Abstract
Torque measuring devices are provided for measuring the torque being transmitted from a turbo jet engine to auxiliary assemblies such as aircraft air conditioning equipment, auxiliary electrical generator, special lifting devices and the like. The torque measuring device includes a plurality of hollow shafts which are rotatable about a common axis. A first of the shafts is drivingly connected with the engine while a second of the shafts is in driving engagement with an auxiliary assembly. A third elastically deformable shaft is drivingly interposed between the first and second shafts in such a manner that the amount of torque being transmitted results in a relative rotation of the first and second shafts, which relative rotation is detected by electro-magnetic sensors. A toothed arrangement is provided for directly coupling the first and second shafts in response to a predetermined torque which results in relative rotation of the first and second shafts to close a gap between the teeth at this last-mentioned gear tooth arrangement. The first shaft is also provided with an intentional rated breaking point to accommodate shearing thereof in response to excessive torque transfer, whereby the drive train between the turbo jet engine and the auxiliary equipment is interrupted.
