Consulting bearing grease lubrication affect life in the damp environment

Bearing in damp environment, condensate will be formed in the rolling bearing and cause corrosion, lead to bearing life shortened, through careful choice lubricating grease, can reduce the influence of condensation moisture. By sodium soap thickened fat absorption moisture ability is strong, but because of too much moisture absorption and softening, outflow of bearing; Lithium soap grease not moisture absorption, but by adding proper additives. Can provide good corrosion resistance, some fat containing synthetic thickener can provide excellent corrosion resistance, prolong the life of bearing. Lubrication ( A) Bearing lubrication effect of 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, sealing, rust and moderate impact of a number of roles, the effect of bearing lubrication can be briefly stated below: a. The contact between two rolling or sliding surface formed between a layer of oil film separates two surface, reduce the friction and wear of contact surface. 1) technical data Bearing lubrication effect of 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. Because of this, good lubrication of the bearing is an effective measure to reduce bearing friction and wear. In addition, bearing lubrication and cooling, antirust and seal, a variety of action such as moderate impact. 2) Grease lubrication grease is composed of base oil, thickener and additive of lubricants. When the choice, should choose is very suitable for bearing conditions of the use of grease, because the trademark is different, also there will be a very big difference on performance, so when the choice, must pay attention to. 3) 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. 4) 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 - 18cst。 Speed the Gao Yingxuan lower viscosity, the more load weight should choose high viscosity. Commonly used lubricating oil machine, high-speed machine oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc. WT toleranceof 6年级/ ABEC3如下d ( mm) △dmp Vdp ( Diameter series) Vdmp Kia delta Bs Vbs 9 0, 1, 2 and 4 more than over to the to the Max Max min min maximum Max Max maximum Max Max Max min min Max. 2. 10 0 0 7 and 9 7 5 5 0 to 5 15 10 18 0-120 7 and 9 7 5 5 0 to 7 20 18 30 0-120 10 8 August 6 6 0 to 8 120 20
