FIELD: mechanical engineering; applicable as conversion mechanisms in devices of rotor type, variable-speed drives, drives, mechanisms of intermittent rotation, etc. SUBSTANCE: conversion differential gear has two coaxial output shafts with rigidly secured sun gears, one of which is installed with displacement relative to its rotation axis and has nonround shape and similar number of teeth with engaged round satellite gears eccentrically displaced through the same value, carrier carrying axles of two-row satellite gears engageable with sun gears and ensuring kinematic connection between output shafts. Output shafts are composite and formed of several hollow coaxial shafts with sun gear secured to them forming composite sun gears kinematically connected through their two-row satellite gears. Composite output shaft connected with composite nonround sun gear has device fixing or allowing regulation of angular positions of nonround sun gear relative to one another. Invention provides for production of sequence of pulses of nonuniform rotation on composite output shaft of differential gear with variable in value speeds of rotation of driven links required direction of rotation and their mutual phase shift at constant speed of rotation of driving link. EFFECT: higher efficiency. 2 cl, 1 dwg
