ELECTRIC DRIVE WITH THREE-STAGE PLANETARY REDUCTION GEARBOX Russian patent published in 2019 - IPC F16H1/48 

FIELD: machine building.

SUBSTANCE: drive contains the input shaft, which is connected to the electric motor, the planetary rows, the gear wheel and the output shaft. Sun gear of the high-speed row is mounted on the motor shaft and is connected to the high-speed carrier through satellites mounted on the axes and fixed through sleeves between the high-speed series disk and the high-speed carrier, and the intermediate-row sun-gear is made in one piece with the high-speed carrier and is connected with the intermediate carrier through satellites mounted on the axes and fixed through the sleeves between the intermediate-row disk and the intermediate carrier, as well as the sun gear of the low-speed row is made in one piece with the intermediate carrier and is connected with the low-speed carrier through satellites mounted on the axes and fixed through sleeves between the low-speed disk and low-speed carrier. Planetary rows are connected by the gear wheel by means of universal-sized satellites rotating on identical ball-bearing mechanisms, as well as on all the planetary gears, the disks, bushings, fluoroplastic bearings of the planetary rows and the axes of the high-speed and intermediate rows are made universal. Dual satellites and dual ball bearing mechanisms are installed on the low-speed row.

EFFECT: reduced dimensions and weight of the drive design.
