POWER CONVERTER BASED ON PLANETARY CYCLO GEAR BOX (PCPCGB) Russian patent published in 2014 - IPC H02K7/116 F16H1/32 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering, in particular, to power converters made as gear motors and electric drives; it can be used in special-purpose power converters in the form of power generation stations and machines in machine-building industry, transport industry, oil and gas industry, power industry, etc for the purpose of conversion of mechanical power to electrical one by means of power conversion of the primary actuator with use of power of hydroflow and wind, sun and other kinds of mechanical power (combustion engines, etc.) to electric and heat power and pressure, etc. The suggested power converter contains the primary actuator (PA) which is an electric motor, planetary cyclo gear box (PCGB) fixed at PCGB shaft through bearings that transmits rotation to the output shaft of reduction gearbox. At that convex-profiled teeth of the gearbox central wheel engaged with concave-profiled teeth of the gear wheel being a satellite gear are made as barrel-type spiral rollers made of steel or springs of cylindrical, conical and spherical shape, and their barrel radius R is defined as per Hertz formula to minimise contact stress of engagement thus providing free from play, noiseless and optimal operation in terms of their durability.

EFFECT: this construction of power converter based on planetary cyclo gear box provides technical result consisting of improvement of energy characteristics, reliability and operational life of the converter with efficiency factor ≥ 95%.
