FIELD: mechanical engineering.
SUBSTANCE: differential mechanism comprises housing (1), parallel shafts (5) and (4), screw (2), and nut (3). Nut (3) cooperates with screw (2) through the kinematic link composed of three pairs of gearing wheels. Screw (2) can move along the axis. The number of teeth of conical wheel of first shaft (5) of electric motor (6) is determined by the number of teeth chosen from the specified interval from 13 to 157. The product of the number of teeth of conical wheel fit on nut (3) and cylindrical wheel fit on shaft (4) is determined from the formula proposed.
EFFECT: expanded functional capabilities.
