Description
【０００１】[0001]
本考案はアンテナの仰角系駆動装置に関し、特に仰角回転軸まわりのバランス 調整用カウンタウエイト機構を有しない衛星通信用アンテナの仰角系駆動装置に 関する。 The present invention relates to an elevation system driver for an antenna, and more particularly to an elevation system drive device for a satellite communication antenna that does not have a counterweight mechanism for adjusting balance around an elevation rotation axis.
【０００２】[0002]
従来、この種のアンテナの仰角系駆動装置は、図２に示すように、アンテナ本 体６を仰角回転軸５およびジャッキ駆動機構４によって支持し、ジャッキ駆動機 構４を駆動することによって、仰角回転軸５を中心にしてアンテナ本体６の仰角 を可変している。 2. Description of the Related Art Conventionally, as shown in FIG. 2, an elevation angle drive device for an antenna of this type conventionally supports an antenna body 6 by an elevation angle rotation shaft 5 and a jack drive mechanism 4, and drives the jack drive mechanism 4 to increase the elevation angle. The elevation angle of the antenna body 6 is varied around the rotation axis 5.
【０００３】[0003]
上述した従来のアンテナの仰角系駆動装置では、仰角回転軸まわりのバランス 調整用カウンタウエイト機構を有していないので、アンテナの自重およびアンテ ナに加わる風圧重等の全ての荷重が、仰角回転軸５およびジャッキ駆動機構４に 負荷されることになる。 Since the conventional antenna elevation drive system described above does not have a counterweight mechanism for adjusting the balance around the rotation axis of the elevation angle, all weights such as the weight of the antenna itself and wind pressure applied to the antenna, etc. 5 and the jack drive mechanism 4 will be loaded.
【０００４】 しかし、ジャッキ駆動機構４は、アンテナを常に通信衛星の方向に追尾させる ために高精度が要求されるが、大きな荷重に対して精度および強度を同時に満足 させることが技術的に困難であるという問題点がある。However, the jack drive mechanism 4 is required to have high precision in order to always track the antenna in the direction of the communication satellite, but it is technically difficult to satisfy both precision and strength for a large load at the same time. There is a problem.
【０００５】 本考案の目的は、ジャッキ駆動機構への荷重を軽減して高精度の仰角駆動を可 能とするアンテナの仰角系駆動装置を提供することにある。An object of the present invention is to provide an elevation angle drive device for an antenna, which reduces the load on the jack drive mechanism and enables highly accurate elevation angle drive.
【０００６】[0006]
本考案のアンテナの仰角系駆動装置は、アンテナ本体を支持する仰角回転軸と 、前記アンテナ本体を前記仰角回転軸を中心に微細に回転させる駆動手段とを備 えたアンテナの仰角系駆動装置において；一方端が前記アンテナ本体に固定され たシャフトを駆動して前記アンテナ本体を前記仰角回転軸を中心に大きく回転さ せるシャフト駆動部と、前記シャフトの前記一方端側に設けられて軸方向に縮小 する弾性体からなる緩衝部とを具備し；前記シャフト駆動部を動作させるときは 前記駆動手段は解放状態とし、その後、前記シャフト駆動部を停止して前記シャ フトを固定した後、前記駆動手段を動作させるように構成する。 An elevation angle drive device for an antenna according to the present invention is an elevation angle drive device for an antenna, comprising: an elevation angle rotation shaft for supporting an antenna body; and a driving means for finely rotating the antenna body about the elevation angle rotation axis. A shaft drive unit that drives a shaft, one end of which is fixed to the antenna body, to rotate the antenna body largely around the elevation angle rotation axis; and a shaft drive unit that is provided on the one end side of the shaft and reduces in the axial direction. A shock-absorbing part made of an elastic body; when the shaft drive part is operated, the drive means is released, and then the shaft drive part is stopped to fix the shaft, and then the drive means. Are configured to operate.
【０００７】[0007]
次に本考案について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.
【０００８】 図１は本考案の一実施例を示す側面図である。図２に示した従来の装置と相違 するところは、アンテナの仰角を大きく変化させると共に、アンテナの荷重を分 担するシャフト駆動機構が設けられたことである。FIG. 1 is a side view showing an embodiment of the present invention. The difference from the conventional device shown in FIG. 2 is that a shaft drive mechanism is provided which changes the elevation angle of the antenna largely and also bears the load of the antenna.
