摘　　要：为了提高复合振动体型超声波电机的效率 ,利用润滑剂在动压下混合润滑的特点 ,试制了与润滑摩擦驱动相适应的新型转子和定子 ,检测和分析了油膜的形成 ,转子、定子间的相对变位和扭转振动速度的关系以及电气 -机械变换效率、转速、扭矩等。实验结果表明 ,干磨擦驱动时的电机效率为 4 0 %左右 ,注润滑油润滑驱动时 ,电机效率可以达到 70 %。In order to increase the efficiency of the hybrid transducer ultrasonic motos ,utilizing the feature of the mixed lubrication of the lubicant under dynamic pressure, a new type of rotor and stator is made trial production to suit the lubrication friction drive. It also inspects and analyses the foming of the oil film, the relation between the relative shift of the rotor and stator and velocity of the torsional vibration, efficiency, rotation, toque etc. The result of the experiment indicates that the efficiency of the ultrasonic motor is about 40 percent under dry friction condition, while can achieve 70 percent under lubrication drive.
