PLANETARY MECHANISM FOR VARIABLE-SPEED DRIVE REGULATION Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: planetary mechanism for variable-speed drive regulation has two similar planetary gear sets with common epicycle whose one sun gear is connected with drive shaft and other sun gear is connected with regulating mechanism. Carrier of one set is connected with housing and carrier of second set is connected with independent regulator. Each planetary gear set has one satellite with two gear rims. Axes of rotation of carrier and satellite are shifted and are located at distance from each other which is less than radius of lesser gear rim of satellite. EFFECT: enhanced efficiency. 2 cl, 3 dwg
