摘　　要：针对大尺寸超声电机定子粘接难度大的问题,设计了一种分片式定子粘接的工艺方法。通过设计一个聚四氟乙烯定位环,将分片式压电材料拼接成环形的压电材料粘接到弹性体上。与传统的环片式粘接工艺相比较,分片式粘接工艺解决了大尺寸超声电机的粘接难度和大尺寸压电材料的制作与加工难度。同时对分片式压电材料进行分类组合,可以减小超声电机的两相静态电容差,提高超声电机的输出性能。To solve the problem of difficulty in bonding stator of large size ultrasonic motor,a technology method of segmental stator bonding was designed.By designing a positioning teflon,the segmented piezoelectric material was spliced into a ring piezoelectric material and bonded to an elastomer.Compared with the traditional ring plate bonding process,fragmentation bonding technology solved the difficulty of bonding large size ultrasonic motor and the difficulty of making and processing large size piezoelectric materials.At the same time,the classification and combination of segmented piezoelectric materials can reduce the two-phase capacitance difference of ultrasonic motor and improve the output performance of ultrasonic motor.
