| 摘 要： | 从赫兹接触理论出发,推导了回转窑托轮歪斜时,滚圈和托轮最大接触应力比与托轮歪斜角度的关系;通过实例分析,给出回转窑托轮歪斜范围内最大接触应力比的列表;得出了回转窑托轮小角度歪斜,最大接触应力显著增加,便可能造成安全事故的结论.为回转窑的设计、运行状态分析、调整提供依据.图4,表1,参10.

| Abstract: | The relation between the maximum contact stress ratio and deflection angle is derived from Hertz contact theory when the deflection of rotary kiln supporting wheel happens. According to the analysis of practical example, the maximum contact stress ratio within the deflection range of rotary kiln supporting wheel is listed. The contact stress will increase largely when the rotary kiln supporting wheel deflects with little angle, which probably will result in accidents correlating to safety. This will provide theory conference for the design, the operating condition analysis and adjusting of the rotary kiln.4tifs.,1tab.,10refs. |
