Abstract
The utility model relates to an antenna driving structure of a portable satellite station; a stepping motor is connected with a worm and gear mechanism by a shaft joint, and the worm and gear mechanism drives a rotating disk; the rotating disk and an antenna rotating platform are fixed by a bolt; the stepping motor is connected with a manual regulating handle which is linked with the stepping motor; the antenna rotating platform rotates by automatically or manually driving the antenna, thus realizing accurate location of the antenna. The antenna driving structure has the advantages of small volume, light weight and big force moment; outputting precision of a speed reducer is high and shaking quantity is low; under power-off condition, the manual regulating handle is rocked for rotating the stepping motor.
Description
Technical field
The utility model relates to a kind of day line transmission mechanism, be particularly related to a kind of portable satellite station antenna system that is applied to, in the process of the automatic searching satellite of satellite system, drive satellite antenna and antenna feed, realize smoothly portable satellite station antenna drive mechanism to star.
Background technology
Portable satellite station antenna system is integrated with it, miniaturization, intelligentized characteristics, be applied to not possess the wild environment of communication condition, be applicable to special users such as government emergency Office of the Telecommunications Authority, news media, public security, frontier defense, army, play the emergency communication effect.The machine driven system of antenna occupies critical role in whole system, it is to realize that satellite system is quick, the basis of hi-Fix.In satellite system, orientation positioning of rotating and antenna, feed pitching location are arranged.Its designing requirement has:
1) reductor output accuracy＜10 arc branches, rolling momentum＜0.2 degree; Reductor output accuracy height, the rolling momentum is little.Requirement turbine and worm reducing gear fit clearance is little, precision is high, backlash is minimum, and the gap design of disappearing is arranged, and can eliminate the gap that turbine and worm produces in long-term use by adjusting.
2) under the situation of outage, also can realize launching and collection to satellite antenna; During outage, satellite antenna can launch and collect.This requires machine driving except that automatic adjustment, can also manual adjustment.When momentary power failure, the antenna support arm has auto-lock function.
3) volume is little, and is in light weight, and moment is big.Owing to be portable system, that cube is little, in light weight, moment is big.Need select accurate turbine and worm mechanism for use, use the less motor of moment, by the gearratio amplifying moment.
The utility model content
In order to solve above technical problem, the utility model provides a kind of portable satellite station antenna drive mechanism, one stepping motor is connected with worm-and-wheel gear by shaft coupling, worm-and-wheel gear drives a rotating disk, rotating disk and antenna rotating platform are screwed, and stepping motor also is connected with a manual adjusting handle, and links with stepping motor, the rotation of automatic or manual driven antenna rotating platform, the accurate location of realizing antenna bearingt.
Superior effect of the present utility model is:
1) volume is little, only 150*80*45mm; In light weight, 1Kg only; Moment is big;
2) reductor output accuracy height, the rolling momentum is little;
3) under powering-off state, shake manual adjustment handle rotating stepper motor.
Description of drawings
