Title (EN) INSTRUMENTED SPINDLE OR LOAD CELL FOR HIGH LOAD, HIGH RESOLUTION
(FR) TIGE INSTRUMENTÉE OU CELLULE DE CHARGE POUR CHARGE ÉLEVÉE, À HAUTE RÉSOLUTION
Abstract:
(EN) An assembly operable for measuring one of a force and a moment, comprising: a compliant flexure mechanism that is one of deflected and deformed under an applied load; a low resolution load sensor coupled to the compliant flexure mechanism and operable for measuring one of the deflection and the deformation of the compliant flexure mechanism under a relatively higher load; and a high resolution load sensor coupled to the compliant flexure mechanism and operable for measuring one of the deflection and the deformation of the compliant flexure mechanism under a relatively lower load; wherein the high resolution load sensor is one of a non-contact sensor that is disposed at a distance from the compliant flexure mechanism and a contact sensor that is not subject to damage by the relatively higher load. Optionally, the low resolution load sensor is disposed adjacent to a narrowed neck portion of the compliant flexure mechanism.
(FR) La présente invention concerne un ensemble opérationnel pour mesurer l’un parmi une force et un moment, comprenant : un mécanisme de flexion souple qui est dévié ou déformé sous une charge appliquée ; un capteur de charge à basse résolution couplé au mécanisme de flexion souple et opérationnel pour mesurer l’un parmi la déviation et la déformation du mécanisme de flexion souple sous une charge relativement plus élevée ; et un capteur de charge à haute résolution couplé au mécanisme de flexion souple et opérationnel pour mesurer l’un parmi la déviation et la déformation du mécanisme de flexion souple sous une charge relativement plus faible ; dans lequel le capteur de charge à haute résolution est l’un parmi un capteur sans contact qui est disposé à une distance du mécanisme de flexion souple et un capteur à contact qui n’est pas susceptible d’être endommagé par la charge relativement plus élevée. Facultativement, le capteur de charge à basse résolution est disposé en position adjacente à une partie de col plus étroite du mécanisme de flexion souple.
