Abstract

Inventia se refera la industria constructoare de masini, si anume la masini hidraulice cu rotor. Masina hidraulica contine un stator (3) cu coroana dintata interioara (4), un rotor (5) cu coroana dintata exterioara, amplasat excentric in interiorul statorului cu formarea camerelor de lucru si cuplat rigid cu un arbore (1), distribuitoare frontale (11, 12), in care sunt executate canale de debitare (13) si de evacuare (14) a lichidului de presiune si, cuplate cu ele, cavitati inelare (21-24) cu canale axiale (17-20), bucse (33, 34) montate coaxial in fiecare din distribuitoarele frontale si inele de etansare de presiune inalta (35, 36), amplasate intre distribuitoarele frontale si rotor. In fiecare distribuitor frontal sunt executate cate doua cavitati inelare, totodata, doua cavitati inelare (21, 22), executate respectiv in ambele distribuitoare, sunt cuplate printr-un canal axial (28) in stator cu canalul de debitare a lichidului de presiune, iar altele doua (23, 24) - printr-un alt canal axial (32) in stator cu canalul de evacuare a lichidului de presiune, in fiecare bucsa sunt instalate din partea rotorului inele de etansare de presiune joasa (37, 38) si executate cate doua canale axiale in trepte (42-45), in fiecare fiind montata o supapa de retinere (46-49), intrarea fiecareia fiind cuplata cu cavitatea dintre inelele de etansare, iar iesirea - cu canalul de evacuare a lichidului de presiune.The invention relates to the machine building industry, namely to hydraulic machines with rotor. The hydraulic machine contains a stator (3) with inner toothed crown (4), a rotor (5) with outer toothed crown, located eccentrically inside the stator with the formation of work rooms and rigidly coupled with a shaft (1), front distributors (11) , 12), in which flow channels (13) and outlet (14) of the pressure liquid are executed and, coupled with them, annular cavities (21-24) with axial channels (17-20), bushings (33, 34) coaxially mounted in each of the front distributors and high pressure sealing rings (35, 36), located between the front distributors and the rotor. In each front distributor, two annular cavities are executed, at the same time, two annular cavities (21, 22), executed respectively in both distributors, are coupled through an axial channel (28) in the stator with the pressure liquid flow channel, and two others (23, 24) - through another axial channel (32) in the stator with the outlet channel of the pressure liquid, in each bushing are installed from the rotor low pressure sealing rings (37, 38) and executed each two axial channels in steps (42-45), in each being fitted a retaining valve (46-49), each inlet being coupled with the cavity between the sealing rings, and the outlet - with the outlet channel of the pressure fluid.
