Description
(1)スケールと、このスケールを収納するハウジングと、
前記ハウジング内に収納され前記スケールと対向配置されるとともにこのスケールを走査して位置情報を得るセンサユニットとを有するリニアエンコーダにおいて、
前記ハウジングまたはそのエンドカバーにはスケールとセンサユニットとのギャップに対応する位置にギャップ調整用の調整穴を有するリニアエンコーダ。
(2)前記スケールとセンサユニットとの間に接触部が存在しない上記(1)のリニアエンコーダ。
(3)スケールと、このスケールを収納するハウジングと、前記ハウジング内に収納され前記スケールと対向配置されるとともにこのスケールを走査して位置情報を得るセンサユニットとを有し、前記ハウジングまたはエンドカバーのスケールとセンサユニットとのギャップに対応する位置にギャップ調整用の調整穴を有するリニアエンコーダの調整方法であって、
〔1〕調整穴に装着されたカバーを取り外して調整穴を露出させ、
〔2〕ギャップゲージを前記調整穴からスケールとセンサユニットとの間に挿入し、
〔3〕センサユニットの位置を調整してスケールとセンサユニットとのギャップを調整し、
〔4〕ギャップゲージを取り外して前記カバーを装着する
リニアエンコーダの調整方法。
(4)前記スケールとセンサユニットとの間に接触部が存在しない上記(3)のリニアエンコーダの調整方法。
(1)先ず、図2に示すように調整穴11を封鎖しているカバー10の止めねじ102を取り外し、カバー10を取り外す。
(2)次いで、図3に示すように露出した調整穴11から隙間ゲージ50のゲージ部51を挿入する。この隙間ゲージ50は前部に形成されたゲージ部51の厚さが、必要とされるギャップtに対応した厚さに調整されている。また、ゲージ部51の後部にはツバ52と、さらにその後部に持ち手53が形成されている。ツバ52は、調整穴11の周囲に形成されている段差部12の内周とほぼ同じ大きさに形成され、カバー10同様に段差部内にその一部が収納されることにより、段差部12と係合して調整作業中に自己保持されるようになっている。また、ツバ52により調整穴11が覆われて密封されるので、調整時の外気の影響が極めて少なくなる。
