Cycloid reducer transmission system detection:
With the support of data processing, signal analysis and computer technology, the transmission system uses a dynamic error detection device to measure time domain error information as the starting point. The connotation of the transmission system dynamic test should include the following aspects.
(XNUMX) Dynamic accuracy detection of transmission chain
The excitation of the transmission system includes the periodic excitation caused by the machining and assembly errors of the cycloidal gear, pin wheel, gear, worm gear, worm, screw, shafting, etc. of the transmission parts in the chain, and the torsional vibration of the transmission parts of the transmission chain in operation And shock excitation, as well as random excitation caused by grid fluctuations and transient instability of transmission components.
(XNUMX) Time domain analysis and processing of errors
Using data processing technology, time-domain statistical processing is performed on the error samples. By obtaining the characteristic values of the transmission system in the time domain, the accuracy of the system can be evaluated.Furthermore, the correlation analysis of the system time domain error can determine the nature of the error.
(XNUMX) Frequency domain analysis of error
Using the spectrum analysis technology in signal analysis, the time domain error of the cycloid pinwheel reducer system is transformed into the frequency domain for spectrum analysis, and then the spectrum obtained by the analysis and the transmission parts of the transmission chain are carried out under certain working conditions. By comparison and analysis, the fault location in the chain and the contribution of each transmission component error to the entire chain error can be accurately found, so as to realize the fault diagnosis of the transmission system.
