Rolling bearings are also a commonly used type of mechanical hardware product, and they require continuous lubrication treatment during use to ensure their normal operation. So, what are the main purposes of lubrication treatment for rolling bearings? What are the methods of lubrication treatment? Today, the editor has compiled the following information for you, hoping to help more people have an understanding and recognition of this type of bearing!
The main purposes of lubrication for rolling bearings are:
1. Reduce friction and wear: In the contact parts between the rings, rolling elements, and retainers that make up the bearing, prevent metal contact and reduce friction and wear.
2. Extended fatigue life: The rolling fatigue life of bearings is extended when the rolling contact surface is well lubricated during rotation. On the contrary, if the oil viscosity is low and the lubricating oil film thickness is not good, it will be shortened.
3. Discharging frictional heat and cooling: Circulating oil supply method can use oil to discharge heat generated by friction or heat transmitted from the outside for cooling. Prevent bearing overheating and prevent lubricating oil from aging on its own.
4. Other: It also has the effect of preventing foreign objects from entering the interior of the bearing, or preventing rust and corrosion.
The main methods of lubrication for rolling bearings are:
At present, there are two different lubrication methods for bearings: grease lubrication and oil lubrication; In order for bearings to function well, the first step is to choose a lubrication method that is suitable for the usage conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication has the advantage. However, grease lubrication has the advantage of simplifying the structure around the bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication.
