High speed bearing lubrication

3. Double lubrication
This approach is essentially will turn the bearing inner ring of the hole and shaft neck hydrostatic oil film bearing, greatly reduced the speed of rotation bearing, so as to achieve the aim of reducing centrifugal force function, double lubricated bearing can significantly reduce the rotation of the bearing inner ring speed, and thus allow the spindle have higher speed, the equivalent of bearing the DMN value can be further progress Type Of SKF Bearings.
4. The lubrication oil and gas
Biggest advantage is without having to change the lubrication oil and gas bearing structure conditions, by reducing the bearing friction alone DMN value can be realized in 800000 ~ 1.5 million high-speed, for internal sliding bearing, the advantage of this approach is more apparent.
(1) the principle and characteristics of the oil and gas lubrication oil lubrication principle is to use quantitative piston distributor will be very tiny amounts of oil (such as 0.01 m1), with the best cycle intermittently discharge, discharge of oil before reaching the bearing form continuous flow along with the air into the bearing.
The characteristics of oil and gas lubrication is as follows:
1) can be extremely trace quantitative oil supply continuous steady bearing, so can control the necessary minimum like grease oil. Due to different bearing types, but also takes different amount of lubricating oil, the quantitative piston pipe to each bearing, so can adjust the bearing oil.
The lubrication method of friction loss is about one over ten of the splash lubrication, the kinetic friction loss and temperature rise is also smaller than grease lubrication.
