Patent JP-H1030956-A (JP)
Title: Vibration receiver and manufacture thereof
Inventor: HACKEL UWE
IPC: G01H11/08
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To simplify the fixing of a coned disc spring and to avoid the unfavor able distortion of a detecting piece by performing laser welding of the coned disc spring to a pressure sleeve along the entire surface of the pressure sleeve. SOLUTION: When a knocking sensor is assembled, the entire torque affected by a fixing screw is transmitted to a pressure sleeve 2. Any force does not act on a piezoelectric ceramic disk 6 by fixing with a screw. Preload force required for the piezoelectric ceramic disc 6 is mechanically generated by compressing a coned disc spring 8 on a sesmic mass body 7, and then by welding the bonding parts between the coned disc spring 8 and the pressure sleeve 2 made of metal among the entire surface of the pressure sleeve with laser (laser welding joint/welding seam 31). After the laser welding joint/welding seam 31 is cooled or hardened, the preload is maintained without receiving other external action.
