1. Reasons for the increase in bearing temperature
-
The contact point on the surface of the shaft tile is small, and the contact surface is insufficient, which does not meet the equipment specifications.
-
The increase in bearing clearance is far greater than the clearance required by the design. As a result, it is not easy to form an oil wedge when the lubricating oil enters the bearing pad surface, resulting in poor lubrication, leading to an increase in the temperature of the guide bearing and an increase in unit vibration.
2. The solution to the temperature rise of the guide bearing
When lubricating the ceramic tile surface, even though the maximum swing point of the spindle is passed, the matching gap is the smallest, but due to the short distance, good lubrication conditions, less heat generated by friction, and good cooling effect, it will generally not cause bearing temperature rise, nor will it cause The tiles are burning.
