Abstract

Réducteur de vitesse pour une turbomachine, telle qu'un turbopropulseur, comprenant des parties tournantes engrenées les unes avec les autres, caractérisé en ce qu'une première partie tournante (16') comprend un pignon (26') à denture hélicoïdale engrenée avec un pignon à denture hélicoïdale d'une seconde partie tournante, ladite première partie tournante étant équipée de moyens (34) de mesure des efforts axiaux auxquels elle est soumise du fait de la transmission d'un couple de rotation par ladite seconde partie tournante, lesdits moyens de mesure étant configurés pour être reliés à des moyens (38) de calcul dudit couple de rotation à partir d'un signal de sortie desdits moyens de mesure.Speed reducer for a turbomachine, such as a turboprop, comprising rotating parts meshed with each other, characterized in that a first rotating part (16 ') comprises a helical-toothed pinion (26') meshed with a helical pinion of a second rotating part, said first rotating part being equipped with means (34) for measuring the axial forces to which it is subjected due to the transmission of a rotational torque by said second rotating part, said means measuring devices being configured to be connected to means (38) for calculating said torque from an output signal from said measuring means.
