この考案は、たとえばアンテナ装置を人工衛星

装置の反射鏡部の回転角度（抑角）を検出する角
度検出装置に関するものである。[Detailed description of the invention] This invention relates to an angle detection device that detects the rotation angle (inhibition angle) of the reflector part of the antenna device in order to accurately point the antenna device in the direction of an artificial satellite, etc. It is.

For example, the detected object 3 is a self-aligning roller held in a predetermined position by a retaining ring 7a fixed to the other end of the cylindrical shaft 2 by a fixing bolt 10a. The bearing 4 is a bearing housing in which the self-aligning roller bearing 3 is held in a predetermined position by a fixing bolt 10b and a retaining ring 7b. There is. Therefore, it goes without saying that the cylindrical shaft 2 is rotatably supported by the self-aligning roller bearing 3 supported by the pedestal 12 via the bearing housing 4. 5 is attached to the cylinder shaft 2 by means of a mounting screw 13.
It is a connecting shaft that is attached concentrically to the shaft end of the shaft and has an angle (inhibition angle) detection gear 6 fixed to one end.

ない欠点がある。 Since the conventional angle detection device is configured as described above, when the cylindrical shaft 2 is rotated in order to orient the detected object 1 of the antenna device in the direction of artificial hygiene, etc., both ends of the cylindrical shaft 2 There is a self-aligning roller bearing 3 between the angle detection gear 6 of the detected object 1 attached to each section, and there is a considerable distance between the detected object 1 and the angle detection gear 6, so when the cylinder shaft 2 rotates, the detected object 1 and the angle detection gear 6, the cylinder shaft 2 is twisted due to the frictional resistance of the self-aligning roller bearing 3, and the rotation angle of the detected object 1 and the rotation angle of the angle detection gear 6 are A torsional displacement inevitably occurs, and there is a drawback that the angle of the detected object 1 cannot be accurately detected by the angle detection gear 6.

つても限度があり、確実な筒軸２のねじれ変位防
止対策とはいえない。 To deal with this, in order to prevent torsional displacement of the cylinder shaft 2, the diameter of the cylinder shaft 2 is increased, and self-aligning roller bearings 3 with low frictional resistance are used. If the cylindrical shaft 2 becomes thicker, not only will each component of the antenna device related to it become larger, but it will also lead to an increase in cost, and there are limits to the self-aligning roller bearing 3, which has low frictional resistance. This cannot be said to be a reliable measure to prevent torsional displacement of the cylinder shaft 2.

ある。 This invention was made with attention to this point, and includes a connecting shaft 5 which is inserted through a gap into a cylindrical shaft 2 to which a detected object 1 is fixed at one end, and has an angle detection gear 6 attached to its protruding end. The other end is fixed to the detected object side of the cylindrical shaft 2 so that no torsional displacement occurs in the connecting shaft 5 when the cylindrical shaft 2 rotates, and the angle of the detected object 1 is always accurately detected. The present invention aims to provide an angle detection device that can perform the following functions.

着されている。 That is, FIG. 4 is a longitudinal sectional view showing an embodiment of this invention, in which 1 is a detected object such as a reflector of an antenna device A fixed to one end of a rotatable cylinder shaft 2, and 9 and 8 are objects to be detected. A fixing bolt 1 is attached to the other end of the cylinder shaft 2.
A spherical bearing 4 is held in a predetermined position by a retainer ring 7a fixed by a retainer ring 7a, and supports the cylinder shaft 2 in a deflectable and rotatable manner.
The bearing housing 4 is held in a predetermined position by a fixing bolt 10b and a retaining ring 7b, and this bearing housing 4 is fixed to the upper end of a tower-shaped pedestal 12. Therefore, it goes without saying that the cylindrical shaft 2 is deflectably and rotatably supported by spherical bearings 9 and 8 supported by the pedestal 12 via the bearing housing 4. Reference numeral 5 denotes a connecting shaft which is inserted into the cylindrical shaft 2 through a gap and whose inner end flange 5a is fixed to the cylindrical shaft 2 at the same location as the detected object 1 with a fixing bolt 10c. An angle detection gear 6 is fixed to the outer end of the gear 6 as in the conventional case.

る優れた効果を有するものである。 As described above, the angle detecting device of this invention has the object to be detected 1 fixed at one end, and the other end is inserted through a gap into the cylindrical shaft 2, which is supported by a mount so as to be deflectable and rotatable through a spherical bearing. Angle detection gear 6 on the protruding end
A connecting shaft 5 is provided, and the other end of the connecting shaft 5 is fixed to the side of the detected object 1 of the cylindrical shaft 2, so that the detected object 1 and the angle detection gear 6 can be connected to each other as in the conventional case. Even though there was a distance between the
This has an excellent effect in that the angular change of the object to be detected can be detected with high accuracy without causing any torsional displacement.
