2-STGZ/D airborne vehicle mounted tracking turntable
The pitch axis of the 2-STGZ/D2-STGZ/D airborne vehicle mounted tracking turntable adopts a single arm type, and the horizontal axis adopts a rotating type. The optical lens diameter carried is only 100mm, and the weight is less than 10kg. The turntable rotation is directly driven by a motor, and the mechanical interface between the motor and the shaft system needs to be coordinated and determined with the motor research unit.
(1) Range of azimuth rotation: ± 175 °;
(2) Pitch rotation range: 0 ± 80 °;
(3) Rotary accuracy of the turntable shaft system: not greater than 2 inches;
(4) Verticality of the turntable shaft system: not greater than 5 inches;
(5) Direction rotation friction torque: not greater than 800g? Cm (fluctuation not exceeding 5%, full load);
(6) Pitch rotation friction torque: not greater than 400g? Cm (fluctuation not exceeding 5%, full load);
(7) First order resonant frequency (after carrying): ≥ 75Hz;
(8) Load capacity of the turntable: not less than 10kg;
(9) Installation surface flatness: better than 0.1mm/global;
(10) Installation surface roughness: Ru3.2.
