The axial clearance of double row angular contact ball bearing or double row tapered roller bearing has important effect on bearing performances such as fatigue life, running accuracy, temperature raise and noise etc. 双列角接触球轴承或双列圆锥滚子轴承的轴向游隙对轴承的疲劳寿命、旋转精度、温升和噪声等性能有很大影响。
These undulators all can increase the radiation power with their own parameters optimization, and the square tapered undulator gives the most outstanding effect. However, only the linear taper can improve the radiation spectrum distinctly. 结果表明,这四种波荡器都能在各自参数优化时提高辐射功率,尤其以正向平方锥化的效果最为显著,但是仅有正向线性锥化能够显著改善SASE辐射谱。
Calculates the load distribution in a tapered roller bearing under combined loads, and analyzes the effect of misalignment on the loads in a tapered roller and raceways. 通过计算承受联合载荷的圆锥滚子轴承负荷分布,分析了在不同偏斜状况下圆锥滚子及滚道受力的变化趋势,总结出偏斜对圆锥滚子轴承受力的影响。
Based on the assumption of cross section plane distortion and section reversing linear geometric parameters, we have derived a small tapered four-node spar element stiffness matrix in which web shear deformation effect is included. 本文基于截面变形的平面假设和截面参数的逆线性假设,导出了计算梁腹钣剪切变形的小锥度变截面四节点梁元的刚度矩阵。
