Title
(EN) TORQUE APPLICATION TOOL
(FR) OUTIL D'APPLICATION DE COUPLE
Abstract
(EN)
A torque tool (2) for applying torque to a workpiece is disclosed. A drive shaft (26) is connected to a first component with a rotatable output (32) such that rotation of the drive shaft (26) rotates the rotatable output (32) and a second component is fixedly arranged relative to the first component. A beam transducer (22) extends lengthwise axially and is coupled to the two components. The first component is arranged such that a reaction force experienced by the rotatable output (32) tends to turn the first component relative to the second component. The transducer beam (22) resists which causes it to bend. A bending measurement means or sub-system is then used to measure the degree to which the beam transducer (22) bends.
(FR)
Outil de couple (2) pour appliquer un couple à une pièce. Un arbre d'entraînement (26) est relié à un premier composant avec une sortie rotative (32) de telle sorte que la rotation de l'arbre d'entraînement (26) fait tourner la sortie rotative (32) et un second composant est agencé à demeure par rapport au premier composant. Un transducteur à faisceau (22) s'étend axialement dans le sens de la longueur et est couplé aux deux composants. Le premier composant est agencé de telle sorte qu'une force de réaction subie par la sortie rotative (32) tend à tourner le premier composant par rapport au second composant. Le transducteur à faisceau (22) résiste à la flexion. Un moyen ou sous-système de mesure de flexion est ensuite utilisé pour mesurer le degré auquel le transducteur à faisceau (22) fléchit.
