FIELD: transport.
SUBSTANCE: chain variator comprises hub 1 whereon sprockets 2 are fitted with offset axles 3. Said sprockets are fitted radially directly on said hub. Torque is transmitted from said hub or thereto by sprockets via chain. Sprockets may be locked in required position by friction, hydraulically, electrically etc. Varying position of said sprockets allows varying torque, hence, gear ratio.
EFFECT: longer life and higher reliability.
