Torque measuring device and method special for differential combination

Abstract

The invention relates to a torque measuring device and method special for a differential combination. The device comprises an upper computer, a driving module, a torque accurate loading module, a torque overload protection module, a torque measuring module, a torque rotating speed sensor in-situ calibration module, a torque transmission module, a high and low temperature environment controller, a supporting frame and an experimental platform. In the calibration process, a standard torque sensor is used for calibrating a torque and rotating speed sensor. In the torque measurement, under the temperature of each point, the measured value of the torque and rotating speed sensor is recorded, and the torque set value and the measured value of the torque and rotating speed sensor are compared, so that the torque output of the butt lock driving combination under the measured point can be obtained, and the test of the differential combination torque performance is completed. According to the invention, the torque and rotating speed sensor can be calibrated without dismounting the torque and rotating speed sensor, and the output torque characteristic of the differential combination can be measured at the high and low temperature of-70 DEG C to 100 DEG C.

Description

technical field [0001] The invention relates to a differential combined torque measuring device, in particular to a differential combined torque measuring device and method. Background technique [0002] The aerospace industry is the most challenging high-tech industry in the world today and can most stimulate the development of related industries. The development of the aerospace industry is a symbol of the country's scientific and technological level, and it is also a strategic measure to enhance the country's economic strength and national defense strength. The successful completion of the rendezvous and docking of Tiangong-1 and Shenzhou-8 marks that my country has entered the space station era. However, there is still a considerable gap between my country's space docking technology and that of the United States and Russia. The ground test and calibration technology of the torque performance of key components of the space docking structure is a very prominent technical ...
