Description

The invention relates to engine building and can be used in engines having guiding or synchronizing surfaces or mechanisms with treadmills.

The aim of the invention is to improve the performance, including the reliability and durability of a rotary engine,

Figure 1 shows the proposed engine, a cross-section; figure 2 - section aa in figure 1; on fig.Z - build a treadmill profile; figure 4 is the same option; Figures 5 and 6 show a device for compensating the wear of treadmills, longitudinal and transverse sections, respectively Fig. 7 illustrates a valve timing adjustment device; FIG. 8 shows a device for damping torsional vibrations in the output shaft; Fig. 9 shows an embodiment of the engine; figure 10 is an engine with a partial cut on the air filter and slotted sleeve.

The engine includes a housing 1 with an annular cylinder 2 and a crankcase 3, pistons A and 5, which are located in a cylinder, are double acting. The engine also has a mechanism for converting unevenly circular movement of pistons 4 and 5 into rotation of shaft 7, located in crankcase 3 and including shaft 6 with articulated rhombic mechanism 8 mounted on it, crossheads 9 and synchronizing mechanism 10 with inner 11 and outer 12 bearing washers, interconnected via a shaft 7 gears with satellites 13 and axes 14. Carter 3 is equipped with covers 15 installed on it with the possibility of synchronous rotation. The axles 14 of the satellites 13 are rigidly mounted on the covers 15. The mechanism for turning the covers can be made cam (as shown in Fig. 7) or as another known mechanism or device.

The engine has support washers, the shape of the working surfaces of which is performed on a curve with parameters

where R is the installation radius of the hinges of the middle part of the parallelogram links;

"° is the angle of deviation of the cross member from the Ler initial position;

n is a number indicating how many times the angle of rotation of the inner washer and more than an angle of 2 °;

n g is the radius of the support roller (+) for the outer washer, (-) for the inner,

In the tops of the hinged rhombic mechanism 8 there are rollers 1 b and 17 on the axes 18 hinges, installed in pairs in eccentric bushings 19, made with the possibility of rotation and fixation, for example with the help of pins 20.

Shaft 7 consists of two parts 21 and 22 mounted coaxially and connected with the help of a torsion insert 23, a friction sleeve 24 and its guide 25.

The torsion insert 23 is rigidly connected to the ends 21 and 22 of the yala 7.

The engine can have two housings 26 and 27 arranged one after the other with a rotation of 180 °, the shafts of which are connected by a splined hub 28 to a screw wheel 29. which is rigidly connected to it kinematically connected to a driving screw wheel 30, and with a driven

a mechanism, such as an oil, water or fuel pump, between the bodies

air filter 31 can also be installed.

The engine has a pair of traverses 9 connected rigidly to the ring 32, on which pistons 5 are also rigidly mounted. Traverse 9 is kinematically connected by means of a hinged rhombic mechanism 8 traverses 33, rings 32 installed in the notches 34 and rigidly connected to pistons 4. Pistons 4 and 5 have 35 gas and 36 oil seals. The organs of gas exchange include inlet 37 and outlet 38 windows, made in the housing with the necessary phase shift. The ignition organs 39 can be made in the form of spark plugs or injectors.

The engine works as follows.

The rotation of the shaft 7 causes the internal synchronizing washer 11 rigidly connected with it to rotate and, through the satellite 13, causes the external synchronizing washer 12 to rotate, along which the rollers 16 and 17 of the hinged rhombic mechanism 8 roll, which causes a periodic convergence and divergence of the pistons 4 and 5 and accordingly, the change between them a closed working volume. At their maximum approach, occurring at the ignition organs 39, the working mixture ignites and expands to the intersection of the pistons of the exhaust ports 38, through which the exhaust gases are produced when the closed working volume is reduced until they are blocked by the pistons opening the inlet ports 37, the intake and filling of the working volume with the fresh mixture takes place. Then the cycle is repeated. The multiplicity of repetition of the operating cycle per revolution of the output shaft depends on the shape of the support surfaces of the support washers (see Fig. 4).

The torque on the motor shaft 7 can be increased by increasing the number of closed working volumes, for example, by making the pistons and mechanism with a multiple increase in the number of pistons and maintaining the calculated swing angle of the traverse 9 relative to the traverse 33, as shown in FIG.

When changing the engine's timing, the timing may be far from necessary. In this case, by synchronous rotation of the cams 40, it is possible to choose the necessary phases of the displacement of the synchronizing mechanism 10 and, accordingly, the pistons relative to the inlet 37 and exhaust 38 windows.

When the treadmills are worn, the rollers 16 and 17 can be rotated on the axles 18 in the eccentric sleeves 19, which will increase the distance between the corresponding outer parts of the rollers and compensate for the gap created.
