Abstract

A torque measurement system (50; 150) for an aircraft propulsor (10) including a reduction gearbox (31) includes generally a first toothed wheel (52) mounted to a loaded shaft (54), a second toothed wheel (56) mounted to a torque reference tube (58; 158) radially spaced apart from the loaded shaft (54) and concentric therewith, and a torque probe (20) located proximate the first and second toothed wheels (52, 56). A frustoconical element (60, 62) is located proximate an input end (47) of the loaded shaft (54), the frustoconical element (60, 62) having an annular body (65) radially disposed between the loaded shaft (54) and the torque reference tube (58; 158) and being mounted for rotation with one of the two. The frustoconical element (60, 62) includes a frustoconical surface (61, 63) that abuts a complementary running surface. The frustoconical surface (61, 63) of the frustoconical element (60, 62) and the complementary running surface rotate relative to each other and define a contact interface (90), the contact interface (90) being annular and oriented at an angle (θ) relative to the central axis (11).
