Abstract：[Objective]Aiming at the problem of thermal characteristics of dry gear hobbing machines,the research on multi-source information fusion test and analysis was carried out.[Methods]Based on the analysis of the structure layout and the law of multi-source heat generation and heat dissipation of the dry gear hobbing machine,the testing scheme of its thermal characteristics was established.Through the selection of hardware for the lower computer,the development of software functions for the upper computer,and the integration of test functions,the multi-source information fusion test method for the thermal characteristics of dry gear hobbing machine was constructed.Based on the input-process-output(IPO)model,the sequential processing method of multi-source thermal data of dry gear hobbing machine was put forward.Using outlier replacement,moving average filtering,wavelet filtering,and data resampling,the accurate analysis of multi-source thermal data was realized.The dry roll-cutting machining test of an automotive gear was used for verification and analysis.[Results]The results show that the proposed testing and analysis method has high validity and reliability.The on-line measurement and accurate analysis of the thermal characteristics of the dry hobbing machine are realized,which can provide support for the thermal balance design of the dry gear hobbing machine.
