摘要
圆锥滚子轴承对于重载旋转机械的静动态性能有着重要的影响,空心滚子轴承正在逐渐被用于重要的工程实际中。基于Hertz接触理论和有限元方法,运用ANSYS分别建立了实心和空心圆锥滚子轴承的单滚子-套圈等效三维仿真模型,对比分析不同空心率和载荷等参数对实心和空心圆锥滚子轴承的弹性变形和接触应力等的影响规律,运用理论计算值验证了圆锥滚子轴承的接触应力值。分析结果为圆锥滚子轴承的优化设计和工程应用提供了参考依据。
The tapered roller bearing has great influence on rotary machine with high load, and hollow roller bearing is applied in significant engineering right now. According to Hertz contact theory and FEM, the equivalent three-- dimensional simulation model of single roller--ring solid and hollow tapered roller bearing is established in ANSYS separately, the influence rule of various hole rate and load on elastic deformation and contact stress etc is analyzed. As a result, contact stress value is verified by theoretical calculating result. Simultaneously, the analysis one affords reference for optimal design and engineering application of tapered roller bearing.
