周边螺栓设计
在压电换能器中，一种采用一组螺栓（通常为 4、6 或 8 个）的设计：这些螺栓穿过后驱动块上的周边孔，并拧入前驱动块上相应的螺纹孔中。拧紧这些螺栓后，陶瓷被压紧在后驱动块与前驱动块之间，从而对陶瓷施加所需的预应力。对于这种设计，陶瓷呈圆盘形，通常没有中心孔。详见 ...
在某些设计中，周边螺栓可以用圆柱形外壳代替。例如，可参见 Jones 和 Maropis 的专利。对于这种设计，陶瓷呈圆盘形，并且可以开有中心孔，以便穿过电极导线。
Peripheral bolt design
In a piezoelectric transducer, a design that has a set of bolts (typically 4, 6, or 8) that are inserted through peripheral holes in the back driver and are threaded into corresponding holes in the front driver. When these bolts are tightened, the ceramics are compressed between the back driver and front driver, thereby applying the required prestress to the ceramics. For this design, the ceramics are shaped like disks and usually do not have a center hole. Details ...
For some designs, the peripheral bolts may be replaced by a cylindrical shell. For example, see the patent by Jones and Maropis. For this design, the ceramics are shaped like disks and may have a center hole to allow access for the electrode wires.
