| Abstract:
This invention relates to transmissions; that is to say, to devices for transmitting power to a machine or apparatus at changed speed from a prime mover such as an electric motor. More specifically, the invention has to do with transmissions in which the motion transfer is effected by planetary gearing. In connection with transmissions of the kind referred to it is my aim to secure a more uniform distribution of the load strains than Possible of attainment with transmissions as ordinarily constructed, with a view toward precluding or minimizing torsion in the shafting and gearing, thereby to assure more effective transmission of power and quieter operation with reduced wear, particularly in instances where frequent reversal is necessary or required in driving different types of machines or apparatus.
Claim:
A power transmission including a pair of shafts disposed in eccentric relation to each other; a spur gear pinion fixed on one of the shafts and meshing with a spur gear wheel free-to revolve about the other shaft; a spindle journaled in the spur gear in parallel eccentric relation to the second mentioned shaft; duplicate planetary pinions affixed respectively to opposite ends of the spindle and meshing with fixed-sun gears at opposite sides of the revolving gear wheel in concentric relation thereto; and a third pinion affixed medially of the spindle within a central hollow of said first mentioned gearwheel affixed to said second mentioned shaft. |
