Lubricant is an essential and necessary condition for the bearing to operate. It is an important adjustment to reduce bearing wear and improve bearing life.
Lubricant is an essential and necessary condition for the bearing to operate. It is an important adjustment to reduce bearing wear and improve bearing life. The lubrication methods of imported bearings can be divided into grease lubrication and oil lubrication. Different imported bearings have different uses. The method and the lubrication method used are also different. The following Demerui Bearing will share with you the influence of the choice of imported bearing lubricants on the bearing.
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 method of vibration eccentric bearing lubrication is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to select a lubrication method suitable for the conditions of use and the 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 choosing, you should choose the lubricating oil that is very suitable for the service conditions of the eccentric bearing. Due to the different varieties, there will be great differences in performance, so you must pay attention when choosing.
2. Eccentric bearing oil lubrication
Under the condition of high speed and high temperature, 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 vibration and noise of eccentric bearings.
3. Grease viscosity of eccentric bearing
The viscosity of imported bearings is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of the lubricating oil and the thickness of the oil film formed on the friction surface. The viscosity of the lubricating oil at the working temperature of the vibrating eccentric bearing is generally 12--15cst. The higher the rotation speed, the lower the viscosity should be selected, and the heavier the load should be, the higher viscosity should be selected. Commonly used lubricating oils include mechanical oil, high-speed mechanical oil, steam turbine oil, compressor oil, transformer oil, cylinder oil, etc.
