Electric Spindle High-Speed Bearings Preferred Oil And Gas Lubrication
The role of lubrication:
Lubrication is an important factor in ensuring the normal operation of the bearing, bearing
capacity and service life are closely ralated. The effect of the lubrication on bearing life is
1.To reduce intermetallic friction, slow bearing wear, increase bearing life.
2.Lubrication from dust, rust, corrosion, can effectively ensure bearing life.
Oil and gas lubrication system has been gradually in the country has been the importance of
its many advantages in practice has gradually been the user certainly. The application of oil and
gas lubrication cooling technology has greatly improved the conditions of use of bearings, but
also improved and improved in terms of active cooling. Energy conservation and environmental
protection. It is more suitable for high load, high speed and high temperature conditions than
fuel injection, strong circulation lubrication cooling, is an effective lubrication method.
Compared with the traditional lubrication, there are many advantages:
1.Can transport a variety of performance indicators of lubricants. High Speed Motorized
Spindle Oil and Gas Cooling lubrication when lubricating oil is delivered, high viscosity
lubricants can be used. High viscosity lubricants can be quantitatively supplied to the bearing
site. Lubricant viscosoty increased, bearing oil film thickness and oil film formation rate will
be corresponding increase, which is to improve bearing life is very favorable.
2.Oil and gas lubrication can accurately control the amount of oil and gas. In the oil mist
lubrication, the amount of oil and gas can not be accurately adjusted. In the oil and gas cooling
and lubrication, the oil and gas is not one, you can adjust the amount of oil lubrication and
compressed air, the formation of oil and gas flow conditions to the lubrication point.
3.No environmental pollution. Oil mist lubrication, the oil was fog 0.5-2μm fog, particles,
some of these fog through the secondary solidfication into a larger oil droplets, play a role in
lubrication. But there are a lot of oil mist particles from the friction of the gap or seal to
the atmosphere emissions, causing environmental pollution. In the oil and gas cooling and
lubrication, the oil has not been atomized, but in the oil-like compressed air is blown and
transported, so the air is only the air emissions, so the environment without any pollution.
4.Good sealing and cooling performance. Lubricants in the role of friction point, not only
can prevent the metal and metal direct contact, as well as carry the role of friction and heat
sealing. Lubricants by external pollutants, water and other inrusive deterioration is one of the
important reasons leading to lubrication failure. In the past, oil lubrication and oil mist
lubrication, the bearing chamber pressure is low, so the sealing performance is relatively poor.
The oil and gas lubrication of the bearing cavity of the compressed air can be lubrication point
to play a cooling, dust, ani-harmful substances and so on.
The use of oil and gas lubrication system, due to the continuous flow of air, can take the
heat in the bearing cavity to keep the bearing at a reasonable temperature to work. The use of
oil and gas lunrication system, can form a positive pressure in the bearing cavity, but also
conductive to prevent water and impurities into the bearing inside, is conductive to the
formation of a good seal.
5.Low consumption of lubricating oil. Lubricant consumption when using oil and gas
lubrication is oil mist lubrication of 1/10, dry oil lubricationof 1/100.
6.Is conductive to improving the bearing speed. Because the oil droplets are in contact with
the friction surface of the spray, so the oil and gas mixture is fully capable of penetrating
through the high-speed operation due to the role of centrifugal force in the bearing around the
formation of air vortex, so as to achieve the purpose of jet lubrication and cooling.
