Use smooth grease correctly; It is necessary to know the movement of smooth grease in Timken cylindrical roller bearing Ensure the stability of smooth grease Movement of smooth grease filled in the roll bearing; Follow the rotation of Timken cylindrical roller bearing; Generally speaking, it can be divided into two periods
Under normal circumstances; Filling amount of smooth grease in Timken cylindrical roller bearing; It always exceeds the need for direct Correct Application participation in smooth practice; On the holder and in the cavity of the bearing cover;
A generalization is formed on the periphery of the rolling body In this process; Because of the resistance of the remaining smooth grease; The Correct Application bearing temperature rises rapidly Although most of the remaining smooth grease is extruded at the beginning of work;
And the smooth grease squeezed in the raceway accessories can still be brought into the raceway by the Correct Application transformed rollover body These are during the initial stage of bearing operation;
Most smooth grease is squeezed out of the raceway quickly (less than a minute); The grease accumulated on the surface keeps smooth and Correct Application circulates with the transformation body of Timken cylindrical roller bearing; A small number of are discharged continuously
At this time, the bearing Wendu continues to rise; Until all the remaining smooth grease is Correct Application discharged and stopped; It can be called the running in period of smooth grease; According to the smooth grease quality, filling amount and other factors in the bearing layout; This time can continue for more than ten minutes; Even a few hours
A small amount of remaining smooth grease is on the mutual touch Correct Application surfaces of the tumbling body, raceway and persistence frame; A thin layer of smooth lipid membrane is formed by the wedge effect;
Then enter the normal working period of the bearing At this time, the Correct Application temperature gradually decreases and reaches equilibrium in other words; Long time smoothing effect; It is mainly supported by this smooth lipid membrane In addition; During the long-time operation of the bearing;
The smooth grease on the roller body and near the raceway and on the holding frame shall shrink and Correct Application separate part of the base oil; After flowing between raceways; It also has a certain compensating effect on smoothness
The composition of different smooth grease in Timken cylindrical roller bearing is different; Must constitute a general comparison and write a manuscript; Short running in time; The bearing temperature is low during long-time operation; And stable; This is an ideal smooth grease; Therefore, it is particularly important for the channelization of smooth grease
Some so-called vortex smooth greases are otherwise; It is not easy to form a summary; Even if it constitutes a summary, it is simple to fall;
At this time, the remaining smooth grease repeatedly returned to the raceway is strongly mixed for a long time; Timken cylindrical roller bearing has large torque; High temperature; And unbalanced; Noise can also occur; Smooth grease is also simply metamorphosed and lost
