The MOS bearing lubrication technical requirements

The role of the MOS pieces bearing lubrication bearing lubrication lubrication on the fatigue life of rolling bearing, friction and wear, temperature rise, vibration and so on have important influence, not normal lubrication, bearing cannot work. Analyze the failure reasons of bearing show that about 40% of the bearing damage is related to bad lubrication. Therefore, good lubrication of the bearing is an effective measure to reduce the bearing friction and wear. In addition, the bearing lubrication and cooling, a variety of action such as rust, seal, moderate impact. Grease lubrication grease is composed of base oil, thickener and additive of lubricants. When the choice, should choose to use condition is very suitable for bearing grease, because the trademark is different, also there will be a very big difference on performance, so when the choice, must pay attention to. Bearing the commonly used sodium calcium base grease, grease, grease sodium calcium base grease, lithium grease, aluminium base grease and molybdenum disulfide grease, etc. Number of filling grease in the bearing to 1/2 - full of bearing internal space A third as appropriate. When high speed should be reduced to one third. Too much grease will lead to higher temperature rise. Pieces of oil lubrication under the condition of high speed, high temperature, lubrication has not timely lubrication can be used. Through the circulation of lubricating oil, can take away a lot of calories. Viscosity is an important characteristic of lubricating oil viscosity, viscosity directly affect the liquidity of lubricating oil and the size of the friction surface is formed between the oil film thickness, the bearing working temperature of lubricating oil viscosity is usually 12 - 15cst。 Speed the Gao Yingxuan lower viscosity, the more load weight should choose high viscosity. Commonly used lubricating oil has high-speed machine oil, machine oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc. Technical requirements: the basic types of lubrication: the manufacturer brand lube oil temperature USES Exxon ( Exxon) Beacon synthetic grease - 325 55 ~ 120 general grease Exxon ( Exxon) Andok B ( Mil- G - Fat - 18709 a tank with oil 30 ~ 95 excellent quality of high speed, low torque, light Exxon ( Exxon) Andok C tank with oil grease 30 ~ 120 smooth operation, long service life, G.
