Abstract
It is an object of the invention to propose a mechanical gearing for a tuner for cavity resonators, which can be realized and operated in a less expensive version and with long service life and little backlash even at very low temperatures. At the same time, there is no piezoelectric or magnetostrictive driving mechanisms or their combinations with coarse driving mechanisms. The tuner includes a multi-stage lever mechanism, for which the fulcrum and the movable connecting site are integral and are connected over a narrow cross member. The connecting sites between the stages of the multi-stage lever mechanism are constructed as a bolt-shaped part, the ends of which are firmly connected with one stage and the middle part of which is connected with the other stage.
