SLACK-FREE PLANETARY GEAR TRAIN Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: slack-free planetary gear train has central wheels, one of which is fixed, carrier with two opposite eccentrics with fitted on bevel planet pinions. Planet pinions are made split and provided with additional ties limiting their rotation relative to axis. Such design makes it possible to provide independent adjustment of clearance in each engagement. Resilient compensators are used to compensate for wear of teeth. Each part of planet pinions rests on compensators. EFFECT: enlarged kinematic properties of gear train owing to use of planet pinions with two toothed rims. 5 cl, 11 dwg