【０００９】 このシャフト駆動機構は、アンテナの仰角を変化させるためにシャフト２を駆 動するシャフト駆動部１、およびアンテナ本体６が仰角回転軸５を中心に前方向 に倒れようとする荷重に相当する力でアンテナ本体を後方向に引き戻す弾性体か らなる緩衝部３を有している。This shaft drive mechanism corresponds to a load in which the shaft drive unit 1 that drives the shaft 2 to change the elevation angle of the antenna and the antenna body 6 tend to fall forward around the elevation angle rotation axis 5. It has a buffer portion 3 made of an elastic body that pulls back the antenna body in the backward direction by the force.
【００１０】 さて、アンテナ仰角を大きく変化させて通信衛星の方向にアンテナ本体６を向 ける場合は、シャフト駆動部１の歯車を回転させてシャフト２を駆動する。この 場合、ジャッキ駆動機構４は解放状態とする。その後、アンテナが所定の仰角と なったときにシャフト駆動部１の内部ブレーキにより固定し、ジャッキ駆動機構 ４を動作状態として通信衛星を追尾させる。When the antenna elevation angle is largely changed and the antenna main body 6 is directed toward the communication satellite, the gear of the shaft drive unit 1 is rotated to drive the shaft 2. In this case, the jack drive mechanism 4 is in the released state. After that, when the antenna reaches a predetermined elevation angle, it is fixed by the internal brake of the shaft drive unit 1 and the jack drive mechanism 4 is put into an operating state to track the communication satellite.
【００１１】 ジャッキ駆動機構４が通信衛星を追尾している状態では、ジャッキ駆動機構４ による伸縮は５０ｍｍ程度と僅かであり、この伸縮は、ばね等の弾性体からなる 緩衝部３によって吸収させる。また、この状態のとき、アンテナの自重およびア ンテナに加わる風圧重等の荷重は、仰角回転軸５およびシャフト駆動機構に負荷 されるので、ジャッキ駆動機構４への荷重は軽減する。When the jack drive mechanism 4 is tracking the communication satellite, the expansion and contraction by the jack drive mechanism 4 is as small as about 50 mm, and this expansion and contraction is absorbed by the buffer portion 3 made of an elastic body such as a spring. Further, in this state, the weight of the antenna and the wind pressure applied to the antenna are applied to the elevation rotation shaft 5 and the shaft drive mechanism, so that the load on the jack drive mechanism 4 is reduced.
【００１２】[0012]
以上説明したように本考案によれば、アンテナ本体を仰角回転軸を中心に微細 に回転させる駆動機構の他に、アンテナ本体の仰角を大きく可変させるシャフト 駆動部、およびシャフトの軸方向に縮小する弾性体からなる緩衝部を設け、アン テナ仰角を大きく変化させて通信衛星の方向にアンテナを向ける場合は、シャフ ト駆動部によりシャフトを駆動し、その後、アンテナが所定の仰角となったとき にシャフトを固定し、他方の駆動機構を動作状態として通信衛星を追尾させるこ とにより、アンテナの自重およびアンテナに加わる風圧重等の荷重は、仰角回転 軸およびシャフト駆動機構に負荷されるので、ジャッキ駆動機構への荷重を軽減 でき、高精度の仰角駆動が可能となる。 As described above, according to the present invention, in addition to the drive mechanism for finely rotating the antenna main body about the elevation angle rotation axis, the shaft drive unit for greatly changing the elevation angle of the antenna main body and the reduction in the axial direction of the shaft are provided. When a buffer section consisting of an elastic body is provided and the antenna elevation angle is changed greatly and the antenna is directed toward the communication satellite, the shaft is driven by the shaft drive section, and then when the antenna reaches a predetermined elevation angle. By fixing the shaft and keeping the other drive mechanism in operation to track the communication satellite, the weight of the antenna and the load such as wind pressure applied to the antenna are applied to the elevation rotation shaft and the shaft drive mechanism. The load on the drive mechanism can be reduced and high-precision elevation angle drive becomes possible.
