Plate rolling machine is a general equipment that rolls metal sheets into cylindrical, arc-shaped or other shaped workpieces. According to the principle of three points forming a circle, the relative position change and rotational motion of the workpiece are used to make the plate produce continuous plastic deformation to obtain a workpiece of a predetermined shape.
Plate rolling machines are widely used in boilers, shipbuilding, petroleum, woodworking, metal structures and other machinery manufacturing industries.
Reasons for excessive bearing temperature of plate rolling machine
When the plate rolling machine is running, the temperature of the bearings and other parts will rise rapidly due to the operation of the equipment. The operation of the equipment allows a certain temperature change, which is a normal phenomenon, but you should also be alert to the situation of excessive bearing temperature.
- Poor lubrication —- such as insufficient lubrication or over-lubrication, the quality of lubricating oil does not meet the requirements, deterioration or debris;
- Insufficient cooling —- such as pipeline blockage, improper cooler selection, poor cooling effect;
- Bearing abnormality —- such as excessive load on the plate rolling machine bearing, bearing damage, poor bearing assembly process or over-tight assembly, and the clearance adjustment of various parts of the bearing box does not meet the requirements;
- Large vibration —- such as poor coupling alignment process does not meet the requirements, the rotor has dynamic and static imbalance, poor foundation rigidity, weak footing, rotation stall and surge.
- Insufficient clearance —- If the clearance of the plate rolling machine mechanism assembly is insufficient, the bearing cage and rolling element will break, etc., which will cause the bearing temperature to be too high.
Conclusion
For newly installed and re-adjusted bearings, the temperature rise of the plate rolling machine bearing can be monitored by temperature measurement within a certain period of time to judge the installation and adjustment of the plate rolling machine bearing.
