Description

A kind of satellite antenna rotating mechanism
Technical field
The utility model relates to a kind of satellite antenna rotating mechanism, belongs to satellite antenna field.
Background technology
Satellite antenna reflection surface is general all heavier, so the rotation axis of satellite antenna is easy to situations such as shaking after a long time use, and the static(al) formula that traditional satellite antenna rotation axis all adopts screw-nut to coordinate is fixed, screw-nut is difficult to take off after getting rusty, and adds the degree of difficulty of maintenance.
Utility model content
The technical problems to be solved in the utility model is: the technical problem overcoming prior art Satellite antenna rotation mechanism instability, provides a kind of novel satellite antenna rotating mechanism.
The utility model solves the technical scheme that its technical problem adopts:
A kind of satellite antenna rotating mechanism, comprise cursor A, cursor B and rotating shaft, the turning end A of described cursor A is provided with rotation slot A, the turning end B of cursor B is arranged in rotation slot A, is provided with groove B in described turning end B;
Described rotation axis is through turning end A and turning end B, the two ends of described rotation axis are provided with hold-down nut, two end in contact of described hold-down nut and turning end A, rotation fixed mechanism is provided with in described groove B, described rotation fixed mechanism comprises spacing collar, guide vane end stop A, guide vane end stop B, spring and piezoelectric ceramic, described guide vane end stop A is fixed in rotating shaft, described spacing collar is semiclosed cylinder, spring is provided with between described spacing collar blind end and guide vane end stop A, the openend of described spacing collar pushes up and is pressed on one of them side of groove B under the driving of spring, described guide vane end stop B is arranged on spacing collar inside, piezoelectric ceramic is provided with between the blind end of described spacing collar and guide vane end stop B, described guide vane end stop B is fixed in rotating shaft.
As further innovation of the present utility model, the openend of described spacing collar is provided with some raised tooth, a side wall surface of described groove B relative limit sleeve openings end is provided with the groove corresponding with described raised tooth.
The beneficial effects of the utility model are:
The utility model is by the cooperation of piezoelectric ceramic and spring, when fixing, spacing collar pushes up and is pressed on cursor B under the driving of spring, realize the fixing of cursor A and cursor B, when needs rotate, electric current is applied to piezoelectric ceramic, piezoelectric ceramic expands promotion spacing collar, spacing collar and cursor B are got loose, make can freely rotate between cursor A and cursor B, if simultaneously between rotating mechanism pressurized excessive, when spacing collar is subjected to displacement, the electric current that piezoelectric ceramic produces can change, and can realize detection at any time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is generalized section of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the utility model is a kind of satellite antenna rotating mechanism, comprises cursor A2, cursor B3 and rotating shaft 4, the turning end A of cursor A2 is provided with rotation slot A, the turning end B of cursor B3 is arranged in rotation slot A, is provided with groove B in turning end B;
Rotation axis is through turning end A and turning end B, the two ends of rotation axis are provided with hold-down nut 1, two end in contact of hold-down nut 1 and turning end A, rotation fixed mechanism is provided with in groove B, rotate fixed mechanism and comprise spacing collar 7, guide vane end stop A5, guide vane end stop B9, spring 6 and piezoelectric ceramic 8, guide vane end stop A5 is fixed in rotating shaft 4, spacing collar 7 is semiclosed cylinder, spring 6 is provided with between spacing collar 7 blind end and guide vane end stop A5, the openend of spacing collar 7 pushes up and is pressed on one of them side of groove B under the driving of spring 6, it is inner that guide vane end stop B9 is arranged on spacing collar 7, piezoelectric ceramic 8 is provided with between the blind end of spacing collar 7 and guide vane end stop B9, guide vane end stop B9 is fixed in rotating shaft 4.
The openend of spacing collar 7 is provided with some raised tooth, a side wall surface of groove B relative limit sleeve 7 openend is provided with the groove corresponding with raised tooth.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
