FIELD: machine building.
SUBSTANCE: belt gear system includes an endless belt enveloping drive pulley (1) and at least one driven pulley (2-4), which are flat pulleys. Power transmission between pulleys is performed actually through a flat working surface of the belt. On outer belt surface there is a lot of projections passing in longitudinal belt direction, which interact with annular grooves of restricting pulley (5, 6), which allows restricting belt movement for power transmission in transverse belt direction.
EFFECT: maintaining a stable belt operating mode; improving transmission efficiency and durability of a belt.
