VARIABLE SPEED TRANSMISSION Russian patent published in 2018 - IPC F16H3/44 F16H47/08 F16H3/72 

FIELD: machine building.

SUBSTANCE: invention relates to a variable speed transmission. Variable speed transmission (1) comprises planetary gear mechanism (40) to which input shaft (20) and output shaft (30) are connected, and speed control mechanism (50), changing the speed of internal gear (41), sun gear (42) or planetary gear carrier (44). Mechanism (50) comprises input control shaft (51) and output control shaft (52), transfer mechanism (53) on the input side, speed change mechanism (54), and transfer mechanism (55) on the output side transmitting a torque from output control shaft (52) to internal gear (41), sun gear (42) or planetary gear carrier (44) to which neither input shaft (20) nor output shaft (30) is connected.

EFFECT: creation of an optimum design and efficiency increase are achieved.
