ROTARY JOINT
To provide a rotary joint capable of measuring a rotation angle with high accuracy.SOLUTION: A rotary joint comprises a flange, a cylindrical rotor having one end connected to the flange, a shaft having an outer periphery connected to an inner periphery of the rotor so as to be rotatable about the central axis of the rotor as the rotation axis and having a hole formed along the central axis, a rod having one end connected to the flange and provided in the hole so as to extend from one end side of the shaft along the central axis, an angle measuring unit connected to the hole from the other end side of the shaft toward the other end of the rod and measuring the rotation angle about the central axis between the rod and the shaft as the rotation axis, and a shielding member formed in a cup shape, having an outer periphery connected to the hole so as to be rotatable along the central axis and having the other end of the rod connected to its inner periphery, and shielding between the rod and the angle measuring unit within the hole.SELECTED DRAWING: Figure 2
【課題】高精度で回転角度を測定できる回転継手を提供する。【解決手段】回転継手は、フランジと、一端がフランジに接続される筒状のローターと、ローターの中心軸を回転軸として回転可能にローターの内周に外周が接続され、中心軸に沿うように孔部が形成されているシャフトと、一端がフランジに接続され、シャフトの一端側から中心軸に沿って延在するように孔部内に設けられるロッドと、シャフトの他端側からロッドの他端に向かうように孔部に接続され、ロッド及びシャフトの間の中心軸を回転軸とする回転角度を測定する角度測定部と、カップ状に形成されており、中心軸に沿って回転可能に外周が孔部に接続され、内周にロッドの他端が接続され、孔部内においてロッド及び角度測定部の間を遮蔽する遮蔽部材と、を備える。【選択図】図２
