Abstract

In a rotary-piston internal-combustion engine in which two sets of pistons rotate about a common axis while in sealing engagement with a cylindrical casing wall, and the two sets are connected so that the pistons of one set rotate at uniform speed and those of the other set rotate at cyclically varying speed to expand and contract combustion chambers circumferentially bounded by the pistons, the uniformly rotating pistons are fixedly fastened to the radial end walls of the casing, and motion is transmitted between the two sets by crankshafts journaled in a gear carrier fixedly fastened to one of the end walls and oscillating a mounting sleeve for the pistons of the other set. The crankshafts are rotated by respective gears meshing with a ring gear fastened to the normally stationary cylindrical casing wall.

В неподвижной корпусе 1 двигател  выполнена кольцева  рабоча  камера 2, ограниченна  с торцев боковыми крышками 3 и 4. В рабочей камере 2 размещены (4«г. 2) лопастные рабочие органы: основные 5, кинематически .св занные с выходным валсм 6 посто нной угловой скорости, и вспомогательные 7/ кинематически св занные с валом 8 механизма периодического изменени  угловс скорости. Механизм периодического изменени  угловой скорости размещен в кожухе 9 и выполнен в виде крИвошипно-шатунной передачи 10, снабженной малой шестерней 11, о6катыва1ачейх;  по неподвижной, шестерне 12, установленной в корпусе 1. . Вспомогательные рабочие органы 7 выполнены с ВТУЛКОЙ 13, установленнсй концентрично с валом 8 механизма периодического изменени  угловой скорости и св занной с ним при помооц шпиц 14 на стороне, противоположной упом нутому механизму, причем вспомогательные рабочие органы 7 закреплены на втулке 13 при помощи винтов 15,,голойки которых расположены на внутренней поверхности втулки 13.: Кожух 9 механизма периодического изменени  угловой скорости выполнен с возможностью вращени  и св зан с одной стороны непосредственно с основными рабочими органами 5, а с,другой с выходным ВсШОМ 6 .The invention relates to internal engines with uneven movement of workers (in the annular working chamber). Internal engines are known with uneven movement of the working bodies, containing fixed axial valves with an annular working chamber and vane working saganas: basic, kinematically connected to the output shaft. angularity, and auxiliary, kinematically associated with the shaft of the mechanism of periodic changes in angular velocity, placed in the casing and made in the form of a crank-rod A gear equipped with a small gear running on a stationary gear installed in the X13 gear. The disadvantage of this engine is significant inertial loads on the elements of the mechanism for the periodic change of the angular distortion, reduced engine service. increase in service life. The goal is achieved by auxiliary working bodies with a sleeve mounted concentrically with the shaft cally varying angular velocity and bonded to the shaft by means of a slot formed on a side opposite to a cover mechanism is rotatable and is bonded to one side neposre dstvonno rabochish with the main bodies and on the other stschrony - with the output shaft. Auxiliary workers argaal for KpeafieifiJ on the sleeve with screws, the heads of which are located on the inner surface of the sleeve. FIG. 1 shows the proposed engine, a longitudinal section; in fig. 2 - the same, cross-section along the working chamber; in fig. 3 - the same, cross-section: 1st section along the casing of the mechanism of periodic change in angular velocity. RosAi; in fig. 4 is a schematic of the attachment of auxiliary working sargans on a sleeve, option In the fixed case 1 of the engine there is an annular working chamber 2, bounded from the ends by side covers 3 and 4. In the working chamber 2 there are bladed working bodies: main 5, kinematically connected to the output shaft 6 constant angular speeds, and auxiliary 7 / kinematically associated with the shaft 8 of the mechanism for periodically varying angles of speed. The mechanism for the periodic variation of the angular velocity is located in the casing 9 and is designed as a red crank gear 10, equipped with a small gear 11, about 6 rolls; on the fixed gear 12 mounted in the housing 1.. The auxiliary working bodies 7 are made with a SLEEVE 13, mounted concentrically with the shaft 8 of the mechanism for a periodic change in angular velocity and associated with the spitz 14 on the side opposite to the said mechanism, with the auxiliary working bodies 7 secured to the sleeve 13 with screws 15, whose naked covers are located on the inner surface of sleeve 13.: The casing 9 of the mechanism for the periodic change in angular velocity is rotatably connected to one side directly with the main workers. Rangs 5, and with, another with weekend VSHOM 6.

При вргицении выходного вала 6 с посто нной угловой скоростью вспомогательные рабочие органы 7, именхцие переменную угловую скорость вращени , периодически сближаютс  с основными рабочими органами 5/ обеспечива  изменение заключенных между ними рабочих объемов и протекание темодинамических процессов.When the output shaft 6 is operated at a constant angular velocity, the auxiliary working bodies 7, i.e. variable angular rotational speed, periodically draw closer to the main working bodies 5 / ensuring the change of the working volumes between them and the flow of the thermodynamic processes.

Наличие втулки 13, несущей вспомогательные рабочие органы 7 и св занной при помощи шлиц 14 с валом 8 механизма периодического изменени  угловой скорости, обеспечивает выравнивание 1агрузок на элементах механизма периодического изменени  угловой скорости и приводит к увеличению их срока службы.The presence of the sleeve 13, carrying the auxiliary working bodies 7 and connected with the aid of the slot 14 to the shaft 8 of the mechanism for the periodic change in angular velocity, ensures the alignment of loads on the elements of the mechanism for the periodic change in the angular velocity and leads to an increase in their service life.
