This paper deals with the influence of lubricating grease composition on grease service life and tribological performance characteristics in high-speed rolling bearings. First of all the test rig including the measuring system used to determine the lubricant film thickness in operation as well as the ...
Compared to other types of glycol coolants such as propylene glycol, ethylene glycol is more thermally conductive. This substance is also less viscous and flows more quickly, which is beneficial in heat transfer applications. A higher viscosity requires additional energy to move the substance through...

Six different types of greases were tested on the ball-on-disc test rig under starved condition. Both the central film thickness and the cross section film thickness profile were analyzed to better understand the mechanism of grease starvation. In-situ Monitoring of lubricant reservoir was achieved...
As shown in the Figures, the higher radius values were obtained especially with grease lubricant for brass specimens.Research limitations/implications - It would be interesting to search material flow for different materials and lubricants. It could be a good idea for future work could be ...
However, minimum friction at the interface seems to occur with the grease lubricant. The present analyses show that FEMs, which can be used in the rapid prediction of required barrelling process displacements, are more suitable for use in a pressure distribution analysis for the development of ...
lubricant liquid or grease, which is scattered in a fixed proportion of oil to liquid form, then activates the device and after a pre established time period is measured temperature zlewanego oil or the mixture of lubricant oil.then introduces to the same device, different lubricant from the ...
Rolling-Sliding FrictionSelf-Repairing FilmThe characteristics of the 1045 steel pairs using superfine mineral powder as grease lubricant additive were investigated by an AMSLER friction and wear tester at different wear states. The surface topographies and composition of the worn surface of 1045 steel ...
Grease-lubricated rolling element bearings can suffer from wear due to lubricant starvation under certain oscillating operating conditions. Especially for large-scale slewing bearings, such as blade bearings in wind turbines, experimental investigations are complex compared to small-scale reference testing. ...
