FIELD: transportation.
SUBSTANCE: system from pulley and belt comprises multi-rib and multi-rib belt. Pulley comprises bearing surface, having ribs (201) and grooves (204), configuration of which is arranged with account of belt narrowing in case of stretching load. Step of pulley rib between neighboring ribs reduces as distance of every rib increases from middle line of pulley. Angle of pulley groove reduces as distance of every pulley groove increases from middle line of pulley. Step of pulley rib and angle of pulley groove is calculated with application of equations.
EFFECT: noise reduction and increased service life.
