Zusammenfassung:The invention relates to a differential reducer with two reduction stages, used in the mechanical transmission between a driving motor and a working machine or a driven technological equipment. The differential reducer with two reduction stages provides the mechanical transmission by that the bevel pinion (1) drives two kinematic chains, one consisting of two conical gear-wheels (3 and 4), which have an equal teeth number, integral with other cylindrical wheels (3' and 4') whose teeth number differ by a tooth and with opposite rotation senses, which, in their turn, drive two cylindrical crowns (5 and 6) which have an equal number of teeth and opposite rotation senses and which transform the relative rotation motion into opposite senses in relation to the senses of the two cylindrical crown gears (5 and 6) from the second stage, by two satellites (8) and by a grooved satellite holder (9), in the continuous rotation movement, they transmit to an output shaft (7) whose speed is equal to the difference between the speed of the conical crowns (5' and 6'), and the rotation sense and the final speed is given by the cylindrical crown (6) with the higher speed and the two linkages have very close final speeds but opposite rotation senses from whose difference there results a higher transmission ratio actuated by the same pinion. Invenţia se referă la un reductor diferenţial cu două trepte de reducere, utilizat la transmisia mecanică între un motor de antrenare şi o maşină de lucru sau un utilaj tehnologic antrenat. Reductorul diferenţial cu două trepte de reducere asigură transmisia mecanică prin aceea că pinionul conic (1) antrenează două lanţuri cinematice, unul alcătuit din două roţi dinţate conice (3 şi 4), care au număr egal de dinţi, solidare cu alte roţi cilindrice (3' şi 4'), al căror număr de dinţi diferă cu câte un dinte, şi cu sensuri de rotaţie opuse, care, la rândul lor, antrenează două coroane cilindrice (5 şi 6), al căror număr de dinţi diferă tot cu un dinte, şi sunt solidare cu alte coroane conice (5' şi 6'), care au număr egal de dinţi şi sensuri de rotaţie opuse, şi care transformă mişcarea de rotaţie relativă în sensuri contrare faţă de sensurile celor două coroane cilindrice dinţate (5 şi 6), din treapta a doua, prin doi sateliţi (8) şi printr-un port-satelit canelat (9), în mişcarea de rotaţie continuă, pe care o transmit unui arbore de ieşire (7) a cărui turaţie va fi egală cu diferenţa dintre cea a coroanelor conice (5' şi 6'), iar sensul de
