VARIABLE-SPEED GEAR WITH SHIFTED AXES OF ROTATION Russian patent published in 2015 - IPC F16H3/44 

FIELD: transport.

SUBSTANCE: in planetary gear each toothed satellite is rigidly connected with one more additional carrier. On additional carriers, more several tapered not toothed satellites are located which are kinematically interconnected by not toothed wheel. Tapered not toothed satellites can engage and disengage with guides located on gear wheel kinematically connected with outer wheel of planetary gear, satellite gears can roll over guides, the guides can rotate and roll over gear rack with possibility of fixation in specified position. When gear wheels roll over the rack the guides can roll and rotate together with these wheels, shafts of guides are connected by means of holders are connected with disk not toothed wheel located on output shaft, the shaft has rigid connection with wheel which is kinematically connected with outer wheel of planetary gear, disk not toothed wheel can rotate together with wheel which has kinematic connection with outer wheel of planetary gear and shift along rotation axis of shaft on which this wheel is located. The disk not toothed wheel is in contact with not toothed wheels fixed on actuating shaft, not toothed wheels on actuating shaft can roll over surface of disk not toothed wheel and to shift together with this wheel and actuating rod along rotation axis of the mentioned shaft, actuating shaft is connected with driving gear.

EFFECT: smooth variation of gear ratio.
