Gathering And Analyzing The Error Signal On-machine Measuring The Accuracy Of Large Gears

This paper describes the machining precision gear and the development of measurement at home and abroad, Analysis of the necessity and urgency. In accordance with the new national standards for gear, For the deviation of the three projects, Thesis carried out the error theory and technology research, for difficulties and characteristics, based on the measurement principle, Identified the guiding ideology, the key technology and technical route, on the basis of the program, Carries out software design research.This article puts forward the overall program design, relying on a hobbing, Creatively uses measurement programs of rack-shaped blade edge probe. Analyzes the tooth profile error and bias of the helix measuring principle,designs the entire measurement system, carries out the distribution of hardware and software features and design,Interface design,Anti-jamming system design,and so on.This article focuses on the connections of mechanical parts,Detection system design,error signal acquisition.Aims at real-time,using assembly language and C language,completes the error signal acquisition and analysis.To achieve high efficiency,VB6.0 is used to prepare to operating system interface.the field application has shown that the principle is correct and the technology is feasible.The locale experiment of the instrument on-machine measuring large gears is to be carried out,to prove that the principle is correct and the measurement technique is feasible.
