Comparative study on corrosion resistance and lubrication function of lithium complex grease and polyurea grease

open access: yesFriction, 2019
In this study, lithium complex grease (LCG) and polyurea grease (PUG) were synthesized using mineral oil (500SN) and polyalphaolefin (PAO40) as base oil, adsorbed onto lithium complex soap and polyurea as thickeners, respectively.

Grease [PDF]

open access: yes, 2022
Everybody has made use of grease in their daily lives. The word “grease” originates from the early Latin word “crassus,” meaning fat. For our purposes, in this Special Issue, we will be focusing on lubricating grease, for publication in the eponymous ...

Towards adaptive grease lubrication

open access: yes, 2006
Currently used rolling bearings are in most cases grease lubricated. The annual grease consumption at a paper mill or a steel works, for example, is typically between 3000 and 8000 kg, the majority of which is used for lubricating rolling bearings [1 ...

Characterization of Acoustic Emissions from Journal Bearings for Fault Detection [PDF]

open access: yes, 2013
Acoustic emission (AE) technology is one of the most established diagnostic techniques for rolling bearing monitoring in rotating machinery. The application of high-frequency AE for bearing diagnosis is gaining acceptance as a useful complimentary tool.

Sliding Friction Characteristics of MAC Greases under Vacuum Condition

open access: yesTribology Online, 2006
Even though solid lubricants or low-volatile greases are used for lubrication of mechanical equipments in space satellites, the life of grease is longer than that of solid lubricants because of the hydrodynamic effects and replenishment. New grease using

Research on Key Technologies of Temperature Rise Suppression for Motor Grease Lubricated Rolling Bearing

open access: yes机车电传动, 2020
At present, grease lubrication is widely used in motor rolling bearings. However, the bearing DN value increases rapidly with the increasing of motor speed and power for the factor that the lubricating grease is semi-solid with poor flow and heat ...
