【摘要】 本文在参考国内外有关陶瓷轴承研究文献的基础上，运用Hertz空间接触理论和钢轴承的设计理论，对型号为B7007CY的高速电主轴用的混合式陶瓷轴承在轴向加载的过程中的接触椭圆的尺寸、最大接触应力和最大接触变形量的变化进行了计算机仿真；以琼斯的拟静力学设计分析方法为理论基础，采用外圈滚道控制理论，考虑离心力和陀螺力矩的影响，对不同转速条件下的混合式陶瓷轴承在轴向加载的过程中的内外套圈的轴向弹性趋近量、滚动体与外圈滚道的最大接触应力的变化进行了计算机仿真；对两种分别装有混合式陶瓷球轴承和钢轴承的高速电主轴进行了运转试验，对不同转速条件下滚动体的温升、电主轴的振动值进行了测试与分析。试验和仿真的结果表明，混合式陶瓷轴承是一种性能卓越的高速主轴轴承，尤其是在高速轻载的条件下。更多还原

【Abstract】 ased on the civil and foreign references of the ceramic ball bearings, in view of the Hertz space contact theory and the design of the steel ball bearings, this thesis simulated the changes of max contact stress, geometric parameters of contact ellipse and axial deformation of the ceramic ball bearing, which used in the high-speed electrical principal axis specially and typed with B7007CY, when the axial load is increased. Based on the simulating static mechanical design method, using the external raceway control theory, considering the centrifugal force and the gyro moment, this thesis simulated the changes of max contact stress between the rolling element and the external raceway and the axial deformation of the ceramic rolling bearings in different speed when the axial load is increased. The high-speed principal axis of fixed the ceramic ball bearings and the steel ball bearings were tested. The paper analyzes the testing results of the temperature-rise of the ceramic ball bearings and the vibrant of the high-speed electrical principal axis. All the results of the simulations and the experimentations indicated that the ceramic ball bearings’ performances are very good, especially in the low load and high-speed environment.更多还原
