Description

The utility model relates to mechanical engineering, in particular to rotary machines, pumps, hydraulic motors and engines; it can be used in hydraulic rotary motion drives used in machine tool building, press machine-building (injection molding machines), agricultural machine-building, road-building machines and other industries, for example, compressor-building .

A “rotor machine” is known from the “prior art”, comprising a casing in the inner cavity of which, with the formation of working chambers, two rotor blades mounted on concentric shafts and a synchronization mechanism including a planetary gear, the carrier of which is connected to the output shaft mounted coaxially with the longitudinal axis of the machine. In this case, the central wheel is connected to the housing, and the satellite is kinematically connected to the rotors by a kinematic connection with a fork (see AS USSR No. 1751407, class IPC F04C 2/00, 18/00 publ. 30.07.1992).

The disadvantages of the known device are low performance due to pneumohydraulic and mechanical losses during the movement of the blades, low efficiency.

The objective of this utility model is to eliminate the above disadvantages.

The technical result is to improve operational characteristics with a decrease in pneumohydraulic and mechanical losses and increase the efficiency of the device.

The technical result is ensured by the fact that the rotor device comprises a stationary housing with a working chamber, windows for supplying and discharging the working medium in communication with pressure and drain lines, a rotor mounted in a fixed housing on the shaft, blades. The device further comprises a shaft eccentrically located relative to the rotor shaft. In this case, the blades are movably attached to the rotor and the shaft, which is eccentrically located relative to the rotor shaft.

In accordance with particular cases, the device may have the following design features.

The rotor contains a disk baffle with holes that provide the possibility of movable fixation of the blades relative to the rotor.

On the edges of the blades made protrusions, providing the possibility of movable fixation of the blades relative to the rotor, due to the coupling of the protrusions with holes in the disk partition.

The rotor contains cylindrical protrusions, providing the possibility of movable fixation of the blades relative to the rotor, due to the mating of the protrusions in the reciprocal grooves on the edges of the blades.

The rotor device comprises a fixed housing 1 with a working chamber 2, windows for supplying and discharging the working medium in communication with the pressure and drain lines, a rotor 3 mounted in a fixed housing 1 on the shaft 4, blades 5, characterized in that it further comprises a second shaft 6, eccentrically located relative to the rotor shaft 4, while the blades 5 are movably attached to the rotor 3 and the second shaft 6, which is eccentrically located relative to the shaft 4 of the rotor 3.

The eccentric location of the shaft 6 relative to the shaft 4 of the rotor 3, as well as the movable fixation of the blades 5 relative to the shafts 4,6, provides during the rotation of the blades a change in the volume of the cavities formed by the walls of the blades 5 from maximum to minimum. Thus, the mixture is compressed, which allows to increase the efficiency without increasing the consumption of the combustible mixture.

In addition, the features of the constructive implementation ensures the prevention of jamming of interacting elements of the rotor-blade mechanism, the reduction of friction in the working surfaces of friction, and the reduction of general mechanical losses.

According to the first particular case of execution (see Fig. 2), the rotor comprises a disk partition 7 with holes 8, which enable the movable fixing of the blades 5 relative to the rotor. In addition, on the edges of the blades 5, protrusions 9 are made, which enable the movable fixation of the blades 5 relative to the rotor 3, due to the coupling of the protrusions with the holes in the disk partition 6.

According to the second special case of execution (see Fig. 3), the rotor 3 contains cylindrical protrusions 10, which enable the movable fixing of the blades 5 relative to the rotor 3, due to the mating of the protrusions 10 in the mating grooves 11 on the edges of the blades 5.

The blades 5 are movably attached to the rotor 3 and the second shaft 6, which is eccentrically located relative to the shaft 4 of the rotor 3, by means of a swivel joint 12 (bearing).

The device operates as follows.

The working medium moves from the inlet window to the outlet window with blades 5 that rotate, as well as reciprocating movements relative to the rotor 3 and the second shaft 6 when they rotate, moving forward and backward, due to the presence of protrusions 9, 10, holes 8 and grooves 11, s the ability to slip.

When used as an engine, the rotor 3 is accelerated together 5 from an external source, for example, a starter (not shown in the drawing), or through the flywheel, through the inlet window into the cavity 2, the working mixture is fed, the rotor 3 is rotated, while the mixture is compressed. The compressed mixture is transferred to the area where the spark constantly sparks in the ignition chamber, the combustible mixture ignites and the process of its combustion with expansion of the gas occurs (working stroke). At the same time, the power take-off shaft rotates, from which the torque is removed by the consumption source. With the movement of the rotor 3, the cavities formed by the walls of the blades 5 are moved and for one revolution of the rotor 3, each cavity sequentially carries out the processes of intake, compression, combustion and expansion, exhaust, which make up a four-stroke cycle.

When used as a pump, operation is carried out by a drive motor. The rotor 3 rotates, the blades 5 also rotate. In this case, the process of pumping and sucking up the liquid occurs.
