Positive drive lineally variable speed device

Abstract

Abstract AN AXIAL SHAFT PLANETARY GEAR TYPE, LINEALLY VARIABLE SPEED DEVICE, THE SUN MESHED PLANET GEARS OF WHICH ARE EACH INDEPENDENT AND ROTATABLY SUPPORTED THROUGH A CONNECTING CLUTCH BY THEIR RESPECTIVE RACK OPERATED PINION, THE STROKE OF THE RACK OF WHICH VARIES THE SPEED OF THE OUTPUT SHAFT OVER THAT OF THE INPUT SHAFT. A SHAFT MEANS TRANSVERSE OF THE AXIAL INPUT AND OUTPUT SHAFTS OF THE TRANSMISSION IS PROVIDED AND IS INDEPENDENTLY ROTATABLY SUPPORTING THE PLANET GEARS WITH THEIR RESPECTIVE CLUTCHES AND PINIONS, THE LATTER DRIVEN BY THEIR RESPECTIVE RACKS MOVABLE PARALLEL RELATIVE TO THE ROTARY ALIGNED AXIS OF THE DEVICE AND CARRYING ANTIFRICTION FOLLOWERS ENGAGED BY A TRACK MEANS ADJUSTABLY MOVABLE AXIALLY TO OBTAIN VARIABLE SPEEDS OVER THE ONE-TO-ONE RATIO OF THE SPEED DEVICE. THE USE OF THE TRANSVERSE SHAFT IN THE ROTARY PLANETARY SYSTEM SIMPLIFIES THE STRUCTURE BY PERMITTING THE USE OF PARALLEL ALIGNED RACKS ROTATABLE ABOUT TO ENGAGE THE TRACK MEANS AND PRODUCE HAVING FOLLOWERS TO ENGAGE THE TRACK MEANS AND PRODUCE A STRAIGHT LINE SPEED VARIATION. IT IS NOT A SINUSODIAL RELATION. THIS IS IMPORTANT IN MANY USES OF THIS TYPE OF DEVICE IN POWER TRANSMISSION.
