Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
Embodiment one,
As shown in Figure 1 and Figure 2, a kind of pitch drive for vehicle-carrying communication antenna, comprise cylinder 5, described cylinder 5 by be erected at the support of clutch shaft bearing 1 on left support abutment 3 and right support abutment 8 and can to rotate relative to left support abutment 3 and right support abutment 8, the both ends of cylinder 5 be circumferentially fixedly installed left bracket 2 for fixedly mounting antenna 11 and right axle seat 10 respectively; Be provided with stationary magazine creel 6 at the cylinder chamber internal frame of cylinder 5, the cylinder cavity wall of cylinder 5 is connected by the second bearing 9 with between stationary magazine creel 6, and one end of stationary magazine creel 6 is fixed by connector and right support abutment 8; The power set rotated for head roll 5 are arranged in the cylinder chamber of stationary magazine creel 6.
Described power set comprise motor 7 and planetary reduction gear 4, motor 7 and planetary reduction gear 4 are all fixed on the cylinder cavity wall of stationary magazine creel 6, the power output shaft of its motor connects the power input shaft of planetary reduction gear 4, the power output shaft of planetary reduction gear 4 is connected with driven wheel, circumferentially be provided with bull gear at cylinder 5 cavity walls with driven wheel relevant position, the bull gear driving gear drives cylinder 5 that is meshed with driven wheel rotates.
As second embodiment, driven wheel can be replaced with friction pulley 12, circumferentially just large bull gear can not be set like this at cylinder 5 cavity walls, the function that head roll 5 carries out rotating can be played equally.
As the 3rd embodiment, described driven wheel stretches out from the left end of cylinder 5, left bracket 2 with leg on be provided with gear hobbing, driven wheel is meshed with gear hobbing, thus head roll 5 rotates.
