Abstract

The invention provides a shaft torque measuring system based on the Malus's law. A black box detachably sleeves a shaft to be measured; a closed and lightproof space is formed in the box and serves asa measuring area, and a measuring device in the shaft torque measuring system is arranged in the measuring area. According to the structure, a first connecting lantern ring sleeves a supporting platform of the shaft to be measured and overhangs outside the shaft to be measured, a laser, a first light-transmitting element and a light intensity detection element are arranged on the supporting platform separately and successively from front to back of the shaft to be measured and are separated from the radial direction of the shaft to be measured, and a second light-transmitting element is supported by a second connecting lantern ring which detachably sleeves the shaft to be measured, overhangs outside the shaft to be measured, and is positioned between the first light-transmitting element and the light intensity detection element along the axial direction; and a wireless transmission data module and an output module and a display module electrically connected with a processor are also included. The problem that the present torque measurement technology is low in resolution and sensitivity and high in installation difficulty is solved.

Description

technical field [0001] The invention relates to the technical field of shaft torque measurement, in particular to a shaft torque measurement system and a measurement method based on Malus' law. Background technique [0002] Torque is a very important physical quantity in the field of mechanical transmission, which can reflect the operation status of the entire mechanical system and is one of the typical parameters to ensure the stable operation of the transmission system. The measurement and analysis of torque is also an important means to ensure the normal operation of various production equipment and auxiliary equipment, reduce energy consumption and improve efficiency. Therefore, it is necessary to improve the accuracy of torque measurement, the real-time performance of torque monitoring and control, and the reliability of torque abnormality analysis. Safety will inevitably reduce the occurrence of accidents and improve the utilization rate of production equipment. In ot...
