摘要

输出主轴是某石油钻机的关键部件之一,其可靠性直接影响着石油钻机的使用寿命与经济成本。运用有限元方法对原输出主轴的结构进行了应力分析,发现在某些位置出现较大的应力集中现象;提出优化改进方案,并对改进前后的输出主轴进行对比分析,根据分析结果确定了输出主轴最终的改进方案,结果表明:改进后的输出主轴安全系数显著提高,并运用有限元方法对该输出主轴进行了模态分析,验证了输出主轴的工作转速在安全范围内。本研究对提高石油钻机输出主轴使用性能方面有一定的指导意义。

Abstract

The output shaft is one of the core components of the gearbox of an oil rig,The reliability of the output shaft directly affects the service life and economic benefit of the oil rig. In this paper,the stress analysis of the structure of the original output shaft is carried out by using the finite element method; The optimization and improvement scheme is put forward,and the stress of the output spindle before and after the improvement is compared and analyzed,According to the analysis results,the final improvement scheme of the output shaft is determined,The results show that the safety factor of the improved output shaft is significantly improved,The modal of the output shaft is analyzed by finite element method,It is verified that the working speed of the output shaft is within the safe range. The research in this paper has certain guiding significance to improve the performance of oil rig output shaft.
