FIELD: machine building.
SUBSTANCE: system of reducer consists of multitude of three-step modules (26A, 26B, 26C) of power tooth gear dividing flow of torque; each module transmits torque from high-speed engine to shaft (24) of lifting screw. A packaged design of a conic flat tooth gear of the first step (S1) facilitates installation of the engine in various positions along all axes. On the second step (S2) units of hollow shafts ensure equal balance of load. On the third step (S3) each unit of the hollow shaft includes multitude of small gears engaging an output tooth gear (28) of the last step.
EFFECT: reduced weight and dimension, equal distribution of load and simple and inexpensive production.
