FIELD: transport. ^ SUBSTANCE: proposed belt drive comprises two pulleys 3, 4 and belt 5. Pulleys 3, 4 are made up of magnet. Belt 5 comprises magnetic material. With pulleys running, belt is attracted thereto to create additional pressure force. In point wherein belt separates from pulley, magnet 6 is arranged to reduce pulley magnetic field acting on belt in separation zone and make said belt curvature minor. Belt tension and damping of its oscillation are ensured by attracting magnet 7. ^ EFFECT: higher reliability, reduced noise and radial loads on pulley. ^ 10 cl, 1 dwg |
