When the the smooth fat from external force, like a solid adhere to a certain shape, that does not automatically lose the rest.
Was very high shear stress conditions (shear rate), smooth and butter activities like Newtonian fluid, viscosity can adhere to a constant, rather than with the shear rate of the changes and alterations.
Showing the elasticity characteristic of the solid after removal of the external force can return to the original position and shape, when was a slight external force, resulting in the elastic deformation;
When the external force applied is large enough, and the onset of smooth lipid strain and activities and therefore can no longer be automatically restored to the original position and shape, and thus smooth lipid starting torque on the mechanical operation member is larger than the liquid lubricating oil.
High ambient temperature, smooth grease does not conform to forging machine move bearing with molybdenum disulfide smooth fat is thought to high temperature grease, we know its bedrock oil are petroleum products, plus a small amount of high temperature molybdenum disulfide additive, its temperature limit is 120 ℃. And the machine lubricator point up 30 places, unable to complete long-term operation and maintenance of such a cumbersome the oiling disposable, had to hand-held the dilute the oiler poured operation outside of the bearing sleeve, smooth oil is difficult to enter the bearing friction pair, large department The bearing is in frictional state.
According to the measured forging machine bearing operating temperature of up to 200 ° C, have gone far beyond the smooth grease temperature limit. In such a high temperature under the premise smooth fat bedrock oil becomes thinner and gradually evaporated and the rest of the carbon residue, molybdenum disulfide, dust mixed into a solid block of solidified adhere rack move bearing, not only lost its smoothness also barriers to move the normal operation of the bearing wear out quickly, up to two weeks you have to shut down, remove the bearing cleaning a new grease.
Wide temperature range since the use of the smooth bearing adequate content of solid smooth, uniform release and having good self smooth functioning and seizure resistance, can effectively maintain the journal, to reach the purpose of durable use.
