Embodiment
In order to understand technical scheme of the present invention better, below through concrete embodiment and combine accompanying drawing at length to explain:
See also Fig. 1 to Fig. 6, the comprehensive measurement device of gamma star bearing of the present invention comprises pair of supporting 1, single-revolution platform 2, a motor 3, a balancing weight 4, a pull bar 5, a connecting rod 6, a tension measurement device 7, one decibel of appearance 8 and computing machine 9, wherein:
Parallel and the compartment of terrain of pair of supporting 1 fixes on the ground, and the spacing distance of pair of supporting 1 is at least the width of panoramic table 2;
Owing to will dispose the bigger balancing weight of a quality 4; Two middle side parts of panoramic table 2 connect a rotating shaft 10 through a gravity centre adjustment mechanism respectively coaxially; These two rotating shafts 10 are installed on the pair of supporting 1 through bearing 11 respectively; Panoramic table 2 can 10 be done 360 ° of revolution around the shaft, with the real work state of simulation measured bearing 100; The central authorities of this panoramic table 2 offer a through hole 20, being centered close on the axis with two rotating shafts 10 of this through hole 20;
Outer end in a rotating shaft 10 of panoramic table 2 any sides connects a worm-and-wheel gear 12, and the other end of this worm-and-wheel gear 12 connects a handwheel 13; By the rotation of handwheel 13 driving rotational platforms 2, can guarantee the stability of rotation property of panoramic table 2, and can be arbitrarily angled static;
