摘要： 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.

摘要： Spindle nut holder for a spindle gear which drives a lever and functions under extreme conditions such as in a vacuum, under radiation exposure, and at a temperature close to absolute zero. The spindle nut holder includes a spindle nut and strip-shaped links each having an elongated, narrow cross section. One end of each link is connected to the spindle nut and the other end is connected to a frame. A pair of links are arranged on opposite sides of the spindle nut holder and each is oriented perpendicular to the spindle axis and the cross-section provides longer sides and shorter sides, the longer sides being parallel to the spindle axis. The cross-section of another link provides longer sides and shorter sides and is arranged relative to the pair of links such that the longer sides of this link are perpendicular to the longer sides of the pair of links.
