摘　　要：采用永磁齿轮作为人工心脏驱动方式是一种新设想。在计算永磁齿轮矩角特性基础上,研究了气隙对传递最大转矩的影响,并探讨了永磁齿轮理想转动状况。建立了人工心脏模拟实验装置,实验验证了永磁齿轮在人工心脏设计中的适用性。An artificial heart using magnetic gears is a novel design. Based on the calculation of the relation between torque and angle of magnetic gears, the influence on the maximum torque from air gap is studied, and the ideal rotational status is obtained, too. The artificial heart simulation mechanism is established, and the experiment proved that magnetic gears are applicable in the design of artificial hearts.
