(54) РОТОРНАЯ МАШИНА(54) ROTARY MACHINE

1one

Изобретение относитс к машиностроению , в частности к роторным машинам.The invention relates to mechanical engineering, in particular to rotary machines.

Известна роторна машина, содержаш ,а корпус с торцовыми крышками, внутренн поверхность которого выполнена в виде цилиндра, эксцентрично расположенный в корпусе ротор, в радиальных пазах которого размещены пластины, снабженные на торцах выступами, и направл ющие колыша дл вые-, тупов, расположенные концентрично с внутренней поверхностью корпуса и установленные в подшипниках, расположенных в кольцевых выточках торцовых крышек 1.Known rotary machine, containing, and a housing with end caps, the inner surface of which is made in the form of a cylinder, an rotor eccentrically located in the housing, in the radial grooves of which there are plates fitted with protrusions on the ends and guides of the hub, located concentrically with the inner surface of the housing and installed in bearings located in the annular recesses of the end caps 1.

Однако известна машина обладает недостаточной надежностью уплотнени .However, the known machine has insufficient sealing reliability.

Цель изобретени - повышение надежности уплотнени .The purpose of the invention is to increase the reliability of compaction.

Указанна цель достигаетс тем, что в роторной машине направл ющие колЬца снабжены кольцевыми пазами, а выступы пластин выполнены в виде кольцевых секторов .This goal is achieved in that in the rotary machine the guide rings are provided with annular grooves, and the protrusions of the plates are made in the form of annular sectors.

Причем центры радиусов кривизны поверхностей кольцевых пазов и центры радиусов кривизны поверхностей выступов пластин расположены на окружности, образующей внутреннюю поверхность корпуса. .Moreover, the centers of the radii of curvature of the surfaces of the annular grooves and the centers of the radii of curvature of the surfaces of the protrusions of the plates are located on a circle forming the inner surface of the housing. .

На фиг. 1 представлена часть роторной маши-ны, продольный разрез; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a part of a rotary machine, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

Роторна машина содержит корпус I с торцовыми крышками 2, внутренн поверхность 3 которого выполнена в виде цилиндра , эксцентрично расположенный в корпусе 1 ротор 4, в радиальных пазах 5 которого размещены пластины 6, снабженные на торцах 7 выступами 8, и направл ющие кольца 9, расположенные соосно с ротором 4 и установлен10 ные в подшипниках 10, расположенных в кольцевых выточках 11 торцовых крышек 2. Направл ющие кольца 9 снабжены кольцевыми пазами 12, в которые вход т выступы 8, выполненные в виде кольцевых секторов. 15 При этом центры радиусов кривизны поверхностей 13 кольцевых пазов 12 и центры радиусов кривизны поверхностей 14 выступов 8 расположены на окружности 15, образующей внутреннюю поверхность 3 корпуса 1. .The rotor machine includes a housing I with end caps 2, the inner surface 3 of which is made in the form of a cylinder, the rotor 4 is eccentrically located in the housing 1, in the radial grooves 5 of which plates 6 are provided, fitted on the ends 7 with protrusions 8, and guide rings 9 arranged coaxially with the rotor 4 and mounted in bearings 10, located in annular recesses 11 of end caps 2. Guiding rings 9 are provided with annular grooves 12, which include protrusions 8 made in the form of annular sectors. 15 In this case, the centers of the radii of curvature of the surfaces 13 of the annular grooves 12 and the centers of the radii of curvature of the surfaces 14 of the protrusions 8 are located on a circle 15 forming the inner surface 3 of the housing 1..

Claims

When rotating the rotor 4 and the plates 6, placed in its radial grooves 5, the guide rings 9 also rotate, but since the axis of rotation of the plates 6 does not coincide with the 392 axis of rotation of the guide rings 9, the plates 6 perform math oscillations with respect to guide rings 9, moving projections 8, made in the form of annular sectors, along annular grooves 12, provide a more complete fit of the plates 6 to the inner surface 3 of the housing 1 and, therefore, more reliable sealing. The technical and economic effect is to increase the reliability of compaction, which leads to an increase in the efficiency of the rotor maschine. Claim 1. Rotary machine, comprising a housing with end caps, the inner surface of which is made in the form of a cylinder, an eccentric rotor located in the housing, in the radial grooves of which there are plates fitted with protrusions on the ends, and guide rings for the projections arranged concentrically with the inner surface of the housing and installed in the bearings, located in the annular recesses of the end caps ,. characterized in that, in order to increase the reliability of the seal, the guide rings are provided with annular grooves, and the protrusions of the plates are made in the form of annular sectors.

2. The machine according to claim 1, characterized in that the centers of the radii of curvature of the surfaces of the annular grooves and the centers of the radii of curvature of the surfaces of the protrusions of the plates are located on a circle forming the inner surface of the housing.
