Lubrication is an important influence on the fatigue life of the vibrating screen rolling bearings and friction, wear, temperature rise, vibration, there is no normal lubrication, the bearings will not work. Vibrating screen bearings damaged in analysis showed that, about 40% of the vibrating screen bearing damage and poor lubrication. Therefore, a good bearing lubrication is an effective measure to reduce the bearing friction and wear. In addition, the bearing lubrication as well as heat, rust-proof, sealed, impact and other effects.

Vibrating screen bearing lubrication methods, divided into grease and oil lubrication. In order to make the bearing play function, first, to select the appropriate conditions of use, the purpose of the lubrication method. If only to consider lubrication, oil lubrication lubrication dominant. But the grease around the bearing structure can be simplified specialty.angular bearing

â—† grease lubrication

The grease is the lubricant composition by the base oil, thickener and additives. When selected, the choice is very suitable for the conditions of use of the vibrating screen bearings Run grease, different varieties, the performance will also be very different, so when selected, you must pay attention to.

Filling a grease lubrication can be done grease for a long time without refilling, and the structure of the sealing means is also relatively simple and therefore widely used.

Bearing grease calcium base grease, sodium based grease, calcium sodium grease, lithium grease, aluminum grease and molybdenum disulfide grease.bearing factory

The bearing grease filling quantity, filled inside the bearing space 1/2--1/3 as appropriate. The speed should be reduced to 1/3. Too much grease will make the temperature rise higher.

â—† oil lubrication

Oil lubrication can be used in high-speed, high-temperature conditions, were not suited to grease lubrication. Can be taken away by the circulation of the lubricating oil, a lot of heat, but also to reduce the vibration and reduce noise.

Divided into: (1) the drip lubrication oil bath lubrication (2) (3) splash lubrication (4) the spray lubrication cycle the lubricating (5) (6) Oil mist lubrication (7) oil and gas lubricationchina bearing supplier

â—† viscosity

Viscosity is the important characteristics of the lubricating oil, the viscosity of a direct impact on the size of the oil flow and friction surfaces asked to form the film thickness, the viscosity of the lubricant in the bearing operating temperature of the vibrating screen is generally 12 - 15 cSt. The higher the speed to be elected lower viscosity, load more weight should be selected high viscosity. Used mechanical oil, high-speed machinery oil, turbine oil, compressor oil, transformer oil, cylinder oil lubricants.
