Abstract

The invention discloses a torque metering device comprising a mounting chamber, a piston which is horizontally slidingly arranged inside the mounting chamber, and a sealed grease oil chamber which is formed by enclosure of the end of a first end of the piston and the mounting chamber. The grease oil chamber communicates with a pipeline which feeds grease oil to the grease oil chamber. The pipeline is provided with a pressure measurement member for measuring the pressure inside the grease oil chamber. The end surface of the first end of the piston is provided with a leakage hole which is used for communicating external oil lines to lead grease oil inside the grease oil chamber flowing to the outside. The device also comprises an intermediate gear which is rotationally arranged and produces axial force in the axial direction during operation, wherein the intermediate gear is arranged on the piston for pushing the connected piston travelling horizontally to squeezing the grease oil inside the grease oil chamber. The pressure measurement member measures the pressure inside the grease oil chamber to obtain the value of torque transmitted by the intermediate gear. By use of the torque metering device for measuring toque, the measuring accuracy is high, the signal response speed is fast, and the reliability is high; and the device has simple structure and is easy to maintain.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a torque metering device. Background technique [0002] In the field of high-precision and high-power transmission, accurate measurement and feedback of dynamic torque is of great significance to the entire power system. The existing torque measurement methods mainly include three categories: balance force method, energy conversion method and transfer method. [0003] The balance force method in the traditional sense is mainly realized by measuring the reaction torque of the body to the main shaft. Due to the slow response of the system, dynamic torque measurement cannot be realized; the energy conversion method uses the law of energy conservation to measure torque by using other parameters such as thermal energy and electric energy. An indirect measurement method, which has high measurement error and is not often used; the transfer method mainly measures the transmitted torque by me...
