Rolling and sliding bearings lubrication method is different.
Lubricant
Effect of lubricant to reduce friction, reduces wear, cooling and vibration absorber, lubricant liquid, solid and gas and semisolid, liquid lubricant known as lubricant, partially solid, solid at room temperature grease for lubricating grease.
Lubricating oil
Lubricating oil is a major lubricant is the main physical properties of lubricating oil viscosity, viscosity characterization of internal friction of flow properties, viscosity, the greater, its poor mobility. Other physical properties of lubricating oil is oily, characterization of adsorption capacity of lubricating oil on the metal surface. Oil, the larger metal adsorption ability comes great film is difficult. Selection of lubricating oil balance INA the carrying capacity of the bearing, axle speeds, lubrication, the bearing surface roughness and other factors.
The General principles are as follows:
1, work in high speed light load conditions, in order to reduce friction and to select the lubricant viscosity small power consumption;
2, work overload or shock load conditions, the oil, viscosity of the lubricant should be used to form stable lubricating film;
3, static pressure or hybrid journal bearing optional small viscosity lubricant;
4, surface roughness, or without the running surface of high viscosity lubricants should be selected.
Selection of hydrodynamic lubrication bearing oil viscosity, can be calculated for checking.
Grease
Axis neck speed is less than 1 m/s~2 m/s of bearing can used grease, grease is with mineral oil, and various heavy of agent (as calcium, and is satisfied that, and lithium, and aluminum, metal SOAP) and water reconcile and into, grease of consistency (needle into degrees) large, hosted capacity large, but physical and chemical nature not stability, should not be in temperature changes large of conditions Xia using, more for speed overload or swing of INA bearing in the.
Solid lubricants and gases lubricants
Solid lubricant with graphite, molybdenum disulfide (MoS2) and Teflon (PTFE) and other varieties. General under overload conditions, or use under high temperature conditions. Gaseous lubricants commonly used air, used for speed and can not use oil or grease.
Methods of lubrication
Provided to the INA bearings lubricant is essential for forming lubricating films, static pressure bearing and hydrostatic bearings are through the oil pump, throttle and oil trench, to the Bush bearing continuous oil supply, form oil film bearing and axle journal surface apart. Sliding bearing oil film is turning oil into the bearing clearance of the shaft, its oil supply continuous and intermittent oil supply for oil.
