<p>A deviation mirror must be able to rotate at high speed around a first axle and independently of this, must be azimuthally tiltable around a co-rotating axle. The rotational movement is transferred to the mirror by a laterally-arranged motor by means of a toothed-belt drive, or directly by a co-axially arranged hollow-shaft motor via a first shaft and a mirror suspension. The tilting movement is achieved via tilting levers by the to- and fro-movement of a second shaft which rotates simultaneously inside the first shaft. The second shaft is coupled by an axial bearing to the to- and fro-movement of a spindle/nut arrangement which is actuated by a separate belt drive or another hollow-shaft motor. The first shaft, second shaft, spindle, nut and if necessary the hollow shaft motors are arranged co-axially.</p> |
