FIELD: machine engineering, namely stable-speed drives of subsidiary aggregates. ^ SUBSTANCE: drive includes planetary ball gearing 1000 with gradual variation of gear ratio; step motor, worm gearing. Planetary ball gearing includes planetary members having rolling contact with inner and outer raceways and it may gradually vary gear ratio in range 0.3 - 1.0. Inlet shaft of said gearing is joined with primary propeller such as crankshaft of transport vehicle engine through driving belt B1. Gearing includes at least one outlet shaft coaxial to inlet shaft. Processor analyzes revolution number of crankshaft and respectively varies gear ratio with use of step motor joined with worm gearing for keeping stable revolution number at outlet regardless of revolution number of crankshaft. ^ EFFECT: possibility for keeping stable revolution number of gearing regardless of revolution number of crankshaft of primary propeller. ^ 21 cl, 18 dwg, 3 tbl |
