How to solve the problem of SKF bearing heating

wallpapers Tech 2021-03-12
Maintaining a good bearing is a prerequisite for bearing operation. Common maintenance is for bearing lubrication. After reading how to choose the lubrication method of the bearing, it is also necessary to understand the maintenance of the bearing system under the premise of understanding the lubrication method of the bearing. The following analysis how to carry out SKF bearing lubrication maintenance.
Clean the bearing surface
Keep the bearing lubricated clean. Before inspecting SKF bearings, you should clean the surface of the bearing, and then carefully check the oil seal of the bearing and its surrounding parts. If a bad symptom appears, it must be replaced. A bad oil seal will cause damage., Make the bearing cloud shape abnormal and cause equipment shutdown.
Check lubricant
Check the lubricant of the bearing. Lubricant is very important not only for the bearing but also for all SKF bearings. But please note that it is not advisable to add too much grease to Japanese bearings. Then it is time to replace the lubricant of the bearing. Bearings lubricated with engine oil, after purging and removing the old engine oil, if possible, fill in fresh engine oil and let the machine rotate for a few minutes at a low speed. Try to make the oil collect residual contaminants, and then remove these oil. When replacing the grease with grease-lubricated bearings, the filter remover used should avoid any part of the bearing with cotton material coming into contact with it. Because these residual fibers may be wedged between the rolling elements and cause damage, especially bearing applications should pay attention to this problem.
Check the bearings
Pay attention to covering the exposed bearing, and do not expose the bearing to pollutants or moisture when checking the bearing. If work is interrupted, the machine should be covered with a greased paper plastic sheets or similar material. If the unmasked bearing is cleaned without disassembling and inspection may be performed, it should be cleaned with a paintbrush moistened with a petroleum solvent, and then wiped dry with a lint-free cloth or dried with compressed air.
Use a small mirror or a probe similar to that used by dentists to check the bearing track surface, retainer, and beads. Do not clean the sealed cover or dust-proof bearing, just wipe the outer surface. If the bearing is damaged, it needs to be replaced. It is much more economical to replace the bearing during the regular maintenance period than the loss caused by the sudden shutdown due to the damage of the bearing.
Through these 3 steps, your bearings can be well maintained, which greatly increases their service life and saves your operating costs. Not only the surface quality of SKF bearing workpieces is poor, but also the resistance to intergranular corrosion of the workpieces is reduced. When the SKF bearing workpiece is severely overheated, the crystal grains will be coarse, and at the same time, the amount of 8 iron cables in the steel will increase, which is easy to cause the deterioration of the hot workability of the workpiece.
