Intelligent Transformation Of Gear Double-sided Meshing Instrument And Domestic Development Of Measurement And Control System

Gears are widely used in aerospace,automobile,mechanical equipment and other fields.As a basic transmission component,its factory quality is the key to the smooth operation of the equipment and one of the decisive factors to ensure the life of the equipment.In addition,in the’ the 14 th Five-Year Plan’ market supervision modernization plan,it is pointed out that promoting the localization of inspection and testing equipment has become one of the important strategic factors for China to develop a powerful country with science and technology.In this paper,the Haerbin 3101 B gear double-sided meshing comprehensive measuring instrument is taken as the research object,and its intelligent transformation is carried out.At the same time,the localization of the instrument is realized.The intelligent transformation scheme of the gear double-sided meshing comprehensive measuring instrument is expounded,and a measurement system of the domestic intelligent gear double-sided meshing instrument is developed.The main research work of this paper is as follows :Firstly,the detection parameters of the intelligent gear double-sided meshing instrument are analyzed,and the Haerbin 3101 B gear double-sided meshing instrument is reformed.A measurement method of gear multi-dimensional error is designed,and the gear is detected by radial and tooth direction.Based on the motion theory of cam and push rod,the eccentric sleeve and laser displacement sensor are used to replace the cam and push rod,respectively.Combined with the excitation motor,a system with high precision of 16000 lines and resolution of 0.0225° is formed.At the same time,when the gear is engaged on both sides,the radial error data are included in the displacement trajectory of the eccentric wheel,and the radial error data of the gear can be obtained from the displacement trajectory.Secondly,an intelligent measurement and control system of meshing instrument based on Linux RT of X86 architecture platform is developed to realize the localization of the measurement and control system of gear double-sided meshing instrument.The cursor following function is designed to quickly locate the fault tooth.Through EEMD decomposition,the obtained data are analyzed and processed quickly and accurately,and the parameters such as radial comprehensive total deviation and one tooth radial comprehensive deviation are obtained.The program is transplanted into Linux RT based on X86 architecture platform to get rid of the limitation of Windows system and ensure the smooth operation of equipment without shut down for a long time,so as to realize the localization of measurement and control system.Finally,the feasibility and accuracy of each function of instantaneous phase and measurement and control system are verified.The functions of cursor tracking and EEMD data decomposition are tested in Linux RT system,and the results show that the functions can be accurately run.At the same time,through comparative tests and multiple tests,the measurement results of the intelligent modified meshing instrument are compared,and the Pearson correlation coefficient is used to determine.The results show that the modified intelligent meshing instrument has good accuracy and reliability.Figure [39] Table [3] Reference [64]...
