Description

 . ,

The invention relates to mechanical engineering, in particular, to an engine-building, namely to volumetric rotary machines.

The purpose of the invention is to increase the efficiency of the volumetric rotary machine by adjusting the displacement depending on the load.

The volumetric rotor machine comprises a cylindrical body 1, fitted with guides 2, face kryshki 3, a cylindrical rotor 4 mounted in the center of the body 1 on the driving 5 and the driven 6 shaft, the rotor

4 is equipped with blades 7, hinged in it. sector cavity 8, and is rigidly connected to the drive shaft 5, and the blades 7 are connected with the driven shaft 6 by connecting rods 9 and cranks 10,

The drive shaft 5 is installed inside the driven 6 shaft coaxial with it. Leading 5 and driven 6 shafts are connected by a mechanism for adjusting the working volume of the rotor cavities, operating according to the principle of converting the uniform rotation of the driving shaft 5 into uneven rotation of the driven shaft 6. The mechanism for controlling the working volume of the rotor cavities consists of a ring 11 with a protrusion 12 installed in the housing part 1 coaxially to shafts 5 and 6 with the possibility of movement in the direction of 2 perpendicular to the axis of the shafts

5 and 6, two cranks 13 and 14 and two connecting rods 15 and 16, Crank 13 and connecting rod 15 connect the drive shaft 5 with the protrusion 12 of the ring 11, and the crank 14 and connecting rod 16 connect the driven shaft

6 with the same protrusion 12, and the cranks are rigidly fixed in the opposite direction. Cranks 13 and

14 in the absence of eccentricity in the mechanism for adjusting the working volume of the rotor cavities are installed in the opposite direction relative to each other and are arranged parallel to the cranks IO, Cranks 9 blades 7 when the latter

55731 in the upper dead point are located parallel to the cranks 13 and 14.

The design described above relates to a machine with two working cavities located diametrically in the rotor.

When making a machine with four working cavities located. | Q at an angle relative to each other, the number of mechanisms for adjusting the working volume of the cavities of the rotor doubles, and the cranks 13 of the heads; their shafts 5 o6 oitix of mechanisms are perpendicular to each other

the surface of 7 rings 11 is common to them, and placed. they are in the same housing,

The case is made inlet 18. and an outlet 19 of the window and the cavity 20 of the cooling system.

The drive shaft 5 and the rotor 4 are connected to the output shaft 21, radial 22 and front 23 seals are installed in the rotor 4, and seals 24 are installed in the blades x 7

When the machine is manufactured as an internal combustion engine, it provides a spark plug 25 and a compression chamber 26, made in

20

blade x 7,

On the output shaft 27 there are two metal with rectangular cutouts of the disk 27 and 28 fixed fixedly relative to each other at the ends of the output shaft 21. Near the output shaft 21 there are fixed two contactless switches 29 and 30 on the brackets, the gaps of which include metal discs 27 and 28, and the electrical outputs of the switches 29 and 30 are connected by means of the adder 31 of the rectifier 32, the low-pass filter 33 and the amplifier 34 to the coil 35 of the solenoid 36, the core of which is spring-loaded from loan with a ring of mechanical adjustment of the working volume,

Volumetric rotary machine works

in the following way,

When a cylindrical rotor 4 rotates in a cylindrical housing 1 n in the absence of eccentricity in the working volume adjustment mechanism, the axis of the ring 11 coincides with the axis of shafts 5 and 6. When the drive shaft rotates, the angle between the cranks 13 and 14 does not change, and the driven shaft 6 rotates with the same soon

stew. When the ring 11 moves along the guides 2 of the housing 1, an eccentricity e occurs, while the rotation of the drive shaft 5 changes the angle between the cranks 13 and 14, with the result that the driven shaft 6 rotates at a variable speed. Since the speed increases during one half-turn and decreases during the next, the position of the cranks 10 relative to the rotor 4 of the machine changes accordingly. The cranks 0 through the rods 9 swing the blades 7 into the sector-like cavities 8 of the rotor, thereby ensuring the implementation of all the strokes of the three-dimensional rotary machine. The more the eccentricity of the transformation mechanism of uniform rotation into non-uniform, the more the angle between curvature 13 and 14, respectively the larger the angle relative to the rotor 4, the cranks 10 deviate, the greater the swing angle of the blades and the working volume of the machine.

Accounting for the effect of load on the amount of movement of the displacement adjustment mechanism in a machine is performed as follows. When the shaft 21 rotates, the disks 27 and 28 with rectangular cutouts pass into the openings of the contactless track switches 29 and 30, as a result of which the rectangular voltage pulses of the same height and duration are formed at the electrical outputs of both switches. Contactless grounding switches 29 and 30 are connected in such a way that the output pulse signals (Fig. 5a and 4b) are out of phase, therefore, in the absence of a load on the machine shaft, the output signal of the adder is zero. With increasing load on the shaft 21, a phase shift of the output pulse signals occurs (Fig. 5c and 4d). A signal appears at the output of the adder 31 (Fig. 5e), which is rectified by the rectifier 32 and is formed

signal (Fig. 5e). The received signal passes the low-pass filter 33 and is amplified by the amplifier 34, after which it is fed to the coil 35 of the solenoid 36. Under the action of this signal, the core of the solenoid 36 is moved, and with it the ring 11 moves, the eccentricity of the mechanism

The Q conversion of uniform rotation to non-uniform increases, and the working volume of the machine increases.

As the load on the machine shaft 21 decreases, the output signal decreases,

1g which leads to a decrease in the current in the coil of the solenoid, the core of the solenoid 36 and the ring 11 move in the opposite direction, resulting in a working volume of viburnum

2Q decreases.
