Under normal circumstances; the amount of smooth grease filled in TIMKEN cylindrical roller bearings; always exceeds the amount of practice required to directly participate in smoothness; in the cavity on the frame and bearing cover; and constitutes a generalization on the periphery of the roll In the process; because of the resistance of the remaining smooth grease; the bearing temperature rises quickly. Although most of the remaining smooth grease is squeezed out at the beginning of the work; and the smooth grease squeezed in the raceway attachment can still be transformed. The tumbling body is brought into the raceway. These are during the initial period of the bearing work; most of the smooth grease is squeezed out of the raceway very quickly (less than a minute); and the accumulation of smooth grease is followed by the transformation of the TIMKEN cylindrical roller bearing. The body cycle is discharged together; a few consecutively discharged. At this time, the bearing temperature continues to rise; until the remaining smooth fat is completely discharged; it can be called the smooth grease during the running; according to the bearing layout, the smooth grease quality, filling amount, etc. Elements; this moment can continue for ten minutes; even hours.
After the remaining smooth grease is completely discharged; the remaining few smooth greases are on the touch surface of the tumbler, the raceway, and the support frame; the cusp effect forms a thin layer of smooth lipid film; then enters the normal working period of the bearing. At this time, the temperature gradually decreases and reaches equilibrium. That is to say; long-term smoothing effect; mainly relying on this layer of smooth grease film to undertake. In addition; in the long-term working of the bearing; generalization of the rolling body and the raceway The smooth grease on the top and the shelf must be shrunk to separate a part of the base oil; after flowing into the raceway; there is also a certain compensation effect on smoothness.
Different smooth greases are different in the TIMKEN cylindrical roller bearings. It must be composed in a general analogy; the running time is short; the bearing temperature is low during long hours of work; and it is stable; It is a kind of smooth fat that is more ambition; so it is especially important for the smoothness of smooth fat.
Some so-called eddy-type smooth greases are otherwise; it is not easy to constitute a generalization; even if it constitutes a generalization, it simply collapses; at this time, the remaining smooth grease that is repeatedly returned to the raceway is in a state of being strongly mixed for a long time; the torque of the TIMKEN cylindrical roller bearing is large. ; high temperature; and unbalanced; can also produce noise; smooth grease is also simple metamorphosis and loss.
