Guide element for drives with concentric translators and elastic elements

摘要

Each of three elastic elements (2) equi-spaced round the periphery of the guide each consists of a flat strip in the non-deflected setting to lie in spiral or twisted form in this plane. Several guides may be arranged coaxially in series so the stator (1) of the succeeding element can be rigidly joined to the translator (3) of the preceding element, or in a case where several elements are joined up in parallel, their respective stators and translators may be connected to one another. The elastic elements can be fitted with piezoelectric elements and the translator is connected to an electromagnetic drive and to a coaxial membrane. The guide can combine with a fibre-optic sensor, either as fibre light guides applied to the element or again the entire element made of a glass structure thus transmitting light signals from sender (7) into the fibre light guides (4) for routing to a reflection area (5) and/or to a receiver (6).
