Abstract
(EN)
Disclosed is an angle detecting device with auto-correct function comprising an axial deviation measurement function, allowing a variety of setups to be carried out with ease upon such as engines and vehicle drive shafts. An angle detecting device with auto-correct function is used wherein an auto-correct value is found by arranging a plurality of sensor heads equiangularly upon the perimeter of a dial that is anchored upon a rotational axis, choosing one of the sensor heads to serve as a reference sensor head, finding the sum of the measurement deviations between the reference sensor head and each of the other sensor heads, and taking the average measurement deviation by dividing the sum of the measurement deviations by the number of sensor heads. The sensor head that is chosen to be the reference sensor head is changed in sequence, auto-correct values are found for all sensor heads serving as the reference head, each respective auto-correct value is offset by the angle of positioning with respect to a specified sensor head, and phase alignments are made with the auto-correct value when the specified sensor head is treated as the reference head. The average is taken for all of the phase transformed computation results, the average thus taken is subtracted from the respective phase transformed computation results, and only the asynchronous angular error is abstracted.

L'invention concerne un dispositif de détection d'angle pourvu d'une fonction d'autocorrection comprenant une fonction de mesure de la déviation axiale, qui permet de mettre en œuvre facilement divers réglages, par exemple sur des moteurs et des arbres d'entraînement de véhicule. Le procédé d'utilisation du dispositif de détection d'angle comportant une fonction d'autocorrection comporte les étapes consistant à : obtenir une valeur d'autocorrection par l'aménagement d'une pluralité de têtes de détection de manière équiangulaire sur le périmètre d'un cadran qui est fixé sur un axe de rotation, choisir une des têtes de détection pour servir de tête de détection de référence, calculer la somme des déviations de mesure entre la tête de détection de référence et chacune des autres têtes de détection et calculer la déviation de mesure moyenne en divisant la somme des déviations de mesure par le nombre de têtes de détection ; changer séquentiellement la tête de détection qui est choisie comme tête de détection de référence, obtenir des valeurs d'autocorrection pour toutes les têtes de détection servant de tête de détection de référence, décaler chaque valeur d'autocorrection respective selon l'angle de positionnement par rapport à une tête de détection spécifiée et effectuer des alignements de phase à l'aide de la valeur d'autocorrection quand la tête de détection spécifiée est considérée comme tête de référence ; faire la moyenne de tous les résultats de calcul comportant une transformation de phase est effectuée, soustraire cette moyenne des résultats de calcul respectifs comportant une transformation de phase, et n'extraire que l'erreur angulaire asynchrone.

 自己校正機能付き角度検出器に軸ぶれ計測機能をも具備させ、エンジン、自動車のドライブシャフト等への各種セットアップも簡単に行えるようにする。 回転軸に固定した目盛り盤の周囲に等角度間隔に複数のセンサヘッドを配設し、該センサヘッドの一つを基準センサヘッドとして選択したとき、この基準センサヘッドと他のセンサヘッドのそれぞれとの計測差の和を求め、この和を前記センサヘッドの個数で除して平均値を得ることにより自己校正値を求めようにした自己校正機能付き角度検出器を利用する。そして、基準センサヘッドとして選択するセンサヘッドを順次他のセンサヘッドに変更し、すべてのセンサヘッドについて、これを基準ヘッドとした場合の自己校正値をそれぞれ求め、各自己校正値を、特定のセンサヘッドとの配置上の角度分だけずらして、特定のセンサヘッドを基準ヘッドとした場合の自己校正値に位相を合わせる。位相変換したそれぞれの演算結果のすべてについての平均値を求め、位相変換したそれぞれの演算結果から、この平均値を減算し、非同期角度誤差のみを取り出す。
