Piezoelektrisches Wandlerelement und Verfahren zu seiner Herstellung

摘要

1. Method for the manufacture of a piezoelectric transducer element, particularly for incorporation in pressure, force or acceleration detectors, consisting of a securing part and at least one annular shear element of piezoelectric material with an open longitudinal slot shrunk-fitted on to the securing part by means of an outer surrounding shrink-ring, characterized in that the annular shear element is first assembled on the securing part by means of a likewise slotted setting-up ring encircling the shear element and is than firmly shrunk on to the securing part in known manner by the cooling of the heated shrink-ring positioned externally around the setting-up ring, whereby the setting-up ring prevents overheating of the annular shear element during the shrinking process.
