FIELD: mechanical engineering; drives. ^ SUBSTANCE: proposed drive has drum 1, shaft 2 on which planetary gear trains are installed parallel to each other. Each planetary gear train, 3 and 4, respectively, consists of sun gear 5, 6, idler gear 7, 8 and crown gear 9, 10 made in form of toothed rims, one of which is connected to inner surface of drum, and the other, to fixed frame 17. Carrier 11 connected to idler gears 7, 8 interacts with shaft 2, being installed for rotation around shaft. Device providing power action on drum 1 is made in form of weight 15 connected through wire rope to drum 1 or, in form of spring 16, connected by one end to outer surface of drum 1 and by other end, to fixed object. Flow of gravitational or potential energy gets partially to first planetary gear train 3, and partially, through carrier 11, to second planetary gear train 4 and then to drive shaft 2, thus creating excess torque and increasing effectiveness of drive. ^ EFFECT: increased effectiveness of drive at enlarged area of its application. ^ 2 cl, 2 dwg |
