MULTI-SATELLITE DIFFERENTIAL GEAR AT PRECISION RECTILINEAR MOTION OF POINT ON SATELLITES Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed differential gear has movable sun gear wheel whose radius is lesser than two eccentricities of carrier, additional gear wheel and several additional satellites forming internal engagement with sun gear wheel. Radius of each satellite is lesser than eccentricity of carrier. Rotational speed of sun gear wheel ensures rotation of satellites and carrier at equal speed in opposite directions, thus making points on satellite move accurately in curvilinear direction without guide. EFFECT: extended functional capabilities. 3 dwg
