Lubricant is an indispensable condition for bearings during operation. It is an important adjustment to reduce bearing wear and increase bearing life. The lubrication methods of imported bearings can be divided into grease lubrication and oil lubrication. Different imported bearings have different uses. Methods and lubrication methods used are also different. Below, Demeirui Bearing will share with you the impact of the selection of imported bearing lubricants on bearings.
Lubrication has an important impact on the fatigue life, friction, wear, temperature rise, vibration, etc. of imported eccentric bearings. Without normal lubrication, eccentric bearings cannot work. Analysis of the causes of vibration eccentric bearing damage shows that about 40% of vibration bearing damage is related to poor lubrication.
The lubrication methods of vibration eccentric bearings are divided into grease lubrication and oil lubrication. In order for the bearing to function well, first of all, it is necessary to choose a lubrication method suitable for the use conditions and purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing.
1. Eccentric bearing grease lubrication
Grease is a lubricant composed of base oil, thickener and additives. When selecting, you should choose a grease that is very suitable for the use conditions of eccentric bearings. Due to different varieties, there will be a big difference in performance, so you must pay attention when selecting.
2. Eccentric bearing oil lubrication
Under high-speed and high-temperature conditions, oil lubrication can be used when grease lubrication is no longer suitable. Through the circulation of lubricating oil, a large amount of heat can be taken away, and it is also effective in reducing the vibration and noise of the eccentric bearing.
3. Grease viscosity of eccentric bearings
The viscosity of imported bearings is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of lubricating oil and the thickness of the oil film formed on the friction surface. The viscosity of lubricating oil at the operating temperature of vibrating eccentric bearings is generally 12--15cst. The higher the speed, the lower the viscosity, and the heavier the load, the higher the viscosity. ·Commonly used lubricating oils include machinery oil, high-speed machinery oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc.
During the storage and operation of imported bearings, reasonable use of lubricating oil can reduce bearing losses and enhance the service life of bearings.
