Abstract

FIELD: engines and pumps.

SUBSTANCE: invention deals with design of pumps, compressor units and, principally, four-stroke combustion engines. The volume rotor machine contains a stator, a shaft with a tilted disk rotor rigidly mounted thereon, separator plates and varied volume operating chambers with inlet and outlet ducts. The rotor is composed of two mutually parallel planes slanted relative to the shaft axis. The four semi-circular separator plates carry out oscillating and swinging movements round a centre coinciding with that of the plate forming the semi-circle and lying on the line of the plate interaction with the rotor tilted plane during the rotor rotation. The pairs of plates, lying within the same plane and encompassing the rotor, are linked via bracer elements providing for engagement in the sliding contact of the plates to the rotor planes. Existence of the four plates results in construction of four varied volume operating chambers formed by the rotor planes, the plates and the stator inside surface. Inlet and outlet ducts of the operating chambers are designed to be from the stator butt-end side. In the stator butt-ends, between the parallel plates both sides of the shaft, there are the plate supports arranged. In the stator slots, on the supports and inside the rotor there are oil ducts arranged. The rotor (at the points of sliding contact to the stator) and the stator slots are fitted with sealant elements and oil scraper rings.

EFFECT: provision for simplified configuration of the structure manufacture and reduced number of frictionally interacting components which results in improved reliability and durability of the structure.

Description

Technical field

The invention can be used in mechanical engineering as a compressor, pump or internal combustion engine.

State of the art

The internal combustion engines used in shipbuilding are widely known, containing a body, pistons placed in cylinders, connected by connecting rods to crankshafts of a crankshaft [1] (Kane AB, “Shipboard internal combustion engines.” Textbook. Leningrad “Shipbuilding”, 1982. ) The disadvantages of internal combustion engines include the complexity of manufacturing the crankshaft, the friction of the pistons in the cylinders and the vibration from the unbalanced inertia of the moving masses.

Known rotary piston engine, which contains a housing, a cover located in the housing of the rotor with radial grooves in which the plate is installed. The internal space of the engine is formed by the surfaces of two hemispheres that enter one another, having a common center, but different radii, and a diametrical plane passing through the center of the hemispheres [2] (RU No. 2171896 C1, F01C 1/344, 2001). The disadvantages of this machine include the complexity of the layout in the manufacture and a significant number of interacting friction parts, which reduces its reliability and performance.

Known volumetric rotary machine containing a stator, the inner surface of which is made in the form of a body of revolution with a plane of symmetry perpendicular to the axis of rotation, a shaft with a rigidly mounted inclined disk rotor, dividing plates located parallel to the shaft on both sides at an equal distance from it in the grooves of the stator, with the possibility of each plate making oscillating and oscillating movements, and working chambers of variable volume with incoming and outgoing channels [3] (FR 639381 A, 06/20/1928, F04C 2/356). The disadvantages of this machine include low reliability and performance due to insufficient adhesion of the plates to the planes of the disk rotor.

SUMMARY OF THE INVENTION

The objective of the invention is to increase the reliability and performance of a volumetric rotary machine with the simplification of its design and reducing the number of interacting friction parts. The technical result is achieved by the fact that the inner surface of the stator of a volumetric rotary machine is made in the form of a body of revolution with a plane of symmetry perpendicular to the axis of rotation (from a cylinder to a sphere with truncated ends). A shaft is included in the cross section of the housing, coaxially with it, in the equidistant part of which an inclined disk rotor is rigidly fixed in the form of a body formed by two planes parallel to each other inclined to the shaft axis. Four semicircular dividing plates located in the stator slots are located parallel to the shaft on both sides and at equal distance from it, with the ability of each plate to oscillate and oscillate around a center that coincides with the center of the plate forming a semicircle and lying on the line of interaction of the plate and the inclined plane of the rotor during its rotation. Pairs of dividing plates lying in the same plane and covering the inclined disk rotor are interconnected by tightening elements (springs), which provide a snug fit in the sliding contact of the plates with the planes of the disk rotor. The presence of four dividing plates creates four working chambers of variable volume, formed by the planes of the inclined disk rotor, dividing plates and the inner surface of the stator. At the ends of the stator between the parallel dividing plates on both sides of the shaft, the stops of the dividing plates are made, while in the grooves of the stator, on the stops and in the rotor oil-conducting channels are made, and the rotor in the places of sliding contact with the stator and the grooves of the stator are equipped with seals and oil rings. Each chamber of variable volume on the side of the end face of the stator is equipped with an inlet and outlet channel, and in the embodiment of an internal combustion engine, with an ignition plug. The stops of the separation plates and the stator parts between the grooves are inserted.

Information confirming the possibility of carrying out the invention

The volumetric rotary machine comprises a stator 1, a shaft 2 placed therein with an inclined disk rotor 3, and dividing plates 4 mounted in the grooves 5 of the stator 1. Pairs of dividing plates 4 lying in the same plane and covering the inclined disk rotor 3 are connected by tightening elements 6. At the ends of the stator 1 between the parallel dividing plates 4 on both sides of the shaft 2 there are stops 7 of the dividing plates 4.

Volumetric rotary machine operates as follows.

When the shaft 2 is rotated, the inclined disk rotor 3 rigidly fixed on it interacts with a sliding contact with dividing plates 4 installed in the grooves 5 of the stator 1, rotates them around the center coinciding with the center forming the semicircle of each plate 4, and also moves one pair parallel to the axis of the shaft 2 plates 4, interconnected by pulling elements 6, down, and the other pair up, alternately changing the volume of each working chamber formed by the plane of the inclined disk rotor 3, a dividing plate 4 and the inner surface of the stator 1.

The proposed solution provides increased reliability and productivity of a volumetric rotary machine with a simplification of its design and a reduction in the number of friction-interacting parts.
