Description

technical field [0001] The invention belongs to the technical field of rotating machinery detection, and in particular relates to a torque change measuring device and method for detecting rotating machinery during operation. Background technique [0002] At present, the status monitoring of equipment in the production process has become a trend, especially the continuous production equipment of iron and steel enterprises has huge losses due to sudden accidents. As the contradiction between the upgrading of iron and steel products and the aging of equipment becomes more and more prominent, it is even more necessary to monitor its operation. [0003] Existing rotating machines generally include motors, rotating shafts, couplings, gearboxes, loads, etc. Torque transmission is performed between the various parts of the rotating machines, thereby closely linking them together. During the operation of rotating machinery, due to changes in the state of the equipment itself and chan...
