PLANETARY GEAR-BOX OF TRANSPORT FACILITY Russian patent published in 2003 - IPC

FIELD: mechanical engineering; transmissions of transport facilities. SUBSTANCE: three satellites 7, 8 and 9 are connected respectively as follows: first satellite 7 is connected with first central gun gear wheel 5; second satellite 8 is connected with epicyclic gear wheel 10 and third satellite is connected with second central sun gear wheel 6. Input shaft 2 is linked with epicyclic gear wheel 10 through first locking friction clutch 12. Input shaft 2 is also connected with first central sun gear wheel 5 by means of overrunning clutch 13. Carrier 11 is stopped by means of brake 14. Output shaft 3 is linked with central sun gear wheel 5 by means of second locking friction clutch 15 and with central sun gear wheel 6 by means of overrunning clutch 16. EFFECT: avoidance of flow discontinuity in change-over operations. 1 dwg
