CONTINUOUSLY VARIABLE TRANSMISSION (OPTIONS) Russian patent published in 2022 - IPC F16H3/72 F16H37/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering to the mechanisms of stepless change of the gear ratio and can be used in transport, agriculture, machine-tool building, shipbuilding and other branches of mechanical engineering. In the first version, the continuously variable transmission includes a housing with a drive shaft 1 and an output shaft 16, a planetary gear set with a dome 5, a carrier 6 connected to the intermediate shaft 15 with a worm wheel 8 fixed on it. The dome 5 is connected to the intermediate shaft 15 by means of a worm gear, the drive shaft 1 and the output shaft 16 are mounted on bearings 17 in the housing 18. In this case, the sun gear 2 is engaged with the planetary gears 3 loosely seated on the bearings 7, and the planetary gears 3 are engaged with the ring gear 4 connected to the dome 5 Carrier 6 is connected to an intermediate shaft 15 mounted on bearings 10 and on which a worm wheel 8 is fixed, which is engaged with a pair of worm screws 9 mounted on bearings 12 in the dome 5 and having gears 11 at the end, which are engaged with gear 13 connected to the gear 14, and being coaxial to the dome 5, and the gear 14 is engaged with the neck stubble 19 connected to the shaft 20 mounted on bearings 22 in the housing 23 connected to the main body 18 and to the electric motor 21. 25 of the counterpart of the variator, mounted on the shaft 27, on which the gear 28 is also fixed, which is in engagement with the gear 29, mounted on the shaft 30, installed in the housing 23, and the gear 29 is in engagement with the gear 31, mounted on the drive shaft 1.

EFFECT: downsizing of the continuously variable transmission.
