TWO-SPEED DRIVE MECHANISM Russian patent published in 2011 - IPC F16K31/53 

FIELD: mechanical engineering.

SUBSTANCE: drive mechanism represents an oscillating gearbox and comprises a housing, three sun wheels, satellites. The driving wheel has external gears. The driven wheel has internal gears. The third wheel with external gears is supporting. The third wheel is fixed and rotates on the gearbox housing. The satellites interact with three sun wheels. A two-stand blocker provides either stopping of a supporting wheel with respect to a rack, or stopping of all gearbox wheels with respect to each other. The satellites are staggered in two layers. The inside layer satellites interact with the supporting wheel, while the outside layer satellites - with the driven wheel and the inside layer satellites. The driving wheel interacts with the outside layer satellites. The gearbox housing represents a cup with a bottom hole for a hollow shaft of a driving wheel and supplied with a mounting flange. The flange is attached to the body of a controlled object. The driven wheel is supplied with an outlet flange with a driving wheel resting against. The flange is used for coupling with a movable link of the controlled object. The driving wheel shaft passes in the hole of the supporting wheel.

EFFECT: downsizing and reduced metal consumption of the drive, simplified operator's work and higher labour capacity.
