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 the vibration of the unit.
Second, the solution to the temperature rise of the guide bearing
When lubricating the surface of the ceramic tile, even if the maximum swing point of the spindle is passed, although the matching gap is the smallest, the distance is short, the lubrication condition is good, the heat generated by friction is less, and the cooling effect is good. Generally, it will not cause the temperature rise of the bearing, nor will it cause The tiles are burning.
