中心螺栓设计
在压电换能器中，一种用单根叠堆螺栓穿过压电陶瓷中心孔的设计。拧紧该螺栓后，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。在这种设计中，螺栓轴线与换能器轴线重合，陶瓷制成垫圈形（即带中心孔，以便为螺栓留出间隙）。详情 ……
Center bolt design
In a piezoelectric transducer, a design where a single stack bolt runs through a center hole in the ceramics. When this bolt is tightened, the ceramics are compressed between the back driver and front driver, thereby applying the required prestress to the ceramics. In this design, the axis of the bolt coincides with the axis of the transducer and the ceramics are shaped like washers (i.e., with a center hole that provides clearance for the bolt). Details ...
