摘要：
The vibration of four-point contact ball bearing for power transmission mechanism was studied. A vibration analysis model of the four-point contact ball bearing considering lubrication was established. Taking QJ214 four-point contact ball bearing as an example, the vibration characteristics of the bearing under different structural parameters and working conditions were analyzed theoretically. The results showed that the smaller the radial clearance and the number of rolling elements of the four-point contact ball bearing, the smaller the bearing vibration; the curvature radius coefficient of the inner and outer ring grooves has a greater influence on the bearing vibration, and a reasonable choice of the inner and outer ring groove curvature radius coefficient can effectively reduce the bearing vibration; lubricant can alleviate vibration impact and reduce the vibration of the bearing; applying a reasonable axial load to the four-point contact ball bearing can reduce the vibration of the bearing. © 2023 Chinese Vibration Engineering Society.
