| Abstract: | The setting method of three reference points was proposed by analyzing the structure and cutting motion of the spiral bevel and hypoid gear cutter head.Taking the spiral bevel and hypoid gears with the gear using the generating method and the pinion using the duplex helical method as the research object,a simplified calculation method of the processing parameters for the gear of completing method was proposed.The general meshing rule of spiral bevel and hypoid gears was summarized,an optimization model for the gear cutting control of the pinion was established by combining with the reference points setting method and using the flexible motion control characteristics of the Free-Form machine tool,and a set of optimal machining parameters were obtained. A design software was developed based on the above calculation method,and then based on the domestically-made computer numerical control bevel gear processing equipment,a networked closed-loop manufacturing was carried out with a pair of hypoid gears as an example.The test results showed that the transmission error amplitude was 13.2″,the contact area of the two tooth surfaces was located in the middle of the tooth surface at an inner opposite angle,which verified the correctness of this method,and effectively solved the industry problem of difficulty in synchronous adjustment of the double-sided contact characteristics when the spiral bevel and hypoid gear was processed by the completing method. |
