Way of bearing temperature during processing by lubricating spherical roller


There are pre-filled with grease greased sealed manner in sealed bearings, as well as inside the casing filled with the right amount of grease at regular intervals to supplement or replacement for grease filling mode. In addition, there are many excavator bearing  eed lubricating machinery, also uses the pipe connected to the lubrication at centralized way for fat. Grease filling can be done after the first time without grease supplement, and its structural sealing device is also relatively simple, so widely used. Lubricating oil is relatively simple. Regular lubrication can greatly improve the spherical roller bearing life Oh!
bearings when the temperature rises, first determine whether the error first move to do, if the temperature is indeed rising, Dangdang that do the following disposition:
(1) Check the cooling water pressure, flow and piping system can generally bearings. If water filter may be clogged down, can not timely disposal of hot disassembly spherical plain bearings ylindrical bore bearings can shut down the disposal, can work when the confirmation is done, then put into use.
(2) When the check governor oil pressure, oil pressure may result if the cooling water hydraulic valve closed.
(3) check whether no bearing spherical ball with the outside of the soundtrack, and can not detect bearing swing very much.
(4) to take oil samples to see whether the oil did not change color, bearing and conduct tests to see whether the variables. If confirmed deterioration, stop change when the new oil.
(5) Check the oil standard oil level can generally, if the non-general, check whether the tank drain valve closed. If the bearing is not closed, when up the oil, if oil leakage sealing pads, when stopping for disposal.
Bearing lubrication performance can be divided into the following areas:
1, the first portions of lubricating spherical roller bearings, reducing bearing friction and wear;
2, the rolling contact surfaces of the bearing oil film often form appropriate to extend the fatigue life of the bearing;
3, through the heat inside the bearing lubrication away due to friction or other causes;
4, by ship loader bearing lubrication to the role of rust and dust.
