面齿轮的超静定支撑对传动扭矩的影响

某反应器转轮由超静定支架支撑，电机经减速器后带动同轴的小齿轮转动，小齿轮和转轮一侧的面齿轮啮合驱动其转动。为了研究和分析面齿轮的传动扭矩和超静定支撑对传动扭矩的影响，对电机的输出扭矩进行了现场测试。通过对测试数据的分析，发现最大的瞬态传动扭矩是因为超静定支撑系统引起的，而且远大于传动扭矩的平均值。在此基础上，提出了后期面齿轮的弯曲和接触强度校核时要考虑到最恶劣的工况，同时建议在后期超静定支撑优化过程中，提高辊子组件的加工精度，改善超静定支撑系统的安装工艺，使各个滚轮的承载情况尽可能接近理想工况，从而降低传动扭矩的瞬态峰值，保证系统能够安全可靠地运行。

Effect of Statically Indeterminate Support on Driving Torque in Face Gear

The runner of a reactor is supported by a statically indeterminate support, the face gear of which is driven by the motor and the reducer. In order to study and analyze the driving torque of the face gear and the effect of the statically indeterminate support on the driving torque, the output torque of the motor was tested on the spot. Through the analysis of the test data. it was found that the maximum transient driving torque was caused by the statically indeterminate support system, and was much higher than the average value of the driving torque. Based on this. the bending and contact strength of the face gear in the worst working condition should be considered. and it was suggested that the machining accuracy of the roller components and the installation technology of the system should be improved in the further statically indeterminate support optimization process, making the load situations of the rollers close to the ideal condition. thus to reduce the transient peak of the driving torque, and to guarantee operating of the system safely and reliably.
