[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.
