IMPROVED POWER DENSITY OF REVERSIBLE VARIABLE TRANSMISSION (RVT) Russian patent published in 2018 - IPC F16H61/664 F16H15/38 F16H55/34 

FIELD: electronics.

SUBSTANCE: group of inventions relates to planetary variators. Planetary variator, Functioning as a subsystem for variable or reversible transmissions, is capable of sustaining a squeezing pressure typically within but not limited to the range of 20 to 150 bar. Variator comprises a ring wheel, two or more planets mounted around a central shaft, and a sun wheel, such that ring wheel, central shaft and sun wheel form an interface with other transmission components. Each planet comprises a planet wheel running on the running surface of said sun or ring wheel, and a planet fork connecting the planet to said central shaft. continuous or a discontinuous control system is integrated in the assembly of each of the planets to ensure that the tip of the cone formed by the theoretical, non crowned, planet wheel running surface coincides precisely with the hinge axis of the planet fork when a certain load is applied on the running surface. Transmission comprising this variator and the use of the transmission or variator in engineering and industry are also disclosed.

EFFECT: improved performance of the planetary variator.
