摘　　要：对新型磁力金属带传动中传动比的影响因素 ,如有效牵引力、初张力、磁感应强度、中心距、小带轮直径及围包角等进行了分析和数值模拟 ,揭示了传动比随这些影响因素而变化的规律。结果表明 ,磁力金属带传动的传动比随磁感应强度、初张力及中心距的增大而增大 ,随围包角及小带轮直径的增大而减小。文中指出 ,由于磁力的作用 ,小带轮直径及其围包角均可相应减小 ,因此 ,其传动比较普通带传动可增加 3～Magnetic metal belt transmission is a new one in which the initial tension no longer solely, but together with the magnetic attraction force produces the friction force. The influencing factors on transmission ratio are analyzed and numerically simulated in this paper, such as effective haulage force, initial tension, magnetic induction intensity, center distance, diameter of the smaller belt pulley and angle of contact. The change laws of transmission ratio along with these influencing factors are studied. The results show that the transmission ratio of magnetic metal belt transmission increases when magnetic induction density, initial tension and center distance increases, and decrease when angle of contact and diameter of the smaller belt pulley increases. It is pointed out that the angle of contact and diameter of the smaller belt pulley can be reduced accordingly because of the effect of magnetic force, and therefore the transmission ratio can increase by 3～4 times compared with general belt transmission.
