Abstract

The invention provides a timestamp-based relative torsion angle measuring device. The timestamp-based relative torsion angle measuring device comprises a PLC (Programmable Logic Controller) control module and a rotating speed sensor, and the PLC control module is connected with the rotating speed sensor. According to the invention, a phase difference measurement function integrated in a product can be realized, and the system can be expanded into a control system so as to realize uniform distribution of meshing positions or fixation of meshing positions. The method is simple and reliable, and the precision meets conventional requirements.

Description

technical field [0001] The invention relates to the field of relative torsion angle measurement, in particular to a time stamp-based relative torsion angle measurement device. Background technique [0002] In synchronous clutches and other requirements that require obtaining the relative torsion angle of two rotating shafts, it is necessary to measure the relative torsion angle of the two rotating shafts online in real time, and then integrate it into the product and use it for control purposes, such as evenly distributing the utilization rate of each meshing position to extend service life or fix the meshing position to obtain the best dynamic balance effect, etc. [0003] Currently, such measurement methods use oscilloscopes or computers, which cannot be integrated into products and control systems. Contents of the invention [0004] The object of the present invention is to solve the problem that measuring the relative torsion angle of two rotating shafts cannot be int...
