【摘要】：目的解决精密轴承现有包装在运输过程中受到振动和冲击影响易导致其接触面间的表面质量下降的问题。方法提出了一种刚柔结合的精密轴承包装方法,通过预紧力定位装置消除轴承滚动体与内圈两者间游隙,结合缓冲衬垫对包装件进行防护。通过应力-应变原理设计预紧力定位装置结构,并利用有限元软件模拟该装置与轴承相互作用的工作过程,研究该过程中轴承受力变化情况及预紧装置的力学表现。结果仿真结果显示定位装置对轴承施加预紧力后游隙消失,且轴承的弹性变形在可承受范围内。通过对整体包装件进行自由跌落试验,测得轴承受到的冲击加速度小于50G,并检测轴承接触表面无损伤。结论所提出的精密轴承包装方法能够对精密轴承提供保护作用。
[Abstract]:Aim to solve the problem that the impact of vibration and shock on the current packaging of precision bearings can lead to the deterioration of the surface quality between the contact surfaces. Methods A rigid and flexible packing method for precision bearing was proposed. The clearance between the rolling body and the inner ring of the bearing was eliminated by the pretightening force positioning device, and the packaging was protected by the cushioning pad. Based on the stress-strain principle, the structure of the pretightening force locator is designed, and the working process of the interaction between the device and the bearing is simulated by using the finite element software. The mechanical behavior of the preloading device and the bearing force change during the process are studied. Results the simulation results show that the clearance disappears after the pretightening force is applied by the positioning device and the elastic deformation of the bearing is within the tolerable range. The free drop test of the whole package shows that the impact acceleration of the bearing is less than 50 Gand the contact surface of the bearing is not damaged. Conclusion the proposed packaging method can provide protection for precision bearing.
