摘要：【中文】本发明公开的齿轮传动系统的工作转速设置方法及系统，通过建立齿轮轮体的超单元模型，并将超单元模型与构建的轴单元模型、轴承模型、齿轮啮合模型构建出精度更高的齿轮传动模型，通过齿轮传动模型求解出齿轮传动系统的固有频率，并根据固有频率设置齿轮传动系统的工作转速。由于该齿轮传动模型相对于现有的齿轮集中质量模型精度更高，用该齿轮传动模型求解出的齿轮传动系统的固有频率精度更高，因而根据精度更高的模型求解出的固有频率的精度更加准确，根据固有频率设置齿轮的工作转速更能避免齿轮的共振的发生，提高齿轮工作的安全性，进而解决现有根据精度不高的固有频率设置的工作转速并未避免实际的工作频率，造成齿轮产生共振的技术问题。 【EN】The invention discloses a method and a system for setting the working rotating speed of a gear transmission system. Because the gear transmission model has higher precision compared with the existing gear concentrated quality model, and the natural frequency precision of the gear transmission system solved by the gear transmission model is higher, the precision of the natural frequency solved according to the model with higher precision is more accurate, the resonance of the gear can be avoided by setting the working rotating speed of the gear according to the natural frequency, the safety of the gear working is improved, and the technical problem that the actual working frequency is not avoided by the existing working rotating speed set according to the natural frequency with low precision, so that the gear generates resonance is solved.
