое положение относительно линии контакта колес и нейтрализует силы, отделяющие колеса от линии зацепления. Ha FIG. 1A схематично показана схема взаимодействия канавок, соединенных деталью С. When non-circular wheels rotate, part (C) maintains its position relative to the line of contact of the wheels and neutralizes the forces separating the wheels from the line of engagement. Ha FIG. 1A is a schematic diagram of the interaction of the grooves connected by part C.
На FIG. 1В Показан поперечный срез колес вдоль линии 01- 02 в зоне зацепления. FIG. 1B Shows a cross-section of the wheels along line 01-02 in the engagement zone.
2. (FIG. 2А, FIG. 2В) С внешней стороны некруглых колес (А и В) создается канавка, равноудаленная от их периметра. В канавки вставляется деталь(С), соединяющая колеса, свободно скользящая вдоль канавок и не дающая колесам потерять сцепление. 2. (FIG. 2A, FIG. 2B) A groove is created on the outside of the non-circular wheels (A and B) equidistant from their perimeter. A part (C) is inserted into the grooves, which connects the wheels, sliding freely along the grooves and preventing the wheels from losing traction.
На FIG. 2А схематично показана схема взаимодействия канавок, соединенных деталью С. FIG. 2A is a schematic diagram of the interaction of the grooves connected by part C.
На FIG. 2В Показан поперечный срез колес вдоль линии 01- 02 в зоне зацепления. FIG. 2B Shows a cross-section of the wheels along line 01-02 in the engagement zone.
3. (FIG. ЗА, FIG. ЗВ) Некруглые колеса (А и В) имеют внутреннюю полость, представляющую из себя канавку равноудаленную от зоны контакта колес и выходящую наружу в середине этой зоны. В канавки вставляется деталь (С), соединяющая колеса, свободно скользящая вдоль канавок и не дающая колесам потерять сцепление. 3. (FIG. 3A, FIG. 3B) Non-circular wheels (A and B) have an internal cavity, which is a groove equidistant from the contact area of the wheels and extending outward in the middle of this area. A part (C) is inserted into the grooves, which connects the wheels, sliding freely along the grooves and preventing the wheels from losing traction.
Точки 01 и 02 - центры вращения колес. Points 01 and 02 are the centers of rotation of the wheels.
На FIG. ЗА схематично показана схема взаимодействия канавок, соединенных деталью С. FIG. 3A schematically shows a diagram of the interaction of the grooves connected by part C.
На FIG. ЗВ Показан поперечный срез колес вдоль линии 01- 02 в зоне зацепления. FIG. ЗВ Shows a cross-section of wheels along line 01-02 in the engagement zone.
4. (FIG. 4А, FIG. 4В) Некруглые колеса (А и В) имеют внутреннюю полость, в которую помещается группа деталей C,E,D,F,J,I,K. 4. (FIG. 4A, FIG. 4B) Non-circular wheels (A and B) have an internal cavity in which a group of parts C, E, D, F, J, I, K is placed.
Детали C,E,D,F одинаковы и каждая из них состоит из двух круглых шестерен разного диаметра, сцепленные друг с другом и которые имеют общую ось вращения. Parts C, E, D, F are the same and each of them consists of two round gears of different diameters, meshed with each other and which have a common axis of rotation.
Детали J,I,K состоят из двух осей J и I, на которые помещены детали С,Е и D,F . Деталь К обеспечивает соединение осей вращения шестерен. Parts J, I, K consist of two axes J and I, on which parts C, E and D, F are placed. Detail K provides the connection of the rotation axes of the gears.
Круглые шестерни меньшего диаметра сцеплены с канавками некруглых колес, а шестерни большего диаметра попарно сцеплены между собой. Контуры канавок для сцепления с шестернями меньшего диаметра равноудалены от точки контакта внешних окружностей шестерен большего диаметра. Circular gears of a smaller diameter are meshed with the grooves of non-circular wheels, and gears of a larger diameter are interconnected in pairs. The contours of the grooves for engagement with gears of a smaller diameter are equidistant from the point of contact of the outer circles of gears of a larger diameter.
При вращении некруглых колес группа деталей C,E,D,F,J,I,K меняет свое положение, перемещаясь в вертикальном направлении, следуя за точками контакта шестерен большего диаметра. When the non-circular wheels rotate, the group of parts C, E, D, F, J, I, K changes its position, moving in the vertical direction, following the contact points of the gears of a larger diameter.
