Abstract

The invention relates to an engine output torque measuring device which is particularly suitable for a small-size gas turbine engine. A torque piston is arranged at the front end of an intermediate gear shaft of the engine, a torque piston contact force-measuring device is arranged in front of the torque piston and comprises a compression ring and a sliding resistor, and a sliding sheet is driven to slide on a sliding bar of the sliding resistor when the outer side of the compression ring is in compression; when the compression ring is not in compression, an elastic part pushes the compressing ring to move to a free end of the sliding bar of the sliding resistor; when the engine outputs shaft power, the front end of the torque piston presses against the outer side of the compression ring and pushes the compression ring to move; and the sliding resistor, an external power source and an ampere meter form a loop. According to the torque measuring device provided by the invention, current is directly measured to obtain an axial force of a gear train and an engine output torque is indirectly measured based on the axial force, thereby improving the response speed of torque measurement; moreover, because measurement errors are only influenced by elasticity coefficients of a spring pack and voltage stability of a power source, measurement precision and reliability are high.

Description

technical field [0001] The invention relates to an engine output torque measuring device, in particular to a device for measuring the engine output torque in real time by measuring the axial force of a gear shaft, which is applied to a small gas turbine engine mainly outputting shaft power. Background technique [0002] For gas turbine engines that mainly output shaft power, such as gas turbines, turboshaft engines, and turboprop engines, real-time measurement of their output torque is a necessary monitoring method. On the one hand, it can monitor the load state of the engine to provide evidence for the operator; on the other hand, when the engine output torque is too large, take necessary measures to ensure that the engine shafting does not cause accidents due to overload. [0003] Accurate measurement of gas turbine engine output shafts remains a challenging problem at present. Existing torque measuring devices for gas turbine engines mostly measure the output torque of t...
