Abstract
539,386. Reverse gearing. SALERNI, P. M. Dec. 5, 1939, No. 31553. [Class 80 (ii)] In an epicyclic gear a slidable sleeve 13 splined on an extension of the planetary cage 9 has dogs 14 engageable with dogs 12 on the annulus 10 and with dogs 15 on a fixed member 16 to give a solid drive and a reverse drive, respectively. The dogs 14 engage with the dogs 15 before disengaging from the dogs 12. As shown, the sun wheel 7 is fixed to a driving shaft 6 which may be the turbine member of a hydraulic power transmitter. The annulus 10 is secured to the driven shaft. The member 16 is carried by pins 17 and can yield axially against springs 19, 19a. The sleeve 13, which is shown in the neutral position, is moved by a yoke 20 actuated by an arm 24 on a shaft 25, the movement being assisted by springs 23. A brake band 29 cooperates with a drum 28 on the shaft 6 to bring the latter to rest to facilitate engagement of the gear from the neutral position. A spring-pressed pin 26 carried by the planetary cage 9 is engageable with recesses 27 in the sleeve 13 to hold the latter in the neutral, forward, and reverse drive positions.
